The theory of concepts advanced in the present discussion aims at accounting for a) how a concept makes successful practice possible, and b) how a scientific concept can be subject to rational change in the course of history. To this end, I suggest that each scientific concept consists of three components of content: 1) the concept’s reference, 2) its inferential role, and 3) the epistemic goal pursued with the concept’s use. In the course of history a concept can change in any of these three components, and change in one component—including change of reference—can be accounted for as being rational relative to other components, in particular a concept’s epistemic goal. This framework is motivated and spelled out based on a concrete case: the history of the homology concept in biology.
