I think it’s important to reason from first principles rather than by analogy. The normal way we conduct our lives is we reason by analogy. [With analogy] we are doing this because it’s like something else that was done, or it is like what other people are doing. [With first principles] you boil things down to the most fundamental truths…and then reason up from there.

To live in a state of liberty is not to live apart from law. It is, on the contrary, to live under the highest law, the only law that can really profit a man, the law which is consciously and deliberately imposed by himself on himself.

If there be such a principle as justice, or natural law, it is the principle, or law, that tells us what rights were given to every human being at his birth; what rights are, therefore, inherent in him as a human being, necessarily remain with him during life; and, however capable of being trampled upon, are incapable of being blotted out, extinguished, annihilated, or separated or eliminated from his nature as a human being, or deprived of their inherent authority or obligation.
