It also bears mentioning that, in the pages of the festschrift dedicated to him, Frankfurt does comment on Cohen's critique. He does so with impressive philosophical rigor - and with still more admirable good grace. "If I am reluctant to endorse Cohen's claim that the sort of bullshit on which my attention was focused 'is just one flower in the lush garden of bullshit,' " he writes, "it is not because I doubt his claim is true. It is only because I cannot help recalling that bullshit is an animal product and not a plant."
