It is the ideal which prompts man to sacrifice, and the most important thing he can sacrifice is his own life. A man without ideal has no depth, he is shallow. However pleased he may be with his everyday life, he can never enjoy that happiness which is independent of outer circumstances. The pleasure which is experienced through pain is the pleasure experienced by the idealist. But what of the pleasure that has not come out of pain? It is tasteless. Life's gain, which people think so much of, what is it after all? A loss caused by an ideal is a greater gain than any other gain in this world.
