Although the terms mentor and thesis advisor (or research supervisor) are often used interchangeably, the responsibilities associated with these roles are distinct, even when they overlap. Neither are role models necessarily mentors, though mentors are role models: good examples are necessary but not sufficient. Mentorship is both a personal and a professional relationship. It has the potential for raising a number of ethical concerns, including issues of accuracy and reliability of the information conveyed, access, stereotyping and tracking of (...) advisees, and the abuse of power. Nevertheless, mentors can be critically important for professional success and are one of a number of elements that affect the responsible conduct of research. In addition, the community as a whole has a responsibility to mentor junior members. (shrink)

Henry Sheffer’s 1908 Harvard Ph.D. thesis contains an interesting appendix on a central feature of the logical work of his thesis advisor, Josiah Royce. This is the claim in Royce’s 1905 article “The Relations of the Principles of Logic to the Foundations of Geometry” that an unsymmetric ordering relation can be defined on the single symmetric O-relation for which he gives postulates in that paper. Sheffer criticizes Royce’s specific definition from the point of view of the evolving (...) twentieth century conception of axiomatic method and also shows more generally that an unsymmetric1 order relation cannot be defined in the system of the 1905 paper based on the O-relation. In this article I wish to consider the nature.. (shrink)

Committee: Fred Dretske (Advisor), Michael Bratman, Debra Satz, Ken Taylor. My thesis is that testimonial knowledge of particular matters of fact is a species of perceptual (non-inferential) knowledge. There are two rival views. The first holds that testimonial knowledge is a species of inductive knowledge. According to inductivism, we learn from others because we have inductively established that testimony is a reliable source. I argue that this view is too demanding. The second holds that testimonial knowledge is, like (...) memory, preservative. According to preservativism, a hearer learns from a speaker because the speaker's knowledge is transferred to the hearer. Testimony preserves knowledge across subjects at a time as memory preserves knowledge within a subject over time. This view is subject to counter-example. What matters to whether the hearer teams is not whether the speaker knows, but whether the hearer's cognitive state of taking the speaker to state that P adequately grounds the belief that P. One way to account for "adequate grounds" is in terms of Information-carrying I argue that knowledge is not preserved or transferred through testimony, rather Information is conveyed. This shows that testimonial knowledge is perceptual knowledge, for perceptual knowledge depends on adequate grounds and not prior knowledge. Testimonial knowledge, like standard cases of perceptual knowledge, is original. Call my position originalism. ;There are three main sources of opposition. First, linguistic acceptance is inferential in a way that perceptual belief is not. Second, acceptance, if reliable, is reliable in a way that perceptual belief is not. Third, testimony involves agency, free will, and the following of norms and perceptual belief does not. In reply I argue that linguistic acceptance that the world is a certain way does not depend on believing that the speaker stated that it is that way, that even if there are differences between the way in which testimony is reliable and the way standard cases of perception are reliable, those differences are only contingent or epistemologically irrelevant, and that even though testimony does involve agency and norms in a way that vision, taste, and so on do not, that fact does not matter to whether testimonial knowledge is a species of perceptual (non-inferential) knowledge.

Much of scientific inference involves fitting numerical data with a curve, or functional relation. The received view is that the fittest curve is the curve which best balances the conflicting demands of simplicity and accuracy, where simplicity is measured by the number ofparameters in the curve. The problem with this view is that there is no commonly accepted justification for desiring simplicity. This paper presents a measure of the stability of equations. It is argued that the fittest curve is the (...) curve which best balances stability and accuracy. The received view is defended with a proof that simplicity corresponds to stability, for linear regression equations. 1This paper is based on part of my doctoral dissertation. My thanks go to my thesis supervisor Professor Alasdair Urquhart for his encouragement, constructive criticism, and for directing me to several relevant articles: to my advisor Professor Ian Hacking for reminding me to concentrate on results that might have some application in the real world; and to my friend Wendy Brandts for sharing her ideas on a closely related problem.

