Wittgenstein's Anti‐Platonist Argument

Many interpreters have noted that §§138–242 of Wittgenstein's Philosophical Investigations is dominated by an attack on a platonist or classical realist conception of rules and meaning. In this paper, I address the lack of clarity that still exists concerning the nature and strength of the arguments in those sections. I argue that Wittgenstein's attack is genuinely compelling if viewed as an intricate reductio ad absurdum argument that runs all the way through §§138–201. On my reading, the well‐known regress‐of‐interpretations argument is merely one stage in the overall reductio and is not sufficient on its own to generate the rule‐following paradox.     

Genetic modification and genetic determinism

In this article we examine four objections to the genetic modification of human beings: the freedom argument, the giftedness argument, the authenticity argument, and the uniqueness argument. We then demonstrate that each of these arguments against genetic modification assumes a strong version of genetic determinism. Since these strong deterministic assumptions are false, the arguments against genetic modification, which assume and depend upon these assumptions, are therefore unsound. Serious discussion of the morality of genetic modification, and the development of sound science policy, should be driven by arguments that address the actual consequences of genetic modification for individuals and society, not by ones propped up by false or misleading biological assumptions.     

Radical quotation and real repetition

In this essay I argue for a constructivist account of the entities composing the object languages of Davidsonian truth theories and a quotational account of the reference from metalinguistic expressions to interpreted utterances. I claim that ‘radical quotation’ requires an ontology of repeatable events with strong similarities to Derrida's account of iterable events. In part one I summarise Davidson's account of interpretation and Olav Gjelsivk's arguments to the effect that the syntactic individuation of linguistic objects is only workable if interpreters make richer assumptions about semantic properties than Davidson can tolerate. In part two I show that the objectivist account of syntactic objects which Gjelsivk's arguments presuppose is incompatible with one corollary of Davidsonian semantic indeterminacy: namely, the relativity of language to interpretative scheme. In place of this an account of radical interpretation is presented in which a quotational theory of metalinguistic reference furnishes the requisite relativity. In part three I argue that this account requires that particular utterance events must be repeatable to be radically quotable and give reasons why particularity and repeatability are not incompatible.     

Kripke's sole route to the necessary a posteriori

In ‘Kripke on epistemic and metaphysical possibility: two routes to the necessary a posteriori’, Scott Soames identifies two arguments for the existence of necessary a posteriori truths in Naming and Necessity (NN). He argues that Kripke's second argument relies on either of two principles, each of which leads to contradiction. He also claims that it has led to ‘two-dimensionalist’ approaches to the necessary a posteriori which are fundamentally at odds with the insights about meaning and modality expressed in NN. I argue that the alleged second argument is not in NN. I identify the mistakes that lead to Soames' misinterpretation.     

German Idealism and the Concept of Punishment

This paper examines the Leibnizian background to Kant's critique of the ontological argument. I present Kant's claim that existence is not a real predicate, already formulated in his pre-critical essay of 1673, as a generalization of Leibniz's reasoning regarding the existence of created things. The first section studies Leibniz's equivocations on the notion of existence and shows that he employs two distinct notions of existence – one for God and another for created substances. The second section examines Kant's position in his early paper of 1763. My claim is that Kant's view of existence in 1763, namely that it is not a predicate, is strongly related to the logical notion of possibility, formulated by Leibniz and accepted by Kant.     

Emilie du Châtelet on the Existence and Nature of God: An Examination of Her Arguments in Light of Their Sources

Many commentators have suggested that the metaphysical portions of Emilie du Châtelet's Institutions de physique are a mere retelling of Leibniz's views. I argue that a close reading of the text shows that du Châtelet's cosmological argument and discussion of God's nature contains both Lockean and Leibnizian elements. I discuss where she follows Locke in her arguments, what Leibnizian elements she brings in, and how this enables her to avoid some of the mistakes commonly attributed to Locke's formulation of the cosmological argument. I show that while du Châtelet accepts the causal principle ex nihilo nihil fit, she does not utilize Locke's stronger causal principle. I also discuss her use of the principle of sufficient reason in both improving the Lockean cosmological argument and in proving the attributes of God.     

Vagueness and Margin for Error Principles*

Timothy Williamson's potentially most important contribution to epistemicism about vagueness lies in his arguments for the basic epistemicist claim that the alleged cut‐off points of vague predicates are not knowable. His arguments for this are based on so‐called ‘margin for error principles’. This paper argues that these principles fail to provide a good argument for the basic claim. Williamson has offered at least two kinds of margin for error principles applicable to vague predicates. A certain fallacy of equivocation (on the meaning of ‘knowable’) seems to underlie his justification for both kinds of principles. Besides, the margin for error principles of the first kind can be used in the derivation of unacceptable consequences, while the margin for error principles of the second kind can be shown to be compatible with the falsity of epistemicism, under a number of assumptions acceptable to the epistemicist.     

