I want to know the answer to the following question:
Who censured Kant for his agnostic tautology?
All the background I'm provided with is that "Friedrich Nietzsche argued that Kant commits an agnostic tautology and does not offer a satisfactory answer as to the source of a philosophical right to such-or-other metaphysical claims; he ridicules his pride in tackling "the most difficult thing that could ever be undertaken on behalf of metaphysics.". Is that enough to answer the question?
