Little by little this idea of a definite purpose and use in this and that thing falls back and the child gets interested more in the production or origination of things. He wants to know who made the trees, the birds, the stars and so forth. Here, though what we call efficient, as distinguished from final, cause is recognised, anthropomorphism survives in the idea of a maker analogous to the carpenter. We shall see later that children habitually envisage the deity as a fabricator. All this rage of questioning about the uses and the origin of things is the outcome, not merely of ignorance and curiosity, but of a deeper motive, a sense of perplexity, of mystery or contradiction. It is not always easy to distinguish the two types of question, yet in many cases at least its form and the manner of putting it will tell us that it issues from a puzzled and temporarily baffled brain. As long as the questioning goes on briskly we may infer that a child believes in the possibility of knowledge, and has not sounded the deepest depths of intellectual despair. More pathetic than the saddest of questions is the silencing of questions by the loss of faith. It is easy to see that children must find themselves puzzled with much which they see and hear of. The apparent exceptions to rules don’t trouble the grown-up persons just because as _recurrent_ exceptions they seem to take on a rule of their own. Thus adults though quite unversed in hydrostatics would be incapable of being puzzled by C.’s problem: why my putting my hand in water does not make a hole in it. Similarly, though they know nothing of animal physiology they are never troubled by the mystery of fish breathing under water, which when first noted by a child may come as a sort of shock. The little boy just referred to, in his far-reaching zoological interrogatory asked his mother: “Can they (the fish) breathe with their moufs under water?” In his own investigations, and in getting instruction from others, the child is frequently coming upon puzzles of this sort. The same boy was much exercised about the sea and where it went to. He expressed a wish to take off his shoes and to walk out into the sea so as to see where the ships go to, and was much troubled on learning that the sea got deeper and deeper, and that if he walked out into it he would be drowned. At first he denied the paradox (which he at once saw) of the incoming sea going uphill: “But, mamma, it doesn’t run up, it doesn’t run up, so it couldn’t come up over our heads?” He was told that this was so, and he wisely began to try to accommodate his mind to this startling revelation. C., it will be seen, was much exercised by this problem of the moving mass of waters, wanting to know whether it came half way up the world. Probably in both these cases the idea of water rising had its uncanny alarming aspect.
