Title: The discourses of science
First published: 1994
Description: In this greatly anticipated revision and translation of Scienza e Retorica, Marcello Pera argues that rhetoric is central to the making of scientific knowledge.

Pera begins with an attack on what he calls the "Cartesian syndrome," the fixation on method shared by supporters of both the "standard" and "new" philosophies of science. He argues that in linking scientific rationality to methodological rules, both sides get it wrong. Scientific knowledge is neither the mirror of nature provided by a universal method, nor a cultural construct imposed by subjective interests.

Pera proposes to overcome the tension between normative and descriptive philosophies of science by focusing on rhetoric in the construction and acceptance of theories. Examining the uses of argumentation in Galileo's Dialogue, Darwin's Origin, and the big bang-steady state controversy in cosmology, Pera shows that scientific research is not just an interchange between nature and the observer.

Rather, science is a three-way interaction among nature, the investigator, and a questioning community which, through the process of attack, defense, and dispute, determines what science is. Rhetoric, then, understood as the practice of scientific argumentation, is an essential element in the constitution of science.

. As a powerful alternative to dominant philosophies of science and a bold reconsideration of rhetoric and dialectic more broadly, this book addresses contemporary questions in philosophy, rhetoric, history of science, literary criticism, and cognitive science.
