Sir Isaac Newton - Charles Darwin

Sir Isaac Newton - Charles Darwin

Pick One

01. Sir Isaac Newton

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, "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."

His scientific fame notwithstanding, Newton's studies of the Bible and of the early Church Fathers were also noteworthy. Newton wrote works on textual criticism, most notably An Historical Account of Two Notable Corruptions of Scripture. He also placed the crucifixion of Jesus Christ at 3 April, AD 33, which agrees with one traditionally accepted date. He also attempted, unsuccessfully, to find hidden messages within the Bible.

In his own lifetime, Newton wrote more on religion than he did on natural science. He believed in a rationally immanent world, but he rejected the hylozoism implicit in Leibniz and Baruch Spinoza. Thus, 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". He saw evidence of design in the system of the world: "Such a wonderful uniformity in the planetary system must be allowed the effect of choice". But Newton insisted that divine intervention would eventually be required to reform the system, due to the slow growth of instabilities. For this Leibniz lampooned him: "God Almighty wants to wind up his watch from time to time: otherwise it would cease to move. 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.

02. Charles Darwin

Darwin’s family tradition was nonconformist Unitarianism, while his father and grandfather were freethinkers, and his baptism and boarding school were Church of England. When going to Cambridge to become an Anglican clergyman, he did not doubt the literal truth of the Bible. He learnt John Herschel's science which, like William Paley’s natural theology, sought explanations in laws of nature rather than miracles and saw adaptation of species as evidence of design. On board the Beagle, Darwin was quite orthodox and would quote the Bible as an authority on morality. He looked for "centres of creation" to explain distribution, and related the antlion found near kangaroos to distinct "periods of Creation".

By his return he was critical of the Bible as history, and wondered why all religions should not be equally valid. In the next few years, while intensively speculating on geology and transmutation of species, he gave much thought to religion and openly discussed this with Emma, whose beliefs also came from intensive study and questioning. The theodicy of Paley and Thomas Malthus vindicated evils such as starvation as a result of a benevolent creator's laws which had an overall good effect. To Darwin, natural selection produced the good of adaptation but removed the need for design, and he could not see the work of an omnipotent deity in all the pain and suffering such as the ichneumon wasp paralysing caterpillars as live food for its eggs. He still viewed organisms as perfectly adapted, and On the Origin of Species reflects theological views. Though he thought of religion as a tribal survival strategy, Darwin still believed that God was the ultimate lawgiver.

Darwin continued to play a leading part in the parish work of the local church, but from around 1849 would go for a walk on Sundays while his family attended church. Though reticent about his religious views, in 1879 he responded that he had never been an atheist in the sense of denying the existence of a God, and that generally “an Agnostic would be the more correct description of my state of mind.”
