This paper proposes to model legal reasoning asdialectical theory-constructiondirected by teleology. Precedents are viewed asevidence to be explained throughtheories. So, given a background of factors andvalues, the parties in a case canbuild their theories by using a set of operators,which are called theory constructors.The objective of each party is to provide theoriesthat both explain the evidence (theprecedents) and support the decision wished by thatparty. This leads to theory-basedargumentation, i.e., a dialectical exchange ofcompeting theories, which support opposedoutcomes by explaining the same (...) evidence and appealingto the same values. The winneris the party that can reply with a more coherent theoryto all theories of its adversary. (shrink)

Prompted by questions raised in the public arena concerning the validity of arguments for the existence of God based on “design” in the universe, I explore a traditional teleological argument for the existence of God. Using the arguments offered by Thomas Aquinas as fairly representative of this classical line of argumentation going back to Aristotle, I attempt to uncover the hidden premises and construct arguments for the existence of God which are deductive in nature. To justify the premises (...) of Aquinas’s argument, I begin by presenting an argument to justify the existence of “final causes,” with a focus on answering questions about the biological implications of these causes for evolutionary theory. Then, I attempt to construct two teleological proofs for the existence of God. Finally, I offer some implications of this reasoning for the contemporary disputes over ID/evolution in education.

In lieu of an abstract, here is a brief excerpt of the content:THE TELEOLOGICAL ARGUMENT JOSEPH MIXIE Rhode Island College Providence, Rhode Island I. Introduction M ANY PHILOSOPHERS think that any argument for the existence of God is " mere metaphysical speculation." Often these philosophers use the criteria of scientific empiricism as the standard for an "acceptable" scientific theory, regardless of the subject matter. While acknowledging Kuhn's work, The Structure of Scientific Revolutions, and the insights it gives (...) us regarding how the nature of scientific theories and paradigms change, it is still appropriate to ask whether any argument for the existence of God can be formulated in such a way so as to fulfill the currently acceptable criteria of scientific empiricism. I shall explore the possibility of formulating the argument from design as an empirical scientific theory. There are currently several schools of thought regarding the criteria of scientific empiricism.1 Rudolf Carnap argued in Philosophical Foundations of Physics that scientific empiricism should proceed according to verificationist methodology.2 Imre Lakatos in his work entitled Criticism and the Growth of Knowledge discusses several schools of scientific methodology including conventionalism, sophisticated methodological falsificationism, and 1 For an anthology on this subject see the essays included in Janet A. Kourany, Scientific Knowledge, Part 3, "The Validation of Scientific Knowledge," p. 112-227. 2 Rudolf Carnap, Philosophical Foundations of Physics (New York: Basic Books, 1966), chapter 2. 635 636 JOSEPH MIXIE justificationism.3 (Sect. 1, 2, and 3 of "Falsification and Methodology of Scientific Research Programs "). One major school of thought regarding the criteria of scientific empiricism is that of falsificationism. Karl Popper was one of the leading exponents of falsificationism and both presented and defended that position in his works entitled Science: Coniectures and Refutation and The Logic of Scien:tific Discovery.4 For the purposes of this paper, I will adopt Popper's criteria of falsification. II. Revised Teleological Argument I shall consider a form of the argument from design which infers the existence of God from our experience of instances of natural order. I shall discuss the notion of natural order in greater detail later in this paper. I shall not count as instances of natural order those patterns which appear randomly in nature from time to time. Consider the following formulation of the argument from design in modus ponens argument form: (1) If there are instances of natural order (N0), then there is intelligent design of these instances of natural order (D). (2) There are instances of natural order (NO). (3) Therefore, there is intelligent design of these instances of natural order (D). The acceptance of the truth of the conclusion that there is intelligent design depends upon the strength of the evidence for the antecedent-consequent relation in premise ( 1) between natural order (N0) and the existence of a designer (D). The evidence for the truth of the antecedent, required for premise (2), is provided in Section IV and I shall argue in Section VI for the acceptance of the truth of the antecedent-consequent relation. s Imre Lakatos, Criticism and the Growth of Knowledge (New York: Cambridge University Press, 1970), sections I, 2, and 3 of "Falsification and Methodology of Scientific Research Programs." 4 Karl Popper, Conjectures and Refutations (New York: Basic Books, 1962) and The Logic of Scientific Discovery (New York: Basic Books, 1959). THE TELEOLOGICAL ARGUMENT 637 III. The Scientific Criterion1 Recall Popper's method of empirical falsification. According to Popper, for a claim to qualify as empirical, a minimal requirement is that there be some evidence from experience which would indicate the claim to be false. Popper writes in The Logic of Scientific Discovery: But I shall admit a system as empirical or scientific only if it is capable of being tested by experience. These considerations suggest that not the verifiability but the falsifiability of a system is to be taken as a criteria of demarcation. In other words: I shall not require of a scientific system that it shall be capable of being singled out, once and for all, in a positive sense; but I shall require that its logical form shall be such that it can be singled out, by means of empirical tests, in a negative sense: it must be possible for an...

