“Geometry does not teach us to draw these lines, but requires them to be drawn; for it requires that the learner should first be taught to describe these accurately, before he enters upon geometry; then it shows how by these operations problems may be solved.”

Preface (8 May 1686)
Philosophiae Naturalis Principia Mathematica (1687)
Context: 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. But as artificers do not work with perfect accuracy, it comes to pass that mechanics is so distinguished from geometry, that what is perfectly accurate is called geometrical; what is less so is called mechanical. But the errors are not in the art, but in the artificers. He that works with less accuracy is an imperfect mechanic: and if any could work with perfect accuracy, he would be the most perfect mechanic of all; for the description of right lines and circles, upon which geometry is founded, belongs to mechanics. Geometry does not teach us to draw these lines, but requires them to be drawn; for it requires that the learner should first be taught to describe these accurately, before he enters upon geometry; then it shows how by these operations problems may be solved.

“This Being governs all things, not as the soul of the world, but as Lord over all: And on account of his dominion he is wont to be called Lord God παντοκρáτωρ or Universal Ruler.”

Philosophiae Naturalis Principia Mathematica (1687), Scholium Generale (1713; 1726)
Context: This Being governs all things, not as the soul of the world, but as Lord over all: And on account of his dominion he is wont to be called Lord God παντοκρáτωρ or Universal Ruler. For 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. The supreme God is a Being eternal, infinite, absolutely perfect; but a being, however perfect, without dominion, cannot be said to be Lord God; for we say, my God, your God, the God of Israel, the God of Gods, and Lord of Lords; but we do not say, my Eternal, your Eternal, the Eternal of Israel, the Eternal of Gods; we do not say, my Infinite, or my Perfect: These are titles which have no respect to servants. The word God usually signifies Lord; but every lord is not a God. It is the dominion of a spiritual being which constitutes a God; a true, supreme or imaginary dominion makes a true, supreme or imaginary God. And from his true dominion it follows, that the true God is a Living, Intelligent and Powerful Being; and from his other perfections, that he is Supreme or most Perfect. He is Eternal and Infinite, Omnipotent and Omniscient; that is, his duration reaches from Eternity to Eternity; his presence from Infinity to Infinity; he governs all things, and knows all things that are or can be done. He is not Eternity or Infinity, but Eternal and Infinite; he is not Duration or Space, but he endures and is present. He endures for ever, and is every where present; and by existing always and every where, he constitutes Duration and Space. Since every particle of Space is always, and every indivisible moment of Duration is every where, certainly the Maker and Lord of all things cannot be never and no where. Every soul that has perception is, though in different times and in different organs of sense and motion, still the same indivisible person. There are given successive parts in duration, co-existant parts in space, but neither the one nor the other in the person of a man, or his thinking principle; and much less can they be found in the thinking substance of God. Every man, so far as he is a thing that has perception, is one and the same man during his whole life, in all and each of his organs of sense. God is the same God, always and every where. He is omnipresent, not virtually only, but also substantially; for virtue cannot subsist without substance. In him are all things contained and moved; yet neither affects the other: God suffers nothing from the motion of bodies; bodies find no resistance from the omnipresence of God. 'Tis allowed by all that the supreme God exists necessarily; and by the same necessity he exists always and every where. Whence also he is all similar, all eye, all ear, all brain, all arm, all power to perceive, to understand, and to act; but in a manner not at all human, in a manner not at all corporeal, in a manner utterly unknown to us. As a blind man has no idea of colours, so have we no idea of the manner by which the all-wise God perceives and understands all things. He is utterly void of all body and bodily figure, and can therefore neither be seen, nor heard, nor touched; nor ought to be worshipped under the representation of any corporeal thing. We have ideas of his attributes, but what the real substance of any thing is, we know not. In bodies we see only their figures and colours, we hear only the sounds, we touch only their outward surfaces, we smell only the smells, and taste the favours; but their inward substances are not to be known, either by our senses, or by any reflex act of our minds; much less then have we any idea of the substance of God. We know him only by his most wise and excellent contrivances of things, and final causes; we admire him for his perfections; but we reverence and adore him on account of his dominion. For we adore him as his servants; and a God without dominion, providence, and final causes, is nothing else but Fate and Nature. Blind metaphysical necessity, which is certainly the same always and every where, could produce no variety of things. All that diversity of natural things which we find, suited to different times and places, could arise from nothing but the ideas and will of a Being necessarily existing. But by way of allegory, God is said to see, to speak, to laugh, to love, to hate, to desire, to give, to receive, to rejoice, to be angry, to fight, to frame, to work, to build. For all our notions of God are taken from the ways of mankind, by a certain similitude which, though not perfect, has some likeness however. And thus much concerning God; to discourse of whom from the appearances of things, does certainly belong to Natural Philosophy.

