The terminal philosopher thinks there must always be beliefs or other posits that are terminal: they can neither be justified nor criticized by inference from anything further. In any context whatever, reason giving must at some point leave off - not for practical reasons, such as lack of time, energy or resources, but in principle. No further argumentative recourse is possible at this level of fundamentality. The terminal matters must therefore be justified or criticized non-inferentially - that is to say, (...) immediately - or not at all. Most terminal philosophers conclude "Not at all," on the ground that there is no such thing as unmediated knowledge, justification or critique. (shrink)
. In whatever form, terminal philosophy holds that some matters are so fundamental that they are presupposed in any practice of reason-giving; accordingly, if reason-giving were applied to such matters in order to justify them, or even to criticize, then the very attempt to do so would necessarily assume what is at issue, a fatal circularity . No further argumentative recourse is possible at this level of fundamentality ; rational reason-giving must terminate.
This collection of eleven critical essays, together with Plantinga's replies, examines his evolutionary argument against naturalism (EAAN). All but one of the eleven are printed here for the first time, all are of high quality, and all receive Plantinga's trademark treatment -- rigorous, perceptive, thorough. In view of the numerous arguments, sub-arguments and observations advanced by the eleven against EAAN, his responses amount to a tour de force . It would take too long to sort through the point-counterpoint with a (...) view to laying out the many interconnections, valuable though that would be. Instead, after a sketch of EAAN, I summarize some of the key objections raised by the eleven, together with Plantinga's replies, then conclude with an objection of my own to what Plantinga calls the heart of his argument.

They say it can't be done . You can't use language to get outside language . The very idea . Thus Putnam : "our language cannot be divided up into two parts, a part that describes the world `as it is anyway,' and a part that describes our conceptual contribution," in order..
To ask the question "Why does anything at all exist?" is equivalent to asking "What is the explanation of why anything at all exists." Thus the question presupposes that there is an explanation, known or unknown or unknowable, of why anything at all exists.
David Papineau’s model of scientific reduction, contrary to his intent, appears to enable a naturalist realist account of the primitive normativity involved in a biological adaptation’s being “for” this or that (say the eye’s being for seeing). By disabling the crucial anti-naturalist arguments against any such reduction, his model would support a cognitivist semantics for normative claims like “The heart is for pumping blood, and defective if it doesn’t.” No moral claim would follow, certainly. Nonetheless, by thus “pressing from below” (...) we may learn something about moral normativity. For instance, suppose non-cognitivists like Mackie are right that the semantics of normative claims should be “unified”: if the semantics of moral claims is non-cognitivist, so too is that of all normative claims. Then, assuming that a naturalist reduction does yield a sound cognitivist account of the primitive normativity, it would follow that our semantics of moral claims is cognitivist as well. (shrink)
I am indebted to Richard Gale and Alexander Pruss for the excellent questions they raise in their separate responses to my comments on Gale's book, On the Nature and Existence of God ."(1) They focus on aspects of my discussion that need at least to be clarified, if not retracted, in ways I hope to explain in what follows. But first let me call attention to a couple of arguments they do not mention.

The method in question is conceptual analysis. The madness comes of its privileging received usage over theories that would revise our concepts so as to conform to the phenomena, not the other way around. The alternatives to capture-the-concept include revisionary theory-construction as practiced not only in the sciences but in some philosophies. I present a revisionary theory of an important kind of normativity -- the normativity involved in a biological adaptation's being for this or that -- which theory, (...) I argue, undermines the received objections to there being any such normativity objectively in the world. So too for other kinds of normativity, including the moral, insofar as the objections to their objectivity have the same form and presuppositions. (shrink)
Adhering to the traditional concept of omniscience lands Gale in the incoherence Grim's Cantorian arguments reveal in talk of all propositions. By constructing variants and extensions of Grim's arguments, I explain why various ways out of the incoherence are unacceptable, why theists would do better to adopt a certain revisionary concept of omniscience, and why the Cantorian troubles are so deep as to be troubles as well for Gale's Weak Principle of Sufficient Reason. I conclude with some brief reflections on (...) method, suggesting that we pursue the full implications of Gale's own revisionary remarks and replace his method of analytic argumentation with non-analytic revisionary theory-construction.

Abstract. Alleged counter-examples based on conceptual thought-experiments, including those involving sense or content, have no force against physicalist supervenience theses properly construed. This is largely because of their epistemological status and their modal status. Still, there are empirical examples that do contradict Kim-style theses, due to the latter's individualism. By contrast, non-individualist supervenience, such as "global" supervenience, remains unscathed, a possibility overlooked by Lynne Baker, as is clear from a physicalist account of sense in the case of non-human biological adaptations (...) that are for producing things about affairs in the world.

