The substance of Searle's criticism of Derrida in relation to topics in the philosophy of language—referenced in Derrida's "Signature Event Context"—was that Derrida had no apparent familiarity with contemporary philosophy of language nor of contemporary linguistics in Anglo-Saxon countries. Searle explains, "When Derrida writes about the philosophy of language he refers typically to Rousseau and Condillac, not to mention Plato. And his idea of a "modern linguist" is Benveniste or even Saussure." Searle describes Derrida's philosophical knowledge as pre-Wittgensteinian—that is to say, disconnected from analytic tradition—and consequently, in his perspective, naive and misguided, concerned with issues long-since resolved or otherwise found to be "non"-issues.
