Chapter six, Science and Religion, is a brief, general introduction to the two topics. In the text, evolution is termed a grand theory, one in which many fundamental principles act in concert to create a complex phenomenon. The scientific method is described as the best way to separate fact from opinion. The various branches of science are briefly described. The text considers religion to be a belief in a divine or superhuman power or powers to be obeyed and worshiped as the creator(s) and ruler(s) of the universe, a belief that meets the needs of the culture that subscribes to it. It is a construct of humans (though all religions dispute that) seeking to understand our relationship with the Creator. The text identifies a set of eight general traits, such as the way to gain a good everlasting life, that characterize all religions, from the primitive beliefs of the ancients to modern faiths.
