Rhetoric of Science: The Problem of Status

Abstract

This contribution examines the status of the rhetoric of science in two contexts. The first one is the effect that the changing interpretation of logic (the changing 'image of logic') has had on the status of the rhetoric of science. The second is the role that imagery has in scientific discourse. It is argued that the very possibility of a rhetorical interpretation of science depends on how the logic of science is understood. Informal logic, which acts here as a variant of argumentation theory or a logic of argumentation, is proposed as such a logic. This leads to a revision of the nature of justification in science in general, the substitution of apodictic logic for a logic of argumentation as a principal tool, and the consideration of strict formal ways of material implication-based justification as mere individual cases of a logic of argumentation. The role of imagery in scientific discourse is analysed. It is demonstrated that the situation of rhetoric and perception of imagery is paradoxical: although using rhetorical mechanisms in scientific communication is unavoidable, rhetoric has been criticised for many centuries. It is shown that the negative attitude to using rhetorical elements in scientific texts has long historical roots going back to ancient philosophical thought, namely, Socrates's criticism of eloquence and sophistic rhetoric. Analysis of the functions of imagery in scientific discourse suggests that imagery is an inalienable mechanism of both professional communication and the creation of theoretical models of knowledge.
