The first of the realities with which we will deal is Time. It is the fashion with some metaphysical writers to assert that there is no time; but the arguments advanced in support of this claim are superficial. Time is not an entity having substance, but it is an existing reality, nevertheless. Time is not an idea; a fiction by which we measure and record the motions of the heavenly bodies; time would go on just the same and at exactly the same rate if the heavenly bodies were motionless. Do not misunderstand me in my use of the word “time.” Many people suppose that time began when man began, and must end when man ends as a mortal and physical being, and that the periods before and after the earth life of the human race are to be called eternities; in other words that there can be no time except so long as there is a mortal man to measure it; but this is erroneous. Days, weeks, months and years must have gone on before man came on earth, just as they do now; and if man disappeared from the earth, they would still go on. If the earth ceased to revolve around the sun, and to turn on its axis, the succession of the seasons and of day and night would cease; day would be continuous on one side of the earth, and night upon the other, but hours and minutes would go on just the same, and if the sun, moon, planets, stars and all else were to disappear and be succeeded by black, silent, formless chaos, hours and minutes would go on forever. Clocks do not make time; an hour would have the same duration if there were no clocks. In eternity there must still be time; time is duration in eternity. Eternity is endless time. Time can never end. If you try to think of a point at which time should end, you can only think of it as a point beyond which there must be still more time. Also, then, time can never have had a beginning; for if you try to think of a point at which time began, you can only think of it as a point beyond which there must have been still more time. Do not say that endless time is unthinkable; you can very easily think endless time, if you do not try to think of the end of it. You cannot _comprehend_ endless time, for that means to contain it in your mind, or to go around it; but you can know what it is, and you can know that it is.