After a discussion of several concepts of explanation, in which the criterion of simplicity is emphasized and some interesting historical examples are used as illustration, this paper presents the cosmological and teleological arguments. The central claim is that the hypothesis of theism is more simple and elegant and so more rational than any of its alternatives.

In this article the author develops a framework for a pragma-dialectical reconstruction of teleological argumentation in a legal context. Ideas taken from legal theory are integrated in a pragma-dialectical model for analyzing and evaluating argumentation, thus providing a more systematic and elaborate framework for assessing the quality of teleological arguments in a legal context. Teleological argumentation in a legal context is approached as a specific form of pragmatic argumentation. The legal criteria that are relevant for the evaluation (...) of teleological argumentation are discussed and translated in terms of critical questions that are relevant for the evaluation of the various forms of teleological argumentation.

This is a condensed version of an in-process book on the fine-tuning argument for God’s existence. In this 48,000 word essay, I first develop a probabilistic framework for articulating the argument, and then use this framework to answer in detail many of the objections commonly raised against it. Along the way, I present some of the fine-tuning evidence itself and consider major objections against the evidence; further, there are two major sections dealing with the multiverse objection, particularly that (...) based on inflationary cosmology.

The first section of Kant’s Groundwork for the Metaphysics of Morals contains a teleological argument, the aim of which is to show that the natural purpose of human reason lies not in securing happiness but in morality. While the teleological argument is widely considered to be digressive and unconvincing in the secondary literature, in this article I attempt to show that the argument is neither digressive nor unconvincing. I argue that it fulfills an important synthetic (...) task in the Groundwork (even if in a preliminary manner), that it is consistent with Kant’s views on natural teleology at the time, and that the criticism of happiness contained therein is as convincing as Kant’s criticism of happiness in the rest of the treatise.

Recent discoveries in physics, cosmology and biochemistry have captured the public imagination and made the Design Argument - the theory that God created the world according to a specific plan - the object of renewed scientific and philosophical interest. This accessible but serious introduction to the design problem brings together new perspectives from prominent scientists and philosophers including Paul Davies, Richard Swinburne, Sir Martin Rees, Michael Behe, Elliot Sober and Peter van Inwagen.

The proofs for God's existence advanced in the most prominent theological work of Averroes (d. 1198), the Kita^b al-kashf, have been neglected, largely because the book has commonly – and correctly – been viewed as being meant for popular consumption. This article argues that although Averroes' arguments are non-technical, the Commentator nevertheless takes pains not to speak against his philosophical beliefs. Averroes distinguishes between inductive and deductive arguments, with conventional arguments from design falling into the former camp. Averroes also assigns (...) a place for teleological argumentation when assigning a special role for the prime mover within the hierarchy of unmoved movers. (shrink)