“Their writings contain covenant between God and his people, with instructions for keeping this covenant; instances of God’s judgments upon them that break it: and predictions of things to come.”

Vol. I, Ch. 1: Introduction concerning the Compilers of the books of the Old Testament
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: The authority of Emperors, Kings, and Princes, is human. The authority of Councils, Synods, Bishops, and Presbyters, is human. The authority of the Prophets is divine, and comprehends the sum of religion, reckoning Moses and the Apostles among the Prophets; and if an Angel from Heaven preach any other gospel, than what they have delivered, let him be accursed. Their writings contain covenant between God and his people, with instructions for keeping this covenant; instances of God’s judgments upon them that break it: and predictions of things to come. While the people of God keep the covenant they continue to be his people: when they break it they cease to be his people or church, and become the Synagogue of Satan, who say they are Jews and are not. And no power on earth is authorized to alter this covenant.
The predictions of things to come relate to the state of the Church in all ages: and amongst the old Prophets, Daniel is most distinct in order of time, and easiest to be understood: and therefore in those things which relate to the last times, he must be made the key to the rest.

“He gave this and the Prophecies of the Old Testament, not to gratify mens curiosities by enabling them to foreknow things, but that after they were fulfilled they might be interpreted by the event, and his own Providence, not the Interpreters, be then manifested thereby to the world.”

Vol. II, Ch. 1 : Introduction, concerning the time when the Apocalypse was written
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: The folly of Interpreters has been, to foretell times and things by this Prophecy, as if God designed to make them Prophets. By this rashness they have not only exposed themselves, but brought the Prophecy also into contempt.
The design of God was much otherwise. He gave this and the Prophecies of the Old Testament, not to gratify mens curiosities by enabling them to foreknow things, but that after they were fulfilled they might be interpreted by the event, and his own Providence, not the Interpreters, be then manifested thereby to the world. For the event of things predicted many ages before, will then be a convincing argument that the world is governed by providence. For, as the few and obscure Prophecies concerning Christ’s first coming were for setting up the Christian religion, which all nations have since corrupted; so the many and clear Prophecies concerning the things to be done at Christ’s second coming, are not only for predicting but also for effecting a recovery and re-establishment of the long-lost truth, and setting up a kingdom wherein dwells righteousness. The event will prove the Apocalypse; and this Prophecy, thus proved and understood, will open the old Prophets, and all together will make known the true religion, and establish it. For he that will understand the old Prophets, must begin with this; but the time is not yet come for understanding them perfectly, because the main revolution predicted in them is not yet come to pass. In the days of the voice of the seventh Angel, when he shall begin to sound, the mystery of God shall be finished, as he hath declared to his servants the Prophets: and then the kingdoms of this world shall become the kingdom of our Lord and his Christ, and he shall reign for ever, Apoc. x. 7. xi. 15. There is already so much of the Prophecy fulfilled, that as many as will take pains in this study, may see sufficient instances of God’s providence: but then the signal revolutions predicted by all the holy Prophets, will at once both turn men’s eyes upon considering the predictions, and plainly interpret them. Till then we must content ourselves with interpreting what hath been already fulfilled.
Amongst the Interpreters of the last age there to scarce one of note who hath not made some discovery worth knowing; and thence I seem to gather that God is about opening these mysteries. The success of others put me upon considering it; and if I have done any thing which may be useful to following writers, I have my design.

“What is there in places empty of matter? and Whence is it that the sun and planets gravitate toward one another without dense matter between them? Whence is it that Nature doth nothing in vain?”

Query 28 : Are not all Hypotheses erroneous in which Light is supposed to consist of Pression or Motion propagated through a fluid medium?
Opticks (1704)
Context: What is there in places empty of matter? and Whence is it that the sun and planets gravitate toward one another without dense matter between them? Whence is it that Nature doth nothing in vain? and Whence arises all that order and beauty which we see in the world? To what end are comets? and Whence is it that planets move all one and the same way in orbs concentrick, while comets move all manner of ways in orbs very excentrick? and What hinders the fixed stars from falling upon one another?

“Fidelity & 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”

Letter to Dr. Covel Feb. 21, (1688-9) Thirteen Letters from Sir Isaac Newton to J. Covel, D.D. (1848)
Context: 1. Fidelity & 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. 2. When, therefore, the obligation by the law to fidelity and allegiance ceases, that by the Oath also ceases...

