These children, perhaps truly feral but most likely not, remind us that it is we human beings who ask the questions of one another. The nature of these questions reveals much about the ways in which our own minds work. If we think of the mind as composed of both innate and acquired aspects, we ask one kind of question. If we think of the mind as primarily electrical, we ask questions based on the way electricity flows; if we think of the mind as computerlike, our questions reflect the activities of microchips.
Psychology likewise finds its questions in the models it uses. In this section, I suggest consideration of the four psychologies that are prominent in our century. These are the ideas of measuring mental ability, psychoanalysis, behaviorism, and phenomenology. Each is illustrated by a reaction of events that gave each model prominence.
