Isaac Newton Quotes
Why there is one body in our System qualified to give light and heat to all the rest, I know no reason but because the Author of the System thought it convenient; and why there is but one body of this kind, I know no reason, but because one was sufficient to warm and enlighten all the rest.
Newton, Isaac. Letter to Richard Bentley, 10 Dec. 1692. The Correspondence of Isaac Newton, edited by H.W. Turnbull, vol. 3, Cambridge UP, 1961, p. 233.
The Roman Catholic Church had stultified scientific thinking for over a thousand years where differing with accepted church doctrine was not only discouraged but was dangerous. Hicletas—see {590328}—realized that the earth rotated around its own axis three centuries before Christ, and his view was in the literature to which learned people had access. Copernicus later communicated this idea to the Pope but in much more delicate terms—see {590327}. He did not have the problems that Galileo endured with the Church for several reasons. There were different men controlling the church, the printing press had been invented and Galileo published a book that many could read, the Protestant Reformation had really frightened the Church fathers who felt more vulnerable and less tolerant.
Sir Isaac Newton PRS was an English mathematician, physicist, astronomer, theologian, and author (described in his time as a "natural philosopher") who is widely recognised as one of the greatest mathematicians and most influential scientists of all time and as a key figure in the scientific revolution. His book Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687, established classical mechanics. Newton also made seminal contributions to optics, and shares credit with Gottfried Wilhelm Leibniz for developing the infinitesimal calculus.
