…he did not want to do away with his scepticism, precisely because he wanted to doubt. That is his prerogative. But one should not attribute to him the stupidity that he believed one doubted with necessity, or by the same token what is even dumber, that if such were the case, doubt could be abolished. The Greek sceptic does not deny the correctness of sensation and immediate cognition. Error, he says, has a completely different source; it comes from the inferences I draw. If I can just refrain from drawing any inferences, then I will never be deceived.
—Kierkegaard (Philosophical Crumbs, trans. M.G. Piety, p. 149)
