Anthropology does not show that. That is part of the evolutionary guess. There is no scientific evidence whatever as to what degree of culture the first man possessed. Meantime it is certain that Adam had all the knowledge necessary and fitting for his circumstances. Genesis shows us that he knew the nature and diversity of animals, whilst Ecclesiasticus XVII., 5-6, tells us that God filled him with knowledge and understanding, and created in our first parents science and wisdom. The fact of their knowledge must be admitted. Its degree is open to speculation, but in no way can we admit that our first parents were demi-witted, nor can science possibly demonstrate such a deficiency.
