Newton "recognized Christ as a divine mediator between God and man, who was subordinate to the Father who created him. Newton tried unsuccessfully to obtain one of the two fellowships that exempted the holder from the ordination requirement.
At the last moment in he received a dispensation from the government that excused him and all future holders of the Lucasian chair. In Newton's eyes, worshipping Christ as God was idolatry , to him the fundamental sin.
Snobelen wrote, "Isaac Newton was a heretic. He hid his faith so well that scholars are still unraveling his personal beliefs. In a minority position, T.
Pfizenmaier offers a more nuanced view, arguing that Newton held closer to the Semi-Arian view of the Trinity that Jesus Christ was of a "similar substance" homoiousios from the Father rather than the orthodox view that Jesus Christ is of the "same substance" of the Father homoousios as endorsed by modern Eastern Orthodox, Roman Catholics and Protestants.
Although the laws of motion and universal gravitation became Newton's best-known discoveries, he warned against using them to view the Universe as a mere machine, as if akin to a great clock.
He said, "So then 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".
Along with his scientific fame, Newton's studies of the Bible and of the early Church Fathers were also noteworthy. He believed in a rationally immanent world, but he rejected the hylozoism implicit in Leibniz and Baruch Spinoza.
The ordered and dynamically informed Universe could be understood, and must be understood, by an active reason. In his correspondence, Newton claimed that in writing the Principia "I had an eye upon such Principles as might work with considering men for the belief of a Deity".
But Newton insisted that divine intervention would eventually be required to reform the system, due to the slow growth of instabilities.
He had not, it seems, sufficient foresight to make it a perpetual motion. Newton's position was vigorously defended by his follower Samuel Clarke in a famous correspondence.
A century later, Pierre-Simon Laplace 's work Celestial Mechanics had a natural explanation for why the planet orbits do not require periodic divine intervention.
Scholars long debated whether Newton disputed the doctrine of the Trinity. His first biographer, Sir David Brewster , who compiled his manuscripts, interpreted Newton as questioning the veracity of some passages used to support the Trinity, but never denying the doctrine of the Trinity as such.
Newton and Robert Boyle 's approach to the mechanical philosophy was promoted by rationalist pamphleteers as a viable alternative to the pantheists and enthusiasts , and was accepted hesitantly by orthodox preachers as well as dissident preachers like the latitudinarians.
The attacks made against pre- Enlightenment " magical thinking ", and the mystical elements of Christianity , were given their foundation with Boyle's mechanical conception of the universe.
Newton gave Boyle's ideas their completion through mathematical proofs and, perhaps more importantly, was very successful in popularising them.
In a manuscript he wrote in never intended to be published , he mentions the date of , but it is not given as a date for the end of days.
It has been falsely reported as a prediction. He was against date setting for the end of days, concerned that this would put Christianity into disrepute.
And the days of short lived Beasts being put for the years of [long-]lived kingdoms the period of days, if dated from the complete conquest of the three kings A.
It may end later, but I see no reason for its ending sooner. Christ comes as a thief in the night, and it is not for us to know the times and seasons which God hath put into his own breast.
Few remember that he spent half his life muddling with alchemy, looking for the philosopher's stone. That was the pebble by the seashore he really wanted to find.
Of an estimated ten million words of writing in Newton's papers, about one million deal with alchemy. Many of Newton's writings on alchemy are copies of other manuscripts, with his own annotations.
In , after spending sixteen years cataloguing Newton's papers, Cambridge University kept a small number and returned the rest to the Earl of Portsmouth.
In , a descendant offered the papers for sale at Sotheby's. Keynes went on to reassemble an estimated half of Newton's collection of papers on alchemy before donating his collection to Cambridge University in All of Newton's known writings on alchemy are currently being put online in a project undertaken by Indiana University : "The Chymistry of Isaac Newton"  and summarised in a book.
Newton's fundamental contributions to science include the quantification of gravitational attraction, the discovery that white light is actually a mixture of immutable spectral colors, and the formulation of the calculus.
Yet there is another, more mysterious side to Newton that is imperfectly known, a realm of activity that spanned some thirty years of his life, although he kept it largely hidden from his contemporaries and colleagues.
We refer to Newton's involvement in the discipline of alchemy, or as it was often called in seventeenth-century England, "chymistry.
Charles Coulston Gillispie disputes that Newton ever practised alchemy, saying that "his chemistry was in the spirit of Boyle's corpuscular philosophy.
In June , two unpublished pages of Newton's notes on Jan Baptist van Helmont 's book on plague, De Peste  , were being auctioned online by Bonham's.
Newton's analysis of this book, which he made in Cambridge while protecting himself from London's infection , is the most substantial written statement he is known to have made about the plague, according to Bonham's.