One of the most popular accounts of the teleological argument for the existence of God is the analogical account that is the center of Hume’s knocker criticisms. Since Hume’s age, many theist scholars have attempted to propose convincing responses. Motahari is one of the rigorous thinkers who tackled the challenges which Hume posed. The purpose of this paper is to address Hume’s criticisms and assess Motahari’s rejoinders to them. It will be argued that Motahari’s responses do not seem (...) successful. Although Motahari has tried to refute Hume’s criticisms in some of his works, he implicitly endorsed Hume’s assessment of the analogical account of the teleological argument in other works, and came ultimately close to the Hume’s view. As Hume believed that the argument from design is not a successful philosophical argument to prove God’s existence that the theist contend, Motahari also admits at the end that this argument alone cannot prove God’s existence and emphasizes that the argument from design cannot prove God of Abraham’s religions, that is a person with necessary being, who is immaterial and eternal, is omniscient, omnipotent, perfectly good, and the creator of the universe. Motahari ultimately believed in deficiency of the argument from design too, and assessed it as an argument with limited functions for God’s existence. (shrink)

Much has been made of how Darwinian thinking destroyed proofs for the existence of God from ‘design’ in the universe. I challenge that prevailing view by looking closely at classical ‘teleological’ arguments for the existence of God. One version championed by Aristotle and Thomas Aquinas stems from how chance is not a sufficient kind of ultimate explanation of the universe. In the course of constructing this argument, I argue that the classical understanding of teleology is no less necessary (...) in modern Darwinian biology than it was in Aristotle's time. In fact, modern biology strengthens the claims that teleological arguments make by vindicating many of their key features. As a consequence, I show how Aristotle and Aquinas' teleological argument for an intelligent First Cause remains valid. (shrink)

Kant’s claim that we must postulate the immortality of the soul is polarizing. While much attention has been paid to two standard arguments in its defense (one moral-psychological, the other rational), I contend that a favorite argument of Kant’s from the apogee of his critical period, namely, the teleological argument, deserves renewed attention. This paper reconstructs it and exhibits what makes it unique (though not necessarily superior) in relation to the other arguments. In particular, its form (as (...) third-personal or descriptive, beginning from observations) and related force of assent (as a subjectively universal reflective judgment) set it apart from the other arguments. My goal is to establish that any engagement with Kant’s immortality postulate must include equal consideration of the teleological argument in order to be complete. (shrink)

Argumentation schemes are forms of reasoning that are fallible but correctable within a self-correcting framework. Their use provides a basis for taking rational action or for reasonably accepting a conclusion as a tentative hypothesis, but they are not deductively valid. We argue that teleological reasoning can provide the basis for justifying the use of argument schemes both in monological and dialogical reasoning. We consider how such a teleological justification, besides being inspired by the aim of directing a (...) bounded cognizer to true belief and correct choices, needs to take into account the attitudes of dialogue partners as well as normative models of dialogue and communicative activity types, in particular social and cultural settings.

The famous triad of ‘rational proofs’ of God’s existence may, if their underlying intuitions are taken at face value, be reversed to prove the contrary, namely the non-existence of God. The ontological argument, for example, proceeds from the notion of God as the ‘real most’ or ‘absolutely real’ being. However, the existence of an entity thus defined must be beyond doubt, for if distinguishing between ‘levels of reality’ makes any sense at all, ‘more real’ must also mean ‘more manifest’. (...) And since a being whose existence is beyond doubt is greater than that whose existence is in doubt, God, to fit the definition provided by St. Anselm, must be a being the existence of which cannot be doubted or, more strictly, the existence of which can only come to be doubted if He did not exist to dispel all doubts. Hence it follows that God does not exist, because it is an undeniable fact that His existence is subject to doubt. This paper is not, however, about theexistence of God, it is about the inherent dialectic of theological reason that seeks non-natural or supernatural explanations for natural phenomena. (shrink)

This paper attempts to answer the question: “what are the chances that our universe should exhibit the law-like behavior we observe?” It argues that, pace the assertions of advocates of “multiverse theories” in physics, multiverses do not resolve the Fine-Tuning Problem. It makes the case that, given the principle of indifference, we should find it surprising that our universe behaves in a law-like manner.

