If I understand him correctly, Derek Parfit’s views place us, philosophically speaking, in a very small box. According to Parfit, normativity is an irreducible non-natural property that is independent of the human mind. That is to say, there are normative truths - truths about what we ought to do and to want, or about reasons for doing and wanting things. The truths in question are synthetic a priori truths, and accessible to us only by some sort of rational intuition. (...) Parfit supposes that if we are to preserve the irreducibility of the normative, this is just about all we can say, at least until we bring in some actual intuitions to supply the story with some content.

This dissertation is a critique of synthetic ethical naturalism (SEN). SEN is a view in metaethics that comprises three key theses: first, there are moral properties and facts that are independent of the beliefs and attitudes of moral appraisers (moral realism); second, moral properties and facts are identical to (or constituted only by) natural properties and facts (ethical naturalism); and third, sentences used to assert identity or constitution relations between moral and natural properties are expressions of synthetic, a (...) posteriori necessities. The last of these theses, which distinguishes SEN from other forms of ethical naturalism, is supported by a fourth: the semantic contents of the central moral predicates such as 'morally right' and 'morally good' are fixed in part by features external to the minds of speakers (moral semantic externalism). Chapter 1 introduces SEN and discusses the most common motivations for accepting it. The next three chapters discuss the influential "Moral Twin Earth" argument against moral semantic externalism. In Chapter 2, I defend this argument from the charge that the thought experiment upon which it depends is defective. In Chapters 3 and 4, I consider two attempts to amend SEN so as to render it immune to the Moral Twin Earth argument. I show that each of these proposed amendments amounts to an abandonment of SEN. Chapter Five explores Richard Boyd's proposal that moral goodness is a "homeostatic property cluster." If true, Boyd's hypothesis could be used to support several metaphysical, epistemological, and semantic claims made on behalf of SEN. I advance three arguments against this account of moral goodness. In the sixth chapter, I argue that moral facts are not needed in the best a posteriori explanations of our moral beliefs and moral sensibility. Because of this, those who accept a metaphysical naturalism ought to deny the existence of such facts or else accept skepticism about moral knowledge. In Chapter 7, I consider a counterargument on behalf of SEN to the effect that moral facts are needed in order to explain the predictive success of our best moral theories. I show that this argument fails. (shrink)

Peirce did not achieve a final systematization of his work. Beyond the difficulties in explaining so many philosophical tools that he introduced—suffice it to mention semiotic, abductive logic, a heuristic based on continuity, scholastic realism—, there is a theoretical reason for this incompletion. All those new philosophical tools indicated a conception of synthesis very different from the one he received from Kant. Peirce did not realize the profound direction of his enquiry so that he did not directly question neither Kant’s (...) legacy on this issue nor the idea of necessity that presides over it. Starting from Peirce’s conception of continuity and change, this paper will give a new definition of synthetic and analytic judgments and reasoning, completing the picture with a third “vague” judgment and reasoning. In this new definition a synthetic judgment is a judgment that recognizes identity through changes. An analytical judgment is a judgment that loses identity through changes. A vague judgment is a judgment that it is blind to identity through changes. How do we perform synthetic reasoning? Following Peirce’s semiotic study of elements of Gamma Graphs as the sheet of assertion and the line of identity, the paper will first individuate the semiotic characteristics necessary for the recognition of identity. These characteristics lead us to discover “complete gesture” as the tool that we use in our every-day reasoning in order to acquire new knowledge synthetically. “Complete gestures” are actions through which we carry and recognize significant meanings. This new paradigm should provide an improved account of common-sense knowledge as well as of particular creative and hypothetic stages of conception in both scientific and humanistic thought.

The purpose of this paper is to analyze the theoretical commitments of autopoietic enactivism in relation to Errol E Harris’s dialectical holism in the interest of establishing a common metaphysical ground. This will be undertaken in three stages. First, it is argued that Harris’s reasoning provides a means of developing enactivist ontology beyond discussions limited to cognitive science and into domains of metaphysics that have traditionally been avoided by phenomenologists. Here, I maintain enactivist commitments are consistent with Harris’s reasoning from (...) certain synthetic a priori first principles, to his derivation of a teleological anthropic principle, which asserts the necessity of consciousness within the cosmos. Second, it is proposed that Steven Rosen’s long-standing proposal for a topology of phenomenology may provide a common logical foundation for both Harris and enactivists regarding anthropic reasoning. Third, it is argued that a pragmatic approach to process ontology is the most rigorous way of responding to the realism/anti-realism concerns that inevitably follow. If successful, this work will update Harris’s arguments with contemporary scientific and philosophical terminology and extend enactivism from philosophy of mind, into a general phenomenological ontology.

KANT’S GOAL IN THE TRANSCENDENTAL DEDUCTION was to demonstrate that the categories are applicable to objects of sensible intuition. He carried out this task by disclosing the necessity of a transcendental synthesis. In the Transcendental Deduction in the second edition of the Critique of Pure Reason transcendental synthesis has two subspecies: synthesis intellectualis and synthesis speciosa. The distinction between the two types of transcendental synthesis is also mirrored in the structure of the proof of the B Deduction. As several (...) commentators have noted, the B Deduction in fact contains two parts. Each part seems to provide an account of a distinctive kind of transcendental synthesis. The first part provides an account of intellectual synthesis while the second part provides an account of figurative synthesis. (shrink)

Several authors have detected profound analogies between Kant and Wittgenstein. Their claims have been contradicted by scholars, such being the agreed penalty for attributions to authorities. Many of the alleged similarities have either been left unsubstantiated at a detailed exegetical level, or have been confined to highly general points. At the same time, the 'scholarly' backlash has tended to ignore the importance of some of these general points, or has focused on very specific issues or purely terminological matters. To advance (...) the debate, I distinguish four different topics: questions of actual influence; parallels at the methodological level; substantial similarities in philosophical logic; substantial similarities in the philosophy of mind. The article concentrates on the second and third topic. Section I argues that the critical conception of philosophy shared by Kant and Wittgenstein is itself due to the fact that they explain the a priori status of necessary propositions by reference to the way we experience or represent reality. Section II shows how the Tractatiis linguistically transforms this 'reflective turn', replacing Kant's preconditions of experience by preconditions of symbolic representation. Section III suggests that this explanation of the a priori involves the idea of an isomorphism between thought and reality, and that both Kant's transcendental idealism and Wittgenstein's early metaphysics of symbolism distort this isomorphism. Wittgenstein later rejected this metaphysics of symbolism, on the grounds that language is autonomous, and section IV detects parallels between that idea and Kant's 'diallelus' argument against the correspondence theory of truth. Finally, I claim that while Wittgenstein is right to insist that all a priori propositions are conceptual, Kant, in calling them synthetic a priori, is right to deny that they simply unpack the concepts involved in the propositions themselves.

