What do you think of Spinoza? For me he is the ideal example of the cosmic man. He worked as an obscure diamond cutter, disdaining fame and a place at the table of the great. He tells us the importance of understanding our emotions and suggests what causes them. Man will never be free until he is able to direct his emotions to think clearly. Only then can he control his environment and preserve his energy for creative work.