AristotleÕs central argument for teleologyÑthough not necessarily his conclusionÑis repeated in the teleological arguments of Isaac Newton, Immanuel Kant, William Paley, and Charles Darwin. To appreciate AristotleÕs argument and its influence I assert, first, that AristotleÕs naturalistic teleology must be distinguished from PlatoÕs anthropomorphic one; second, the form of AristotleÕs arguments for teleology should be read as instances of inferences to the best explanation. On my reading, then, both NewtonÕs and PaleyÕs teleological arguments are Aristotelian while (...) their conclusions are Platonic. Kant and DarwinÕs arguments are likewise Aristotelian while their conclusions are unique. (shrink)

Many things in the natural world work so well that they seem to have been designed. But by what? Could nature itself, by processes including those of evolution, be the designer?

And if we could legitimately infer the probable existence of an intelligent designer (...) from the presence of design in the natural world, what could we then infer about that designer's nature?

In this paper I argue that teleology and a proper teleological analysis of the uterus is important for a comprehensive understanding of the rights of the unborn. I argue that a right to life entails the right to use those organs that naturally function for an individual’s survival. Consequently, an unborn child has a right to his mother’s uterus. If this is accepted, bodily-rights arguments for abortion such as those proposed by Judith Jarvis Thomson and David Boonin are completely (...) undermined. While Thomson and Boonin may be justified in arguing the right to life does not always entail the right to use another person’s body, I argue that the right to life of the unborn does entail the right to use their mother’s body.

Marjorie Grene has argued in a number of contexts that any attempt to reduce the explanation of human actions to “mechanistic” explanations is doomed to failure in advance because it is absurd. “This argument examines the status of the reductivist thesis in its own terms and reduces it to absurdity …” ; “the attempt to reduce human purposive, or ‘intentional,‘ action to physiology and ultimately to physics and chemistry is an absurdity rather than simply a confusion”. I wish to (...) show that this argument is fallacious because it involves a petitio principii; and if Plato can be credited with introducing the same argument in the Theaetetus, as she suggests, so much the worse for Plato.

This work argues that teleological motives lie at the heart of Kant's critical philosophy and that a precise analysis of teleological structures can both illuminate the basic strategy of its fundamental arguments and provide a key to understanding its unity. It thus aims, through an examination of each of Kant's major writings, to provide a detailed interpretation of his claim that philosophy in the true sense must consist of a teleologia rationis humanae. The author argues that Kant's critical (...) philosophy forged a new link between traditional teleological concepts and the basic structure of rationality, one that would later inform the dynamic conception of reason at the heart of German Idealism. The process by which this was accomplished began with Kant's development of a uniquely teleological conception of systematic unity already in the precritical period. The individual chapters of this work attempt to show how Kant adapted and refined this conception of systematic unity so that it came to form the structural basis for the critical philosophy.

