This book is for the student in the introductory course on deviant be­ havior and in related courses. A wide range of ideas and facts is set forth in a way that should be comprehensible to the student without prior knowledge of this area of study. In Chapter 1, "The Nature of Deviance, " various ways of defining deviance are explored and one is settled upon: Deviance is behavior that is unusual, not typical, in a society or group. Chapter 2 is devoted to a preliminary consideration of several main currents of social thought that seek to explain why deviance comes about and is perpetrated. These explanations fall into four broad theo­ retical categories. First, there are those theories that view the major sources of deviance as having to do with the extent to which individ­ uals are bound into or dissociated from the group, these are termed social integration theories. Second, there are the cultural support the­ ories, which specify that there are subcultures of deviance, that is, bod­ ies of customs and values that advocate a given form of deviance and are socially transmitted from one person to another through the learn­ ing process. Third, there are social disorganization and conflict theo­ ries, which focus on the ways in which a lack of group organization and the presence of broad social and cultural conflicts bring about de­ viance.
