"Derrida’s claim is that all philosophising is infected with a blindness to the metaphoricity of the language in which it is expressed. Metaphor is more than a special effect within language; it is the very essence of language. Even a philosophy of metaphor is itself inescapably metaphorical, so that metaphor cannot be adequately defined outside its own system. Metaphor thus runs out of control through language and through philosophy, the whole of philosophical discourse being an edifice built entirely upon itself without grounding in reality, and sustaining itself by an active forgetting of this fact."
— Karl Simms on Jacques Derrida’s “White Mythologies”