Desmond Clarke's remarks on “my” absurdity argument are puzzling. i) Although I do indeed still believe it to be a valid argument, I certainly would not claim credit for it. I believe that “Reducibility: Another Side Issue?” put the general problem of the reducibility of mind into a somewhat unorthodox context, but the particular claim Clarke is attacking forms only one very unoriginal step in the general argument of that essay. ii) Some points that Clarke makes I (...) would certainly agree to, and believe I have agreed to in some of the texts he cites, while others are far from anything I meant to convey. Under Clarke's, 1) of course the “antinomies” of the paper above referred to trade on ambiguities. That's one of the points of the paper. 2) in both “Reducibility … ” and “To Have A Mind …”, I have tried to specify the sense in which “mechanism” was being used. That I do not take such terms as self-explanatory should be clear, for instance, from the remarks in the latter paper that immediately follow the passage Clarke criticizes. 3) I have no idea how physics is to develop in the future, nor did I wish to suggest that I did. With the rest of Clarke's I entirely agree. As to his, I fail to see its relevance to my argument, unless it simply leads up to and, with which, again, I wholeheartedly concur. Nancy Maull's paper, which Clarke refers to, for example, seems to me to shed great light on what used to be thought the problem of reduction; I don't see how her argument conflicts with “mine.” iii) Clarke's two “interpretations” of “my” argument are even more puzzling. The first paragraph is clear, as far as it goes. But the second is entirely murky. Perhaps I may try to reconstruct it. “The question for the scientist of a reductivist disposition in this context,” Clarke writes, “is: would it be possible to construct an alternative theory which adequately explains the same phenomena as the human sciences?” Fair enough. But apparently one is not allowed to reflect about an answer to this question. One has to wait and see if such a theory does develop. And meantime to notice that any theory by its very nature is intentional: this is to use some part of the human sciences to establish the explanatory power of all the human sciences. Is that what is meant? If so, I would reply: that the claim that theories are inherently intentional is not a thesis of any “human science” but a philosophical thesis about the nature of intelligible discourse. If a wholly non-intentional theory of human action were stated it would invalidate itself as theory. Thus, to respond to the major accusation of, we would have an answer to Clarke's question such that the question could not have been asked. What we have, then, is not a petitio but a valid reductio ad absurdum. (shrink)

The notions of purpose, goal, end and function are used in descriptions of a very wide range of human, animal and machine behaviour. Andrew Woodfield provides here a unified account of such teleological descriptions and explanations, their varieties, their logical structure and their proper uses. He concentrates his argument on the concepts of 'goal-directed behaviour' and 'natural function', and combines original philosophical criticism with a meticulous, detailed survey of the main competing theories in this diffuse and difficult field.

The article is devoted to the historical analysis of teleological argumentation evolution in the legal interpretation. The ideas of ancient Greek and Roman orators, philosophers and lawyers, which served as the basis for development of the idea of teleological interpretation in the European legal tradition, are examined. The history of teleological interpretation method development in European legal theory from Medieval jurists to sociological legal approach of the late 19 th and 20 th centuries is observed, as well (...) the existence of two main approaches in understanding the teleological method of interpretation, namely subjective-teleological and objective-teleological, is ascertained. The author states that there is a direct correlation between the concept of law and the approach to understanding of the teleological interpretation method. In conclusion, the author insists on the more progressive nature of the objective-teleological method of legal interpretation. (shrink)

In Gaudium et Spes and Dignitatis Humanae the Second Vatican Council not only presents the dignity of the human person as the parting point for its moral teaching but also grounds human dignity in natural teleology. Natural teleology is the view that the good of any thing corresponds to, and so can be discerned from, the ends to which it is directed by its nature, both that end which is proper to it and those ends that it has as part (...) of a wider order. As official Church teachings, these documents refrain from providing a philosophical justification of their account of human dignity. The existence of natural teleology, however, is generally contested in modern philosophy. For this reason, grounding human dignity in natural teleology constitutes a questionable approach to the issue. Of all major Catholic theologians, Thomas Aquinas is arguably the one who provides the most developed philosophical resources for articulating these views on natural teleology and its connection with human dignity. This paper examines and assesses the way in which he grounds human dignity in natural teleology. In his view, we see that human beings are the principle part of the universe and that the other parts of the universe are ordered towards the good of human beings. After surveying his general justification of how a thing is ordered to particular ends in virtue of its nature, the paper considers his explanation of how each part of the universe assumes further ends within the universe as a whole, and his main set of arguments on how we perceive human dignity against the backdrop of the natural teleology of the universe.

