Famous Isaac Newton Quotes

A cylinder of air reaching to the top of the atmosphere is of equal weight with a cylinder of water about 33 feet high. – Isaac Newton

What is there in places empty of matter? and Whence is it that the sun and planets gravitate toward one another without dense matter between them? Whence is it that Nature doth nothing in vain? and Whence arises all that order and beauty which we see in the world? To what end are comets? and Whence is it that planets move all one and the same way in orbs concentrick, while comets move all manner of ways in orbs very excentrick? and What hinders the fixed stars from falling upon one another? – Isaac Newton

Oh Diamond! Diamond! thou little knowest the mischief done! [Apocryphal] – Isaac Newton

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

This Excellent Mathematician having given us, in the Transactions of February last, an account of the cause, which induced him to think upon Reflecting Telescopes, instead of Refracting ones, hath thereupon presented the curious world with an Essay of what may be performed by such Telescopes; by which it is found, that Telescopical Tubes may be considerably shortened without prejudice to their magnifying effect. On his invention of the catadioptrical telescope, as he communicated to the Royal Society. – Isaac Newton

His epitaph: Who, by vigor of mind almost divine, the motions and figures of the planets, the paths of comets, and the tides of the seas first demonstrated. – Isaac Newton

The wonderful arrangement and harmony of the cosmos would only originate in the plan of an almighty omniscient being. This is and remains my greatest comprehension. – Isaac Newton

Pontus, instituted among all people, as an addition or corollary of devotion towards God, that festival days and assemblies should be celebrated to them who had contended for the faith (that is, to lie martyrs). – Isaac Newton

‘Tis the temper of the hot and superstitious part of mankind in matters of religion ever to be fond of mysteries, and for that reason to like best what they understand least. – Isaac Newton

Errors are not in the art but in the artificers. – Isaac Newton

A good watch may serve to keep a recconing at Sea for some days and to know the time of a Celestial Observ[at]ion: and for this end a good Jewel watch may suffice till a better sort of Watch can be found out. But when the Longitude at sea is once lost, it cannot be found again by any watch. – Isaac Newton

All knowledge and understanding of the Universe was no more than playing with stones and shells on the seashore of the vast imponderable ocean of truth. – Isaac Newton

A man may imagine things that are false, but he can only understand things that are true, for if the things be false, the apprehension of them is not understanding. – Isaac Newton

Live your life as an Exclamation rather than an Explanation – Isaac Newton

He rules all things, not as the world soul but as the lord of all. And because of his dominion he is called Lord God Pantokrator. For god is a relative word and has reference to servants, and godhood is the lordship of God, not over his own body as is supposed by those for whom God is the world soul’, but over servants. – Isaac Newton

Our design, not respecting arts, but philosophy, and our subject, not manual, but natural powers, we consider chiefly those things which relate to gravity, levity, elastic force, the resistance of fluids, and the like forces, whether attractive or impulsive; and therefore we offer this work as mathematical principles of philosophy; for all the difficulty of philosophy seems to consist in this from the phenomena of motions to investigate the forces of nature, and then from these forces to demonstrate the other phenomena. – 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 design of the book. – Isaac Newton

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

Is not Fire a Body heated so hot as to emit Light copiously? For what else is a red hot Iron than Fire? And what else is a burning Coal than red hot Wood? – Isaac Newton

The alternation of motion is ever proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed. – Isaac Newton

In experimental philosophy, propositions gathered from phenomena by induction should be considered either exactly or very nearly true notwithstanding any contrary hypotheses, until yet other phenomena make such propositions either more exact or liable to exceptions. – Isaac Newton

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

My principal method for defeating error and heresy is by establishing the truth. One purposes to fill a bushel with tares, but if I can fill it first with wheat, I may defy his attempts. – Isaac Newton

Did blind chance know that there was light and what was its refraction, and fit the eyes of all creatures after the most curious manner to make use of it? These and other suchlike considerations, always have, and always will prevail with mankind, to believe that there is a Being who made all things, who has all things in his power, and who is therefore to be feared. – Isaac Newton

The best and safest way of philosophizing seems to be, first to enquire diligently into the properties of things, and to establish those properties by experiences [experiments] and then to proceed slowly to hypotheses for the explanation of them. For hypotheses should be employed only in explaining the properties of things, but not assumed in determining them; unless so far as they may furnish experiments. – Isaac Newton

For the Rays, to speak properly, have no Color. In them there is nothing else than a certain power and disposition to stir up a sensation of this Color or that. – Isaac Newton

Nature is very consonant and conformable with herself. – Isaac Newton

It is the weight, not numbers of experiments that is to be regarded. – Isaac Newton

Every particle of matter is attracted by or gravitates to every other particle of matter with a force inversely proportional to the squares of their distances. – Isaac Newton

Nature does nothing in vain when less will serve; for Nature is pleased with simplicity and affects not the pomp of superfluous causes. – Isaac Newton

