My city and country, so far as I am Antoninus, is Rome; but so far as I am a man, it is the world.

If you commit to philosophy, be prepared at once to be laughed at and made the butt of many snide remarks.

What then can guide a man? One thing and only one, philosophy. But this consists in keeping the daimon within a man free from violence and unharmed, superior to pains and pleasures, doing nothing without a purpose, nor yet falsely and with hypocrisy.

Reflect on the other social roles you play. If you are a council member, consider what a council member should do. If you are young, what does being young mean, if you are old, what does age imply, if you are a father, what does fatherhood entail? Each of our titles, when reflected upon, suggests the acts appropriate to it.

This presumption that you possess knowledge of any use has to be dropped before you approach philosophy – just as if we were enrolling in a school of music or mathematics.

This, then, is the beginning of philosophy – an awareness of one’s own mental fitness.

It stares you in the face. No role is so well suited to philosophy as the one you happen to be in right now.

The work of philosophy is simple and modest. Do not draw me aside into pomposity. 

My advice is really this: what we hear the philosophers saying and what we find in their writings should be applied in our pursuit of the happy life. We should hunt out the helpful pieces of teaching, and the spirited and noble-minded sayings which are capable of immediate practical application – not far-fetched or archaic expressions or extravagant metaphors and figures of speech – and learn them so well that words become works.

Your mind will take the shape of what you frequently hold in thought, for the human spirit is colored by such impressions.

People who are physically ill are unhappy with a doctor who doesn’t give them advice, because they think he has given up on them. Shouldn’t we feel the same towards a philosopher – and assume that he has given up hope of our ever becoming rational – if he will no longer tell us what we need (but may not like) to hear?

Take a good hard look at people’s ruling principle, especially of the wise, what they run away from and what they seek out.

“It’s unfortunate that this has happened”. No. It’s fortunate that this has happened and I’ve remained unharmed by it — not shattered by the present or frightened of the future. It could have happened to anyone. But not everyone could have remained unharmed by it.

The first thing a pretender to philosophy must do is get rid of their presuppositions; a person is not going to undertake to learn anything that they think they already know.

No role is so well suited to philosophy as the one you happen to be in right now.

Life is warfare… Then what can guide us? Only philosophy.

“I know that you, ladies and gentlemen, have a philosophy, each and all of you, and that the most interesting and important thing about you is the way in which it determines the perspective in your several worlds.” 

“There is only one thing a philosopher can be relied upon to do, and that is to contradict other philosophers.” 

“Philosophy lives in words, but truth and fact well up into our lives in ways that exceed verbal formulation.” 

“What a fuss people make about fidelity!" exclaimed Lord Henry. "Why, even in love it is purely a question for physiology. It has nothing to do with our own will. Young men want to be faithful, and are not; old men want to be faithless, and cannot: that is all one can say.” 

“I stand in philosophy exactly where I stand in daily life; I should not be honest otherwise.”

“The hunger for facile wisdom is the root of all false philosophy”

“When we feel the poetic thrill, is it not that we find sweep in the concise and depth in the clear, as we might find all the lights of the sea in the water of a jewel? And what is a philosophic thought but such an epitome?”

“Since the days of Descartes it has been a conception familiar to philosophers that every visible event in nature might be explained by previous visible events, and that all the motions, for instance, of the tongue in speech, or of the hand in painting, might have merely physical causes. If consciousness is thus accessory to life and not essential to it, the race of man might have existed upon the earth and acquired all the arts necessary for its subsistence without possessing a single sensation, idea, or emotion. Natural selection might have secured the survival of those automata which made useful reactions upon their environment. An instinct would have been developed, dangers would have been shunned without being feared, and injuries avenged without being felt.”
