Belief in God
Is belief in the existence of God irrational? These days, many famous scientists are also strong proponents of atheism. However, in the past, and even today, many scientists believe that God exists and is responsible for what we see in nature. This is a small sampling of scientists who contributed to the development of modern science while believing in God. Although many people believe in a "God of the gaps", these scientists, and still others alive today, believe because of the evidence.
Nicholas Copernicus (1473-1543)
Copernicus was the Polish astronomer who put forward the first mathematically based system of planets going around the sun. He attended various European universities, and became a Canon in the Catholic church in 1497. His new system was actually first presented in the Vatican gardens in 1533 before Pope Clement VII who approved, and urged Copernicus to publish it around this time. Copernicus was never under any threat of religious persecution - and was urged to publish both by Catholic Bishop Guise, Cardinal Schonberg, and the Protestant Professor George Rheticus. Copernicus referred sometimes to God in his works, and did not see his system as in conflict with the Bible.
Sir Francis Bacon (1561-1627)
Bacon was a philosopher who is known for establishing the scientific method of inquiry based on experimentation and inductive reasoning. In De Interpretatione Naturae Prooemium, Bacon established his goals as being the discovery of truth, service to his country, and service to the church. Although his work was based upon experimentation and reasoning, he rejected atheism as being the result of insufficient depth of philosophy, stating, "It is true, that a little philosophy inclineth man’s mind to atheism, but depth in philosophy bringeth men's minds about to religion; for while the mind of man looketh upon second causes scattered, it may sometimes rest in them, and go no further; but when it beholdeth the chain of them confederate, and linked together, it must needs fly to Providence and Deity." (Of Atheism)
Johannes Kepler (1571-1630)
Kepler was a brilliant mathematician and astronomer. He did early work on light, and established the laws of planetary motion about the sun. He also came close to reaching the Newtonian concept of universal gravity - well before Newton was born! His introduction of the idea of force in astronomy changed it radically in a modern direction. Kepler was an extremely sincere and pious Lutheran, whose works on astronomy contain writings about how space and the heavenly bodies represent the Trinity. Kepler suffered no persecution for his open avowal of the sun-centered system, and, indeed, was allowed as a Protestant to stay in Catholic Graz as a Professor (1595-1600) when other Protestants had been expelled!
Galileo Galilei (1564-1642)
Galileo is often remembered for his conflict with the Roman Catholic Church. His controversial work on the solar system was published in 1633. It had no proofs of a sun-centered system (Galileo's telescope discoveries did not indicate a moving earth) and his one "proof" based upon the tides was invalid. It ignored the correct elliptical orbits of planets published twenty five years earlier by Kepler. Since his work finished by putting the Pope's favorite argument in the mouth of the simpleton in the dialogue, the Pope (an old friend of Galileo's) was very offended. After the "trial" and being forbidden to teach the sun-centered system, Galileo did his most useful theoretical work, which was on dynamics. Galileo expressly said that the Bible cannot err, and saw his system as an alternate interpretation of the biblical texts.
Rene Descartes (1596-1650)
Descartes was a French mathematician, scientist and philosopher who has been called the father of modern philosophy. His school studies made him dissatisfied with previous philosophy: He had a deep religious faith as a Roman Catholic, which he retained to his dying day, along with a resolute, passionate desire to discover the truth. At the age of 24 he had a dream, and felt the vocational call to seek to bring knowledge together in one system of thought. His system began by asking what could be known if all else were doubted - suggesting the famous "I think therefore I am". Actually, it is often forgotten that the next step for Descartes was to establish the near certainty of the existence of God - for only if God both exists and would not want us to be deceived by our experiences - can we trust our senses and logical thought processes. God is, therefore, central to his whole philosophy. What he really wanted to see was that his philosophy be adopted as standard Roman Catholic teaching. Rene Descartes and Francis Bacon (1561-1626) are generally regarded as the key figures in the development of scientific methodology. Both had systems in which God was important, and both seem more devout than the average for their era.
Blaise Pascal (1623-1662)
