All thinkers, in all lands and in all times, have assumed the necessity for postulating the existence of this Substantial Reality. All philosophies worthy of the name have been based upon this thought. Men have given to this Substantial Reality many names—some have called it by the term of Deity (under many titles); others have called it “The Infinite and Eternal Energy”; others have tried to call it “Matter”—but all have acknowledged its existence. It is self-evident—it needs no argument.
