I am not an Athenian or a Greek, but a citizen of the world.
Let him who would move the world first move himself.
To move the world we must move ourselves.
True wisdom comes to each of us when we realize how little we understand about life, ourselves, and the world around us.
The great honor in the world is to be what we pretend to be.
I certainly have many enemies, and this is what will be my destruction if I am destroyed; of that I am certain; not Meletus, nor yet Anytus, but the envy and detraction of the world, which has been the death of many good men, and will probably be the death of many more; there is no danger of my being the last of them.
The great enemy of is the world, not exactly in the theological sense, yet in one not wholly different – the world as the hater of truth and lover of appearance, occupied in the pursuit of gain and pleasure rather than of knowledge, banded together against the few good and wise men, and devoid of true education.
You will never do anything in this world without courage. It is the greatest quality of the mind next to honor.
I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.
The world is a dangerous place, not because of those who do evil, but because of those who look on and do nothing.
