In ancient times, any man rising up above the common people tried to shape his life according to his principles; it is no longer like than now; it is (because) for the ancients, moral was a principle of inner life, whereas in our days, most of the time one is content to adhere to an official moral, that we recognize in theory, but that one does not care to put into practice.
Truths cannot be acquired from words out of other people's mouths. Before Truths can be internalized, they must come from one's own realizations and practices. Through a lifetime of personal practice, human beings are capable of revealing all of the secrets of the cosmic essence. You are your own best judge.
Beneficence is a duty; and he who frequently practices it, and sees his benevolent intentions realized comes, at length, really to love him to whom he has done good.
I never have, above my signature, announced anything that I did not prove first. That is the reason why no statement of mine was ever contradicted, and I do not think it will be, because whenever I publish something I go through it first by experiment, then from experiment I calculate, and when I have the theory and practice meet I announce the results.
Never write about a place until you're away from it, because it gives you perspective. Immediately after you've seen something you can give a photographic description of it and make it accurate. That's good practice, but it isn't creative writing.
A gentleman considers justice to be essential in everything. He practices it according to the principles of propriety. He brings it forth in modesty and faithfully completes it. This is indeed a gentleman.
