This article uses the sociological concept of to explain several aspects of writing instruction. In sociological theory, underlife refers to those behaviors which undercut the roles expected of participants in a situation-the ways an employee, for example, shows she is not just an employee, but has a more complex personality outside that role. In contemporary writing instruction, both students and teachers undercut the traditional roles of the American educational system in order to substitute more complex identities in their place.

Both sets of behaviors are behaviors, for they seek to provide identities that go beyond the roles offered by the normal teacher-as-lecturer, student-as-passive-learner educational system. These forms of underlife, moreover, are connected to the nature of writing itself. Writing, in the rich sense of interactive knowledge creation advocated by theorists like Ann Berthoff in The Making of Meaning and Janet Emig in Web of Meaning, necessarily involves standing outside the roles and beliefs offered by a social situation-it involves questioning them, searching for new connections, building ideas that may be in conflict with accepted ways of thinking and acting. Writing involves being able to challenge one's assigned roles long enough that one can think originally; it involves living in conflict with accepted (expected) thought and action. This article will explore student and teacher behavior in writing instruction as the of the current educational system, and will suggest that the identities which may be developing for students in writing classrooms are
