While C. I. Lewis was traditionally interpreted as an epistemological foundationalist throughout his major works, virtually every recent treatment of Lewis's epistemology dissents. But the traditional interpretation is correct: Lewis believed that apprehensions of "the given" are certain independently of support from, and constitute the ultimate warrant for, objective empirical beliefs. This interpretation proves surprisingly capable of accommodating apparently contrary textual evidence. The non-foundationalist reading, by contrast, simply cannot explain Lewis's explicit opposition to coherentism and his insistence that only apprehensions (...) of the given enable us to answer the regress problem -- and so vindicate the possibility of empirical justification.

On an ordinary view of the relation of philosophy of science to science, science serves only as a topic for philosophical reflection, reflection that proceeds by its own methods and according to its own standards. This ordinary view suggests a way of writing a global history of philosophy of science that finds substantially the same philosophical projects being pursued across widely divergent scientific eras. While not denying that this view is of some use regarding certain themes of and particular time (...) periods, this essay argues that much of the epistemology and philosophy of science in the early twentieth century in a variety of projects looked to the then current context of the exact sciences, especially geometry and physics, not merely for its topics but also for its conceptual resources and technical tools. This suggests a more variable project of philosophy of science, a deeper connection between early twentieth-century philosophy of science and its contemporary science, and a more interesting and richer history of philosophy of science than is ordinarily offered.

The mind-body problem in contemporary philosophy has two parts: the problem of mental causation and the problem of consciousness. These two parts are not unrelated; in fact, it can be helpful to see them as two horns of a dilemma. On the one hand, the causal interaction between mental and physical phenomena seems to require that all causally efficacious mental phenomena are physical; but on the other hand, the phenomenon of consciousness seems to entail that not all mental phenomena are (...) physical.2 One may avoid this dilemma by adopting an epiphenomenalist view of consciousness, of course; but there is little independent reason for believing such a view. Rejecting epiphenomenalism, then, leaves contemporary philosophers with their problem: mental causation inclines them towards physicalism, while consciousness inclines them towards dualism. (shrink)

It is usually assumed that what Lewis says about the given in Mind and the World-Order (MWO) and An Analysis of Knowledge and Valuation (AKV) is essentially the same, and that both works are defenses of foundationalism. However, this assumption faces two problems: first, it is difficult to bring Lewis's diverse remarks on the given into coherence, especially when those in MWO are compared with those in AKV; and second, though AKV is a defense of foundationalism, there is much in (...) MWO that can be read as a critique of foundationalism. In this paper a different reading of Lewis is proposed, one that avoids these problems. This is developed by going farther back in Lewis, to his Harvard Ph.D. dissertation, The Place of Intuition in Knowledge (PIK). By tracing Lewis's discussion of the given from PIK through MWO up to AKV, it is shown that the phrase 'the given' is used to refer to two different doctrines, and that Lewis's position on foundationalism undergoes a fundamental change, roughly, from indifference to rejection to acceptance.

Over the last thirty years, a group of philosophers associated with the University of Pittsburgh—Robert Brandom, James Conant, John Haugeland, and John McDowell—have developed a novel reading of Kant. Their interest turns on Kant’s problem of objective purport: how can my thoughts be about the world? This paper summarizes the shared reading of Kant’s Transcendental Deduction by these four philosophers and how it solves the problem of objective purport. But I also show these philosophers radically diverge in how they view (...) Kant’s relevance for contemporary philosophy. I highlight an important distinction between those that hold a quietist response to Kant, evident in Conant and McDowell, and those that hold a constructive response, evident in Brandom and Haugeland. The upshot is that the Pittsburgh Kantians have a distinctive approach to Kant, but also radically different responses to his problem of objective purport. (shrink)

If it seems unquestionable that C. I. Lewis is a Kantian in important respects, it is more difficult to determine what, if anything, is original about his Kantianism. For it might be argued that Lewis’ Kantianism simply reflects an approach to the a priori which was very common in the first half of the twentieth century, namely, the effort to make the a priori relative. In this paper, I will argue that Lewis’ Kantianism does present original features. The latter can (...) be detected by focusing on Lewis’ account of the method of philosophy in the first chapter of Mind and the World Order. In that context, Lewis argues that the method of philosophy should be reflective and critical. It will be my contention that this understanding of philosophy involves a therapeutic perspective, which bears important resemblances to Kant’s account of transcendental reflection in the Amphiboly of the Critique of Pure Reason. I will illustrate how this therapeutic application of reflection works in Lewis’ metaphysics. In this context, reflection can correct errors of reasoning that occur when we are operating within a particular conceptual scheme and use the criteria of reality that are appropriate in another.