I do not define time, space, place, and motion, as being well known to all. Only I must observe that the common people conceive those quantities under no other notions but from the relation they bear to sensible objects. And thence arise certain prejudices, for the removing of which it will be convenient to distinguish them into absolute and relative, true and apparent, mathematical and common. – Isaac Newton

If you are affronted it is better to pass it by in silence, or with a jest, though with some dishonor, than to endeavor revenge. If you can keep reason above passion, that and watchfulness will be your best defenders. – Isaac Newton

I have not been able to discover the cause of those properties of gravity from phenomena, and I frame no hypotheses; for whatever is not deduced from the phenomena is to be called a hypothesis, and hypotheses, whether metaphysical or physical, whether of occult qualities or mechanical, have no place in experimental philosophy. – Isaac Newton

If I have ever made any valuable discoveries, it has been due more to patient attention, than to any other talent – Isaac Newton

I see I have made myself a slave to Philosophy, but if I get free of Mr. Linus’s business I will resolutely bid adew to it eternally, excepting for what I do for my private satisfaction or leave to come out after me. For I see a man must either resolve to put out nothing new or to become a slave to defend it. – Isaac Newton

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

From the same principles, I now demonstrate the frame of the System of the World. – Isaac Newton

Thus far I have explained the phenomena of the heavens and of our sea by the force of gravity, but I have not yet assigned a cause to gravity. Indeed, this force arises from some cause that penetrates as far as the centers of the sun and planets without any diminution of its power to act, and that acts not in proportion to the quantity of the surfaces of the particles on which it acts (as mechanical causes are wont to do) but in proportion to the quantity of solid matter, and whose action is extended everywhere to immense distances, always decreasing as the squares of the distances. – Isaac Newton

To arrive at the simplest truth requires years of contemplation. – Isaac Newton

To explain all nature is too difficult a task for any one man or even for any one age. – Isaac Newton

The instinct of brutes and insects can be the effect of nothing else than the wisdom and skill of a powerful ever-living agent. – Isaac Newton

If the ancient churches, in debating and deciding the greatest mysteries of religion, knew nothing of these two texts, I understand not why we should be so fond of them now the debate is over. – Isaac Newton

Plato is my friend, Aristotle is my friend, but my greatest friend is truth. – Isaac Newton

Philosophy is such an impertinently litigious lady that a man had as good be engaged in lawsuits as have to do with her. – Isaac Newton

The seed of a tree has the nature of a branch or twig or bud. It is a part of the tree, but if separated and set in the earth to be better nourished, the embryo or young tree contained in it takes root and grows into a new tree. – Isaac Newton

Tact is the art of making a point without making an enemy. – Isaac Newton

We are not to consider the world as the body of God: he is an uniform being, void of organs, members, or parts; and they are his creatures, subordinate to him, and subservient to his will. – Isaac Newton

And from true lordship it follows that the true God is living, intelligent, and powerful; from the other perfections, that he is supreme, or supremely perfect. He is eternal and infinite, omnipotent and omniscient; that is, he endures from eternity to eternity; and he is present from infinity to infinity; he rules all things, and he knows all things that happen or can happen. – Isaac Newton

No old Men (excepting Dr. Wallis) love Mathematics. – Isaac Newton

I am ashamed to tell you to how many figures I carried these calculations [of Pi], having no other business at the time – Isaac Newton

I know not how I seem to others, but to myself I am but a small child wandering upon the vast shores of knowledge, every now and then finding a small bright pebble to content myself with while the vast ocean of undiscovered truth lay before me. – Isaac Newton

All my discoveries have been made in answer to prayer. – Isaac Newton

From what has been said it is also evident, that the Whiteness of the Sun’s Light is compounded all the Colours wherewith the several sorts of Rays whereof that Light consists, when by their several Refrangibilities they are separated from one another, do tinge Paper or any other white Body whereon they fall. For those Colours … are unchangeable, and whenever all those Rays with those their Colours are mix’d again, they reproduce the same white Light as before. – 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

Our present work sets forth mathematical principles of philosophy. For the basic problem of philosophy seems to be to discover the forces of nature from the phenomena of motions and then to demonstrate the other phenomena from these forces. It is to these ends that the general propositions in books 1 and 2 are directed, while in book 3 our explanation of the system of the world illustrates these propositions. – Isaac Newton

What we know is a drop, what we don’t know is an ocean. – Isaac Newton

As I am writing, another illustration of ye generation of hills proposed above comes into my mind. Milk is as uniform a liquor as ye chaos was. If beer be poured into it & ye mixture let stand till it be dry, the surface of ye curdled substance will appear as rugged & mountanous as the Earth in any place. – Isaac Newton

I can calculate the motion of heavenly bodies, but not the madness of people. – Isaac Newton

You sometimes speak of gravity as essential and inherent to matter. Pray do not ascribe that notion to me, for the cause of gravity is what I do not pretend to know, and therefore would take more time to consider of it. – Isaac Newton

Now the smallest Particles of Matter may cohere by the strongest Attractions, and compose bigger Particles of weaker Virture…. There are therefore Agents in Nature able to make the Particles of Bodies stick together by very strong Attraction. And it is the Business of experimental Philosophy to find them out. – Isaac Newton

