Isaac Newton Quotes

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

~ Isaac Newton

Lo que sabemos es una gota de agua, lo que ignoramos es un océano.

~ Isaac Newton

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

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

~ Isaac Newton

This most beautiful system of the sun, planets and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being.

~ Isaac Newton

I can calculate the motion of heavenly bodies but not the madness of people.

~ Isaac Newton

Gravity explains the motions of the planets, but it cannot explain who sets the planets in motion.

~ Isaac Newton

This principle of nature being very remote from the conceptions of Philosophers, I forbore to describe it in that book, least I should be accounted an extravagant freak and so prejudice my Readers against all those things which were the main designe of the book.

~ Isaac Newton

If I have seen further it is by standing on the shoulders of Giants.

~ Isaac Newton

What goes up must come down.

~ Isaac Newton

How came the bodies of animals to be contrived with so much art, and for what ends were their several parts?Was the eye contrived without skill in Opticks, and the ear without knowledge of sounds?...and these things being rightly dispatch’d, does it not appear from phænomena that there is a Being incorporeal, living, intelligent...?

~ Isaac Newton

Blind metaphysical necessity, which is certainly the same always and every where, could produce no variety of things. All that diversity of natural things which we find suited to different times and places could arise from nothing but the ideas and will of a Being, necessarily existing.

~ Isaac Newton

For every action, there is an equal and opposite reaction.

~ Isaac Newton

Truth is the offspring of silence and meditation. I keep the subject constantly before me and wait 'til the first dawnings open slowly, by little and little, into a full and clear light.

~ Isaac Newton

A Vulgar Mechanick can practice what he has been taught or seen done, but if he is in an error he knows not how to find it out and correct it, and if you put him out of his road he is at a stand. Whereas he that is able to reason nimbly and judiciously about figure, force, and motion, is never at rest till he gets over every rub.(from a letter dated 25 May, 1694)

~ Isaac Newton

Plato is my friend, Aristotle is my friend, but my greatest friend is truth.

~ Isaac Newton

He who thinks half-heartedly will not believe in God, but he who really thinks has to believe in God.

~ Isaac Newton

For I see not what there is desirable in publick esteeme, were I able to acquire & maintaine it. It would perhaps increase my acquaintance, the thing which I chiefly study to decline.

~ Isaac Newton

If I have seen farther it is by standing on the shoulders of giants.

~ Isaac Newton

God who gave Animals self motion beyond our understanding is without doubt able to implant other principles of motion in bodies [which] we may understand as little. Some would readily grant this may be a Spiritual one; yet a mechanical one might be showne, did not I think it better to pass it by.

~ Isaac Newton

If I have seen further than others, it is by standing upon the shoulders of giants.

~ Isaac Newton

We are certainly not to relinquish the evidence of experiments for the sake of dreams and vain fictions of our own devising; nor are we to recede from the analogy of Nature, which is wont to be simple and always consonant to itself.

~ Isaac Newton

God in the beginning formed matter in solid, massy, hard, impenetrable, movable particles, of such sizes and figures, and with such other properties, and in such proportion to space, as most conduced to the end for which he formed them.

~ Isaac Newton

The motions of the comets are exceedingly regular, and they observe the same laws as the motions of the planets, but they differ from the motions of vortices in every particular and are often contrary to them.

~ Isaac Newton

It is indeed a matter of great difficulty to discover, and effectually to distinguish, the true motions of particular bodies from the apparent because the parts of that immovable space, in which those motions are performed, do by no means come under the observation of our senses.

~ Isaac Newton

To every action there is always opposed an equal reaction.

~ Isaac Newton

To explain all nature is too difficult a task for any one man or even for any one age. 'Tis much better to do a little with certainty & leave the rest for others that come after you.

~ Isaac Newton

To me there has never been a higher source of earthly honor or distinction than that connected with advances in science.

~ Isaac Newton

If anyone offers conjectures about the truth of things from the mere possibility of hypotheses, I do not see by what stipulation anything certain can be determined in any science, since one or another set of hypotheses may always be devised which will appear to supply new difficulties.

~ Isaac Newton

If I have done the public any service, it is due to my patient thought.

~ Isaac Newton

The smaller the planets are, they are, other things being equal, of so much the greater density; for so the powers of gravity on their several surfaces come nearer to equality. They are likewise, other things being equal, of the greater density, as they are nearer to the sun.

~ Isaac Newton

Religion and philosophy are to be preserved distinct. We are not to introduce divine revelations into philosophy, nor philosophical opinions into religion.

~ Isaac Newton

Gravity may put the planets into motion, but without the divine Power, it could never put them into such a circulating motion as they have about the Sun; and therefore, for this as well as other reasons, I am compelled to ascribe the frame of this System to an intelligent Agent.

~ Isaac Newton

Atheism is so senseless. When I look at the solar system, I see the earth at the right distance from the sun to receive the proper amounts of heat and light. This did not happen by chance.

~ Isaac Newton

In the absence of any other proof, the thumb alone would convince me of God's existence.
