Plato

Philosophy is the highest music.

In practice people who study philosophy too long become very odd birds, not to say thoroughly vicious; while even those who are the best of them are reduced by...[philosophy] to complete uselessness as members of society.

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

if someone got to see the Beautiful itself, absolute, pure, unmixed, not polluted by human flesh or colors or any other great nonsense of mortality, but if he could see the divine Beauty itself in its one form? Do you think it would be a poor life for a human being to look there and to behold it by that which he ought, and to be with it? Or haven't you remembered that in that life alone, when he looks at Beauty in the only way what Beauty can be seen - only then will it become possible for him to give birth no to images of virtue (because he's in touch with no images) but to true virtue (because he is in touch with the true Beauty). The love of the gods belongs to anyone who has given birth to true virtue and nourished it, and if any human being could become immortal, it would be he.

In politics we presume that everyone who knows how to get votes knows how to administer a city or a state. When we are ill... we do not ask for the handsomest physician, or the most eloquent one.

One of the penalties of refusing to participate in politics is that you end up being governed by your inferiors.

Do not train a child to learn by force or harshness; but direct them to it by what amuses their minds, so that you may be better able to discover with accuracy the peculiar bent of the genius of each.

The price good men pay for indifference to public affairs is to be ruled by evil men.

All began to change in the reverse direction and grow more tender. The white hair of the elderly began to grow black; the cheeks of the bearded to grow smooth, and one and all to return to the season of bloom that they had left behind them. Young men__ bodies grew smoother and smaller day by day and night by night till they reverted alike in mind and body to the likes of a newborn infant, and then dwindled right away and were clean lost to sight.

All is flux, nothing stays still

If women are expected to do the same work as men, we must teach them the same things.

...[T]he right way is to give one's attention first to the highest good of the young, just as you expect a good gardener to give his attention first to the young plants, and after that to the others. - Socrates

They deem him their worst enemy who tells them the truth. -Plato, philosopher (427-347 BCE)

The price of apathy towards public affairs is to be ruled by evil men.

The heaviest penalty for declining to rule is to be ruled by someone inferior to yourself.

Every heart sings a song, incomplete, until another heart whispers back. Those who wish to sing always find a song. At the touch of a lover, everyone becomes a poet.

When the tyrant has disposed of foreign enemies by conquest or treaty and there is nothing to fear from them then he is always stirring up some wary or other in order that the people may require a leader.

good people do not need laws to tell them to act responsibly, while bad people will find a way around the laws