Throughout his philosophical career, Hilary Putnam was preoccupied with the question of what survives of the traditional notion of a priori truth in light of the recurring historical phenomenon, made prominent by the scientific revolutions of the early decades of the twentieth century, through which “something that was literally inconceivable has turned out to be true”. Impugning the analytic-synthetic dichotomy, Putnam’s redefinition of “conceptual truth” in terms of “quasi-necessity relative to a conceptual scheme” is meant to accommodate the (...) possibility of transitions of just this sort. In this essay, I trace the origins and development of Putnam’s account of “quasi-necessity.” I try to defend it against some objections naturally arising in connection with the interplay of modality and negation. My main contention is that the main tenets of Putnam’s semantic externalism inform his reconception of conceptual truth, and that they must be recognized to hold of such basic logical notions as those of judgment and negation.

Sympathetic commentators on Kant’s account of physical knowledge agree that while philosophy of science has much to gain from Kant’s notion of constitutive a priori principles, Kant’s conceptual and methodological resources are inconsistent with the possibility of scientific change. In this article, I argue that this received view is lacking since Kant’s claim that a unique set of a priori principles structures our knowledge for all time is not central to his account of the constitutive a priori. Two underemphasized points (...) of Kant’s theory bear this out. First, Kant applies ‘a priori’ widely to include non-truth-evaluable elements of knowledge. As such, Kant primarily understands the necessity that attaches to these elements in light of the constitutive role they play in knowledge rather than in terms of truth for all time. Second, Kant uses two methods to establish the existence of constitutive a priori principles: the analytic and the synthetic. On my interpretation, while scientific change has discredited the analytic method, the synthetic method remains viable. In this way, I offer a new perspective on the ways in which Kant’s theory of the constitutive a priori can ground Neo-Kantian philosophies of science like those of Hans Reichenbach and Michael Friedman.

The text considers the possibility of studying the Freudian psychoanalysis as a certain form of transcendentalism. In particular, it analyses the relation of Freud’sproposition concerning the strangeness within the subject—a strangeness called unconsciousness—to Kant’s claim about the necessity of the synthetic unity ofapperception. The study commences with Ricoeur’s reading of Freud’s teachings in order to demonstrate how, by introducing the language of transcendental philosophy into the reading of Freud’s works, Ricoeur omits the issue of the subjective conditions for (...) the constitution of any possible meaning. Next, searching for the possibility to formulate these conditions on the grounds of Freudian psychoanalysis, the text investigates relevant Heidegger’s reading of Kant. It finds in it the model justification for such understanding of the unity of “I think” which makes it, already at its core, conditioned by diversity identified with temporality. By attempting to grasp the contradiction between such a temporal condition for subjectivity and Freud’s postulate on the timeless nature of unconsciousness, the text applies Derrida’s criticism of the metaphysical conception of time, which is directed exactly at Heidegger’s metaphysics of Dasein. In consequence, it turns out that a profound justification seems to exist for the seemingly paradoxical Freudian statement about unconsciousness as linked with, on the one hand, the most primal intuitions still grounded in animism, and on the other, with a continuation of Kant’s teachings.

ABSTRACT There is general agreement that Kant’s thought strongly influenced Heidegger’s. Nevertheless, there is still much work to be done in order to fully appreciate this influence. A central theme to disclose the relation between these authors is the role they give to the transcendental. In this paper I show that Kant’s account of intuition is the focus of Heidegger’s interpretation of Kant in his Die Frage nach dem Ding, since Heidegger interprets Kant’s treatment of intuition as a delimiting of (...) the modern mathematical tendency to determine everything out of pure reason alone. I argue that this interpretation is at the basis of Heidegger’s appropriation of Kant’s synthetic a priori in this work, the aim of which is to take this notion away from the sphere of the objects of mathematical physical science, and place it in the realm of everyday experience. I claim that Heidegger thinks that this move can only be accomplished by removing universality and necessity from Kant’s a priori. Finally, I show that Heidegger’s appropriation of Kant’s synthetic a priori goes together with and illuminates his understanding of transcendence as das Zwischen, ‘the between us and things’. RESUMO É consenso geral que o pensar de Kant influenciou fortemente o pensar de Heidegger. Porém, há ainda muito trabalho a fazer para se conseguir apreciar essa influência plenamente. Um tema crucial para conseguir expor a relação entre esses dois autores é o rol que ambos dão ao transcendental. Neste artigo, vou mostrar que o tratamento que Kant faz da intuição é o foco da interpretação que Heidegger oferece acerca de Kant em sua obra Die Frage nach dem Ding, dado que Heidegger interpreta o jeito como Kant trabalha a intuição como uma delimitação da tendência matemática moderna a determiná- lo tudo pelo só uso da razão pura. Argumento que essa interpretação está na base da apropriação que Heidegger faz do sintético a priori kantiano nesta obra, cujo fim é tirar essa noção fora da esfera dos objetos da ciência físico- matemática e posicioná-la no reino da experiência cotidiana. Sustento que Heidegger pensa que isto só pode ser alcançado ao eliminar a necessidade e a universalidade do a priori kantiano. Finalmente, mostro que a apropriação que Heidegger faz do sintético a priori kantiano vai junto e ilumina sua compreensão da transcendência como o das Zwischen, ‘o entre nós e as coisas’. (shrink)

In the nineteenth century, the separation of naturalist or psychological accounts of validity from normative validity came into question. In his 1877 Logical Studies (Logische Studien), Friedrich Albert Lange argues that the basis for necessary inference is demonstration, which takes place by spatially delimiting the extension of concepts using imagined or physical diagrams. These diagrams are signs or indications of concepts' extension, but do not represent their content. Only the inference as a whole captures the objective content of the proof. (...) Thus, Lange argues, the necessity of an inference is independent of psychological accounts of how we grasp the content of a proposition. (shrink)

This synthetic review aims to unite a seemingly disjoint collection of studies over the past 3 decades around their shared examination of sexism in an often overlooked U.S. population, namely girls attending private Christian schools. This undertaking reveals substantial harms that I categorize as those of immediacy and potentiality, which are occurring behind the protective wall separating church and state. Contra the majority of philosophers of education and researchers in this area, these studies lead me to argue that the (...) state has the obligation and legal ability to intervene in this private domain. Notably, this study begins to flesh out a notion of educational harm that may be robust enough for state policy making and legal action in private schools. Based on a legalized understanding of sexist harm, I conclude with a detailed analysis of Constitutional provisions and court decisions relative to state intervention and freedom of religious practice.

