In this manner man begins to find out the truth. When his heart is awakened by despairs he sees that the end of his spells and changes of life is heart breaking. He then becomes a philosopher. Philosophy is not learned from books but it comes from experience. When the heart is broken by finding itself dependent on environment, people and affairs of life, it realizes that these were inconstant, and that which it hoped to accomplish has not come to pass. Then man becomes a philosopher.
