Abstract
For too long, journal articles and textbooks on scientific and technical discourse have adopted a positivistic approach to visuals. Unfortunately, this approach is problematic. It ignores that visuals are constructions that are products of a writer's interpretation with its own power-laden agenda. For example, in representing a tamed and dominated nature, visuals become instruments of patriarchy. Reading them responsibly requires that we uncover some of the values attached to the strategies of creating visuals and to the objects created. This article reviews the current approach taken by composition scholars, surveys richer interdisciplinary work on visuals, and—by using visuals connected with the Human Genome Project—models an analysis of visuals as rhetoric.
