Abstract
Peirce's response to the anti-metaphysical positivism of his day draws on Kant's response to Hume, but moves beyond it, being thus a valuable resource, especially in our own post-Logical Positivist era. (Part of) Kant's legacy to Peirce was a lasting conviction that metaphysics need not be the hopelessly "airy science" Hume had pooh-poohed, but could and should become a legitimate and valuable area of investigation. (Part of) Peirce's legacy to philosophy today is a distinctively plausible post-Kantian reconstruction of how this might be achieved.
