70. Let us now go further, and gather the truth in conclusion from arguments. For although arguments usually give place, even to human evidence, i.e. à priori determinations respecting any matter cannot be maintained if they are traversed by the statements of eye-witnesses and participators in the affair. still, heretic, argue as thou wilt. “Experience teaches us,” you say, “that the being which generates is prior to that which is generated.” I answer: Follow our customary experience through all its departments, and if the rest agree herewith, I oppose not your claim that your point be granted; but if there be no such agreement, how can you claim assent on this one point, when in all the rest you lack support? Seeing, then, that you call for what is customary, it comes about that the Son, when He was begotten of the Father, was a little child. You have seen Him an infant, crying in the cradle. As the years passed, He has gone forward from strength to strength—for if He was weak with the weakness of things begotten, He must also have fallen under the weakness, not only of birth, but of life also.
