"They say that to do injustice is, by nature, good; to suffer injustice, evil, but that the evil is greater than the good. And so when 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."

"He who commits injustice is ever made more wretched than he who suffers it."

"Wonder is the only beginning of philosophy."

"Everything desires not like but unlike: for example, the dry desires the moist, the cold the hot, the bitter the sweet, the sharp the blunt, the void the full, the fill the void, and so of all other things; for the opposite is the food of the opposite, whereas receives nothing from like.,."

"All knowledge, when separated from justice and virtue, is seen to be cunning and not wisdom."

"The rhetorician need not know the truth about things; he has only to discover some way of persuading the ignorant that he has more knowledge than those who know."

"Similarly with regard to truth, won't we say that a soul is maimed if it hates a voluntary falsehood, cannot endure to have one in itself, and is greatly angered when it exists in others, but is nonetheless content to accept an involuntary falsehood, isn't angry when it is caught being ignorant, and bears its lack of learning easily, wallowing in it like a pig?"

"If the truth of all things that are is always in our soul, then the soul must be immortal, so you should take courage and whatever you do not happen to know, that is to remember, at present, you must endeavor to discover and recollect I cannot swear to everything I have said in this argument but one thing I am ready to fight for in word and deed, that we shall be better, braver and more active men if we believe it right to look for what we do not know, than if we think we cannot discover it and have no duty to seek it."

"A man ought not to return evil for evil, as many think, since at no time ought we to do an injury to our neighbor."

"Wonder is the only beginning of philosophy."