“But if I have done the public any service this way, 'tis due to”

Newton to Bentley, 10 December 1692 (first letter), The Correspondence of Isaac Newton, ed. H. W. Turnbull (Cambridge: Cambridge University Press, 1961), 3:233. Referenced on p. 383 of Snobelen SD: " The Theology of Isaac Newton’s Principia Mathematica: A Preliminary Survey https://isaacnewtonstheology.files.wordpress.com/2013/06/theology-of-the-principia.pdf," pp. 377–412, Neue Zeitschrift für Systematische Theologie und Religionsphilosophie, Volume 52, Issue 4 (Jan 2010)
Context: When I wrote my treatise about our System, I had an eye upon such principles as might work with considering men for the belief of a Deity and nothing can rejoice me more than to find it useful for that purpose. But if I have done the public any service this way, 'tis due to nothing but industry and a patient thought.

“Christ comes as a thief in the night, & it is not for us to know the times & seasons which God hath put into his own breast.”

An Historical Account of Two Notable Corruptions of Scripture (1704), regarding his calculations "Of the End of the World" based upon the prophecies of Daniel, quoted in Look at the Moon! the Revelation Chronology (2007) by John A. Abrams, p. 141
Modern typographical and spelling variant:
This I mention not to assert when the time of the end shall be, but to put a stop to the rash conjectures of fanciful men who are frequently predicting the time of the end, and by doing so bring the sacred prophesies into discredit as often as their predictions fail.
As quoted in "The world will end in 2060, according to Newton" in the London Evening Standard (19 June 2007) http://www.thisislondon.co.uk/news/article-23401099-the-world-will-end-in-2060-according-to-newton.do
Context: The 2300 years do not end before the year 2132 nor after 2370.
The time times & half time do not end before 2060..... It may end later, but I see no reason for its ending sooner. This I mention not to assert when the time of the end shall be, but to put a stop to the rash conjectures of fancifull men who are frequently predicting the time of the end, & by doing so bring the sacred prophesies into discredit as often as their predictions fail. Christ comes as a thief in the night, & it is not for us to know the times & seasons which God hath put into his own breast.

“But it is not to be conceived that mere mechanical causes could give birth to so many regular motions”

Philosophiae Naturalis Principia Mathematica (1687), Scholium Generale (1713; 1726)
Context: But it is not to be conceived that mere mechanical causes could give birth to so many regular motions: since the Comets range over all parts of the heavens, in very eccentric orbits. For by that kind of motion they pass easily through the orbs of the Planets, and with great rapidity; and in their aphelions, where they move the slowest, and are detain'd the longest, they recede to the greatest distances from each other, and thence suffer the least disturbance from their mutual attractions.

“By the conversion of the ten kingdoms to the Roman religion, the Pope only enlarged his spiritual dominion, but did not yet rise up as a horn of the Beast. It was his temporal dominion which made him one of the horns: and this dominion he acquired in the latter half of the eighth century, by subduing three of the former horns as above.”

Vol. I, Ch. 8: Of the power of the eleventh horn of Daniel's fourth Beast, to change times and laws
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: While this Ecclesiastical Dominion was rising up, the northern barbarous nations invaded the Western Empire, and founded several kingdoms therein, of different religions from the Church of Rome. But these kingdoms by degrees embraced the Roman faith, and at the same time submitted to the Pope's authority. The Franks in Gaul submitted in the end of the fifth Century, the Goths in Spain in the end of the sixth; and the Lombards in Italy were conquered by Charles the great A. C. 774. Between the years 775 and 794, the same Charles extended the Pope's authority over all Germany and Hungary as far as the river Theysse and the Baltic sea; he then set him above all human judicature, and at the same time assisted him in subduing the City and Duchy of Rome. By the conversion of the ten kingdoms to the Roman religion, the Pope only enlarged his spiritual dominion, but did not yet rise up as a horn of the Beast. It was his temporal dominion which made him one of the horns: and this dominion he acquired in the latter half of the eighth century, by subduing three of the former horns as above. And now being arrived at a temporal dominion, and a power above all human judicature, he reigned with a look more stout than his fellows, and times and laws were henceforward given into his hands, for a time times and half a time, or three times and an half; that is, for 1260 solar years, reckoning a time for a Calendar year of 360 days, and a day for a solar year. After which the judgment is to sit, and they shall take away his dominion, not at once, but by degrees, to consume, and to destroy it unto the end. And the kingdom and dominion, and greatness of the kingdom under the whole heaven shall, by degrees, be given unto the people of the saints of the most High, whose kingdom is an everlasting kingdom, and all dominions shall serve and obey him.
