I begin by taking. I shall find scholars later to demonstrate my perfect right. - Frederick II of Prussia

I wanted to have a water jet in my garden: Euler calculated the force of the wheels necessary to raise the water to a reservoir, from where it should fall back through channels, finally spurting out in Sans Souci. My mill was carried out geometrically and could not raise a mouthful of water closer than fifty paces from the reservoir. Vanity of vanities! Vanity of geometry!

Compare Holland with Russia; you see only marshy and sterile islands in the former, which rise from the center of the ocean: a small republic which is only 48 miles length by 40 wide. But this small body is the very nerve-center of the region: immense people live in it, and these industrious people are both powerful and rich. They shook the yoke of the Spanish domination, which was then the most formidable monarchy of Europe. The trade of this republic extends to the ends of the world; and new trade appears almost immediately; it can maintain in times of war an army fifty thousand men, without counting a many and well maintained fleet.

If the men were without passions, it would be forgivable to see Machiavel try to give some to them; he would be the new Prometheus bringing celestial fire to breathe life into robots. But no man is without passions. When they are moderated, they are the heart of the enterprise; but when the brake is stripped of them, they are its destruction.
