The ancients considered mechanics in a twofold respect: as rational, which proceeds accurately by demonstration, and practical. To practical mechanics all the manual arts belong, from which mechanics took its name. Isaac Newton Read Quote
Resistance is usually ascribed to bodies at rest, and impulse to those in motion, but motion and rest, as commonly conceived, are only relatively distinguished; nor are those bodies always truly at rest, which commonly are taken to be so. Isaac Newton Read Quote
Nothing can be divided into more parts than it can possibly be constituted of. But matter (i.e. finite) cannot be constituted of infinite parts. Isaac Newton Read Quote
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 Read Quote
The hypothesis of matter’s being at first evenly spread through the heavens is, in my opinion, inconsistent with the hypothesis of innate gravity without a supernatural power to reconcile them, and therefore, it infers a deity. Isaac Newton Read Quote
I there represent that I sent notice of my method to Mr. Leibnitz before he sent notice of his method to me, and left him to make it appear that he had found his method before the date of my letter. Isaac Newton Read Quote
That the divided but contiguous particles of bodies may be separated from one another is a matter of observation; and, in the particles that remain undivided, our minds are able to distinguish yet lesser parts, as is mathematically demonstrated. Isaac Newton Read Quote
Hypotheses should be subservient only in explaining the properties of things but not assumed in determining them, unless so far as they may furnish experiments. Isaac Newton Read Quote
God’ is a relative word and has a respect to servants, and ‘Deity’ is the dominion of God, not over his own body, as those imagine who fancy God to be the soul of the world, but over servants. Isaac Newton Read Quote
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.
