How, then, can he call it an ‘apology’? Montaigne’s trick is simple. He purports to defend Sebond against those who have tried to bring him down using rational arguments. He does this by showing that rational arguments, in general, are fallible, because human reason itself cannot be relied on. Thus he defends a rationalist against other rationalists by arguing that anything based on reason is valueless. Montaigne’s defence undermines Sebond’s enemies, all right, but it undermines Sebond himself even more fatally. Of this, he was obviously well aware.
