Philosophical naturalism, according to which philosophy is continuous with the natural sciences, has dominated the Western academy for well over a century, but Michael Rea claims that it is without rational foundation. Rea argues compellingly to the surprising conclusion that naturalists are committed to rejecting realism about material objects, materialism, and perhaps realism about other minds.

This paper defends the conclusion that every epistemic truth equivalence entails "near theism"--the view that (i) there exists a necessarily existent rational community and (ii) necessarily, there exists an omnisicent community.

It seems to be a widely shared view that any defensible desire-fulfillment theory of welfare must be framed not in terms of what an agent, in fact, desires but rather in terms of what an agent would desire under hypothetical conditions that include improved information. Unfortunately, though, such accounts are subject to serious criticisms. In this paper I show that in the face of these criticisms the best response is to jettison any appeal to idealized information conditions: the considerations put (...) forward in support of the appeal to what would be desired in hypothetical circumstances of improved information do not, in fact, give adequate reason to make that appeal.

In _Realistic Rationalism_, Jerrold J. Katz develops a new philosophical position integrating realism and rationalism. Realism here means that the objects of study in mathematics and other formal sciences are abstract; rationalism means that our knowledge of them is not empirical. Katz uses this position to meet the principal challenges to realism. In exposing the flaws in criticisms of the antirealists, he shows that realists can explain knowledge of abstract objects without supposing we have causal contact with them, that numbers (...) are determinate objects, and that the standard counterexamples to the abstract/concrete distinction have no force. Generalizing the account of knowledge used to meet the challenges to realism, he develops a rationalist and non-naturalist account of philosophical knowledge and argues that it is preferable to contemporary naturalist and empiricist accounts. The book illuminates a wide range of philosophical issues, including the nature of necessity, the distinction between the formal and natural sciences, empiricist holism, the structure of ontology, and philosophical skepticism. Philosophers will use this fresh treatment of realism and rationalism as a starting point for new directions in their own research. (shrink)

First, The doctrine of naturalism, That reality is spatio-Temporal, Is defended. Second, The doctrine of materialism or physicalism, That this spatio-Temporal reality involves nothing but the entities of physics working according to the principles of physics, Is defended. Third, It is argued that these doctrines do not constitute a "first philosophy." a satisfactory first philosophy should recognize universals, In the form of instantiated properties and relations. Laws of nature are constituted by relations between universals. What universals there are, And what (...) relations hold between them, Must be discovered "a posteriori" by scientific investigation.

_Naturalism_ provides a rigorous analysis and critique of the major varieties of contemporary philosophical naturalism. The authors advocate the thesis that contemporary naturalism should be abandoned, in light of the serious objections raised against it. Contributors draw on a wide range of topics including: epistemology, the philosophy of science, the philosophy of mind and agency, and natural theology.

Introduction The Many Moral Realisms Geoffrey Sayre-McCord I. Introduction Recognizing the startling resurgence in realism, ...

A realistic and dialectical conception of the epistemology of science is advanced according to which the acquisition of instrumental knowledge is parasitic upon the acquisition, by successive approximation, of theoretical knowledge. This conception is extended to provide an epistemological characterization of reference and of natural kinds, and it is integrated into recent naturalistic treatments of knowledge. Implications for several current issues in the philosophy of science are explored.

The chapter has four parts. In the first, I argue that we can be justified in believing that there are mind-independent material objects only if we can be justified in believing that modal properties are exemplified in at least some of the regions of space-time that we take to be occupied by material objects. In the second, I argue that we can be justified in believing that modal properties are exemplified in a region only if we can be justified in (...) classificatory judgments--judgments like 'this region contains an F', where 'F' is a name for a natural kind and furthermore constitutes a metaphysically better answer to the question, "What kind of object is in that region?" than any name for any other kind. In the third part, I dismiss as failures three views about how naturalists might be able to be justified in classificatory judgments. I consider a fourth which presupposes that, if there are material objects, then we are justified in believing that science reveals some of them to have proper functions; and I note that if this fourth proposal fails, there is good reason to think that any other proposal will as well. In the final section I argue that this fourth proposal does indeed fail by showing that there are material objects, science does not reveal any of them to have proper functions. If I am right, and if (as seems plausible) we are justified in believing that there exist mind-independent material objects (e.g. people), then we ought to reject naturalism. (shrink)
