The science of politics is the one science that is deposited by the streams of history, like the grains of gold in the sand of a river; and the knowledge of the past, the record of truths revealed by experience, is eminently practical, as an instrument of action and a power that goes to making the future.

It is they [men of science] who hold the secret of the mysterious property of the mind by which error ministers to truth, and truth slowly but irrevocably prevails. Theirs is the logic of discovery, the demonstration of the advance of knowledge and the development of ideas, which as the earthly wants and passions of men remain almost unchanged, are the charter of progress, and the vital spark in history.

The passion for power over others can never cease to threaten mankind, and is always sure of finding new and unforseen allies in continuing its martyrology.

It is easier to find people fit to govern themselves than people fit to govern others.

Do not turn yourself from an end into a means-one does not justify the other.

For centuries it was never discovered that education was a function of the State, and the State never attempted to educate. But when modern absolutism arose, it laid claim to everything on behalf of the sovereign power....When the revolutionary theory of government began to prevail, and Church and State found that they were educating for opposite ends and in a contradictory spirit, it became necessary to remove children entirely from the influence of religion.

At all times sincere friends of freedom have been rare, and its triumphs have been due to minorities, that have prevailed by associating themselves with auxiliaries whose objects often differed from their own; and this association, which is always dangerous, has sometimes been disastrous.