The article examines how Salomon Maimon’s concept of number as ratio can be used to demonstrate that arithmetical judgments are analytical. Based on his critique of Kant’s synthetic a priori judgments, I show how this notion of number fulfills Maimon’s requirements for apodictic knowledge. Moreover, I suggest that Maimon was influenced by mathematicians who previously defined number as a ratio, such as Wallis and Newton. Following an analysis of the real definition of this concept, I conclude that within the (...) framework of Maimon’s philosophy, arithmetical judgments cannot be analytical, nor is arithmetic an objectively necessary science, but rather only subjectively necessary. We should also cast doubt on his claim that we can create real objects from pure concepts of the understanding. (shrink)

In an effort to account for our a priori knowledge of synthetic necessary truths, Kant proposes to extend the successful method used in mathematics and the natural sciences to metaphysics. In this paper, a uniform account of that method is proposed and the particular contribution of the ‘Copernican hypothesis’ to our knowledge of necessary truths is explained. It is argued that, though the necessity of the truths is in a way owing to the object's relation to our cognition, (...) the truths we come to know are fully objective, expressing necessary relations between properties. Kant's distinction between ‘phenomena’ and ‘noumena’ is shown to serve to properly restrict the scope of the necessity claims so that they do express necessary connections between properties.

In these few pages I shall try to demonstrate the emptiness of the most cumbersome piece of unexamined intellectual baggage at present being hauled about by English philosophers. I here cite one example to be going on with, at the end of the paper I shall give a handful more, and it would be easy to multiply the number by ten from the writings of reputable philosophers. The outstanding philosophical achievement of the ha1f-century which has just drawn to a close (...) [i.e. the period 1900-1950] has been an appreciation of the peculiar status of a priori judgments and of logically necessary or formally true propositions. . . . Though many problems remain unsolved, the main outline is now clear: formally true statements assert nothing about the world; instead, their function is to state principles according to which empirical propositions are deduced from other empirical propositions . . . (R. B. Braithwaite, ‘Moral Principles and Inductive Policies’, Proceedings of the British Academy 1950). What is wrong with this passage and with the myth of which it is an expression is its assumption that we have clear notions of what it is for a proposition to be logically necessary and of what it is for a proposition to assert something about the world, these notions being such that it is plausible to say that it has recently been discovered that every proposition having the first of these properties lacks the second. This assumption is wrong: there is no body of published theory giving a clear account of such notions, and despite fairly diligent searching I have so far failed to find, among the many philosophers who accept the myth, one who is able when challenged to supplement the literature on this vital point. Let me make it clear at once that I am not going to defend synthetic a priori truths - I am going to attack a popular mishandling of the truth that all necessary truths are analytic, and through this attack to draw right-wing conclusions from left-wing premisses..

It is argued that mathematical statements are "a posteriori synthetic" statements of a very special sort, To be called "structure-Analytic" statements. They follow logically from the axioms defining the mathematical structure they are describing--Provided that these axioms are "consistent". Yet, Consistency of these axioms is an empirical claim: it may be "empirically verifiable" by existence of a finite model, Or may have the nature of an "empirically falsifiable hypothesis" that no contradiction can be derived from the axioms.

This paper concerns the three great modal dichotomies: (i) the necessary/contingent dichotomy; (ii) the a priori/empirical dichotomy; and (iii) the analytic/synthetic dichotomy. These can be combined to produce a tri-dichotomy of eight modal categories. The question as to which of the eight categories house statements and which do not is a pivotal battleground in the history of analytic philosophy, with key protagonists including Descartes, Hume, Kant, Kripke, Putnam and Kaplan. All parties to the debate have accepted that some categories (...) are void. This paper defends the contrary view that all eight categories house statements—a position I dub ‘octopropositionalism’. Examples of statements belonging to all eight categories are given. (shrink)

The widespread assumption among academic philosophers that no truth can be simultaneously necessary and factual, founded on the analytic-synthetic dichotomy, was challenged from outside the profession by Ayn Rand and Leonard Peikoff in the 1960s, and from within the profession by Saul Kripke and Hilary Putnam in the 1970s. Gregory M. Browne's book Necessary Factual Truth represents a long-overdue attempt to synthesize the Rand-Peikoff and Kripke-Putnam approaches into an integrated theory. While Browne's project is partially successful, it gives up (...) one of the chief attractions of these approaches: the ability to preserve continuity of reference across radical theoretical change.

Our world seems fine tuned in life-permitting ways. If the cosmos contains many universes, only the appropriately tuned ones can be seen by living beings. An alternative is that God acted as Fine Tuner. We might account for God in terms of an eternally powerful ethical requirement that God exists, rejecting J. L. Mackie's judgment that absolute ethical requirements are incredibly queer. Mackie viewed such requirements as logically possible, so if they were absent then this would seem a matter of (...) synthetic necessity. Again, if they existed then their creative effectiveness would, Mackie thought, be logically possible. Their actual ineffectiveness would thus involve a further synthetic necessity. Theists could maintain that the synthetic necessities were instead ones making ethical requirements real and creatively powerful. Yet why, then, would there exist anything but divine knowledge of everything worth knowing? A spinozistic answer is that such knowledge is all that exists. (shrink)

My target in this paper is a view that has sometimes been called the ‘ Linguistic Doctrine of Necessary Truth ’ and sometimes ‘Conventionalism about Necessity’. It is the view that necessity is grounded in the meanings of our expressions—meanings which are sometimes identified with the conventions governing those expressions—and that our knowledge of that necessity is based on our knowledge of those meanings or conventions. In its simplest form the view states that a truth, if it (...) is necessary, is necessary because it is analytic. It is widely recognized that this simple version of the view faces a prima facie problem with the existence of the necessary a posteriori. Assuming that all analytic truths are a priori, if there are necessary a posteriori truths then there are necessary synthetic truths—contradicting the view’s claim that all necessary truths are analytic. Contemporary L-DONTers have things to say about the problem, but in this paper I want to suggest that there is a different, more serious, problem which arises from the phenomenon of indexicality, which L-DONTers have not taken account of. Though there are many versions of the problem, a simple one is this. Consider Kaplan’s celebrated sentence. (shrink)

