"Whatever work you undertake, do it seriously, thoroughly and well; never leave it half-done or undone, never feel yourself satisfied unless and until you have given it your very best. Cultivate the habits of discipline and toleration. Surrender not the convictions you hold dear but learn to appreciate the points of view of your opponents."

The men who are not interested in philosophy need it most urgently: they are most helplessly in its power. The men who are not interested in philosophy absorb its principles from the cultural atmosphere around them-from schools, colleges, books, magazines, newspapers, movies, television, etc. Who sets the tone of a culture? A small handful of men: the philosophers. Others follow their lead, either by conviction or by default.