The Moral Argument for the Existence of God and Immortality

This essay tries to show that there exist several passages where Kierkegaard (and his pseudonyms) sketches an argument for the existence of God and immortality that is remarkably similar to Kant's so‐called moral argument for the existence of God and immortality. In particular, Kierkegaard appears to follow Kant's moral argument both when it comes to the form and content of the argument as well as some of its terminology. The essay concludes that several passages in Kierkegaard overlap significantly with Kant's moral argument, although Kierkegaard ultimately favors revealed faith over natural theology in general and Kant's moral faith in particular. Whereas Kant uses the moral argument to postulate the existence of God and immortality, Kierkegaard mainly uses it as a reductio ad absurdum of non‐religious thinking.     

Formal Proper Parts through Strong Supplementation: A Reply to Bennett

Kathrin Koslicki argues that ordinary material objects like tables and motorcycles have formal proper parts that structure the material proper parts. Karen Bennett rejects a key premise in Koslicki's argument according to which the material ingredient out of which a complex material object is made is a proper part of that object. Koslicki defends this premise with a principle motivated by its power to explain three important phenomena of material composition. But these phenomena can be equally well explained by a weaker principle that does not support the questioned premise in Koslicki's argument, Bennett argues. I show that Bennett's weaker principle, together with an appropriate strengthening of a different premise in Koslicki's original argument, still yields a sound argument for the existence of formal parts.     

WITTGENSTEIN ON ACCORD*

Abstract: The paper deals with the interpretation of Wittgenstein's views on the power of occurrent mental states to sort objects or states of affairs as in accord or in conflict with them, as presented in the rule‐following passages of the Philosophical Investigations. I shall argue first that the readings advanced by Saul Kripke and John McDowell fail to provide a satisfactory construal of Wittgenstein's treatment of a platonist account of this phenomenon, according to which the sorting power of occurrent mental states is to be explained by reference to the mind's ability to grasp universals. I contend that the argument that Kripke extracts from Wittgenstein's discussion doesn’t succeed in undermining the platonist position. Then I argue that McDowell's reading exhibits a more serious shortcoming: the position that he ascribes to Wittgenstein is indistinguishable from the platonist account. Then I put forward a proposal as to how to articulate the relationship between Wittgenstein's views and the platonist position.     

Just open borders? Examining Joseph Carens' open borders argument in the light of a case study of recent Somali migrants to the UK

This essay examines Joseph Carens' open borders argument in the light of a case study of recent Somali migrants to the UK. It argues that, although arguments for significantly more open borders are compelling, they must take into account existing domestic injustice in receiving states as well as existing global injustice.     

The influence of argument structure on judgements of argument strength,function, and adequacy

The present study explored the extent to which lay adults consider aspects of argument structure in judging the strength and function of informal arguments and in constructing arguments to meet specific adequacy goals. Across two experiments, college students were presented with base (one-premise) arguments, which were then expanded into convergent, coordinate, and subordinate arguments closely matched in terms of content, believability, and strength. Coordinate arguments were associated with the greatest gains in argument strength via their construction and the greatest loss in strength when one of their premises was falsified. To some degree, the argument types were also judged to perform different functions and to serve different goals. The construction of convergent arguments was associated with building independent lines of support while the construction of subordinate arguments was associated with providing justification for premises. Expansion into a coordinate argument was seen as the best way to improve an argument's persuasiveness. The construction of both coordinate and subordinate arguments was associated with building relevance, explicating assumptions, and completing the meaning of a base argument. Results are discussed in terms of argumentation theory and research.     

The Cartesian Context of Berkeley's Attack on Abstraction

Abstract: I claim that Berkeley's main argument against abstraction comes into focus only when we see Descartes as one of its targets. Berkeley does not deploy Winkler's impossibility argument but instead argues that what is impossible is inconceivable. Since Descartes conceives of extension as a determinable, and since determinables cannot exist as such, he falls within the scope of Berkeley's argument.     

Are Fallacies Vices?

Why are some arguments fallacious? Since argumentation is an intellectual activity that can be performed better or worse, do we evaluate arguments simply in terms of their content, or does it also make sense to evaluate the arguer in light of the content put forward? From a ‘virtue’ approach, I propose understanding fallacies as having some link with intellectual vice(s). Drawing from recent work by Paul Grice, Linda Zagzebski, Andrew Aberdein, and Douglas Walton, this essay argues that if there is some sense of argumentation where an argument is (1) truth-propagating and not (2) put forward in order to ‘win’, fallacies may be the vicious element in arguments that undermines (1), most often because the arguer’s goal is only (2). From this perspective, fallacies may not only be improper ‘moves’ in an argument, but may also reveal something lacking in the arguer’s intellectual character.     

