America's skyscrapers were not built by public funds nor for a public purpose: they were built by the energy, initiative and wealth of private individuals for personal profit.

The Middle Ages were an era of mysticism, ruled by blind faith and blind obedience to the dogma that faith is superior to reason. The Renaissance was specifically the rebirth of reason, the liberation of man's mind, the triumph of rationality over mysticism - a faltering, incomplete, but impassioned triumph that led to the birth of science, of individualism, of freedom.

If you're good, that's no achievement of yours - you were lucky in your glands. If you're rotten, nobody should punish you - you were unlucky, that's all.
