“Nothing, to my way of thinking, is a better proof of a well ordered mind than a man’s ability to stop just where he is and pass some time in his own company.”

“Philosophy does not promise to secure anything external for man, otherwise it would be admitting something that lies beyond its proper subject-matter. For as the material of the carpenter is wood, and that of statuary bronze, so the subject-matter of the art of living is each person’s own life.”

“From the philosopher Catulus, never to be dismissive of a friend’s accusation, even if it seems unreasonable, but to make every effort to restore the relationship to its normal condition.”

“The first and most important field of philosophy is the application of principles such as “Do not lie.” Next come the proofs, such as why we should not lie. The third field supports and articulates the proofs, by asking, for example, “How does this prove it? What exactly is a proof, what is logical inference, what is contradiction, what is truth, what is falsehood?” Thus, the third field is necessary because of the second, and the second because of the first. The most important, though, the one that should occupy most of our time, is the first. But we do just the opposite. We are preoccupied with the third field and give that all our attention, passing the first by altogether. The result is that we lie – but have no difficulty proving why we shouldn’t.”

“If you want to make progress, put up with being perceived as ignorant or naive in worldly matters, don’t aspire to a reputation for sagacity. If you do impress others as somebody, don’t altogether believe it. You have to realize, it isn’t easy to keep your will in agreement with nature, as well as externals. Caring about the one inevitably means you are going to shortchange the other.”

“Remember to act always as if you were at a symposium. When the food or drink comes around, reach out and take some politely; if it passes you by don’t try pulling it back. And if it has not reached you yet, don’t let your desire run ahead of you, be patient until your turn comes. Adopt a similar attitude with regard to children, wife, wealth and status, and in time, you will be entitled to dine with the gods. Go further and decline these goods even when they are on offer and you will have a share in the gods’ power as well as their company. That is how Diogenes, Heraclitus and philosophers like them came to be called, and considered, divine.”

“What really frightens and dismays us is not external events themselves, but the way in which we think about them. It is not things that disturb us, but our interpretation of their significance.”

“Remember, it is not enough to be hit or insulted to be harmed, you must believe that you are being harmed. If someone succeeds in provoking you, realize that your mind is complicit in the provocation. Which is why it is essential that we not respond impulsively to impressions; take a moment before reacting, and you will find it easier to maintain control.”

“Until we have begun to go without them, we fail to realize how unnecessary many things are. We’ve been using them not because we needed them but because we had them.”

“Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.”

“Life is such unutterable hell, solely because it is sometimes beautiful. If we could only be miserable all the time, if there could be no such things as love or beauty or faith or hope, if I could be absolutely certain that my love would never be returned: how much more simple life would be. One could plod through the Siberian salt mines of existence without being bothered about happiness. Unfortunately the happiness is there. There is always the chance (about eight hundred and fifty to one) that another heart will come to mine. I can’t help hoping, and keeping faith, and loving beauty. Quite frequently I am not so miserable as it would be wise to be.”
