The revival of interest in rhetoric raises the question of the relevance of the discipline to the modern student, particularly the engineering student. In general, rhetoric can be defined as the study of language emphasizing its practical rather than its aesthetic qualities. As a theory of composition, classical rhetoric stresses writing as communication rather than self-expression, and provides a systematic method for dealing with problems of achieving cooperation among men. As a “systems approach” to composition, rhetoric is suited to the mental style of the engineering student. Moreover, engineers and scientists skilled in rhetoric would be equipped to deal with the problem of alienation between the scientific community and society at large.