C.D. Broad’s Reflections stands out as one of the few serious examinations of Moral Sense Theory in twentieth century analytic philosophy. It also constitutes an excellent discussion of the interconnections that allegedly exist between questions concerning what Broad calls the ‘logical analysis’ of moral judgments and questions about their epistemology. In this paper I make three points concerning the interconnectedness of the analytical and epistemological elements of versions of Moral Sense Theory. First, I make a general point about Broad’s association (...) between the Naïve Realist Moral Sense Theory (an epistemological view) and Objectivist Moral Sense Theory (a ‘logical analysis’). Second, I raise doubts about one of Broad’s arguments that Trans-Subjectivist Moral Sense Theory (logical analysis) can account for the apparent synthetic necessity of general moral propositions (epistemological). Third, I briefly discuss a view about logical analysis that should be of interest to contemporary Moral Sense Theorists – Neo-Sentimentalism – and respond to an argument whose conclusion is that this analysis is incompatible with a particular kind of epistemological view.

This paper argues that there are true synthetic modal claims and that modal questions in philosophy in general are to be interpreted not in terms of logical necessity but in terms of synthetic necessity. I begin by sketching the debate about modality between logical positivism and phenomenology. Logical empiricism taught us to equate being tautological with being necessary. The common view is that tautologies are necessary in the narrow sense but that there is also necessity (...) in a wider sense. I argue against this that we should distinguish necessity from analyticity and possibility from consistency. (shrink)

The problem of synthetic judgments touches upon the question whether philosophy is in fact capable of making independent truth statements. According to Kant, synthetic judgments formulate the conditions for the possibility of objectively valid knowledge a priori. As far as empirical attempts at reinterpretation of the aprioristic fall short of this ambition, Kant’s a priori goes deeper. This is because modern science strives towards objective knowledge, although its statements are fundamentally fallible. The topic of synthetic a priori (...) thus continues to be relevant. -/- This paper will show that, in order to be viable at all, a modernized version of transcendental philosophy must ‘depart from’ the concepts of “independence from empirics” and/or the “purity” of the aprioristic. Kant’s reflections on non-pure synthetic a priori knowledge already contain attempts at this. Furthermore, the aprioristic validity of knowledge does not exclude the possibility, that it can be discovered empirically. Fries and, subsequently, Nelson proceeded with this separation (initially ascribed to Reichenbach) between the contexts of validity and discovery of knowledge, pointing out that the a priori can indeed be discovered empirically, yet never be proven. -/- Currently, there are still a number of valid reasons for arguing that concepts from transcendental philosophy continue to be of fundamental importance for the modern sciences. However, it must not be neglected that, even within a modernized framework of transcendental philosophy various unsolved problems remain and/or are created (such as the unfeasibility of the aprioristic claim to general validity and necessity, the problem of drawing a clear boundary between the noumenal and phenomenal worlds). Moreover, the “beautiful structure” of the Kantian system, which constitutes much of its persuasive strength, is lost. (shrink)

n his famous book Le hasard et la ne ́cessite ́ (1970), Monod claims that natural evolution is based on the interplay between chance and necessity bringing about adaptive evolutionary change.

What are the implications of his conception about the issue of the deterministic or indeterministic nature (...) of the biological world? Is Monod’s view of what chance is relevant in contemporary biology? This paper, structured by these four questions, aims at providing a synthetic study of the way Monod conceptualizes chance, particularly highlighting the metaphysical and epistemological implications of his conception and its value in biology today.

The concept of necessity plays a central role in Kant's philosophy, but seems to lead to severe paradoxes. On the one hand he states: ‘Notwendigkeit und strenge Allgemeinheit sind sichere Kennzeichen einer Erkenntnis a priori’. On the other hand he talks also about ‘notwendig (d. i. nach einer Regel)’, which means ‘necessary according to the empirical natural laws’. However, he never states explicitly the distinction between these two different concepts of necessity. Either Kant's philosophy is inconsistent or we (...) have to assume that he indeed interchanges two different concepts, even if he does not tell us that there is a difference between synthetic apriori necessity and natural necessity. This paper defends the hypothesis of two different necessities and then shows how this strategy makes possible a rational reconstruction of Kant's epistemology. (shrink)

Chapter 1 WHY SYSTEMS PHILOSOPHY? Some reasons, for synthetic philosophy generally The persistent theme of this study is the timeliness and the necessity of ...

In this paper I aim to show that a certain law of nature, namely that common salt (sodium chloride) dissolves in water, is metaphysically necessary. The importance of this result is that it conflicts with a widely shared intuition that the laws of nature (most if not all) are contingent. There have been debates over whether some laws, such as Newton’s second law, might be definitional of their key terms and hence necessary. But the law that salt dissolves in water (...) is not that kind of law. The law statement ‘salt dissolves in water’ is clearly synthetic. It appears a classic case of a contingent law. We like to believe that there are possible worlds in which the laws of nature are different and in which salt does not dissolve in water. (shrink)

I argue that philosophy is like science in three interesting and non-obvious ways. First, the claims made by philosophy are synthetic, not analytic: philosophical claims, just like scientific claims, are not guaranteed by the structure of the concepts they involve. Second, philosophical knowledge is a posteriori, not a priori: the claims established by philosophers depend on the same kind of empirical support as scientific theories. And finally, the central questions of philosophy concern actuality rather than necessity: philosophy is (...) primarily aimed at understanding the actual world studied by science, not some further realm of metaphysical modality.

