To a lesser degree, a secret ressentiment underlies every way of thinking which attributes creative power to mere negation and criticism. Thus modern philosophy is deeply penetrated by a whole type of thinking which is nourished by ressentiment. I am referring to the view that the true and the given is not that which is self-evident, but rather that which is indubitable or incontestable, which can be maintained against doubt and criticism.
