“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.”
― Isaac Newton

“We consider it a good principle to explain the phenomena by the simplest hypothesis possible.”

“From all this we concluded that the first two divisions of theoretical philosophy should
rather be called guesswork than knowledge, theology because of its completely invisible
and ungraspable nature, physics because of the unstable and unclear nature of the matter;
hence there is no hope that philosophers will ever be agreed about them; and that only
mathematics can provide sure and unshakable knowledge to its devotees, provided one
approaches it rigorously. For its kind of proof proceeds by indisputable methods, namely
arithmetic and geometry (tr. Toomer, p. 6).”

“Trials are medicines which our gracious and wise Physician prescribes because we need them; and he proportions the frequency and weight of them to what the case requires. Let us trust his skill and thank him for his prescription.”
