 Empirical accounts of the existing plurality of scientific cultures can be complemented with normative arguments in favor of heterogenous forms of inquiry. Such a normative case for pluralism has been most famously articulated in Feyerabend’s (1975) plea for anarchism in science and finds more recent expressions in what Chang (2012) calls “active normative epistemic pluralism”. This pluralism takes an active normative stance in the sense of advocating for the cultivation of multiple systems of practice in the same field of study to reap benefits of toleration (different practices producing different valuable results) and benefits of interaction (interactions of practices jointly produce valuable results).
