Liberty is the harmony between the will and the law.

The history of institutions is often a history of deception and illusions; for their virtue depends on the ideas that produce and on the spirit that preserves them, and the form may remain unaltered when the substance has passed away.

History, to be above evasion or dispute, must stand on documents, not on opinions.

Be not content with the best book; seek sidelights from the others; have no favourites.

Property is not the sacred right. When a rich man becomes poor it is a misfortune, it is not a moral evil. When a poor man becomes destitute, it is a moral evil, teeming with consequences and injurious to society and morality.

Monarchy hardens into despotism. Aristocracy contracts into oligarchy. Democracy expands into the supremacy of numbers.

Good and evil lie close together. Seek no artistic unity in character.
