Isaac Newton quotes

Isaac Newton was an English mathematician, physicist, and astronomer, widely regarded as one of the most influential scientists in history. His groundbreaking work laid the foundations for classical mechanics and introduced the laws of motion and universal gravitation. He profoundly shaped the scientific revolution and remains a central figure in the development of modern science. Here are 198 of his quotes:

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

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.

Isaac Newton

To every action there is always opposed an equal reaction.

Isaac Newton

We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances.

Isaac Newton

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

Isaac Newton

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

Isaac Newton

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

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 than to explain all things by conjecture without making sure of any thing.

Isaac Newton

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

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

To every action there is always opposed an equal reaction, or, the mutual actions of two bodies upon each other are always equal, and directed to contrary parts.

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

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

Isaac Newton

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

Isaac Newton

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

Isaac Newton

This most beautiful system The Universe could only proceed from the dominion of an intelligent and powerful Being.

Isaac Newton

What we know is a drop, what we don't know is an ocean.

Isaac Newton

We build too many walls and not enough bridges.

Isaac Newton

Do not several sorts of Rays make Vibrations of several bignesses, which according to their bigness excite Sensations of several Colours, much after the manner that the Vibrations of the Air, according to their several bignesses excite Sensations of several Sounds? And particularly do not the most refrangible Rays excite the shortest Vibrations for making a Sensation of deep violet, the least refrangible the largest form making a Sensation of deep red, and several intermediate sorts of Rays, Vibrations of several intermediate bignesses to make Sensations of several intermediate Colours?

Isaac Newton

In the reign of the Greek Emperor Justinian, and again in the reign of Phocas, the Bishop of Rome obtained some dominion over the Greek Churches, but of no long continuance. His standing dominion was only over the nations of the Western Empire, represented by Daniel's fourth Beast.

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

Daniel was in the greatest credit amongst the Jews, till the reign of the Roman Emperor Hadrian . And to reject his prophecies, is to reject the Christian religion. For this religion is founded upon his prophecy concerning the Messiah .
