All I have to say is, Love one another - that is the height of all philosophy. It is beyond all religions. It is the secret of joy - the fountain of Perpetual Youth - the only rainbow on life's dark cloud.
This, in my judgment, is the highest philosophy: First, do not regret having lost yesterday; second, do not fear that you will lose tomorrow; third, enjoy today.
The old man has been long at the fair. He is acquainted with the jugglers at the booths. His curiosity has been satisfied. He no longer cares for the exceptional, the monstrous, the marvelous and deformed. He looks through and beyond the gilding, the glitter and gloss, not only of things, but of conduct, of manners, theories, religions and philosophies. He sees clearer. The light no longer shines in his eyes.
When passions and appetites are stronger than the intellect, men are savages; when the intellect governs the passions, when the passions are servants, men are civilized. The people need education - facts - philosophy.
The church in all ages and among all peoples has been the consistent enemy of the human race. Everywhere and at all times, it has opposed the liberty of thought and expression. It has been the sworn enemy of investigation and intellectual development. It has denied the existence of facts, the tendency of which was to undermine its power. It has always been carrying fagots to the feet of Philosophy. It has erected the gallows for Genius. It has built the dungeon for Thinkers.
Years should not be devoted to the acquisition of dead languages or to the study of history which, for the most part, is a detailed account of things that never occurred. It is useless to fill the individual with dates of great battles, with the births and deaths of kings. They should be taught the philosophy of history, the growth of nations, of philosophies, theories, and, above all, of the sciences.
It is like most other ancient books - a mingling of falsehood and truth, of philosophy and folly - all written by men, and most of the men only partially civilized. Some of its laws are good - some infinitely barbarous. None of the miracles related were performed. . . . Take out the absurdities, the miracles, all that pertains to the supernatural - all the cruel and barbaric laws - and to the remainder I have no objection. Neither would I have for it any great admiration.
