In this paper I show that in its original setting Boyle's New Experiments was not only rhetorical but also ideological. By employing a Lacanian theory of the subject, I show that this text not only disguised various “real contradictions“ in the fabric of Restoration society but also acted as a site for certain textual practices that played a role in the constitution of a new form of subjectivity for scientists. I also address the philosophical question of whether the ideological and rhetorical nature of scientific texts impugns the status of their theoretical claims as paradigms of knowledge and rational belief.