§0. Introduction. In [16], Barwise described his graduate study at Stanford. He told of his interactions with Kreisel and Scott, and said how he chose Feferman as his advisor. He began working on admissible fragments of infinitary logic after reading and giving seminar talks on two Ph.D. theses which had recently been completed: that of Lopez-Escobar, at Berkeley, on infinitary logic [46], and that of Platek [58], at Stanford, on admissible sets.Barwise's work on infinitary logic and admissible sets is (...) described in his thesis [4], the book [13], and papers [5]—[16]. We do not try to give a systematic review of these papers. Instead, our goal is to give a coherent introduction to infinitary logic and admissible sets. We describe results of Barwise, of course, because he did so much. In addition, we mention some more recent work, to indicate the current importance of Barwise's ideas. Many of the central results are stated without proof, but occasionally we sketch a proof, to indicate how the ideas fit together.Chapters 1 and 2 describe infinitary logic and admissible sets at the time Barwise began his work, circa 1965. From Chapter 3 on, we survey the developments that took place after Barwise appeared on the scene.§1. Background on infinitary logic. In this chapter, we describe the situation in infinitary logic at the time that Barwise began his work. We need some terminology. By a vocabulary, we mean a set L of constant symbols, and relation and operation symbols with finitely many argument places. As usual, by an L-structureM, we mean a universe set M with an interpretation for each symbol of L. (shrink)

The idea of rational understanding lays very close to the heart of Professor Janusz Kuczyński, an advocate of universalism as well as dialogue between diverse philosophical schools and worldviews, and doctoral advisor to the present paper’s author. This idea’s theoretical conceptualisation—a conceptualisation that has proven to be convincing and adequate to the conditions of the modern world—was developed by Professor Jürgen Habermas, whose ideas and theories were also the subject of a doctoral thesis written by this paper’s author (...) in the latter half of the 1970s under Professor Kuczyński’s tutelage. The author shares some grateful memories of his doctoral tutor, and also sets his one-time attempts to apply the theory of communicative action to two experiences of the real socialism era in Poland against his efforts to analyse contemporary Polish realities through the prism of the communicative rationality conception. This comparison shows that the application of a conception of rationality funded by communicative action to the turbulent transformations under real socialism was to a certain extent naïve—though not devoid of critical significance—and also reveals the preconditions for the implementation of the rules of communicative rationality in social and political reality.The paper is in part dedicated to the memory of Professor Kuczyński, therefore it contains a somewhat extensive account of the circumstances which led the author to study the thought of Habermas under Kuczyński’s tutelage, as well as the consequences of this choice, which proved of considerable significance for his further life. However, the main themes are, first, the validity of applying a conception of rationality funded by communicative action to two significant experiences of the real socialism era, and, secondly, the need—revealed by diagnosing contemporary Polish reality with the help of the communicative rationality conception—for certain preconditions enabling the implementation of this type of rationality in social and political reality. One such precondition is the transition of sufficiently broad parts of society from thinking in terms of worldviews to post-metaphysical thinking in terms of the “lifeworld”. (shrink)

The subject of this study is to examine the master's and doctoral theses in the field of Sociology of Religion, between 2005 and 2015 in Turkey and published in National Thesis Center of the Council of Higher Education, according to their subject, the main concept they deal with, their type, their advisor title, the year they were prepared and the university. This research can be described as a product of the search for a solution to the problem of (...) looking at the field holistically and quick and easy access to theses in the field of Sociology of Religion. Thanks to this research, the current status of the subject to be investigated in the field of Sociology of Religion will be seen more clearly; New and original works that are free from repetition will be enabled. Descriptive analysis was used to analyze the data. According to the results of this research, the majority of the studies conducted in the field of Sociology of Religion in Türkiye consist of master's theses. In the theses between 2005 and 2015, the concept of "religious life" (n=32) was mostly discussed. Later, research was conducted on the concepts of "woman" (n=23), "religious leaders" (n=21), "piety" (n=13) and "Alevism" (n=12).When the theoretical/empirical categorical distribution of theses is examined, 114 of the scientific studies at the master's level are theoretical sociology of religion research and 134 of them are empirical studies, whereas it was observed that there are more empirical studies in doctoral theses. When the distribution of theses was examined according to general subjects of Sociology of Religion, it was seen that more studies were conducted on "Social Structure and Institutions". (shrink)

