Abstract

I often run along a path near my home. Recently I noticed something about my behavior: On especially crowded days I seldom greet either walkers or bikers, who are often talking in couples or riding by at high speeds. But when I meet other runners, I almost always say or signal hello. I interpret my greeting practice as a mode of identification: identifying with others sharing a running practice. For certain purposes, runners might identify with walkers and bikers, for example, in a civic action to save the path from the encroachment of housing developers. But within the group of pathway users, I identify primarily with other runners and, in a certain sense, we form a loose community of running practitioners. This is a very, very rough analogy for what happens at local university functions, at national scholarly conferences, and at non-academic events of all kinds, rhetorical contexts where disciplinary identities are established and reinforced for professional and lay audiences. To analyze performances of disciplinary identities in more depth, I'd like to begin heuristically with a three-dimensional model for locating academic fields in relation to each other. Axis A (Disciplinary Matrices) consists of practices, theories, and traditions; Axis B (Field Boundaries) includes disciplines, interdisciplines, transdisciplines, and non-disciplines; and Axis C (Cultural Sites) comprises ideational domains, material institutions, and public spheres.' Academic disciplines and their subfields can be identified and compared across the different axes of this model. For example, the disciplinary matrix of English Studies includes interpretive practices for critically reading, researching, and teaching texts; aesthetic and other theories for defining textual objects of study; and evolving traditions of texts to be described, compared, and evaluated (canons of literary, critical, and theoretical works). In the twentieth century, English as this matrix of practices, theories, and traditions (Axis A) was identified as a separate discipline (Axis B) with its own ideational domain in relation to other disciplines and its own subfields, institutionalized as an academic department within the
