It has become customary in the West to think of science and religion as occupying two distinct -- and even opposed -- areas of human thought and activity. This dichotomy can be characterized in the pairs of antitheses: faith and reason; value and fact. It is a dichotomy which is foreign to Bahá'í thought…. The principle of the harmony of science and religion means not only that religious teachings should be studied with the light of reason and evidence as well as of faith and inspiration, but also that everything in this creation, all aspects of human life and knowledge, should be studied in the light of revelation as well as in that of purely rational investigation. In other words… when studying a subject, [one] should not lock out of his mind any aspect of truth that is known to him.