Hugh Everett III died of a heart attack in July 1982 at the age of 51. Almost 26 years later, a New York Times obituary for his PhD advisor, John Wheeler, mentioned him and Richard Feynman as Wheeler’s most prominent students. Everett’s PhD thesis on the relative state formulation of quantum mechanics, later known as the “Many Worlds Interpretation”, was published (in its edited form) in 1957, and later (in its original, unedited form) in 1973, and since then (...) has given rise to one of the most radical schools of thought in the foundations of quantum theory. Several years ago two conferences held in Oxford and in the Perimeter Institute celebrated the occasion of 50 years to the first publication of Everett’s thesis. The book Many worlds? grew out from contributions to these conferences, but, as its editors emphasize, it is more than mere conference proceedings. Instead, an attempt was made to assemble an impressive collection of papers which together illustrate the promise of the many worlds interpretation and the obstacles it faces. 23 papers divided into six sections follow an introduction by Simon Saunders, one of Oxford’s fiercest Everettians. The first four sections cover two thorny issues that have been flagged by contemporary opponents to the many worlds interpretation, namely, the problem of ontology and the problem of probability, while the fifth discusses alternatives to Everett such as Bohmian mechanics and information–theoretic approaches to quantum theory. The sixth section seems to be a wild card, hosting several papers unrelated to each other, including one of the most interesting contributions to this volume on the history of Everett’s thesis and his (some may say all too) short academic career. Each section concludes with transcripts of the discussion session that took place after the talks, thus giving an additional emphasis to the points of contention. Apart from general comments on the volume, in what follows I would like to concentrate on few papers I found especially illuminating. Start with ontology.. (shrink)

"Dissertation Advisor: Richard Cobb-Stevens Second Reader: David Rasmussen -/- My overall concern is with the Kantian legacy in political thought. More specifically, I want to know if normative talk is still viable in the wake of Wittgenstein and the linguistic turn; and if so, in what form. Most commentators today believe we have to choose between these two thinkers, either sacrificing a real concern with normativity (“relativism”) or a convincing engagement with our ordinary language (“universalism”). I follow Hilary Putnam (...) in thinking we do not have to choose between these rather drastic construals. It might still be possible to defend the force and relevance of normative exchange while still being alive to the drift of ordinary communication. This middle stance is best exemplified, I believe, by what I have called normative evaluation. -/- Basically, I am building on and extending insights and styles of argumentation that Putnam has pioneered over the years. The universalist’s rigid dichotomies (norms vs. values, rules vs. attitudes, thick vs. thin ethical concepts, justice vs. the good life, etc.) all fail the test of ordinary language. As Putnam has also shown, however, we do rely on paired concepts like these and they might still be argued to be strong—rational—enough to justify making *relative distinctions*. A relative distinction between values and norms is decisive, I think, because it would put us in the position to talk meaningfully about and reasonable settle what is more proper to one particular individual, group, or society from what is less so, thereby also making possible a normative exchange *between* them. I am therefore taking Putnam as pointing out a way to preserve key Kantian insights about the irreducibility and ubiquity of the normative while discarding his transcendental wrapping, all the while avoiding the kind of slide to wholesale cultural relativism that so easily follows in the wake of standard critiques of Kant. -/- Chapter 1: General survey. Chapter 2: Historical background (Kant, Kierkegaard, Wittgenstein). Chapter 3: Basic language philosophical arguments. Chapter 4: Rejection of the quasi-transcendental model (Apel & Habermas).

This dissertation argues that the desire satisfaction theory, arguably the dominant theory of well-being at present, fails to explain why depression is bad for a person. People with clinical depression desire almost nothing, but the few desires they do have are almost all satisfied. So it appears the theory must say these people are relatively well-off. A number of possible responses on behalf of the theory are considered, and I argue that each response either fails outright, or requires modifications to (...) the desire satisfaction theory which make the theory unattractive for other reasons.

