in the female's blood when still included in its vessels: its nature is different from what it was in the moment of conception, when it is met by the semen of the male and begins to develop: the properties of the semen in that moment are different from the properties of the living being after its birth when fully developed. It is therefore quite impossible to infer from the nature which a thing possesses after having passed through all stages of its development, what the condition of the thing has been in the moment when this process commenced: nor does the condition of a thing in this moment show what its previous condition has been. If you make this mistake, and attempt to prove the nature of a thing in potential existence by its properties when actually existing, you will fall into great confusion: you will reject evident truths and admit false opinions. Let us assume, in our above instance, that a man born without defect had after his birth been nursed by his mother only a few months; the mother then died, and the father alone brought him up in a lonely island, till he grew up, became wise, and acquired knowledge. Suppose this man has never seen a woman or any female being: he asks some person how man has come into existence, and how he has developed, and receives the following answer:" Man begins his existence in the womb of an individual of his own class, namely, in the womb of a female, which has a certain form. While in the womb he is very small; yet he has life, moves, receives nourishment, and gradually grows, till he arrives at a certain stage of development. He then leaves the womb and continues to grow till he is in the condition in which you see him." The orphan will naturally ask:" Did this person, when he lived, moved, and grew in the womb, eat and drink, and breathe with his mouth and his nostrils? Did he excrete any substance?" The answer will be," No." Undoubtedly he will then attempt to refute the statements of that person, and to prove their impossibility, by referring to the properties of a fully developed person, in the following manner:" When any one of us is deprived of breath for a short time he dies, and cannot move any longer: how then can we imagine that any one of us has been enclosed in a bag in the midst of a body for several months and remained alive, able to move? If any one of us would swallow a living bird, the bird would die immediately when it reached the stomach, much more so when it came to the lower part of the belly; if we should not take food or drink with our mouth, in a few days we should undoubtedly be dead: how then can man remain alive for months without taking food? If any person would take food and would not be able to excrete it, great pains and death would follow in a short time, and yet I am to believe that man has lived for months without that function! Suppose by accident a hole were formed in the belly of a person, it would prove fatal, and yet we are to believe that the navel of the foetus has been open! Why should the foetus not open the eyes, spread forth the bands and stretch out the legs, if, as you think, the limbs are all whole and perfect." This mode of reasoning would lead to the conclusion that man cannot come into existence and develop in the manner described.
If philosophers would consider this example well and reflect on it, they would find that it represents exactly the dispute between Aristotle and ourselves. We, the followers of Moses, our Teacher, and of Abraham, our Father, believe that the Universe has been produced and has developed in a certain
