Nietzsche's criticisms were directed against what he reckons as the progressive 'moral' disintegration of late 19th century Germany. He described morality as "the doctrine of the relations of supremacy (Herrschafts-Verhaltnissen) under which the phenomenon of 'life' comes to be." This definition, however, is broad and mired in ambiguity, and as will be pointed out later, escapes multitudinous 'moralities' available throughout Nietzsche's corpus which had been culled by scholars, such as Heidegger and Solomon.
