Isaac Newton

I know not how others see me, but to myself I seem a small child playing on a beach, delighted at the discovery of a shiny stone or shell, while an entire ocean of Truth lay undiscovered before my eyes.

I seem to have been only like a child playing on the seashore, 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.
