Plato

And the true order of going, or being led by another, to the things of love, is to begin from the beauties of earth and mount upwards for the sake of that other beauty, using these steps only, and from one going on to two, and from two to all fair forms to fair practices, and from fair practices to fair notions, until from fair notions he arrives at the notion of absolute beauty, and at last knows what the essence of beauty is.

But the chief penalty is to be governed by someone worse if a man will not himself hold office and rule.

And we must beg Homer and the other poets not to be angry if we strike out these and similar passages, not because they are unpoetical, or unattractive to the popular ear, but because the greater the poetical charm in them, the less are they meant for the ears of boys and men who are meant to be free, and who should fear slavery more than death.

With regard to this question modern physics takes a definite stand against the materialism of Democritus and for Plato and the Pythagoreans. The elementary particles are certainly not eternal and indestructible units of matter, they can actually be transformed into each other. ... The elementary particles in Plato's Timaeus are finally not substance but mathematical forms.

Watch a man at play for an hour and you can learn more about him than in talking to him for a year.

The judge should not be young; he should have learned to know evil, not from his own soul, but from late and long observation of the nature of evil in others: knowledge should be his guide, not personal experience.

False words are not only evil in themselves, but they infect the soul with evil.

What is Plato, but Moses speaking in Attic Greek?

Mankind censure injustice fearing that they may be the victims of it, and not because they shrink from committing it.

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

We are ready to acknowledge that Homer is the greatest of poets and first of tragedy writers; but we must remain firm in our conviction that hymns to the gods and praises of famous men are the only poetry which ought to be admitted into our State. For if you go beyond this and allow the honeyed muse to enter, either in epic or lyric verse, not law and the reason of mankind, which by common consent have ever been deemed best, but pleasure and pain will be the rulers in our State....
And now since we have reverted to the subject of poetry, let this our defence serve to show the reasonableness of our former judgment in sending away out of our State an art having the tendencies which we have described; for reason constrained us. But that she may impute to us any harshness or want of politeness, let us tell her that there is an ancient quarrel between philosophy and poetry; of which there are many proofs, such as the saying of 'the yelping hound howling at her lord,' or of one 'mighty in the vain talk of fools,' and 'the mob of sages circumventing Zeus,' and the 'subtle thinkers who are beggars after all'; and there are innumerable other signs of ancient enmity between them.
Notwithstanding this, let us assure our sweet friend and the sister arts of imitation that if she will only prove her title to exist in a well-ordered State we shall be delighted to receive her — we are very conscious of her charms; but we may not on that account betray the truth.

Plato held that those souls which in a previous state of existence (antedating Athens) had obtained the clearest glimpses of eternal truth entered into the bodies of persons who became philosophers. Plato himself was a philosopher. The souls that had least contemplated divine truth animated the bodies of usurpers and despots. Dionysius I, who had threatened to decapitate the broad- browed philosopher, was a usurper and a despot. Plato, doubtless, was not the first to construct a system of philosophy that could be quoted against his enemies; certainly he was not the last.

Bodily exercise, when compulsory, does no harm to the body; but knowledge which is acquired under compulsion obtains no hold on the mind.

The gods are not magicians who transform themselves; neither do they deceive mankind in any way.

After much effort, as names, definitions, sights, and other data of sense, are brought into contact and friction one with another, in the course of scrutiny and kindly testing by men who proceed by question and answer without ill will, with a sudden flash there shines forth understanding about every problem, and an intelligence whose efforts reach the furthest limits of human powers.

But tell me, this physician of whom you were just speaking, is he a moneymaker, an earner of fees, or a healer of the sick?

Now in this island of Atlantis there was a great and wonderful empire which had rule over the whole island and several others, and over parts of the continent and, furthermore, the men of Atlantis had subjected the parts of Libya within the columns of Heracles as far as Egypt, and of Europe as far as Tyrrhenia.This vast power, gathered into one, endeavored to subdue at a blow our country and yours and the whole of the region within the straits, and then, Solon, your country shone forth, in the excellence of her virtue and strength, among all mankind.

In Plato and to a lesser extent in Aristotle we read that practical concerns are low and vulgar. It follows that business, as an inherently practical enterprise, is hardly worthy of esteem. Given the place of Plato and Aristotle on the intellectual landscape, we have a partial explanation of the disdain that members of the cultural elite have always exhibited toward business.

Plato's discovery went as follows.

You learn more about a person in an hour of play than in a year of conversation.
