There is no man, however wise, who has not at some period of his youth said things, or even lived in a way which was so unpleasant to him in later life that he would gladly, if he could, expunge it from his memory. But he shouldn’t regret this entirely, because he cannot be certain that he has indeed become a wise man – so far as any of us can be wise – unless he has passed through all the fatuous or unwholesome incarnations by which that ultimate stage must be reached. I know there are young people . . . whose teachers have instilled in them a nobility of mind and moral refinement from the very beginning of their schooldays. They perhaps have nothing to retract when they look back upon their lives; they can, if they choose, publish a signed account of everything they have ever said or done; but they are poor creatures, feeble descendants of doctrinaires, and their wisdom is negative and sterile. We cannot be taught wisdom, we have to discover it for ourselves by a journey which no one can undertake for us, an effort which no one can spare us.

There is no man...however wise, who has not at some period in his youth said things, or lived a life, the memory of which is so unpleasant to him that he would gladly expunge it. And yet he ought not entirely to regret it, because he cannot be certain that he has indeed become a wise man...

We do not receive wisdom, we must discover it for ourselves, after a journey through the wilderness which no one else can make for us, which no one can spare us, for our wisdom is the point of view from which we come at last to regard the world. The lives that you admire, the attitudes that seem noble to you, have not been shaped by a paterfamilias or a schoolmaster, they have sprung from very different beginnings, having been influenced by evil or commonplace that prevailed round them. They represent a struggle and a victory.

The life of wisdom is a life of reason. It is important to learn how to think clearly. Clear thinking is not a haphazard enterprise. It requires proper training.

We start trying to be wise when we realize that we are not born knowing how to live, but that life is a skill that has to be acquired,

But my poor Saul, there’s no help for you, you’re heading straight for it. What about all those marvelous people we know, aged about fifty or sixty? Well, there are a few of them…marvelous, mature, wise people. Real people, the phrase is, radiating serenity. And how did they get to be that way? Well, we know, don’t we? Every blood one of them’s got a history of emotional crime, oh the sad bleeding corpses that litter the road to maturity of the wise, serene man or woman of fifty-odd! You simply don’t get to be wise, mature, etc., unless you’ve been a raving cannibal for thirty years or so.

A person of wisdom should be truthful, without arrogance, without deceit, not slanderous and not hateful.

The wise person should go beyond the evil of greed and miserliness.
To have your mind set on calmness, you must take power over sleepiness, drowsiness and lethargy.
There is no place for laziness and no recourse to pride.

Do not be led into lying, do not be attached to forms.
You must see through all pride and fare along without violence.
Do not get excited by what is old, do not be contented with what is new.
Do not grieve for what is lost or be controlled by desire.

Wisdom is the recovery of innocence at the far end of experience

A corroboration of what I have said is the fact, that the young come to be geometricians, and mathematicians, and Scientific in such matters, but it is not thought that a young man can come to be possessed of Practical Wisdom: now the reason is, that this Wisdom has for its object particular facts, which come to be known from experience, which a young man has not because it is produced only by length of time.

Remember, if there is one core teaching at the heart of this philosophy, it’s that we’re not as smart and as wise as we’d like to think we are. If we ever do want to become wise, it comes from the questioning and from humility — not, as many would like to think, from certainty, mistrust, and arrogance.

The wise man does not expose himself needlessly to danger, since there are few things for which he cares sufficiently; but he is willing, in great crises, to give even his life — knowing that under certain conditions it is not worth while to live. He is of a disposition to do men service, though he is ashamed to have a service done to him. To confer a kindness is a mark of superiority; to receive one is a mark of subordination... He does not take part in public displays... He is open in his dislikes and preferences; he talks and acts frankly, because of his contempt for men and things... He is never fired with admiration, since there is nothing great in his eyes. He cannot live in complaisance with others, except it be a friend; complaisance is the characteristic of a slave... He never feels malice, and always forgets and passes over injuries... He is not fond of talking... It is no concern of his that he should be praised, or that others should be blamed. He does not speak evil of others, even of his enemies, unless it be to themselves. His carriage is sedate, his voice deep, his speech measured; he is not given to hurry, for he is concerned about only a few things; he is not prone to vehemence, for he thinks nothing very important. A shrill voice and hasty steps come to a man through care... He bears the accidents of life with dignity and grace, making the best of his circumstances, like a skillful general who marshals his limited forces with the strategy of war... He is his own best friend, and takes delight in privacy whereas the man of no virtue or ability is his own worst enemy, and is afraid of solitude.

And we are wise because we are not so highly educated as to look down upon our laws and customs, and are too rigorously trained in self-control to be able to disobey them. We are trained to avoid being too clever in matters that are of no use – such as being able to produce an excellent theoretical criticism of one’s enemies’ dispositions, and then failing in practice to do quite so well against them. Instead we are taught that there is not a great deal of difference between the way we think and the way others think, and that it is impossible to calculate accurately events that are determined by chance.

There is no one, no matter how wise he is, who has not in his youth said
things or done things that are so unpleasant to recall in later life that
he would expunge them entirely from his memory if that were possible.

Finally, we do become wise, but then it's too late