In a lot of domains in metaphysics the tacit assumption has been that whichever metaphysical principles turn out to be true, these will be necessarily true. Let us call necessitarianism about some domain the thesis that the right metaphysics of that domain is necessary. Necessitarianism has flourished. In the philosophy of maths we find it held that if mathematical objects exist, then they do of necessity. Mathematical Platonists affirm the necessary existence of mathematical objects (see for instance Hale and (...) Wright 1992 and 1994; Wright 1983 and 1988; Schiffer 1996; Resnik 1997; Shapiro 1997 and Zalta 1988) while mathematical nominalists, usually in the form of fictionalists, hold that necessarily such objects fail to exist (see for instance Balaguer 1996 and 1998; Rosen 2001 and Yablo 2005). In metaphysics more generally, until recently it was more or less assumed that whatever the right account of composition—the account of under what conditions some xs compose a y—that account will be necessarily true (for a discussion of theories of composition see Simons 1987 and van Inwagen 1987 and 1990; the modal status of the composition relation is explicitly addressed in Schaffer 2007; Parsons 2006 and Cameron 2007). Similarly, it has generally been assumed that whatever the right account is of the nature of properties, whether they be universals, tropes, or whether nominalism is true, that account will be necessarily true (though see Rosen 2006 for a recent suggestion to the contrary). In considering theories of persistence it has been widely held that whether objects endure or perdure through time is a matter of necessity (Sider 2001; though see Lewis 1999 p227 who defends contingent perdurantism). And with respect to theories of time it is frequently held that whichever of the A- or B-theory is true is necessarily true. A-theorists often argue that there is time in a world only if the A-theory is true at that world (see for instance McTaggart 1903; Markosian 2004; Bigelow 1996; Craig 2001) while B-theorists often argue that the A-theory is internally inconsistent (Smart 1987; Mellor 1998; Savitt 2000 and Le Poidevin 1991). Once again, we find a few recent contingentist dissenters. Bourne (2006) suggests that it is a contingent feature of time that it is tensed, and thus that the A-theory is contingently true. Worlds in which there exist only B-theoretic properties are worlds with time, it is just that time in those worlds time is radically different to the way it is actually. Other defenders of the B-theory, though not expressly contingentists, do offer arguments against versions of the A-theory that try to show that such A-theories theories are inconsistent with the actual laws of nature (see for instance Saunders 2002 and Callender 2000); these arguments, at least, leave room for the possibility that the A-theories in question are contingently false (at least on the assumption that the laws of nature are themselves contingent, an assumption that not everyone accepts). Despite some notable exceptions, necessitarianism has flourished in many, if not most, domains in metaphysics. One such exception is Lewis’ famous defence of Humean supervenience as a contingent claim about our world. Lewis does not argue that necessarily, the supervenience base for all matters of fact in a world is nothing but a vast mosaic of local matters of particular fact. Rather, he thinks that we have reason to think that our world is one in which Humean supervenience holds (see Lewis 1986 p9-10 and 1994). Another exception to the necessitarian orthodoxy is to be found in the lively debate about the modal status of the laws of nature. Here, if anything, contingentism has been the dominating force, with it generally being held that there are possible worlds in which different laws of nature hold (this view is defended by, among others, Lewis 1986 and 2010; Schaffer 2005 and Sidelle 2002). Necessitarian dissenters hold that the laws of nature are necessary, frequently because they think it is necessary that fundamental properties have the causal or nomic profiles they do (see for instance Shoemaker 1980 and 1988; Swoyer 1982; Bird 1995; Ellis and Lierse 1994). Nevertheless, when it comes to thinking about the nature of the laws themselves, the necessitarian presumption is back on firm footing. Though there is disagreement about whether the laws are generalisations that feature in the most virtuous true axiomatisation of all the particular matters of fact (often known as the Humean view of laws and defended by Ramsey 1978; Lewis 1986 and Beebee 2000) or whether laws are relations of necessity that hold between universals (a view defended by Armstrong 1983; Dretske 1977; Tooley 1977 and Carroll 1990) no one has seriously suggested that it might be a contingent matter which of these is the right account of laws. The necessitarian orthodoxy is not surprising since metaphysics is largely an a priori process. While a priori reasoning may be used to determine whether a proposition is necessary or contingent, it is not well placed (in the absence of a posteriori evidence) to determine whether a contingent proposition is actually true or false. Since metaphysicians aim to tell us which principles are true in which worlds, on the face of it the discovery that metaphysical principles are contingent seems to make part of the task of metaphysics epistemically intractable. In what follows I consider two reasons one might end up embracing contingentism and whether this would lead one into epistemic difficulty. The following section considers a route to contingent metaphysical truths that proceeds via a combination of conceptual necessities and empirical discoveries. Section 3 considers whether there might be synthetic contingent metaphysical truths, and the final section raises the question of whether if there were such truths we would be well placed to come to know them.

This book addresses central issues in the philosophy and metaphysics of science, namely the nature of scientific theories, their partial truth, and the necessity of scientific laws within a moderate realist and empiricist perspective. Accordingly, good arguments in favour of the existence of unobservable entities postulated by our best theories, such as electrons, must be inductively grounded on perceptual experience and not their explanatory power as most defenders of scientific realism claim. Similarly, belief in the reality of dispositions such (...) as causal powers which ground the natural necessity of scientific laws must be based on experience. Hence, this book offers a synthetic presentation of an original metaphysics of science, namely a metaphysics of properties, both categorical and dispositional, while at the same time opposing strong versions of necessitarism according to which laws are true in all possible worlds. The main theses and arguments are clearly presented in a non-technical way. Thus, on top of being of interest to the specialists of the topics discussed, it is also useful as a textbook in courses for third year and more advanced university students. (shrink)

W. V. Quine famously argues that though all knowledge is empirical, mathematics is entrenched relative to physics and the special sciences. Further, entrenchment accounts for the necessity of mathematics relative to these other disciplines. Michael Friedman challenges Quine’s view by appealing to historicism, the thesis that the nature of science is illuminated by taking into account its historical development. Friedman argues on historicist grounds that mathematical claims serve as principles constitutive of languages within which empirical claims in physics and (...) the special sciences can be formulated and tested, where these mathematical claims are themselves not empirical but conventional. For Friedman, their conventional, constitutive status accounts for the necessity of mathematics relative to these other disciplines. Here I evaluate Friedman’s challenge to Quine and Quine’s likely response. I then show that though we have reason to find Friedman’s challenge successful, his positive project requires further development before we can endorse it. (shrink)

