Abstract

Many philosophers have been suspicious of any “transcendental argument”. In the literature concerned with arguments such as Kant’s Transcendental Deduction, or the “private language” or “other minds” argument, there have been frequent charges that such attempts are “impossible,” spurious, or, even more frequently, incomplete, that their success depends on some controversial philosophical position, such as verificationism. A recent addition to the latter kind of charge is that a successful TA must involve a commitment to some form of idealism. This is, prima facie, quite a reasonable suspicion. Any argument about the necessary conditions of our belief can tell us something about objects in the world, it would seem, only if it can also be shown that the existence of such objects depends on our beliefs. Moreover, Kant, the originator of the modern form of antiskeptical TA’s, was also a famous idealist, adding to the suspicion. Bernard Williams has argued for this connection in recent articles on Wittgenstein and Shoemaker, and more recently, Ross Harrison, in “Transcendental Arguments and Idealism,” has tried to deny that there is such a connection and to argue that there can be a successful TA without any commitment to idealism. There may be some form of a TA that is nonidealistic, but an examination of Harrison’s case will reveal, I think, not only that he has not discovered such an argument, but that it is unlikely that there could be such a TA, except in trivial cases. Moreover, I also want to show that a consideration of his argument can be of help in discovering what kind of idealism is or is not involved in TA’s, especially in Kant, and what problems are apparent in that version of idealism.
