He is poor, who has need of another, and has not from himself all things that are useful for life.

Remember, that to change thy mind upon occasion, and to follow him that is able to rectify thee, is equally ingenuous, as to find out at the first, what is right and just, without help. For of thee nothing is required, ti, is beyond the extent of thine own deliberation and jun. merit, and of thine own understanding.

Two kinds of readiness are constantly needed: (i) to do only what the logos of authority and law directs, with the good of human beings in mind; (ii) to reconsider your position, when someone can set you straight or convert you to his. But your conversion should always rest on a conviction that it's right, or benefits others—nothing else. Not because it's more appealing or more popular.

Reason is free from hatred, has no desire to harm anyone or anything, and will never direct you to do evil. Reason works to the benefit of all things.

Have you reason? 'I have.' Then why not use it? If reason does its part, what more would you ask?

What art and profession soever thou hast learned, endeavour to affect it, and comfort thyself in it; and pass the remainder of thy life as one who from his whole heart commits himself and whatsoever belongs unto him, unto the gods: and as for men, carry not thyself either tyrannically or servilely towards any.

By telling you anything at all I'm at least believing in you, I believe you're there, I believe you into being.

I would like to be without shame. I would like to be shameless. I would like to be ignorant. Then I would not know how ignorant I was.

But how can you have a sense of wonder if you're prepared for everything?
