"Is it possible that one should be a theist in respect of belief while his acts do not reflect his faith, being, in practice, a materialist? Further, is it possible that a person be doctrinally a materialist, without being a materialist in practice, i.e. with a life free from and uncorrupted by excesses, transgression, and tyrannical behavior? Finally, is it possible for moral materialism to exist in isolation from doctrinal materialism? The answer is: Yes, it is possible, and occurs often, though it is not something which may last for long, or which can be counted upon. That is because it is an unnatural condition and that which is against nature and the natural order of cause and effect cannot survive for long. Further, wherever this separation exists, either behavior influences belief and alters it, or belief and ideals make their impact and alter the mode of behavior. As a result either faith gives in to behavior or behavior subdues faith. It is hard to believe that someone can remain a theist all his life doctrinally and intellectually, while being a materialist in practice. Eventually one of the two sides will subdue the other and he will perforce incline towards one of them."
