“No man hath seen God at any time, if we love one another God dwelleth in us. — If a man say I love God & hateth his brother he is a liar: for he that loveth not his brother whom he hath seen how can he love God whom he hath not seen?”

A short Schem of the true Religion

“In the beginning of the year 1665 I found the method of approximating Series and the Rule for reducing any dignity of any Binomial into such a series. The same year in May I found the method of tangents of Gregory and Slusius, and in November had the direct method of Fluxions, and the next year in January had the Theory of Colours, and in May following I had entrance into the inverse method of Fluxions. And the same year I began to think of gravity extending to the orb of the Moon, and having found out how to estimate the force with which [a] globe revolving within a sphere presses the surface of the sphere, from Kepler's Rule of the periodical times of the Planets being in a sesquialterate proportion of their distances from the centers of their orbs I deduced that the forces which keep the Planets in their Orbs must [be] reciprocally as the squares of their distances from the centers about which they revolve: and thereby compared the force requisite to keep the Moon in her orb with the force of gravity at the surface of the earth, and found them answer pretty nearly. All this was in the two plague years of 1665 and 1666, for in those days I was in the prime of my age for invention, and minded Mathematicks and Philosophy more than at any time since. What Mr Hugens has published since about centrifugal forces I suppose he had before me. At length in the winter between the years 1676 and 1677 I found the Proposition that by a centrifugal force reciprocally as the square of the distance a Planet must revolve in an Ellipsis about the center of the force placed in the lower umbilicus of the Ellipsis and with a radius drawn to that center describe areas proportional to the times. And in the winter between the years 1683 and 1684 this Proposition with the Demonstration was entered in the Register book of the R. Society. And this is the first instance upon record of any Proposition in the higher Geometry found out by the method in dispute. In the year 1689 Mr Leibnitz, endeavouring to rival me, published a Demonstration of the same Proposition upon another supposition, but his Demonstration proved erroneous for want of skill in the method.”

Also partially quoted in Sir Sidney Lee (ed.), The Dictionary of National Biography Vol.40 http://books.google.com/books?id=NycJAAAAIAAJ (1894)

“The Ellipse is the most simple of the Conic Sections, most known, and nearest of Kin to a Circle, and easiest describ'd by the Hand in plano. Though many prefer the Parabola before it, for the Simplicity of the Æquation by which it is express'd. But by this Reason the Parabola ought to be preferr'd before the Circle it self, which it never is. Therefore the reasoning from the Simplicity of the Æquation will not hold. The modern Geometers are too fond of the Speculation of Æquations.”

“The second and third Empires, represented by the Bear and Leopard, are again represented by the Ram and He-Goat; but with this difference, that the Ram represents the kingdoms of the Medes and Persians from the beginning of the four Empires, and the Goat represents the kingdom of the Greeks to the end of them. By this means, under the type of the Ram and He-Goat, the times of all the four Empires are again described: I lifted up mine eyes, saith Daniel, and saw, and behold there stood before the river [Ulai] a Ram which had two horns, and the two horns were high, but one was higher than the other, and the higher came up last.”

“Is not this Medium [æther] much rarer within the dense Bodies of the Sun, Stars, Planets, and Comets, than in the empty celestial Spaces between them? And in passing from them to great distances, doth it not grow denser and denser perpetually, and thereby cause the gravity of those great Bodies towards one another, and of their parts towards the Bodies; every Body endeavouring to go from the denser parts of the Medium towards the rarer? …And though this Increase of density may at great distances be exceeding stow, yet if the elastick force of this Medium be exceeding great, it may suffice to impel Bodies from the denser parts of the Medium towards the rarer, with all that power which we call Gravity. And that the elastic force of this Medium is exceeding great, may be gather'd from the swiftness of its Vibrations.”

Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Contexto: 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.

Isaac Newton

Reported as Newton's response, whenever Edmond Halley would say anything disrespectful of religion, by Sir David Brewster in The Life of Sir Isaac Newton (1831). This has often been quoted in recent years as having been a statement specifically defending Astrology. Newton wrote extensively on the importance of Prophecy, and studied Alchemy, but there is little evidence that he took favourable notice of astrology http://www.staff.science.uu.nl/~gent0113/astrology/newton.htm. In a footnote, Brewster attributes the anecdote to the astronomer Nevil Maskelyne who is said to have passed it on to Oxford professor Stephen Peter Rigaud http://books.google.co.uk/books?id=gLcVAAAAYAAJ&pg=PA301&lpg=PA301&dq=brewster+newton+%22I+have+studied%22&source=bl&ots=dEwk6nHcSa&sig=F2uReuXjRWwL3w647pfaU1PlbC0&hl=en&sa=X&ei=fqu5UpzkAvOA7Qap9oGoDQ&ved=0CGoQ6AEwBw#v=onepage&q=brewster%20newton%20%22I%20have%20studied%22&f=false

“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. Yet the thing is not altogether desperate; for we have some arguments to guide us, partly from the apparent motions, which are the differences of the true motions; partly from the forces, which are the causes and effects of the true motions.”

I frame no hypotheses.

A famous statement in the "General Scholium" of the third edition, indicating his belief that the law of universal gravitation was a fundamental empirical law, and that he proposed no hypotheses on how gravity could propagate.

Variant translation: I feign no hypotheses.

As translated by Alexandre Koyré (1956)

I have not as yet been able to discover the reason for these properties of gravity from phenomena, and I do not feign hypotheses. For whatever is not deduced from the phenomena must be called a hypothesis; and hypotheses, whether metaphysical or physical, or based on occult qualities, or mechanical, have no place in experimental philosophy. In this philosophy particular propositions are inferred from the phenomena, and afterwards rendered general by induction.

“The Vision of the Image composed of four Metals was given first to Nebuchadnezzar, and then to Daniel in a dream: and Daniel began then to be celebrated for revealing of secrets, Ezek. xxviii. 3. The Vision of the four Beasts, and of the Son of man coming in the clouds of heaven, was also given to Daniel in a dream. That of the Ram and the He-Goat appeared to him in the day time, when he was by the bank of the river Ulay; and was explained to him by the prophetic Angel Gabriel. It concerns the Prince of the host, and the Prince of Princes: and now in the first year of Darius the Mede over Babylon, the same prophetic Angel appears to Daniel again, and explains to him what is meant by the Son of man, by the Prince of the host, and the Prince of Princes.”
