A Sentimentalist Moral Psychology
This chapter attributes to Nietzsche a sentimentalist moral psychology, according to which our normative judgements and motivational responses are ineradicably shaped and constrained by our antecedent motives. This can be contrasted to rationalist views, which accept a purity thesis. After precisfying the sentimentalist view, the chapter suggests that standard philosophical arguments both for and against it are inconclusive. To make headway, it then turns to empirical evidence. Even if empirical evidence could never definitively rule rationalism out, there is a wealth of evidence strongly supporting sentimentalism. This completes the case against those defences of categoricity like Kant’s resting on a purity thesis; sentimentalism will also be important for the model of normativity developed later.
