" To the uninitiated they have merely murmured, with a pitying smile and a wave of the hand: What! are you still troubled by that? Or if compelled to be so scholastic as to labour the point they have explained, as usual, that oneself cannot be the absolute because the idea of oneself, to arise, must be contrasted with other ideas. Therefore, you cannot well have the idea of a world in which nothing appears but the idea of yourself. "
