Windfalls.

The men of letters who have rendered the greatest services to the small number of thinking beings spread over the world, are the isolated writers, the true scholars shut in their studies, who have neither argued on the benches of the universities, nor told half-truths in the academies; and almost all of them have been persecuted. Our wretched species is so made that those who walk on the well-trodden path always throw stones at those who are showing a new road.

Voltaire, from Voltaire's Philosophical Dictionary
