"But among the forces cultivated by morality was truthfulness: this eventually turned against morality, discovered its teleology, its partial perspective— and now the recognition of this inveterate mendaciousness that one despairs of shedding becomes a stimulant. Now we discover in ourselves needs implanted by centuries of moral interpretation— needs that now appear to us as needs for untruth; on the other hand, the value for which we endure life seems to hinge on these needs. This antagonism— not to esteem what we know, and not to be allowed any longer to esteem the lies we should like to tell ourselves— results in a process of dissolution."
