Isaac Newton

Sir Isaac Newton was an English scientist who lived from 1634 to 1727. Newton was a physicist, astronomer, mathematician, alchemist, and government official. He is best known for his Theory of Universal Gravitation and his Laws of Motion. He also developed calculus for the purpose of his work in physics. In addition, Newton invented the reflecting telescope, and made numerous other contributions to his fields of study.

Newton was the first to demonstrate that the same laws that govern the motion of celestial objects also govern the motion of things on Earth. Newton contributed greatly to the advancement of science. His work also advanced the concept of heliocentrism (the view that the Sun is at the center of the solar system).

Newton's view of science was that far more remained undiscovered. "I do not know what I may appear to the world; but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me."

In 1705, in recognition of Isaac Newton's role as master of the Mint, Queen Anne knighted him. It was the first knighthood to be given for scientific achievement rather than prowess on the battlefield or work in government.

Newton is often seen as one of the most influential men in all of history and perhaps the greatest scientist ever. His work was influential even in philosophy, as he inspired Kant to create the philosophical concepts of the categorical imperative and the synthetic a priori.

After his death and burial, Newton was exhumed so he could be buried in a more prominent location in Westminster Abbey. During this exhumation process, it was discovered that Newton had large amounts of mercury in his body, probably as a direct result of his alchemical experiments. Exposure to large amounts of mercury may explain Newton’s eccentricity in his latter years, as well as his cause of death.

Gravity

Newton developed the Theory of Universal Gravitation, more commonly known as gravity, when, according to legend, a falling apple struck him on the head. He realized that the same force that pulled the apple to the ground could be what keeps Jupiter's moons in orbit. His theory stated that all matter is attracted to matter by a force, whose strength increases proportionally to the mass of the objects involved, and inversely proportional to the squared distance between them. Newton's theory is based on action-at-a-distance which has always been opposed by some scientists, and now most physicists endorse the very different theory of relativity. Both theories predict identical results at small scales, similar results at the scale of the solar system and very different results at cosmological scales beyond the solar system.

Religious Beliefs

Newton was an Arian who rejected the Trinity and was ambiguous about the divinity of Christ. As his leading biographer concludes, "Well before 1675, Newton had become an Arian in the original sense of the term." That is, he emphasized the powers of God the father and deemphasized Jesus. He considered himself a Christian who accepted the Bible as the Word of God, after the age of 25 he devoted much--perhaps most--of his thinking to religion. His unorthodox views violated the rules at Cambridge University, but his colleagues protected him.

Newton was a sincere religious believer, who said his discoveries were inspired by God. He devoted more time to the study of Scripture than to science. Newton wrote, "This most beautiful system of the sun, planets, and comets, could only proceed from the counsel and dominion of an intelligent Being... All variety of created objects which represent order and life in the universe could happen only by the willful reasoning of its original Creator, Whom I call the Lord God."

Newton believed that God's creation of the universe was self evident given its grandeur. He also warned against using his laws to replace the creator. He said, "Gravity explains the motions of the planets, but it cannot explain who set the planets in motion. God governs all things and knows all that is or can be done."

Newton wrote over a million words on religion--nealy all in unpublished hand-written manuscripts and unavailable for research until the 20th century. Although older scholars did not have access to his writings, "Among contemporary scholars, the consensus is that Newton was an Arian," concludes Pfizenmaier (1997).

Some older biographers without access to the manuscroipts have speculated, without justification, that Newton's views would today be considered those of a Unitarian, or an Arian. Those who reject Christ's divinity claim without justification that Newton likewise rejected it. The quotations of Newton that they cite say no such thing.

However, the evidence for Newton holding to Arianism is scant. It is true that Newton held a lot to himself, but to say that because of his association with William Whiston, that he is therefore an Arianist is hardly conclusive. It is more probable that Newton held to an Eastern Orthodox view of the Trinity.

John Conduitt, the husband of Newton's niece had this to say about Newton's theology.

"I had no hesitation when writing the Like of Sir Isaac Newton in 1830, in coming to the conclusions that he was a believer in the Trinity; and in giving this opinion on the creed of so great a man, and so indefatigable a student of scripture, I was well aware that there are various forms of Trinitarian truth, and various modes of expressing it, which have been received as orthodox in the purest societies of the Christian Church."

In an effort to debunk widespread claims of his time that the world would be ending soon, Newton wrote a private manuscript estimating that the world would not end prior to the year A.D. 2060.