Since the publication of Husserl's Logische Untersuchungen at the outset of this century, the notion of phenomenology has had a long and important history on the European continent. Of the many claims made on its behalf perhaps the most interesting is that phenomenology is able to ground philosophical assertions in a manner which is neither purely formal nor purely empirical, i.e., that phenomenology as a method is capable of transcending this very distinction. For example, phenomenologists argue that their reduction of (...) essences provides a way of knowing which is neither analytic nor synthetic but both. Having reached such an eidetic intuition phenomenologists claim to have attained a non-trivial universality and necessity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Paradox of Subjectivity: The Self in the Transcendental TraditionJeffrey EdwardsDavid Carr. The Paradox of Subjectivity: The Self in the Transcendental Tradition. New York/Oxford: Oxford University Press, 1999. Pp. xii + 150. Cloth, $35.00.This book presents a response to contemporary attacks on the concept of the subject. Carr investigates the historical background to the criticisms of the "Metaphysics of the Subject" that are found in French post-structuralist thought (...) and in critical theories descended from the Frankfurt School. In explaining this background, he targets the widely held assumption that the history of modern philosophy can best be understood in terms of a fundamentally unified conception of the subject and subjectivity that unfolds inevitably from Descartes and culminates in twentieth-century phenomenology and existentialism. Those who share this assumption fail to recognize the significance of what Husserl (in the Crisis of European Sciences) called the "paradox of subjectivity," which derives from the necessity of understanding the knowing subject both as a subject for the world and as an object in the world.The origins of contemporary interpretations of the metaphysics of the subject are found primarily in Heidegger's thought. Carr thus devotes the first chapter of this study to the critical assessment of Heidegger's view of modern metaphysics starting with Descartes. For Heidegger, Descartes took over the dominant concept of substance from traditional ontology and transferred it to the human subject. The Cartesian subject, then, was revealed as an underlying hypokeimenon that absorbs or overpowers the world by reducing it to the representational contents of the thinking thing. Moreover, Heidegger maintained that modern thinkers did not go beyond the reductive conception of subjectivity intrinsic to the Cartesian metaphysics of substance. This Heideggerian judgment applies to the major modern thinkers. Even Kant and Husserl figure as representatives of a tradition in which "the knowing subject takes the role of substance; everything is reduced to first properties, whether as immanent in consciousness, object for the subject, or, as in transcendental philosophy, construct and product of subjective activity" (Carr, 31).In chapters 2-4, Carr argues that the Heideggerian interpretation is inadequate with respect to Kant and Husserl. In supporting this position, Carr emphasizes the close affinities between Kant's and Husserl's conceptions of objectivity for consciousness and between their portrayals of subject and self. Specifically, Carr argues (1) that both thinkers were committed to the representationalist view of cognition that is typical of other major modern philosophers; and (2) that both presented parallel, and indeed unifiable, accounts of the relationship between the transcendental and the empirical self.The key to explaining the fundamental agreement between Kant's and Husserl's transcendental theories lies in the concept of intentionality. There are, of course, significant differences between Husserl's phenomenological method and the procedure of inquiry into the possibility conditions of objective experience that Kant follows in the Critique of Pure Reason. Still, Husserl's portrayal of the intentional character of consciousness provides the basis for understanding how Kant's account of transcendental apperception and the original synthetic unity of self-consciousness grounds a non-representationalist theory of the subject's relation to a world of objects. Husserl's portrayal of intentionality also enables us to see how Kant's concept of transcendental [End Page 609] apperception allows for a description of the empirical self as something that is part of the objective world. Conversely, the Kantian distinction between the transcendental and the empirical self, or subject, sheds light on the sense of the distinction that Husserl draws between transcendental and natural reflection. In natural reflection, I "appear to myself as an empirical subject within a world to which I relate in causal-bodily and intentional [i.e., purposive]-motivational ways" (89). On the other hand, the consciousness of self at issue in transcendental reflection involves my awareness of the meaning-constituting cognitive accomplishments by which I am consciousness of the world as the horizon of possible objects and, at the same time, as something transcendent to consciousness.It is Husserl's conception of intentionality, combined with Kant's understanding of the transcendental-empirical distinction, that allows us to grasp the full significance of the paradox...

Suárez’s primary attempt to rethink angelology can be found in the De Angelis. This work is a mighty commentary on the prima pars of Aquinas’ Summa Theologiae (qq. 50-64) which Suárez left to his colleagues after his years in Coimbra (1597-1607), and which was published posthumously in Lyon in 1620. The composition of the text is somewhat stratified and it includes many references to the Disputationes Metaphysicae, but Suárez most likely already started writing it during his years of teaching in (...) Spain and Italy (1575-1597), before 1597. Because of its Thomistic inspiration, the De angelis is a fundamentally theological and doctrinal work, the metaphysical core of which is independently treated in the DM 35, entitled De immateriali substantia creata. In this passage, which is eminently theoretical, Suárez grapples with the most important quaestiones concerning angels under a metaphysical point of view, therein offering one of the most interesting overviews of early modern angelology. In this paper, I will refer especially to the DM 35, a more synthetic and peculiar work, with some reference to De Angelis as well. I will focus especially on sections 1-3 of DM 35, and try to reconstruct Suárez’s views on the following points: a) the cosmological necessity of angels, their rational demonstrability and the possibility of man’s knowing them (sections 1-2); b) the immaterial essence of angels (section 3).

