First they established the truth of the proposition by various observations. For instance, that man is born without any knowledge, not even that of conjugial love. They made enquiry and learned from researchers that a baby does not even know by instinct how to approach its mother's breast, but has to be positioned by its mother or nurse; it only knows how to suck, and that is because it has learned this by continually sucking in its mother's womb. Later on, it does not know how to walk; or how to adapt the sounds it makes to form a word of human speech, not even how to express its emotions by sounds as animals do. Moreover, it does not know what food is suitable for it, as all animals do, but grabs anything it finds, whether clean or dirty, and puts it in its mouth. The researchers reported that without instruction man does not know how to distinguish the sexes, and has no knowledge at all of how to make love. Not even young men and women know about this without being told by others, although they have been trained in various skills. In short, a man is by birth merely bodily, like a worm; and he remains bodily, unless he learns from others how to know, understand and be wise.

[2] Then they established that both the higher and lower animals, land animals, birds of the air, reptiles, fish and insects are born knowing all that their loves require for their lives; for instance, everything they need to know about feeding, about where to live, how to copulate and produce young, and how to bring up their young. They established these facts by remarkable observations which they recalled to mind from what they had seen, heard and read in the natural world - as they called our world where they had previously lived - where the animals which exist are not representative but real. When they had fully proved the truth of this proposition, they turned their minds to seeking and finding the purposes and reasons which would explain and elucidate this question. They all asserted that these facts must be the result of divine wisdom, to ensure that human beings were human and that animals were animals. Thus the imperfections with which a man is born would become his perfection, and the perfection with which an animal is born would become its imperfection.
