Plato

“The poet is a light and winged and holy thing, and there is no invention in him until he has been inspired and is out of his sneses, and the mind is no longer in him.”

“If particulars are to have meaning, there must be universals.”

“We can easily forgive a child who is afraid of the dark; the real tragedy of life is when men are afraid of the light.”

“The philosopher whose dealings are with divine order himself acquires the characteristics of order and divinity.”

“Courage is knowing what not to fear.”

“Only a philosopher's mind grows wings, since its memory always keeps it as close as possible to those realities by being close to which the gods are divine.”

“The highest reach of injustice is to be deemed just when you are not.”

“When men speak ill of thee, live so as nobody may believe them.”

“Philosophy begins in wonder.”

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

“Haven't you noticed that opinion without knowledge is always a poor thing? At the best it is blind—isn't anyone who holds a true opinion without understanding like a blind man on the right road?”

“[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;—it 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…”

“Cunning... is but the low mimic of wisdom.”

“Wisdom alone is the science of other sciences.”

“No one is a friend to his friend who does not love in return.”

“Calligraphy is a geometry of the soul which manifests itself physically.”

“A dog has the soul of a philosopher.”

“Thinking: the talking of the soul with itself.”

“["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.”

“We are twice armed if we fight with faith.”
