To a philosopher, wisdom is not the same as knowledge. Facts may be known in enormous numbers without the knower of them loving wisdom. Indeed, the person who possesses encyclopedic (学识渊博的) information may actually have a genuine contempt (轻视) for those who love and seek wisdom. The philosopher is not content with a mere knowledge of facts. He desires to combine and evaluate facts, and to examine beneath the obvious to the deeper orderliness behind the immediately given facts. Insight into the hidden depths of reality, perspective (洞察) on human life and nature in their entirety, in the words of Plato, to be a spectator of time and existence--these are the philosopher's objectives. Too great an interest in the small details of science, may, and often does, obscure these basic objectives. Philosophers assume that the love of wisdom is a natural gift of the human being. Potentially every man is a philosopher because in the depths of his being there is an intense longing to penetrate to the meaning of the mysteries of existence. The inner deep longing expresses itself in various ways prior to any actual study of philosophy as a technical branch of human culture. Consequently every human being in so far as he has ever been or is a lover of wisdom has, to that extent, a philosophy of life. The title below that best expresses the idea of this passage is ______.
