Religion and science

Religious knowledge, according to religious practitioners, may be gained from religious leaders, sacred texts (scriptures), and/or personal revelation. Some religions view such knowledge as unlimited in scope and suitable to answer any question; others see religious knowledge as playing a more restricted role, often as a complement to knowledge gained through physical observation. Some religious people maintain that religious knowledge obtained in this way is absolute and infallible religious cosmology.

The scientific method gains knowledge by testing hypotheses to develop theories through elucidation of facts or evaluation by experiments and thus only answers cosmological questions about the physical universe. It develops theories of the world which best fit physically observed evidence. All scientific knowledge is subject to later refinement in the face of additional evidence. Scientific theories that have an overwhelming preponderance of favorable evidence are often treated as facts such as the theories of gravity or evolution.

Early science such as geometry and astronomy was connected to the divine for most medieval scholars. The compass in this 13th century manuscript is a symbol of God's act of creation.
Many scientists have held strong religious beliefs (see List of Christian thinkers in science) and have worked to harmonize science and religion. Isaac Newton, for example, believed that gravity caused the planets to revolve about the Sun, and credited God with the design. In the concluding General Scholium to the Philosophiae Naturalis Principia Mathematica, he wrote: "This most beautiful System of the Sun, Planets and Comets, could only proceed from the counsel and dominion of an intelligent and powerful being." Nevertheless, conflict has repeatedly arisen between religious organizations and individuals who propagated scientific theories that were deemed unacceptable by the organizations. The Roman Catholic Church, for example, has in the past reserved to itself the right to decide which scientific theories were acceptable and which were unacceptable. In the 17th century, Galileo was tried and forced to recant the heliocentric theory based on the church's stance that the Greek Hellenistic system of astronomy was the correct one.Today, however, only 7% of the members of the National Academy of Sciences believe in a god.
