Recent rhetorical critiques of philosophy and science assume a contrast between rational argument and rhetoric that is inherited from an antirhetorical tradition in philosophy. This article rejects that assumption. Rhetoric is compatible with reasoned discourse in a strong sense originally outlined by Aristotle. Rhetorical analysis reveals the inadequacy of purely demonstrative accounts of rational argument and cognitive accounts of the conditions for rational assent to propo sitions. Social studies of the rhetoric of science, and in particular of credibility claims, need (...) not fall into the forms of relativism and global antirealism with which they have become associated.

The ArgumentA scientific work presupposes a body of texts that are a condition for its intelligibility. This paper shows that the study of intertextual reference — of the ways a text indicates its relation to other texts — provides a fruitful perspective in the study of science that deserves more attention than it has hitherto received. The paper examines intertextual reference in early nineteenth-century mathematics, first surveying a variety of mathematical texts in the period and then examining in detail W.R. (...) Hamilton's work on quaternions.Three questions are addressed: (1) What forms of intertextual reference are employed? (2) What is the range of intertextual reference? (3) What are the functions of intertextual reference? The answers to the first two questions provide an unexplored perspective on the institutional changes in science during the period. The transitional status of the period in the development of later professional science is reflected in the relative openness in the forms of intertextual reference employed and the range of texts to which reference was made. In virtue of these features the period is particularly fruitful in the study of the functions of intertextual reference. With some major qualifications, the paper defends a Mertonian view that intertextual reference needs to be understood in terms of the claim to intellectual property rights. (shrink)
