My History of the Jesuits is in four volumes.... This society has been a greater calamity to mankind than the French Revolution, or Napoleon's despotism or ideology. It has obstructed progress of reformation and the improvement of the human mind in society much longer and more fatally.

I must study Politicks and War that my sons may have liberty to study Mathematicks and Philosophy. My sons ought to study Mathematicks and Philosophy, Geography, natural History, Naval Architecture, navigation, Commerce and Agriculture, in order to give their Children a right to study Painting, Poetry, Musick, Architecture, Statuary, Tapestry and Porcelaine. (12 May 1780)

The proposition that the people are the best keepers of their own liberties is not true. They are the worst conceivable, they are no keepers at all; they can neither judge, act, think, or will, as a political body.

Children should be educated and instructed in the principles of freedom. Aristotle speaks plainly to this purpose, saying, 'that the institution of youth should be accommodated to that form of government under which they live; forasmuch as it makes exceedingly for the preservation of the present government, whatsoever it be.

The arts and sciences, in general, during the three or four last centuries, have had a regular course of progressive improvement. The inventions in mechanic arts, the discoveries in natural philosophy, navigation and commerce, and the advancement of civilization and humanity, have occasioned changes in the condition of the world and the human character which would have astonished the most refined nations of antiquity. A continuation of similar exertions is everyday rendering Europe more and more like one community, or single family.

It should be your care, therefore, and mine, to elevate the minds of our children and exalt their courage; to accelerate and animate their industry and activity; to excite in them an habitual contempt of meanness, abhorrence of injustice and inhumanity, and an ambition to excel in every capacity, faculty, and virtue. If we suffer their minds to grovel and creep in infancy, they will grovel all their lives.