Lowe's Argument Against the Psychoneural Token Identity Thesis

E. J. Lowe argues that the mental event token cannot be identical to the complex neural event token for they have different counterfactual properties. If the mental event had not occurred, the behavior would not have ensued, while if the neural event had not occurred, the behavior would have ensued albeit slightly differently. Lowe's argument for the neural counterfactual relies on standard possible world semantics, whose evaluation of such counterfactuals is problematic. His argument for the mental counterfactual relies on a premise that is plausibly false. My arguments support other counterfactuals, which are consistent with identity theories.     

Locke and Leibniz on Religious Faith

In the Essay Concerning Human Understanding, Locke maintains that ‘Reason must be our last Judge and Guide in every Thing,’ including matters of religious faith, and this commitment to the primacy of reason is not abandoned in his later religious writings. This essay argues that with regard to the relation between reason and religious faith, Locke is primarily concerned not with evidence, but with consistency, meaning, and how human beings ought to respond to their inclinations, including their inclinations to believe. Leibniz, on the other hand, stakes out an alternative conception of the relationship between faith and reason that assigns to faith the role of a primary truth. For Leibniz, some religious propositions can be believed immediately and without an additional examination and evaluation by reason. The essay maintains that the differences between the two regarding faith and reason are tied to a broader disagreement about how much of the human understanding is due, in Locke's words, to ‘Labour, Attention and Industry’.     

Schopenhauer's Pessimism

My purpose in this essay is to clarify and evaluate Arthur Schopenhauer's grounds for the view that happiness is impossible. I shall distinguish two of his arguments for that view and argue that both of them are unsound. Both arguments involve premises grounded on a problematic view, namely, that desires have no objects. What makes this view problematic is that, in each of the two arguments, it conflicts with Schopenhauer's grounds for other premises in the argument. I shall then propose a way of fixing both arguments. The solution involves substituting the view that desires have no objects with the view that we have a desire to have desires. The latter view, I shall argue, can do the grounding work that the former does in Schopenhauer's arguments but, unlike it, the view that we desire to desire is consistent with Schopenhauer's grounds for the rest of premises in those arguments.     

Leibniz's Two Realms Revisited

Leibniz speaks, in a variety of contexts, of there being two realms—a “kingdom of power or efficient causes” and “a kingdom of wisdom or final causes.” This essay explores an often overlooked application of Leibniz's famous “two realms doctrine.” The first part turns to Leibniz's work in optics for the roots of his view that nature can be seen as being governed by two complete sets of equipotent laws, with one set corresponding to the efficient causal order of the world, and the other to its teleological order. The second part offers an account of how this picture of lawful over‐determination is to be reconciled with Leibniz's mature metaphysics. The third addresses a line of objection proposed by David Hirschmann to the effect that Leibniz's doctrine undermines his stated commitment to an efficient, broadly mechanical account of the natural world. Finally, the fourth part suggests that Leibniz's thinking about the harmony of final and efficient causes in connection with corporeal nature may help to shed light on his understanding of the teleological unfolding of monads as well.     

Five arguments on the rationality of suicide terrorists

This is a critical review of five arguments against the scholarly consensus that individual suicide terrorists are rational actors. The first three arguments are analytic, meaning that they hold that suicide terrorism is inherently irrational, based on assumptions regarding the nature of the perpetrators' interests as individuals. The fourth argument is empirical, based on alleged evidence of suicide terrorist psychopathology. And the fifth argument is pragmatic, based on the strategic implications of ‘conceding’ the status of rationality to enemies. This article highlights weaknesses in these arguments and considers assessing the rationality of suicide terrorists by measuring their act to cultural or community goals subject to a division of labor principle.     

Hegel on Space: A Critique of Kant's Transcendental Philosophy

This paper considers Hegel's views on space and his account of Kant's theory of space. I show that Hegel's discussions of space exhibit a deep understanding of Kant's apriority argument in the first Critique , commit him to the central premise of that argument, and separate his concerns from the familiar problem of the neglected alternative. Nevertheless, Hegel makes two objections to Kant's theory of space. First, he argues that the theory is internally inconsistent insofar as Kant's identification of space with an a priori intuition is incompatible with the doctrine of productive imagination in the transcendental deduction of the categories. Second, Hegel argues that the apriority argument is insufficiently critical insofar as it relies upon an unexamined theory of subjectivity as a set of representational capacities. I conclude by outlining Hegel's strategy for undermining the assumptions concerning subjectivity that give form to Kant's transcendental philosophy. Because Hegel's positive views on space depend upon his articulation of an alternate notion of subjectivity, the account of Hegel's position on space offered here remains incomplete. On the other hand, considering Hegel's discussions of space demonstrates both the nature and the importance of his examination of subjectivity in the Phenomenology.