Argues for an objective protomoral normativity in terms of what an adaptation is for, without falling victim to Hume's Law, open-question arguments, queerness arguments, and internalism/externalism debates. Also provides a general strategy for naturalizing objective moral normativity which is likewise proof against the usual-suspect objections.
After some preliminary clarifications, arguments for the supposed asymmetry of supervenience and determination, such as they are, are shown to be unsound. An argument against the supposed asymmetry is then constructed and defended against objections. This is followed by explanations of why the intuition of asymmetry is nonetheless so entrenched, and of how the asymmetric ontological priority of the physical over the non-physical can be understood without the supposed asymmetry of supervenience and determination.
In order to defend the regress argument for foundationalism against Post’s objection that relevant forms of inferential justification are not transitive, Lydia McGrew and Timothy McGrew define a relation E of positive evidence, which, they contend, has the following features: It is a necessary condition for any inferential justification; it is transitive and irreflexive; and it enables both a strengthened regress argument proof against Post’s objection and an argument that nothing can ever appear in its own justificational ancestry. In reply, (...) we construct in their own terms both a counterexample to the would-be transitivity of E, and a related objection to their never-in-its-own-ancestry argument. We also rebut their rejection of certain counterexamples to the would-be transitivity of some forms of inferential justification. By doing so, and by questioning their transitivity claim for E, we aim to further the project of undermining the circularity arguments advanced by a zoo of skeptics, relativists, antirealists and internalists against realism and externalism.

New-wave psychoneural reduction, a la Bickle and Churchland, conflicts with the way certain adaptation properties are individuated according to evolutionary biology. Such properties cannot be reduced to physical properties of the token items that have the adaptation properties. The New Wave may entail a form of individualism inconsistent with evolutionary biology. All of this causes serious trouble as well for Jaegwon Kim's thesis of the Causal Individuation of Kinds, his Weak Supervenience thesis, Alexander's Dictum, his synchronicity thesis that all psychological (...) kinds supervene on the contemporaneous physical states of the organism, Correlation Thesis, and indeed his Restricted Correlation Thesis. All these theses are strongly individualist, in the sense of entailing that ALL a thing's properties are determined by its own physical properties and relations, contrary to many properties in biology and psychology.

Outlines a conceptual argument against the Principle of Sufficient reason. The argument is presented in detail in earlier work, and is based on deductive inferences from PSR's own concept of explanation. The argument shows that not everything can have an explanation of the sort claimed by PSR. So far from being a presupposition of reason itself, as some think, PSR can be refuted by reason, arguing only from PSR's own concept of explanation. Hence PSR cannot be used to argue that (...) there must be some explanation or reason for existence, invisible at least to science, or that because we do not or cannot know the explanation, there must be irreducible mystery about why there is anything at all rather than nothing, including why there was a Big Bang in the first place.

The foundationalism in irrealism is structural foundationalism, according to which reason giving must terminate with some affair beyond the reach of noncircular inferential justification or critique. Even relativist irrealists are structural foundationalists. But structural foundationalism is only as good as the regress argument for it, which presupposes that the relevant forms of inferential justification are all transitive. Since they are not, structural foundationalism fails. So too does the “God’s-eye-view” or look-see argument against realism, to the effect that when it comes (...) to correspondence and universals or samenesses found not made, realists have no noncircular argumentative recourse, hence must gaze on reality bare, looking to see that the categories of our language or thought conform to something in reality. Furthermore, realists can justify their view via nontransitive forms of inferential justífication, without recourse either to look-see or to morally problematic notions of sameness and difference made rather than lovingly found.

"Adaptation properties," as individuated according to evolutionary biology, cannot be reduced to physical properties of the token items that have the adaptation properties. This causes serious if not fatal trouble for several of Kim's crucial theses: the Causal Individuation of Kinds, Weak Supervenience, Alexander's Dictum, the synchronicity thesis (that all psychological kinds supervene on the contemporaneous physical states of the organism), the Correlation Thesis, and indeed his Restricted Correlation Thesis. All these theses are strongly individualist, in the sense of entailing (...) that all a thing's properties are determined by its own physical properties and relations, contrary to many properties in biology and psychology.

Collingwood's theory of presuppositions has never been taken very seriously. But critics have completely overlooked its significance as a theory or model of inquiry intimately tied to certain aspects of discourse in a context of investigation. Viewed this way, Collingwood's theory is on very strong ground, especially when it is reconstructed with the aid of a formal language. The reconstruction shows what is essential to the theory and what is not, allowing us to disregard those of Collingwood's extravagant claims which (...) have frustrated an understanding of his theory's real strength. The reconstruction also provides a general framework within which recent discussion of presuppositions can be unified. (shrink)
