“Moral law is an invention of mankind for the disenfranchisement of the powerful in favor of the weak. Historical law subverts it at every turn. A moral view can never be proven right or wrong by any ultimate test. A man falling dead in a duel is not thought thereby to be proven in error as to his views. His very involvement in such a trial gives evidence of a new and broader view.”

Passages from the Life of a Philosopher (1864)
Context: In the works of the Creator ever open to our examination, we possess a firm basis on which to raise the superstructure of an enlightened creed. The more man inquires into the laws which regulate the material universe, the more he is convinced that all its varied forms arise from the action of a few simple principles. These principles themselves converge, with accelerating force, towards some still more comprehensive law to which all matter seems to be submitted. Simple as that law may possibly be, it must be remembered that it is only one amongst an infinite number of simple laws: that each of these laws has consequences at least as extensive as the existing one, and therefore that the Creator who selected the present law must have foreseen the consequences of all other laws. The works of the Creator, ever present to our senses, give a living and perpetual testimony of his power and goodness far surpassing any evidence transmitted through human testimony. The testimony of man becomes fainter at every stage of transmission, whilst each new inquiry into the works of the Almighty gives to us more exalted views of his wisdom, his goodness, and his power.

Context: This freedom of communication is indispensable for the development and extension of scientific knowledge, a consideration of much practical import. In the first instance it must be guaranteed by law. But laws alone cannot secure freedom of expression; in order that every man may present his views without penalty there must be a spirit of tolerance in the entire population. Such an ideal of external liberty can never be fully attained but must be sought unremittingly if scientific thought, and philosophical and creative thinking in general, are to be advanced as far as possible.

Original text:
Les meilleures lois ne peuvent faire marcher une constitution en dépit des mœurs ; les mœurs tirent parti des pires lois. C'est là une vérité commune, mais à laquelle mes études me ramènent sans cesse. Elle est placée dans mon esprit comme un point central. Je l'aperçois au bout de toutes mes idées.
1830s
Context: The best laws cannot make a constitution work in spite of morals; morals can turn the worst laws to advantage. That is a commonplace truth, but one to which my studies are always bringing me back. It is the central point in my conception. I see it at the end of all my reflections.