As far as the therapy is concerned, Newton writes that "the best is a toad suspended by the legs in a chimney for three days, which at last vomited up earth with various insects in it, on to a dish of yellow wax, and shortly after died.
Combining powdered toad with the excretions and serum made into lozenges and worn about the affected area drove away the contagion and drew out the poison".
Enlightenment philosophers chose a short history of scientific predecessors—Galileo, Boyle, and Newton principally—as the guides and guarantors of their applications of the singular concept of nature and natural law to every physical and social field of the day.
In this respect, the lessons of history and the social structures built upon it could be discarded. It was Newton's conception of the universe based upon natural and rationally understandable laws that became one of the seeds for Enlightenment ideology.
Monboddo and Samuel Clarke resisted elements of Newton's work, but eventually rationalised it to conform with their strong religious views of nature.
Newton himself often told the story that he was inspired to formulate his theory of gravitation by watching the fall of an apple from a tree.
Although it has been said that the apple story is a myth and that he did not arrive at his theory of gravity at any single moment,  acquaintances of Newton such as William Stukeley , whose manuscript account of has been made available by the Royal Society do in fact confirm the incident, though not the apocryphal version that the apple actually hit Newton's head.
John Conduitt , Newton's assistant at the Royal Mint and husband of Newton's niece, also described the event when he wrote about Newton's life: .
In the year he retired again from Cambridge to his mother in Lincolnshire. Whilst he was pensively meandering in a garden it came into his thought that the power of gravity which brought an apple from a tree to the ground was not limited to a certain distance from earth, but that this power must extend much further than was usually thought.
It is known from his notebooks that Newton was grappling in the late s with the idea that terrestrial gravity extends, in an inverse-square proportion, to the Moon; however, it took him two decades to develop the full-fledged theory.
Newton showed that if the force decreased as the inverse square of the distance, one could indeed calculate the Moon's orbital period, and get good agreement.
He guessed the same force was responsible for other orbital motions, and hence named it "universal gravitation".
Various trees are claimed to be "the" apple tree which Newton describes. The King's School, Grantham claims that the tree was purchased by the school, uprooted and transported to the headmaster's garden some years later.
The staff of the now National Trust -owned Woolsthorpe Manor dispute this, and claim that a tree present in their gardens is the one described by Newton.
A descendant of the original tree  can be seen growing outside the main gate of Trinity College, Cambridge, below the room Newton lived in when he studied there.
The National Fruit Collection at Brogdale in Kent  can supply grafts from their tree, which appears identical to Flower of Kent , a coarse-fleshed cooking variety.

By June , he was ready to matriculate at Trinity College , Cambridge , somewhat older than the other undergraduates because of his interrupted education.
When Newton arrived in Cambridge in , the movement now known as the Scientific Revolution was well advanced, and many of the works basic to modern science had appeared.
Astronomers from Copernicus to Kepler had elaborated the heliocentric system of the universe. Galileo had proposed the foundations of a new mechanics built on the principle of inertia.
Led by Descartes , philosophers had begun to formulate a new conception of nature as an intricate, impersonal, and inert machine.
Yet as far as the universities of Europe, including Cambridge, were concerned, all this might well have never happened. They continued to be the strongholds of outmoded Aristotelianism , which rested on a geocentric view of the universe and dealt with nature in qualitative rather than quantitative terms.
Even though the new philosophy was not in the curriculum, it was in the air. He had thoroughly mastered the works of Descartes and had also discovered that the French philosopher Pierre Gassendi had revived atomism , an alternative mechanical system to explain nature.
Significantly, he had read Henry More , the Cambridge Platonist, and was thereby introduced to another intellectual world, the magical Hermetic tradition, which sought to explain natural phenomena in terms of alchemical and magical concepts.
The two traditions of natural philosophy, the mechanical and the Hermetic, antithetical though they appear, continued to influence his thought and in their tension supplied the fundamental theme of his scientific career.
He then reached back for the support of classical geometry. Within little more than a year, he had mastered the literature; and, pursuing his own line of analysis, he began to move into new territory.
He discovered the binomial theorem , and he developed the calculus , a more powerful form of analysis that employs infinitesimal considerations in finding the slopes of curves and areas under curves.
On his own, without formal guidance, he had sought out the new philosophy and the new mathematics and made them his own, but he had confined the progress of his studies to his notebooks.
Then, in , the plague closed the university, and for most of the following two years he was forced to stay at his home, contemplating at leisure what he had learned.
It was during this time that he examined the elements of circular motion and, applying his analysis to the Moon and the planets , derived the inverse square relation that the radially directed force acting on a planet decreases with the square of its distance from the Sun —which was later crucial to the law of universal gravitation.
