The purpose of Plato, or of Aristotle, as Fārābī conceived of it, is sufficiently revealed in this seemingly conventional praise of philosophy. - Leo Strauss

Liberal education, which consists in the constant intercourse with the greatest minds, is a training in the highest form of modesty. … It is at the same time a training in boldness. … It demands from us the boldness implied in the resolve to regard the accepted views as mere opinions, or to regard the average opinions as extreme opinions which are at least as likely to be wrong as the most strange or least popular opinions

Every human being and every society is what it is by virtue of the highest to which it looks up. The city, if it is healthy, looks up, not to the laws which it can unmake as it made them, but to the unwritten laws, the divine law, the gods of the city. The city must transcend itself. ...the most important consideration concerns that which transcends the city or which is higher than the city; it does not concern things which are simply subordinate to the city.

Men are constantly attracted and deluded by two opposite charms: the charm of competence which is engendered by mathematics and everything akin to mathematics, and the charm of humble awe, which is engendered by meditation on the human soul and its experiences. Philosophy is characterized by the gentle, if firm, refusal to succumb to either charm. It is the highest form of the mating of courage and moderation. In spite of its highness or nobility, it could appear as Sisyphean or ugly, when one contrasts its achievement with its goal. Yet it is necessarily accompanied, sustained and elevated by eros. It is graced by nature's grace.
