The average man feels, not without some justification, that as writers, philosophers are often painfully obscure and even deliberately perverse. In his essay “On Philosophical Style” Professor Brand Blanshard agrees that all too often these charges are true. He notes, for instance, Lord Macaulay’s complaint that he found Kant’s Critique “utterly unintelligible” (a criticism Mr. Blanshard substantiates by exhibiting a typical Kantian sentence).