We account the Scriptures of God to be the most sublime philosophy. – Isaac Newton

If I had stayed for other people to make my tools and things for me, I had never made anything. – Isaac Newton

What Descartes did was a good step. You have added much several ways, and especially in taking the colors of thin plates into philosophical consideration. If I have seen a little further it is by standing on the shoulders of Giants. – Isaac Newton

What goes up must come down. – Isaac Newton

My Design in this Book is not to explain the Properties of Light by Hypotheses, but to propose and prove them by Reason and Experiments: In order to which, I shall premise the following Definitions and Axioms. – Isaac Newton

Therefore, to the same natural effects we must, as far as possible, assign the same causes. – Isaac Newton

God is able to create particles of matter of several sizes and figures and perhaps of different densities and forces, and thereby to vary the laws of nature, and make worlds of several sorts in several parts of the Universe. – Isaac Newton

As in Mathematics, so in Natural Philosophy, the Investigation of difficult Things by the Method of Analysis, ought ever to precede the Method of Composition. This Analysis consists in making Experiments and Observations, and in drawing general Conclusions from them by Induction, and admitting of no Objections against the Conclusions, but such as are taken from Experiments, or other certain Truths. For Hypotheses are not to be regarded in experimental Philosophy. – Isaac Newton

Where both are friends, it is right to prefer truth. – Isaac Newton

Doth not this Ethereal Medium in passing out of Water, Glass, Crystal, and other compact and dense Bodies into empty Spaces, grow denser and denser by degrees, and by that means refract the Rays of Light not in a point, but by bending them gradually in curve Lines? And doth not the gradual condensation of this Medium extends to some distance from the Bodies, and thereby cause the Inflexions of the Rays of Light, which pass by the edges of dense Bodies, at some distance from the Bodies? – Isaac Newton

Let me think… I wonder if an anvil will drop like an apple? – Isaac Newton

The great ocean of truth lay all undiscovered before me. – Isaac Newton

Every action has an equal and opposite reaction – Isaac Newton

No great discovery was ever made without a bold guess. – Isaac Newton

No sciences are better attested than the religion of the Bible. – Isaac Newton

This thing is but a puny imitation of a much grander system whose laws you know, and I am not able to convince you that this mere toy is without a designer or maker; yet you profess to believe that the great original from which the design is taken has come into being without either designer or maker! Now tell me by what sort of reasoning do you reach such an incongruous conclusion? – Isaac Newton

A Heavenly Master governs all the world as Sovereign of the universe. We are astonished at Him by reason of His perfection, we honor Him and fall down before Him because of His unlimited power. From blind physical necessity, which is always and everywhere the same, no variety adhering to time and place could evolve, and all variety of created objects which represent order and life in the universe could happen only by the willful reasoning of its original Creator, Whom I call the Lord God. – Isaac Newton

Are not gross bodies and light convertible into one another; and may not bodies receive much of their activity from the particles of light which enter into their composition? The changing of bodies into light, and light into bodies, is very conformable to the course of Nature, which seems delighted with transmutations. – Isaac Newton

Whence arises all that order and beauty we see in the world? – Isaac Newton

The main Business of Natural Philosophy is to argue from Phænomena without feigning Hypotheses, and to deduce Causes from Effects till we come to the very first Cause, which certainly is not mechanical; and not only to unfold the Mechanism of the World, but chiefly to resolve these, and to such like Questions. – 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

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

Do not great Bodies conserve their heat the longest, their parts heating one another, and may not great dense and fix’d Bodies, when heated beyond a certain degree, emit Light so copiously, as by the Emission and Re-action of its Light, and the Reflexions and Refractions of its Rays within its Pores to grow still hotter, till it comes to a certain period of heat, such as is that of the Sun? – Isaac Newton

To any action there is always an opposite and equal reaction; in other words, the actions of two bodies upon each other are always equal and always opposite in direction. – 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

To every action there is always opposed an equal reaction. – Isaac Newton

The way to chastity is not to struggle directly with incontinent thoughts but to avert the thoughts by some imployment, or by reading, or meditating on other things. – Isaac Newton

Pictures, propagated by motion along the fibers of the optic nerves in the brain, are the cause of vision. – Isaac Newton

He who thinks half-heartedly will not believe in God; but he who really thinks has to believe in God. – Isaac Newton

If two angels were sent down from heaven -one to conduct an empire and the other to sweep the streets -they would feel no inclination to change employment because an angel would know that no matter what we are doing, it’s an opportunity to bring joy, deepen our understanding and expand our life. – Isaac Newton

As a blind man has no idea of colors, so we have no idea of the manner by which the all-wise God perceives and understands all 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

Every body persists in a state of rest or of uniform motion in a straight line, unless it is compelled to change that state by forces having impact upon it. – Isaac Newton

When two forces unite, their efficiency double. – Isaac Newton

My powers are ordinary. Only my application brings me success. – Isaac Newton