This paper argues that biological organisation can be legitimately conceived of as an intrinsically teleological causal regime. The core of the argument consists in establishing a connection between organisation and teleology through the concept of self-determination: biological organisation determines itself in the sense that the effects of its activity contribute to determine its own conditions of existence. We suggest that not any kind of circular regime realises self-determination, which should be specifically understood as self-constraint: in biological systems, in (...) particular, self-constraint takes the form of closure, i.e. a network of mutually dependent constitutive constraints. We then explore the occurrence of intrinsic teleology in the biological domain and beyond. On the one hand, the organisational account might possibly concede that supra-organismal biological systems could realise closure, and hence be teleological. On the other hand, the realisation of closure beyond the biological realm appears to be highly unlikely. In turn, the occurrence of simpler forms of self-determination remains a controversial issue, in particular with respect to the case of self-organising dissipative systems. (shrink)

This paper connects veritistic teleological epistemology, VTE, with the epistemological dimension of the scientific realism debate. VTE sees our epistemic activities as a tradeoff between believing truths and avoiding error. I argue that van Fraassen’s epistemology is not suited to give a justification for a crucial presupposition of his Bad Lot objection to inference to the best explanation (IBE), the presupposition that believing that p is linked to p being more likely to be true. This makes him vulnerable to (...) a counterargument, tailored after Musgrave’s defense of IBE, which would result in a stalemate between them about presuppositions of rationality. I will, however, show that switching to VTE can justify van Fraassen’s presupposition. This leads to a dismissal of common IBE arguments for realism as presented by Boyd and Musgrave, but I also argue that a more cautious version of realism can be rescued from the Bad Lot objection. Finally, I raise some worries about epistemic risk-attitude consistency for constructive empiricists and develop an alternative anti-realist position.1. (shrink)

Teleology in biology is making headline news in the United States. Conservative Christians are utilizing a teleological argument for the existence of a supremely intelligent designer to justify legislation calling for the teaching of "intelligent design" (ID) in public schools. Teleological arguments of one form or another have been around since Antiquity. The contemporary argument from intelligent design varies little from William Paley's argument written in 1802. Both argue that nature exhibits too much complexity to (...) be explained by 'mindless' natural forces alone. We need to postulate the existence of an intelligent designer, a creator with forethought and purpose. The inference to an intelligent creator harkens back to Plato’s teleological argument for the order of the cosmos. Plato’s demiurge is a creator that imposes order on the cosmos. Yet, as we shall see when we analyze the distinctly biological form of the more contemporary teleological arguments we will find remanants of Aristotle’s distinctive argument from functional arrangement, but without his distinctive form of telos which is unconscious and immanent rather than intelligent and creative from on high. The aim of this article is to survey various teleological arguments since Antiquity. Since a variant on Paley's argument—ID—is getting so much recent press I will start with a discussion on the nature of Paley’s teleology. (shrink)

Aristotle articulates his natural teleology in the context of a dialectical engagement with his predecessors, identifying each of them with a salient causal factor: Empedocles, Democritus, Anaxagoras, and Plato. Aristotle tries to co-opt each of these factors into his naturalistic teleology by an a fortiori argument: to the extent that luck, necessity, intelligence, or art is a cause, nature must even more so be considered a cause. For luck is an incidental cause of that which nature is an intrinsic (...) cause, necessity is a conjoint cause of that which nature is a leading cause, and art imitates nature. (shrink)

The relation of teleological to causal explanations in psychology is examined. Nagel's claim that they are logically equivalent is rejected. Two arguments for their non-equivalence are considered: (i) the impossibility of specifying initial conditions in the case of teleological explanations and (ii) the claim that different kinds of logic are involved. The view that causal explanations provide only necessary conditions whereas teleological explanations provide sufficient conditions is rejected: causal explanations can provide sufficient conditions, typically being unable to (...) provide necessary ones, whereas teleological explanations tend to point to necessary features. Nor is a distinction in terms of intensional and extensional logic entirely satisfactory, although there is some support for the view that teleological and causal explanations invoke different types of explanatory framework. A key feature of teleogical explanation is the achievement of the same goal by a variety of means. Thus its main scientific function is likely to be heuristic rather than predictive. (shrink)
