I shall not fear to say that the doctrine of self-interest rightly understood seems to me of all the philosophic theories the most appropriate to the needs of men in our time, and that I see in it the most powerful guarantee against themselves that remains to them. The minds of the moralists of our day ought to turn, therefore, principally toward it. Even should they judge it imperfect, they would still have to adopt it as necessary.

Society will develop a new kind of servitude which covers the surface of society with a network of complicated rules, through which the most original minds and the most energetic characters cannot penetrate. It does not tyrannise but it compresses, enervates, extinguishes, and stupefies a people, till each nation is reduced to nothing better than a flock of timid and industrious animals, of which the government is the shepherd.

Muhammad professed to derive from Heaven, and he has inserted in the Koran, not only a body of religious doctrines, but political maxims, civil and criminal laws, and theories of science. The gospel, on the contrary, only speaks of the general relations of men to God and to each other - beyond which it inculcates and imposes no point of faith. This alone, besides a thousand other reasons, would suffice to prove that the former of these religions will never long predominate in a cultivated and democratic age, whilst the latter is destined to retain its sway at these as at all other periods.

When none but the wealthy had watches, they were almost all very good ones; few are now made which are worth much, but everybody has one in his pocket.

Nothing is more wonderful than the art of being free, but nothing is harder to learn how to use than freedom.

Upon my arrival in the United States the religious aspect of the country was the first thing that struck my attention; and the longer I stayed there, the more I perceived the great political consequences resulting from this new state of things. In France, I had almost always seen the spirit of religion and the spirit of freedom marching in opposite directions. But in America I found they were intimately united and that they reigned in common over the same country.

We succeed in enterprises which demand the positive qualities we possess, but we excel in those which can also make use of our defects.
