>Since the man of common sense makes his appeal to feeling, to an oracle within his breast, he is finished and done with anyone who does not agree; he only has to explain that he has nothing more to say to anyone who does not find and feel the same in himself. In other words, he tramples underfoot the roots of humanity. For it is in the nature of humanity to press onward to agreement with others; human nature only really exists in an achieved community of minds.