In this dissertation, I argue that vagueness is a metaphysical phenomenon---that properties and objects can be vague---and propose a trivalent theory of vagueness meant to account for the vagueness in the world. In the first half, I argue against the theories that preserve classical logic. These theories include epistemicism, contextualism, and semantic nihilism. My objections to these theories are independent of considerations of the possibility that vagueness is a metaphysical phenomenon. However, I also argue that these theories are not capable (...) of accommodating metaphysical vagueness. As I move into my positive theory, I first argue for the possibility of metaphysical vagueness and respond to objections that charge that the world cannot be vague. One of these objections is Gareth Evans' much-disputed argument that vague identities are impossible. I then describe what I call the logic of states of affairs. The logic of states of affairs has as its atomic elements states of affairs that can obtain, unobtain, or be indeterminate. Finally, I argue that the logic of states of affairs is a better choice for a theory of vagueness than other logics that could accommodate metaphysical vagueness such as supervaluationism and degree theories. Preference should be given to the logic of states of affairs because it provides a better explanation of higher-order vagueness and does a better job of matching our ordinary understandings of logical operators than supervaluationism does and because it provides a more general account of indeterminacy than the account given by degree theories.

This paper is concerned with the deployment and the transformation of Gramsci’s notion of hegemony and the purpose it serves. I argue that, in its travel from Rome to London, this notion acquired something like a truth-value. In London the notion yielded what I call ‘hegemony thinking’: a distinctive style of thinking that focused on strategy to carry out effective political interventions. To demonstrate my claim I trace the Marxism Today discussion on the crisis of the Left and strategy in (...) the UK. In particular, I look at the engagements of the late historian Eric Hobsbawm and the cultural theorist Stuart Hall with Gramsci’s work, and examine the appropriation of the coordinates of hegemony by the entrepreneur and Blair policy advisor Geoff Mulgan.

Two important thought-experiments are associated with the work of Hilary Putnam, one designed to establish multiple realizability for mental kinds, the other designed to establish essentialism for natural kinds. Comparing the thought-experiments with each other reveals that the scenarios in both are structurally analogous to each other, though his intuitions in both are greatly at variance, intuitions that have been simultaneously well received. The intuition in the former implies a thesis that prioritizes pre-scientific over scientific indicators for identifying mental (...) kinds in certain circumstances, while his intuition in the latter implies a converse thesis, prioritizing scientific over pre-scientific indicators for identifying natural kinds in analogous circumstances. In this paper I question whether we can consistently endorse both of these intuitions. A consideration is presented to attempt to justify the common intuition found in the multiple realization thought-experiment. Then it is argued that this same consideration has application in the structurally analogous Twin-Earth thought-experiment. This recommends a kind of multiple realization thesis for natural kinds, in opposition to a scientific essentialist approach. The various respects in which mental kinds like pain and natural kinds like water are similar to each other, such that similar philosophical treatments are warranted for both, are enumerated.

The Uniqueness Thesis holds, roughly speaking, that there is a unique rational response to any particular body of evidence. We first sketch some varieties of Uniqueness that appear in the literature. We then discuss some popular views that conflict with Uniqueness and others that require Uniqueness to be true. We then examine some arguments that have been presented in its favor and discuss why permissivists find them unconvincing. Last, we present some purported counterexamples that have been raised against Uniqueness (...) and discuss some possible reasons why proponents of Uniqueness might find these similarly unconvincing.

Could the employment of large language models (LLMs) in place of human advisors improve the problem-solving ability of democratic assemblies? LLMs represent the most significant recent incarnation of artificial intelligence and could change the future of democratic governance. This paper assesses their potential to serve as expert advisors to democratic representatives. While LLMs promise enhanced expertise availability and accessibility, they also present specific challenges. These include hallucinations, misalignment and value imposition. After weighing LLMs’ benefits and drawbacks against human advisors, I (...) argue that time-tested democratic procedures, such as deliberation and aggregation by voting, provide safeguards that are effective against human and machine advisor shortcomings alike. Additional protective measures may include custom training for advisor LLMs or boosting representatives’ competencies in query formulation. Implementation of adversarial proceedings in which LLM advisors would debate each other and provide dissenting opinions is likely to yield further epistemic benefits. Overall, promising interventions that would mitigate the LLM risks appear feasible. Machine advisors could thus empower human decision-makers to make more autonomous, higher-quality decisions. On this basis, I defend the hypothesis that LLMs’ careful integration into policymaking could augment democracy’s ability to address today’s complex social problems. (shrink)

