NEWTON, Isaac

…..
If I have seen further than others, it is by standing upon the shoulders of giants.
…..
I can calculate the motion of heavenly bodies, but not the madness of people.
…..
To every action there is always opposed an equal reaction.

…..
Truth is ever to be found in simplicity, and not in the multiplicity and confusion of things.
…..
This most beautiful system of the sun, planets and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being.

…..
Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed upon it.

…..
To myself I am only a child playing on the beach, while vast oceans of truth lie undiscovered before me.

Principia

And thus Nature will be very conformable to her self and very simple, performing all the great Motions of the heavenly Bodies by the Attraction of Gravity which intercedes those Bodies, and almost all the small ones of their Particles by some other attractive and repelling Powers which intercede the Particles. The Vis inertiae is a passive Principle by which Bodies persist in their Motion or Rest, receive Motion in proportion to the Force impressing it, and resist as much as they are resisted. By this Principle alone there never could have been any Motion in the World. Some other Principle was necessary for putting Bodies into Motion; and now they are in Motion, some other Principle is necessary for conserving the Motion.
