Metaphor and the discourse of virology: HIV as human being

Most analysis of the metaphors of AIDS has considered lay rather than scientific discourse. In general, that analysis has uncovered linguistic strategies that tend to distance the disease from people who are healthy. Moreover, it has criticized those strategies insofar as they categorize and dehumanize the AIDS patient. My own analysis, however, focuses on the writing of Robert Gallo, one of the virologists who claimed credit for isolating the HIV as the cause of AIDS. By examining Gallo's popular and scientific writing, I uncover the metaphor system that underlies his work — and perhaps the work of other virologists studying the HIV. I find in Gallo's writing a system of metaphor that personifies and humanizes the HIV (or the HTLV-III as he originally named it). This system differs significantly from lay systems that tend to objectify AIDS. I argue that the metaphor system that underlies Gallo's work is in fact productive, but that it might preclude other ways of conceptualizing the disease and its causes. The co-factor theory, for instance, entails a different metaphoric system entirely. I suggest that AIDS researchers might examine their own language in an effort to critique the metaphors they use and explore the possibility of using new metaphors.
