Abstract
What is the relation between the concept good and more specific or ‘thick’ concepts such as admirable or courageous? I argue that good or more precisely good pro tanto is a general concept, but that the relation between good pro tanto and the more specific concepts is not that of a genus to its species. The relation of an important class of specific evaluative concepts, which I call ‘affective concepts’, to good pro tanto is better understood as one between a determinable and its determinates, whereas concepts such as courageous can be analysed in terms of affective concepts and purely descriptive concepts.
