If ideas do not determine history, inventions do; and inventions are determined by ideas. - Will Durant

but now and then liberty, in the slogans of the strong, means freedom from restraint in the exploitation of the weak.

Every science begins as philosophy and ends as art; it arises in hypothesis and flows into achievement.

History is, above all else, the creation and recording of that heritage; progress is its increasing abundance, preservation, transmission, and use. To those of us who study history not merely as a warning reminder of man’s follies and crimes, but also as an encouraging remembrance of generative souls, the past ceases to be a depressing chamber of horrors; it becomes a celestial city, a spacious country of the mind, wherein a thousand saints, statesmen, inventors, scientists, poets, artists, musicians, lovers, and philosophers still live and speak, teach and carve and sing. The historian will not mourn because he can see no meaning in human existence except that which man puts into it; let it be our pride that we ourselves may put meaning into our lives, and sometimes a significance that transcends death. If a man is fortunate he will, before he dies, gather up as much as he can of his civilized heritage and transmit it to his children. And to his final breath he will be grateful for this inexhaustible legacy, knowing that it is our nourishing mother and our lasting life.
