In children two and three years of age we find all these elements of reasoning present and functioning. The product of children’s reasoning is often irrational, but the processes are all there. The following instances from a collection of children’s sayings by Mr. H. W. Brown show children making inductions and deductions after the same general fashion as adults:— (2 yrs.) T. pulled the hairs on his father’s wrist. Father. “Don’t, T., you hurt papa!” T. “It didn’t hurt grandpa.” (2 yrs. 5 mos.) M. said, “Gracie can’t walk, she wears little bits of shoes; if she had mine, she could walk. When I get some new ones, I’m going to give her these, so she can walk.” (2 yrs. 9 mos.) He usually has a nap in the forenoon, but Friday he did not seem sleepy, so his mother did not put him to bed. Before long he began to say, “Bolly’s sleepy; mamma put him in the crib!” This he said very pleasantly at first; but, as she paid no attention to him, he said, “Bolly cry, then mamma will.” And he sat down on the floor and roared. (3 yrs.) It was between five and six in the afternoon; the mother was getting the baby asleep. J. had no one to play with. He kept saying, “I wish R. would come home; mamma, put baby to bed, so R. will come home.” I usually get home about six, and as the baby is put to bed about half-past five, he had associated the one with the other. (3 yrs.) W. likes to play with oil paints. Two days ago my father told W. he must not touch the paints any more, for he was too small. This morning W. said, “When my papa is a very old man, and when I am a big man and don’t need any papa, then I can paint, can’t I, mamma?” (3 yrs.) G.’s aunt gave him ten cents. G. went out, but soon came back saying, “Mamma, we will be rich now.” “Why so, G.?” “Because I planted my ten cents, and we will have lots of ten cents growing.” (3 yrs.) B. climbed up into a large express wagon, and would not get out. I helped him out, and it was not a minute before he was back in the wagon. I said, “B., how are you going to get out of there now?” He replied, “I can stay here till it gets little, and then I can get out my own self.” (3 yrs.) F. is not allowed to go to the table to eat unless she has her face and hands washed and her hair combed. The other day she went to a lady visiting at her house and said, “Please wash my face and hands and comb my hair; I am very hungry.” (3 yrs.) If C. is told not to touch a certain thing, that it will bite him, he always asks if it has a mouth. The other day he was examining a plant, to see if it had a mouth. He was told not to break it, and he said, “Oh, it won’t bite, because I can’t find any mouth.”
