The mastery of philosophy will produce a supreme self-confidence within him throughout his dealings with life. The man who knows nothing of philosophy will declare that it has nothing to do with practical affairs and that it will not help you to rise in your chosen career, for instance. He is wrong. Philosophy gives its votary a thoroughly scientific and practical outlook whilst it enables him to solve his problems unemotionally and by the clear light of reason. He will, however, be under certain ethical limitations from which other men are exempt, for he takes the game of living as a sacred trust and not as a means for personal aggrandizement at the expense of others.
