Injustice is censured because the censures are afraid of suffering, and not from any fear which they have of doing injustice.
PlatoTo be curious about that which is not one's concern while still in ignorance of oneself is ridiculous.
PlatoMisanthropy ariseth from a man trusting another without having sufficient knowledge of his character, and, thinking him to be truthful, sincere, and honourable, finds a little afterwards that he is wicked, faithless, and then he meets with another of the same character. When a man experiences this often, and more particularly from those whom he considered his most dear and best friends, at last, having frequently made a slip, he hates the whole world, and thinks that there is nothing sound at all in any of them.
Plato