The co-instantiation thesis is pivotal to a significant solution to the problem of causal exclusion. But this thesis has been subject to some powerful objections. In this paper, I argue that these difficulties arise because the thesis lacks the necessary metaphysical framework in which its claims should be interpreted and understood. Once this framework is in place, we see that the co-instantiation thesis can answer its critics. The result is a rehabilitated co-instantiation solution to the troubling (...) problem of causal exclusion. But questions remain concerning the viability of certain of its applications. (shrink)

There are currently serious concerns that published scientific findings often fail to be reproducible, and that some solutions may be gleaned by attending the several methodological and sociological recommendations that could be found in the literature. However, researchers would also arrive at some answers by considering the advice of the philosophy of science, particularly semantics, about theses on truth related to scientific realism. Sometimes scientists understand the correspondence thesis of truth as asserting that the next unique empirical confirmation of (...) a hypothesis suffices to attribute truth to it provisionally. Such empiricist bias is not necessarily at the core of CTT, but Mario Bunge proposed the synthetic thesis of truth, based on CTT, to explicitly avoid the bias. STT requires considering a hypothesis corroborated, both by purely empirical confirmation and external consistency or compatibility with the bulk of existing background knowledge. While a capricious understanding of CTT could be rigged to recommend the “one shot game” in hypothesis testing, STT clearly demands the use of multiple approaches, empirical as well as theoretical, and it asserts that a scientific test is effective to the extent to which it is neither purely empirical, nor viewed in isolation. Pattern consistency together with an understanding of causal relations make confirmed hypotheses robust and more reliable. The militancy of the double mechanism of hypothesis control of STT can help mitigate the reproducibility crisis. Earl Werner’s research program in community ecology is an example of the use of STT criteria, which leads to the development of reliable, cross-checked, ecological results, with high predictive capacity.

When faced with the charge that a given concept of God is contradictory, the standard move among philosophers and theologians has been to try to explain away the contradiction and show that the concept of God in question is consistent. This has to do, of course, with the Law of Non-Contradiction (LNC). Another option, which has recently generated interest among logicians and analytic philosophers of religion, is to reject such a move as unnecessary and defend what might be called the (...) contradictory God thesis. To be sure, something close to that can be found in philosophers such as Pseudo-Dionysius, Thomas Aquinas and Nicolaus de Cusa. However, it is only recently that this approach has gained momentum, certainly driven by the contemporary advance of dialetheism and glut theoretic approaches in general, and paraconsistent logic. Needless to say, a standard move among defenders of the contradictory God thesis is to challenge the LNC. The argumentation, however, is seldomly framed in conceptual terms. Instead, it is mostly framed in ontological terms, as God being a contradictory entity. From this perspective, the contradictory God thesis is the thesis that God is a contradictory object. My goal in this paper is to provide a conceptual assessment of the discussion surrounding the contradictory God thesis. To achieve this, I make use of a general and hopefully non-controversial meta-theory of concepts and adopt a semantic approach rather than a metaphysical one. Within this framework, I address the following questions: What are the different ways we can understand the contradictory God thesis? What grounds are there for rejecting a contradictory concept of God? What standard moves are available to defend oneself from such criticisms and how do they relate to the LNC? What challenges do they present? As a secondary goal, the paper introduces a novel defense of the contradictory God thesis, drawing on a specific interpretation of the theology of the 16th-century Indian thinker Jīva Gosvāmī, which avoids the need to challenge the LNC. I term this approach ‘non-dialetheic mystical contradictory theism.’. (shrink)

In this short paper we extend the dialectical triad thesis-antithesis-synthesis to the neutrosophic tetrad thesis-antithesis-neutrothesis-neutrosynthesis. We do this for better reflecting our world, since the neutralities between opposites play an important role. The neutrosophic synthesis (neutrosynthesis) is more refined that the dialectical synthesis. It carries on the unification and synthesis regarding the opposites and their neutrals too.

