"Derrida’s special significance lies not in the fact that he was subversive, but in the fact that he was an outright intellectual fraud -- and that he managed to dupe a startling number of highly educated people into believing that he was onto something. […] whatever Derrida is affirming he is also simultaneously denying. From a logical perspective, the only way to read Derrida on his own terms is mentally to insert the phrase “or not” after every one of his statements."
January 1, 1970
