The search for alternatives in education must therefore start with an agreement on what it is we mean by "school." This might be done in several ways. We could begin by listing the latent functions performed by modern school systems, such as custodial care, selection, indoctrination, and learning. We could make a client analysis and verify which of these latent functions render a service or a disservice to teachers, employers, children, parents, or the professions. We could survey the history of Western culture and the information gathered by anthropology in order to find institutions which played a role like that now performed by schooling. We could, finally, recall the many normative statements which have been made since the time of Comenius, or even since Quintilian, and discover which of these the modern school system most closely approaches. But any of these approaches would oblige us to start with certain assumptions about a relationship between school and education. To develop a language in which we can speak about school without such constant recourse to education, I have chosen to begin with something that might be called a phenomenology of public school. For this purpose I shall define "school" as the age-specific, teacher-related process requiring full-time attendance at an obligatory curriculum.
