Isaac Newton
Isaac Newton
Sir Isaac Newton PRSwas an English physicist and mathematicianwho is widely recognised as one of the most influential scientists of all time and a key figure in the scientific revolution. His book Philosophiæ Naturalis Principia Mathematica, first published in 1687, laid the foundations for classical mechanics. Newton made seminal contributions to optics, and he shares credit with Gottfried Wilhelm Leibniz for the development of calculus...

drawn earth force gravity moon motion towards
The moon gravitates towards the earth and by the force of gravity is continually drawn off from a rectilinear motion and retained in its orbit.
cannot parts possibly
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.
bodies divided lesser matter minds particles remain separated
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.
dominion fancy god imagine relative respect word
'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.
god man manner perceives
As a blind man has no idea of colors, so have we no idea of the manner by which the all-wise God perceives and understands all things.
author enlighten heat qualified sufficient system warm
Why there is one body in our System qualified to give light and heat to all the rest, I know no reason but because the Author of the System thought it convenient; and why there is but one body of this kind, I know no reason, but because one was sufficient to warm and enlighten all the rest.
divine introduce nor opinions preserved religion
Religion and philosophy are to be preserved distinct. We are not to introduce divine revelations into philosophy, nor philosophical opinions into religion.
bodies electric forces motion moved particles parts persist planets relation smaller system systems
Just as the system of the sun, planets and comets is put in motion by the forces of gravity, and its parts persist in their motions, so the smaller systems of bodies also seem to be set in motion by other forces and their particles to be variously moved in relation to each other and, especially, by the electric force.
cannot difficult proving render urge
If the experiments which I urge be defective, it cannot be difficult to show the defects; but if valid, then by proving the theory, they must render all objections invalid.
anyone appear certain hypotheses mere offers science since supply truth
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.
furnish hypotheses properties unless
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.
cannot god subsist virtually
God is the same God, always and everywhere. He is omnipresent not virtually only, but also substantially, for virtue cannot subsist without substance.
absolute determine dimension immovable nature position regard relative remains senses similar taken
Absolute space, in its own nature, without regard to anything external, remains always similar and immovable. Relative space is some movable dimension or measure of the absolute spaces, which our senses determine by its position to bodies, and which is vulgarly taken for immovable space.
ascribe compelled divine frame motion planets power system
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.
