It is easy to understand that if an individual is interested in his fellows and in the welfare of mankind, everything he does will be guided by the interests of his fellows, and he will try to solve the problem of love and marriage as if the welfare of others were involved. He does not need to know that he is trying to solve it in this way. If you ask him, he will perhaps be unable to give a scientific account of his aims. But he will spontaneously seek the welfare and improvement of mankind and this interest will be visible in all his activities.
