Famous Quotations:
Finally we shall place the Sun himself at the center of the universe.
All this is suggested by the systematic procession of events and the
harmony of the whole universe, if only we face facts, as they say, "with
both eyes open." Copernicus, De Revolutionibus Orbium Coelestium
(1543)
If I have seen further [than you and Descartes] it is by standing upon
the shoulders of Giants.
Newton, Letter to Robert Hooke, 1675/6
I do not know how I may appear to the world; but to myself I seem to
have been only like a boy 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.
Newton, Memoirs of Newton, 1855, vol. II, chapter 27.
It is not enough to have a good mind. The main thing is to use it well.
Cogito ergo sum (I think therefore I am.) The first precept was
never to accept a thing as true until I knew it as such without a single
doubt.
Rene Descartes, Discourse on Method
I have taken all knowledge to be my province.
Francis Bacon, Letter to Lord Burleigh, 1592
Knowledge is power.
Bacon, Sacred Meditations
If a man will begin with certainties, he shall end in doubts; but if
he will begin with dounts, he shall end in certainties.
Bacon, The Advancement of Learning
They are ill discoverers that think there is no land, when they can
see nothing but sea.
