Abstract
The 3Rs, or the replacement, reduction, and refinement of animal research, are widely accepted as the best approach to maximizing high-quality science while ensuring the highest standard of ethical consideration is applied in regulating the use of animals in scientific procedures. This contrasts with the muted scientific interest in the 3Rs when they were first proposed in The Principles of Humane Experimental Technique (1959). Indeed, the relative success of the 3Rs has done little to encourage engagement with their original text, which remains little read and out of print. By adopting a historical perspective, this article argues that one explanation for this disjunction may be found in another, more celebrated, event of 1959: C. P. Snow's Rede lecture on The Two Cultures. The moral outlook of The Principles of Humane Experimental Technique derived from an earlier ethos wherein humanistic and scientific values occupied a shared culture. While the synthetic style of The Principles has hindered its readership, this article concludes that there is value to recovering the notion that the humanities and social sciences can contribute to the improvement of animal research.
