Plato is my friend, Aristotle is my friend, but my greatest friend is truth.

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.

If I have seen further it is by standing on the shoulders of Giants.

-- Charles Darwin

It's easier to ask forgiveness than it is to get permission.