The Thesis of Kant’s Third Antinomy asserts that, because it is “necessary to assume another causality through freedom” in order to derive all the appearances of the world, “causality in accordance with the laws of nature is not the only one” (A444/B472). The argument Kant supplies in support of this, however, has been the subject of interpretative disagreement since at least Schopenhauer, with the most plausible reconstructions being dismissed as question-begging, resting on a conflation relating to the principle of (...) sufficient reason, or attacking a straw-man of the Antithesis position. In this paper, I attempt to provide a novel interpretation of the argument for the Thesis position, one that offers a more compelling case against a charitably interpreted Antithesis position.

This essay accounts for Mengzi’s 孟子 failure in persuading King Xuan of Qi (Qi Xuan Wang 齊宣王) to act morally. We argue that the distinction between internal and external reasons in contemporary philosophy helps to highlight the nature of the failure. The problem of nontransmission of the compassionate impulse within a person despite moral persuasion, which Mencians need to address in order to enhance the success of moral conversion, is now explained as a result of misdirecting the advisee to the (...) lofty ideal of sagehood. We conclude by proposing a proleptic understanding of external reasons within a pragmatic model of giving moral advice. (shrink)

The so-called ‘Adams’ Thesis’ is often understood as the claim that the assertibility of an indicative conditional equals the corresponding conditional probability—schematically: $${({\rm AT})}\qquad\qquad\quad As(A\rightarrow B)=P({B|A}),{\rm provided}\quad P(A)\neq 0.$$ The Thesis is taken by many to be a touchstone of any theorizing about indicative conditionals. Yet it is unclear exactly what the Thesis is . I suggest some precise statements of it. I then rebut a number of arguments that have been given in its favor. Finally, I (...) offer a new argument against it. I appeal to an old triviality result of mine against ‘Stalnaker’s Thesis’ that the probability of a conditional equals the corresponding conditional probability. I showed that for all finite-ranged probability functions, there are strictly more distinct values of conditional probabilities than there are distinct values of probabilities of conditionals, so they cannot all be paired up as Stalnaker’s Thesis promises. Conditional probabilities are too fine-grained to coincide with probabilities of conditionals across the board. If the assertibilities of conditionals are to coincide with conditional probabilities across the board, then assertibilities must be finer-grained than probabilities. I contend that this is implausible—it is surely the other way round. I generalize this argument to other interpretations of ‘ As ’, including ‘acceptability’ and ‘assentability’. I find it hard to see how any such figure of merit for conditionals can systematically align with the corresponding conditional probabilities. (shrink)

This case study examines the conflicts of interest that can arise in the selection of jury members to evaluate a PhD thesis, and the costs associated with trying to avoid COI.

In tradition linked to Aristotle and Kant, many contemporary philosophers treat practical and theoretical normativity as two genuinely distinct domains of normativity. In this paper I consider the question of what it is for normative domains to be distinct. I suggest that there are two different ways that the distinctness thesis might be understood and consider the different implications of the two different distinctness theses.

In this paper, I offer two counterexamples to the so-called ‘Uniqueness Thesis.’ As one of these examples rely on the thesis that it is possible for a justified belief to be based on an inconsistent body of evidence, I also offer reasons for this further thesis. On the assumption that doxastic justification entails propositional justification, the counterexamples seem to work.

In this paper I present a precise version of Stalnaker's thesis and show that it is both consistent and predicts our intuitive judgments about the probabilities of conditionals. The thesis states that someone whose total evidence is E should have the same credence in the proposition expressed by 'if A then B' in a context where E is salient as they have conditional credence in the proposition B expresses given the proposition A expresses in that context. The (...) class='Hi'>thesis is formalised rigorously and two models are provided that demonstrate that the new thesis is indeed tenable within a standard possible world semantics based on selection functions. Unlike the Stalnaker-Lewis semantics the selection functions cannot be understood in terms of similarity. A probabilistic account of selection is defended in its place. -/- I end the paper by suggesting that this approach overcomes some of the objections often leveled at accounts of indicatives based on the notion of similarity.

