BRENTANO'S APPROPRIATION OF THE Scholastic notion of intentionality, and of what Brentano called "the intentional (or mental) inexistence of an object," was early on exploited in a reading of Kant's theory of objects and appearances. Apparently the first systematic attempt was undertaken by Hans Vaihinger. However, Vaihinger's is radically different from more recent intentionalist readings of Kant. Albeit not in every respect, I propose that a return to this aspect of Vaihinger's approach supports a rewarding advance on such readings. After a general introduction, I survey three instances of the latter—Prauss, Pereboom, and Sellars—in section 2 (and comment on some others in notes throughout). In sections 3 and 4, I then turn to Vaihinger's approach.

This book is a critical and analytical survey of the major attempts, in modern philosophy, to deal with the phenomenon of intentionality—those of Descartes, Brentano, Meinong, Husserl, Frege, Russell, Bergmann, Chisholm, and Sellars. By coordinating the semantical approaches to the phenomenon, Dr. Aquila undertakes to provide a basis for dialogue among philosophers of different persuasions. "Intentionality" has become, since Franz Brentano revived its original medieval use, the standard term describing the mind's apparently paradoxical capacity to relate itself to objects existing in the world. One approach to the phenomenon emphasizes the mental act. The author argues that the most adequate account involves elements of both approaches. Contemporary treatments tend to formulate problems of intentionality primarily in terms of logic and semantics rather than those of metaphysics and phenomenology. Dr. Aquila's effort to coordinate these approaches will make his book useful to students both of analytical philosophy of mind and also of phenomenology.

I want to state as clearly as I can the sense in which Kant is, and the sense in which he is not, a phenomenalist. And I also want to state the argument which Kant presents, in the Transcendental Deduction, for his particular version of phenomenalism. Since that doctrine has been stated by Kant himself as the view that we have knowledge of “appearances” only, and not of things in themselves, or that material objects are nothing but a species of our “representations,” it will of course be part of my task in this paper to deal with these fundamental notions. Some recent works on Kant have completely misinterpreted these notions, and because of this they have failed to capture the peculiar character of Kant’s phenomenalism. Jonathan Bennett, for example, interprets Kant’s claim that “objects are nothing but representations” as the claim that “statements about objects must be translatable into statements about intuitions.” I shall call such a view a reductive phenomenalism and argue in this paper that Kant is not a reductive phenomenalist. But Kant is, all the same, a phenomenalist. I shall call him an existential phenomenalist. The difference is this: Kant does not maintain, as Bennett claims, that all propositions which assert or presuppose the existence of objects must be translatable into statements which refer to intuitions alone, but he does hold that all such propositions are translatable into statements about the existence of intuitions alone. When Kant tells us, therefore, that objects are mere “appearances,” he is not offering a theory about what empirical objects are or about what we are really referring to when we refer to such objects, but he is offering a theory about the sense in which any empirical objects can meaningfully be said to exist. The significance of the distinction between reductive and existential phenomenalism is great. For it both allows Kant to do justice to those considerations which appear to lead to idealism or phenomenalism, while it does not at the same time require him to deny that the level at which we speak of material bodies and states is, and must be, a basic level of our conceptual framework. It cannot be one which is itself built upon, or constructed out of, some more basic level, e.g., out of talk about sense-data or sensory states. The uniqueness of Kant’s phenomenalism lies precisely at this point.
