Introduction to Philosophy may be described as an attempt to state naturalism as to make it harminoously continuous with the religious faith. The author does not believe in a philosophy that is philosophy of human mind. It is impossible to seperate philosophy from the natural sciences. But the natural sciences left to themselves have more and more drifted towards an atomistic materalism. There can be no conflict between science and religion. The task of science is to trace the facts, that of religions are to declare the system of values which they form or to measure their teleological expressiveness. The author makes both philosophy and life continuous. Life lies open and the philosophy must wear the form of closed system and no philosophy can be more than a hypothesis.