In lieu of an abstract, here is a brief excerpt of the content:48 SOME CQUHSEL ON HUMEAN RELATIONS In a paper published eight years ago I tried to bring out a neglected feature of Hume's theory of relations, namely the difference between philosophical and natural re1 2. lations. Now Ijnlay, without referring to my work, has expanded some of its themes in an extremely interesting and, I think, important way. At least he has made me rethink the whole distinction between (...) philosophical and natural relations and, what goes with relation theory, Hume's analytic-synthetic distinction. The strengths of his paper are, embarrassingly, the weaknesses of my own. I did not articulate clearly the connection between relation theory in Hume and the analytic-synthetic distinction. I shall turn to these strengths presently. My focus in this paper, however, will be on a central weakness in Imlay 's; and the point, it turns out, is one I gave full credence to earlier. Imlay does not distinguish what in Hume can and must be distinguished if we are to make any sense (let alone full sense) of his theory of causation. The distinction is be3 tweer, necessity and certainty. In trying to explicate Hume's distinction between intuitive and demonstrative inference on the one hand, and probability on the other, Imlay finally reaches an impasse. For, if the absence of the corresponding impression does not deprive mathematical necessity of... existence, why should it do so in the case of causal necessity? This, as Imlay recognizes, is at least related to standard criticisms of Hume, most forcibly articulated by Prichard. Imlay fortunately does not recommend—as Prichard does — throwing out the baby with the bath. If I understand him correctly, what he advocates is that we simply admit that Hume's attempts to ground necessity are inadequate. Before proceeding to details, let me issue two brief caveats. 49 First. It is of course not surprising that Hume fails to make a clear analytic-synthetic distinction. Has anyone? Lacking the logical tools of a Russell, or the mathematical understanding of a Leibniz, Hume labors under insuperable difficulties which, in many instances, are selfcreated. He is not clear as to whether necessity attaches to 'objects' or ideas (let alone sentences or propositions); he confuses, by invoking pseudo-psychological criteria involving conceivability, analytic with synthetic a priori truths; he has what many, including myself, consider to be a ludicrous theory about mathematics and mathematical objects. With these horrors to work with it is small wonder that necessity never gets grounded. Indeed, it is miraculous that the discussion even gets off the ground. But, Prichard's sneeringly just comments notwithstanding, both he and Imlay miss something, and I hope to show precisely what that is. Second. Hume is notoriously obscure in his discussion of what we would call ordinary physical objects. Sometimes (when he is in a psychologist or even ordinaryperson mood) he speaks as if physical objects cause impressions. Sometimes (when in the philosopher's closet) he speaks as if it makes no sense to speak of anything but impressions and collections of them, ordinary physical objects being relegated to the fictions of the vulgar. His theory of relations rather obviously suffers from the same disease; it is not clear what the relata are. Are impressions related temporally? Spatially? Is it relations between objects 'out there' of which he speaks when he discusses causation? Imlay is quite aware of the confusion ; he just lets it go. For now, I shall more or less follow suit. Later, as we shall see, one's choice makes a difference. In the long run, I think any coherent view of Hume will have to treat his analysis of physical objects in a way similar to Berkeley's · I. Hume, Prichard, and Imlay At first glance it would seem easy to allay at least Prichard' s fears. What, after all, is the connection between Hume's theory of relations, his attempt at distinguishing the necessary from the probable or possible, and his theory of causation? Hume claims that causation is a relation that, unlike some others, eg., resemblance, cannot be 'seen' to hold between its relata. But all of us believe that causal connections are necessary. Why do we all believe what... (shrink)

This paper offers a nuanced interpretation of Kant’s conception of the a priori, particularly in the context of constitutive principles. Contrary to the received view that separates necessity/universality from constitutivity—a distinction Kant allegedly failed to make—I propose a dual interpretation of the a priori that reconciles these aspects. This interpretation differentiates between a priori as ground (a priori-g) and as knowledge (a priori-k). The a priori-g, rooted in our mind’s invariant structure, encompasses pure intuitions, concepts, and apperception, underpinning all (...) knowledge and embodying constitutivity. Conversely, the a priori-k, deriving its necessity and universality from the a priori-g, is explained by the immutable subjective constitution. This paper argues that Kant implicitly prefigured Reichenbach’s distinction between necessity/universality and constitutivity, viewing their interconnectedness as justifying an extension of the former “marks” to all apriority. My analysis focused less on the synthetic a priori or the synthetic method and more on the constitutive, transcendental dimension of apriority, revealing Kant’s reasoning within the systematic context of the first Critique. It makes explicit Kant’s multiple notions of experience and a priori and his interconnected reasons for them—something that tends to be passed over in contemporary literature on constitutive a priori principles.

In this article, I shall argue that AI’s likely developments and possible challenges are best understood if we interpret AI not as a marriage between some biological-like intelligence and engineered artefacts, but as a divorce between agency and intelligence, that is, the ability to solve problems successfully and the necessity of being intelligent in doing so. I shall then look at five developments: (1) the growing shift from logic to statistics, (2) the progressive adaptation of the environment to AI (...) rather than of AI to the environment, (3) the increasing translation of difficult problems into complex problems, (4) the tension between regulative and constitutive rules underpinning areas of AI application, and (5) the push for synthetic data.

According to Kant our cognitive capacities result from synthetic functions _a priori, forming a complete and invariable system implemented into the human mind. From a Darwinian perspective such capacities are to be understood as genetic traits favored by selection, thus they are the variable components of contingent systems only. Kant intermingles two kinds of apriority: (1) Apriority as a result of inborn traits--judgments on this ground have only probability, not necessity; (2) Apriority as a result of the intentional (...) construction of closed systems--judgments on this ground have necessity, but they are not universal constituents of the human mind.

The student of Spinoza is faced by a peculiar difficulty. On opening the Ethics —Spinoza's chief work, completed for publication shortly before his death in 1674—he finds a system of metaphysics set forth in geometrical form, starting from definitions, axioms, and postulates, and advancing synthetically from first principles to a detailed interpretation of the universe. The difficulty lies not in the language— Spinoza's Latin is easy to construe, and there are translations—nor in the lack of literary graces; his style indeed (...) is singularly impressive in its austere dignity. It lies rather in this, that the method of exposition conveys a misleading suggestion of dogmatism and finality, and conceals almost all traces of the patient inquiries that issued in the finished structure. If once the principles of the system are admitted, the rest appears to follow by logical necessity. But by what processes of thought was Spinoza led to those principles? This is the problem that besets the reader: in order to understand the Ethics, he must penetrate behind the text of the propositions to their significance as answers to the questions that were stirring in Spinoza's mind.

The purpose of this essay is to identify the theological comprehension of the Word as Creator in the action of the Trinity, which Thierry of Chartres offers in his Tractatus de sex dierum operibus. In his brief and synthetic explanation, he makes coincide the findings of human reason with biblical notions, such as Figure and splendor, Wisdom, Truth, Word, not as a mere sequence but in their deep and relational meaning. Thierry’s rational method is deductive-mathematical, whereas the philosophical premise (...) is the rerum universitas articulated in levels of necessity and possibility. All this allows creation to be considered as explication of the complicatio—or multiplicity produced by unity— which is typical of the chartrian neoplatonism, with the characteristic seal of Thierry.

