Abstract

In this article I argue that Karl Popper embraced a muitiplist approach to ethics, politics, history, and cultural practices. Although Popper combined metaphysical realism with a hermeneutic approach that had the potential to support a multiplist philosophy of science, a commitment to verisimilitude and to the identification of universal laws required him to adopt a singularist approach to natural science. I suggest, therefore, that Michael Krausz’ description of Popper as a singularist should be qualified’ that Popper’s philosophy of natural science may be identified with singularism but that recognition should be afforded to his multiplist approach to other fields.
