Of all studies, the one he would rather have avoided was that of his own mind. He knew no tragedy so heartrending as introspection. - Henry Adams

The result might have been stated in a mathematical formula as early as the time of Archimedes, six hundred years before Rome fell. The economic needs of a violently centralizing society forced the empire to enlarge its slave-system until the slave-system consumed itself and the empire too, leaving society no resource but further enlargement of its religious system in order to compensate for the losses and horrors of the failure. For a vicious circle, its mathematical completeness approached perfection. The dynamic law of attraction and reaction needed only a Newton to fix it in algebraic form. At last, in 410, Alaric sacked Rome, and the slave-ridden, agricultural, uncommercial Western Empire — the poorer and less Christianized half — went to pieces.

Paris remained Parisian in spite of change, mistress of herself though China fell. Scores of artists — sculptors and painters, poets and dramatists, workers in gems and metals, designers in stuffs and furniture — hundreds of chemists, physicists, even philosophers, philologists, physicians, and historians — were at work, a thousand times as actively as ever before, and the mass and originality of their product would have swamped any previous age, as it very nearly swamped its own; but the effect was one of chaos, and Adams stood as helpless before it as before the chaos of New York.

Any woman would see at once the secret of all this ingenuity and effort. The Chartres apse, enormous in size and width, is exquisitely lighted. Here, as everywhere throughout the church, the windows give the law, but here they actually take place of law.
