Isaac Newton

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

"'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."

"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."

"Fidelity and allegiance sworn to the King is only such a fidelity and obedience as is due to him by the law of the land; for were that faith and allegiance more than what the law requires, we would swear ourselves slaves and the King absolute; whereas, by the law, we are free men, notwithstanding those oaths."

"Genius is patience."

"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."

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

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

"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."

"It is reasonable that forces directed toward bodies depend on the nature and the quantity of matter of such bodies, as happens in the case of magnetic bodies."

"My powers are ordinary. Only my application brings me success."

"Religion and philosophy are to be preserved distinct. We are not to introduce divine revelations into philosophy, nor philosophical opinions into religion."

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

"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."

"The motions of the comets are exceedingly regular, and they observe the same laws as the motions of the planets, but they differ from the motions of vortices in every particular and are often contrary to them."

"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."

"To me there has never been a higher source of earthly honor or distinction than that connected with advances in science."

"We are certainly not to relinquish the evidence of experiments for the sake of dreams and vain fictions of our own devising; nor are we to recede from the analogy of Nature, which is wont to be simple and always consonant to itself."
