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
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
I have presented principles of philosophy that are not, however, philosophical but strictly mathematical-that is, those on which the study of philosophy can be based. These principles are the laws and conditions of motions and of forces, which especially relate to philosophy.

Isaac Newton
It is the glory of geometry that from so few principles, fetched from without, it is able to produce so many things.

Isaac Newton
The Synthesis consists in assuming the Causes discovered and established as Principles, and by them explaining the Phaenomena proceeding from them, and proving the Explanations.

Isaac Newton
The quantity of matter is the measure of the same, arising from its density and bulk conjointly.

Isaac Newton
The main Business of Natural Philosophy is to argue from Phaenomena 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
Qu. 31. Have not the small Particles of Bodies certain Powers, Virtues or Forces, by which they act at a distance, not only upon the Rays of Light for reflecting, refracting and reflecting them, but also upon one another for producing a great part of the Phænomena of Nature?

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
Nor could the moon without some such force be retained in its orbit. If this force was too small, it would not sufficiently turn the moon out of a rectilinear course; if it were too great, it would turn it too much, and draw down the moon from its orbit towards the earth.

Isaac Newton
To understand the motions of the planets under the influence of gravity without knowing the cause of gravity is as good a progress in philosophy as to understand the frame of a clock and the dependence of the wheels upon one another without knowing the cause of the gravity of the weight.

Isaac Newton
To derive two or three general Principles of Motion from Phaenomena, and afterwards to tell us how the Properties and Actions of all corporeal Things follow from those manifest Principles, would be a very great step in Philosophy.

Isaac Newton
It may be so, there is no arguing against facts and experiments.

Isaac Newton
Truth is the offspring of silence and unbroken meditation.

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

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
If instead of sending the Observations of seamen to able Mathematicians at Land, the Land would send able Mathematicians to Sea, it would signify much more to the improvement of Navigation and safety of Men's lives and estates on the aliment.

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