This thesis attempts to argue against an influential interpretation of Kant's philosophy of mathematics according to which the role of pure intuition is primarily logical. Kant's appeal to pure intuition, and consequently his belief in the synthetic character of mathematics, is, on this view, a result of the limitations of the logical resources available in his time. In contrast to this, a reading is presented of the development of Kant's philosophy of mathematics which emphasises a much richer philosophical role (...) for intuition, beyond that of filling in deductive gaps in mathematical arguments. This role is largely determined by two factors: on the one hand, the epistemological gap in a traditional account of mathematical certainty, and on the other hand, the metaphysical worry raised by the followers of Leibniz and Wolff regarding the status of mathematics as a science consisting of truths. ;By appreciating how Kant's philosophy of mathematics developed against the background of what he saw as a conflict between the 'metaphysicians' and the 'mathematicians', we can see how the doctrine of pure intuition was required to fill the gaps in the account of the method and certainty of mathematics which Kant presents in the Prize Essay of 1764. This conflict takes its sharpest form between the monadists who uphold the metaphysical necessity of simple elements, and the geometers who uphold the infinite divisibility of space. In the Prize Essay Kant indirectly addresses this conflict by comparing the two disciplines. He asserts that the method of attaining certainty in mathematics is different from the method of metaphysics, and that as a result of this difference--primarily the different roles of definitions in each--mathematics is capable of a higher degree of certainty than metaphysics. He does not, however, explain this difference. Such an explanation seems particularly important in light of Kant's wish to secure geometry against the challenge of metaphysics. This thesis attempts to show that it is to provide such an explanation, to provide a philosophical grounding for the Prize Essay account, that Kant invokes the doctrine of pure intuition in his later account of mathematical knowledge.

It would be ever so nice if there were a viable analytic/synthetic distinction. Though nobody knows for sure, there would seem to be several major philosophical projects that having one would advance. For example: analytic sentences2 are supposed to have their truth values solely in virtue of the meanings (together with the syntactic arrangement) of their constituents; i.e., their truth values are supposed to supervene on their linguistic properties alone.3 So they are true in every possible world where they (...) mean what they mean here.4 So they are necessarily true. So if there were a viable analytic/synthetic distinction (‘a/s distinction’ often hereafter), we would understand the necessity of at least some necessary truths. If, in particular, it were to turn out that the logical and/or the mathematical truths are analytic, we would understand why they are necessary. It would be ever so nice to understand why the logical and/or mathematical truths are necessary (cf. Gibson 1998; Quine 1998). (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.2 (2003) 271-272 [Access article in PDF] Lenn E. Goodman. Jewish and Islamic Philosophy: Crosspollinations in the Classic Age. New Brunswick, NJ: Rutgers University Press, 1999. Pp. xv + 256. Cloth, $55.00. This book is a bold if not audacious survey of select themes in Jewish and Islamic philosophy. The "crosspollinations" to which the subtitle refers carry the author back to classical Greece, (...) and forward to Spinoza, Kant, Bergson, Darwin, and beyond. Medieval Jewish and Islamic philosophers are placed as the centerpieces of a humanistic tradition rooted in the past and still resonating in the present.This is a view of medieval philosophy to which many a medievalist would like to subscribe, but which few would dare describe with such brio and eloquent assurance as Lenn Goodman, who is both a historian of philosophy and a philosopher. This confidence waylays Goodman, though, in that he regularly substitutes pronouncements for patient explanation and argument. The reader who is not already familiar with the issues discussed and positions advanced will have a hard time following him. More informed readers may well question many of his summary judgments and piquant observations.The ideal reader of this work is one who has read Goodman's other studies, to which the notes frequently refer. The arguments adumbrated here are presumably laid out in detail in these earlier essays and books. The text before us is thus for the most part more a statement of faith, the author's summary credo, than a reasoned exposition of Jewish and Islamic philosophy. To Goodman, "the approach is synthetic rather than descriptive" (ix).The book deals with "issues of abiding philosophical interest: freedom and determinism, the nature and meaning of history, the basis of ethical values, the foundations and social implications of friendship, the viability and relevance of the idea of God." These admirable themes are pursued in separate yet complementing chapters that compare the tenth-century free-thinker and physician Muhammad ibn Zakariyâ al-Râzî and Epicurus; the tenth-century pietist Bahya ibn Paquda and Kant; and the fourteenth-century Maghribi historian Ibn Khaldûn and Thucydides. Three other chapters compare, respectively, Maimonides and such major Islamic philosophers as Avicenna, Al-Ghazâlî, and Ibn Bâjjah; Maimonides, Al-Ghazâlî, and the Persian ethicist Miskawayh (tenth/eleventh centuries); and Maimonides, Aristotle, and Spinoza.It is at once obvious that Maimonides (twelfth century) is at the heart of this work, reflecting Goodman's longstanding interest in this towering figure of medieval Jewish philosophy. Less obvious is Goodman's contention that Maimonides is to be seen not only in relation to Avicenna, Al-Ghazâlî, and Ibn Bâjjah, but also to Râzî, Bahya, and Miskawayh. Goodman has constructed a narrative of persons and ideas, abstracting from their contexts common concerns and purposes. While there is much to admire in these constructions—patently erudite and challenging as they are—the direct filiations Goodman assumes are often conjectural at best.Take, for example, Goodman's chapter on "Maimonides and the Philosophers of Islam," with its subtitles of "Creation" and "Theophany." These terms are shorthand for Maimonides' treatment of the science of physics and metaphysics, both in their normative and extraordinary appearances. Goodman correctly notes that Maimonides is deeply indebted to Muslim philosophers (and their Greek predecessors) for his knowledge of these fields, though he does stretch matters in singling out the importance of Al-Kindî and Râzî as influences upon Maimonides' thought.Goodman does this in part because he believes Maimonides shared, in varying degrees, a creationist position with them. Goodman accepts at face value Maimonides' assertion that only a creationist thesis allows for voluntarism, a (theologically) meaningful Divine Will. "Only voluntarism," Goodman asserts in the name of Maimonides, "can break the stranglehold of necessity, making emanation itself possible, allowing change, and crucially, allowing change in the natures of things, that is, evolution, as a means of bringing creation to 'maturity'"(98). This statement, besides its anachronistic introduction of evolution into medieval notions of change, misinterprets Maimonides' view... (shrink)

Moral properties would supervene upon non-moral properties and be conceptually autonomous. That, according to Simon Blackburn, would make them if not impossible at least mysterious, and evidence for them best explained by theorists who say they are not real. In fact moral properties would not challenge in ways Blackburn has contended. There is, however, something new that can be gathered from his arguments. What would the supervenience of moral properties and their conceptual autonomy from at least total non-moral properties entail (...) not only for Intuitionists, who ‘knew this all along,’ but for all moral realists, that there are synthetic necessary moral principles? There is for all moral realists the problem of explaining ‘what in the world’ makes possible these necessities. (shrink)
