Critique Of Pure Reason

Kant'sCritique of Pure Reasoncontains an original and powerful semantics of singular cognitive reference which has important implications for epistemology and for philosophy of science. Here I argue that Kant's semantics directly and strongly supports Newton's Rule 4 of (natural) Philosophy in ways which support Newton's realism about gravitational force. I begin with Newton's Rule 4 of Philosophy and its role in Newton's justification of realism about gravitational force (§II). Next I briefly summarize Kant's semantics of singular cognitive reference (§III). I then show that the key point of Kant's cognitive semantics is embedded in and strongly supports Newton's Rule 4, and that it rules out not only Cartesian physics (perHarper) but also Cartesian, infallibilist presumptions about empirical justification generally (§IV). Finally, I argue that Kant's semantics reveals a key defect in the original version of Bas van Fraassen's anti-realist ‘Constructive Empiricism’, and in many common objections to realism (§V). Fortunately, Kant's semantics of singular cognitive reference stands independently of his Transcendental Idealism; nothing I argue in this paper depends at all upon that doctrine.In experimental philosophy, propositions gathered from phenomena by induction should be considered either exactly or very nearly true notwithstanding any contrary hypotheses, until yet other phenomena make such propositions either more exact or liable to exceptions. (Newton 1999: 796)

AbstractKant’s Critique of Pure Reason contains an original and powerful semantics of singular, specifically cognitive reference which has important implications for epistemology and for philosophy of science (and which is entirely independent of Transcendental Idealism). Here I argue that Kant’s cognitive semantics directly and strongly supports Newton’s Rule 4 of Experimental Philosophy in ways which support Newton’s realism about gravitational force. I begin with Newton’s Rule 4 and its role in Newton’s justification of realism about gravitational force (§ 1). I then briefly summarize Kant’s semantics of singular cognitive reference (§ 2), and show that it is embedded in, and strongly supports, Newton’s Rule 4, and that it rules out not only Cartesian physics (per Harper) but also Cartesian, infallibilist presumptions about empirical justification generally (§ 3). This result exposes a key fallacy in Bas van Fraassen’s main argument for his anti-realist Constructive Empiricism, and in many common objections to realism (§ 4). These problems reveal yet a further important regard in which Constructive Empiricism is not (so to speak) ‘empirically’ adequate, not even to Classical Newtonian Mechanics (§ 5). This inadequacy of Constructive Empiricism highlights a chronic empiricist misunderstanding of Newton’s mechanics (§ 6). Finally, Kant’s cognitive semantics improves upon the semantic interpretation of scientific theories, and rectifies the presumption that laws of physics literally ‘lie’ (§ 7). Thus Kant and Newton still have invaluable lessons for contemporary philosophy and history of science (§ 8).

Transcendental Illusion

AbstractKant makes two claims in the Critique of Pure Reason that anticipate concerns of twentieth-century philosophy of science. The first, that the understanding and sensibility are constitutive of knowledge, while reason is responsible for transcendental illusion, amounts to his solution to Karl Popper’s “problem” of demarcating science from pseudoscience. The second, that besides these constitutive roles of the understanding and sensibility, reason is itself needed to discover new empirical knowledge, anticipates Hans Reichenbach’s distinction between the “contexts” of justification and discovery. Unlike Reichenbach, however, who thinks that there can be a “logic” only of justification, Kant provides what amounts to a logic of discovery. Though Kant’s broader concerns are not Popper’s or Reichenbach’s, using theirs as framing devices reveals two otherwise unnoticed things about the Critique of Pure Reason. First, besides its general epistemological and metaphysical aims, the Critique lays groundwork for the twentieth century’s specialized field of the philosophy of science. Second, Kant’s solution to the demarcation problem contradicts his logic of discovery, so in this instance the Critique is too ambitious.

My topic is historical rather than philosophical. I want to consider what Kant aimed to achieve in the Critique of Pure Reason. In 1909 Prichard wrote, “Kant's problem is similar to Locke's. Locke states that his purpose is to inquire into the original, certainty, and extent of human knowledge.” Many have maintained that Kant's purpose was to mediate between rationalism and empiricism in epistemology. Hermann Cohen held that the aim of the Critique is to provide a theory of experience, an account of empirical knowledge. Ernst Cassirer and other neo-Kantians have held that its aim is to furnish a philosophy of science.

Ensemble Interpretation

Two conceptions of the contemporary philosophy of science are taken under consideration: scientific realism and constructive empiricism. Scientific realism presupposes 1) the conception of truth as the correspondence of knowledge to reality, 2) the real existence of entities postulated by a theory. The constructive empiricism puts forward the idea of empirical adequacy: science aims to give us the theories which are empirically adequate and acceptance of the theory involves as belief only that it is empirically adequate. To compare methodological resources of these two positions in the philosophy of science the problem of the interpretation of quantum mechanics is involved. As a methodological realization of scientific realism the ensemble interpretation of quantum mechanics is taken under consideration. K.Popper’s version

Age Of Enlightenment

In his famous essay from 1784, Kant denied that we "live in an enlightened age"; yet he claimed that we "live in an age of enlightenment". If we should answer the question if we live in an enlightened age now, we could basically give the same answer. The enlightenment as an ongoing process can be found throughout Kant's whole work. This article focuses on how the concept of enlightenment can be applied to the Kantian psychology, which marks an important change of theory of the soul within modern western metaphysics. Kant's idea of enlightenment and 'critique' will be illustrated with reference to the "Paralogisms" of the Critique of Pure Reason. Finally, an analysis of some passages of the "Paralogisms" shall demonstrate that Kant's critique of the previous metaphysical doctrine of the human soul should not be understood as a complete rejection of this doctrine; rather, Kant's critique of what is called rational psychology should be understood as a critical transformation.

Material Condition

In the Postulates of Empirical Thinking, a section of the Critique of Pure Reason, Kant presents an account of the content and role of our concept of real possibility in terms of formal conditions of experience. However, much later in the Critique he introduces the idea of a material condition of possibility. What is this material condition of possibility, and how does it fit with the conception of possibility in terms of formal conditions? This essay argues that the key to answering these questions—as well as to understanding Kant’s criticism of rational theology, in which the discussion of the material condition of possibility appears—is Kant’s account of how we can individuate objects.

This brief chapter summarizes central findings regarding the role of parenthetical sentences in practical discourse. But it also provides historical context. It suggests that a precursor of parentheticalism may be found in Kant, especially in Kant’s views about the “I think,” especially as they are expressed in the B-Version of the “Transcendental Deduction” and the B-Version of the chapter on Paralogisms in the Critique of Pure Reason.
