Abstract
One of the most salient lessons from HPS as a discipline is that science is a living, breathing endeavor; one whose rules and values are constantly changing. As such, there is an essential tension between the hope for a coherent, unified conception of scientific rationality on the one hand, and the recognition of the diversity of perspectives which fit into the framework called science. The big question, of which I hope to answer a small part, is: how can rationality and relativism be reconciled with one another? To do this, I present a rational reconstruction of a theory of scientific change which resembles Barseghyan’s theory of scientific change. I interpret scientific knowledge modally; the scientific mosaic of a community at a particular time is taken to represent the actual instantiation of a collection of possible scientific changes, all linked to one another through a Kripkean semantics of possible worlds. I then draw a correspondence between accepted scientific theories and employed methods with logical axioms and rules of inference respectively and use this to construct a logical framework for studying the modality of scientific knowledge. I use this framework to obtain a notion of scientific rationality which is contextually localized, but still presents a clear direction of scientific development at every individual time step.
