Errors are not in the art but in the artificers. - Isaac Newton

"Les hommes construisent trop de murs et pas assez de ponts."

"Truth is ever to be found in the simplicity, and not in the multiplicity and confusion of things."

"Tact is the art of making a point without making an enemy."

"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."

"My powers are ordinary. Only my application brings me success."
