Plato

["F]or it's not possible," [Socrates] said, "for anybody to experience a greater evil than hating arguments. Hatred of arguments and hatred of human beings come about in the same way. For hatred of human beings arises from artlessly trusting somebody to excess, and believing that human being to be in every way true and sound and trustworthy, and then a little later discovering that this person is wicked and untrustworthy - and then having this experience again with another. And whenever somebody experiences this many times, and especially at the hands of just those he might regard as his most intimate friends and comrades, he then ends up taking offense all the time and hates all human beings and believes there's nothing at all sound in anybody.

[W]hen men have both done and suffered injustice and have had experience of both, not being able to avoid the one and obtain the other, they think that they had better agree among themselves to have neither; hence there arise laws and mutual covenants; and that which is ordained by law is termed by them lawful and just. This they affirm to be the origin and nature of justice;__t is a mean or compromise,between the best of all, which is to do injustice and not be punished, and the worst of all, which is to suffer injustice without the power of retaliation; and justice, being at a middle point between the two, is tolerated not as a good, but as the lesser evil_

There is nothing which for my part I like better, Cephalus, than conversing with aged men; for I regard them as travellers who have gone a journey which I too may have to go, and of whom I ought to inquire, whether the way is smooth and easy, or rugged and difficult.

And yet even in reaching for the beautiful there is beauty, and also in suffering whatever it is that one suffers en route.

Be kind, because everyone is having a really hard time.

A dog has the soul of a philosopher.

Be kind, for everyone you meet is fighting a harder battle.

What is honored in a culture gets cultivated there.

The Muse herself makes some men inspired, from whom a chain of other men is strung out who catch their own inspiration from theirs.

You're my Star, a stargazer too,and I wish that I were Heaven,with a billion eyes to look at you!

...and when one of them meets the other half, the actual half of himself, whether he be a lover of youth or a lover of another sort, the pair are lost in an amazement of love and friendship and intimacy and one will not be out of the other's sight, as I may say, even for a moment...

The man who makes everything that leads to happiness depends upon himself, and not upon other men, has adopted the very best plan for living happily. This is the man of moderation, the man of manly character and of wisdom.

No matter how hard you fight the darkness, every light casts a shadow, and the closer you get to the light, the darker that shadow becomes.

Light is the shadow of god

Education isn't what some people declare it to be, namely, putting knowledge into souls that lack it, like putting sight into blind eyes...The power to learn is present in everyone's soul and...the instrument with which each learns is like an eye that cannot be turned around from darkness to light without turning the whole body... Then education is the craft concerned with doing this very thing, this turning around, and with how the soul can most easily and effectively be made to do it. it isn't the craft of putting sight into the soul. Education take for granted that sight is there but that it isn't turned the right way or looking where it ought to look, and it tries to redirect it appropriately.

Because a freeman ought not to be a slave in the acquisition of knowledge of any kind. Bodily exercise, when compulsory, does no harm to the body; but knowledge which is acquired under compulsion obtains no hold on the mind.

Wise men talk because they have something to say; Fools, because they have to say something.

I thought to myself: I am wiser than this man; neither of us probably knows anything that is really good, but he thinks he has knowledge, when he has not, while I, having no knowledge, do not think I have.