The Church-Turing thesis makes a bold claim about the theoretical limits to computation. It is based upon independent analyses of the general notion of an effective procedure proposed by Alan Turing and Alonzo Church in the 1930''s. As originally construed, the thesis applied only to the number theoretic functions; it amounted to the claim that there were no number theoretic functions which couldn''t be computed by a Turing machine but could be computed by means of some other kind (...) of effective procedure. Since that time, however, other interpretations of the thesis have appeared in the literature. In this paper I identify three domains of application which have been claimed for the thesis: (1) the number theoretic functions; (2) all functions; (3) mental and/or physical phenomena. Subsequently, I provide an analysis of our intuitive concept of a procedure which, unlike Turing''s, is based upon ordinary, everyday procedures such as recipes, directions and methods; I call them mundane procedures. I argue that mundane procedures can be said to be effective in the same sense in which Turing machine procedures can be said to be effective. I also argue that mundane procedures differ from Turing machine procedures in a fundamental way, viz., the former, but not the latter, generate causal processes. I apply my analysis to all three of the above mentioned interpretations of the Church-Turing thesis, arguing that the thesis is (i) clearly false under interpretation (3), (ii) false in at least some possible worlds (perhaps even in the actual world) under interpretation (2), and (iii) very much open to question under interpretation (1).

I spell out and update the individuality thesis, that species are individuals, and not classes, sets, or kinds. I offer three complementary presentations of this thesis. First, as a way of resolving an inconsistent triad about natural kinds; second, as a phylogenetic systematics theoretical perspective; and, finally, as a novel recursive account of an evolved character. These approaches do different sorts of work, serving different interests. Presenting them together produces a taxonomy of the debates over the thesis, (...) and isolates ways it has been productive. This goes to the larger point of this paper: a defense of the individuality thesis in terms of its utility, and an update of it in light of recent theoretical developments and empirical work in biology.

In this article, I explore the relationship between the supersession thesis and the rights of future people. In particular, I show that changes in circumstances might supersede future people’s rights. I argue that appropriating resources that belong to future people does not necessarily result in a duty to return the resources in full. I explore how these findings are relevant for climate change justice. Assuming future generations of developing countries originally had a right to use a certain amount of (...) the carbon budget, changing circumstances could result in rights-supersession. Consequently, members of future generations of industrialized countries may be allowed to use part of the share of the carbon budget belonging to developing countries. (shrink)

The paper has two goals. First, it defends one type of subjectivist account of reasons for actions—deliberative accounts—against the criticism that they commit the conditional fallacy. Second, it attempts to show that another type of subjectivist account of practical reasons that has been gaining popularity—ideal advisor accounts—are liable to commit a closely related error. Further, I argue that ideal advisor accounts can avoid the error only by accepting the fundamental theoretical motivation behind deliberative accounts. I conclude that ideal (...) advisor accounts represent neither a substantial departure from, nor a substantial improvement upon, deliberative accounts. (shrink)

We argue that traditional formulations of the reduction thesis that tie it to privileged relational operations do not suffice for Peirce’s justification of the categories and invite the charge of gerrymandering to make it come out as true. We then develop a more robust invariant formulation of the thesis, one that is immune to that charge, by explicating the use of triads in any relational operations. The explication also allows us to track how Thirdness enters the structure of (...) higher order relations and even to propose a numerical measure of it. Our analysis reveals new conceptual phenomena when negation or disjunction are used to compound relations. (shrink)

Church's thesis asserts that a number-theoretic function is intuitively computable if and only if it is recursive. A related thesis asserts that Turing's work yields a conceptual analysis of the intuitive notion of numerical computability. I endorse Church's thesis, but I argue against the related thesis. I argue that purported conceptual analyses based upon Turing's work involve a subtle but persistent circularity. Turing machines manipulate syntactic entities. To specify which number-theoretic function a Turing machine computes, we (...) must correlate these syntactic entities with numbers. I argue that, in providing this correlation, we must demand that the correlation itself be computable. Otherwise, the Turing machine will compute uncomputable functions. But if we presuppose the intuitive notion of a computable relation between syntactic entities and numbers, then our analysis of computability is circular. (shrink)
