beginning, and is limited by some termination, be it of what extent it may, if you compare it with that which has no beginning, I know not whether to say we should count it the very minutest thing, or nothing at all. For, take this limited time, and deduct from the end of it, one by one, the briefest moments (as you might take day by day from a man's life, beginning at the day in which he now lives, back to that of his birth), and though the number of moments you must subtract in this backward movement be so great that no word can express it, yet this subtraction will some time carry you to the beginning. But if you take away from a time which has no beginning, I do not say brief moments one by one, nor yet hours, or days, or months, or years even in quantities, but terms of years so vast that they cannot be named by the most skilful arithmetician,—take away terms of years as vast as that which we have supposed to be gradually consumed by the deduction of moments,—and take them away not once and again repeatedly, but always, and what do you effect, what do you make by your deduction, since you never reach the beginning which has no existence? Wherefore, that which we now demand after five thousand odd years, our descendants might with like curiosity demand after six hundred thousand years, supposing these dying generations of men continue so long to decay and be renewed, and supposing posterity continues as weak and ignorant as ourselves. The same question might have been asked by those who have lived before us, and while man was even newer upon earth. The first man himself, in short, might, the day after, or the very day of his creation, have asked why he was created no sooner. And no matter at what earlier or later period he had been created, this controversy about the commencement of this world's history would have had precisely the same difficulties as it has now.
