Noun
transvaluation (plural transvaluations)
A change of values; a revaluation.
What was right and true yesterday is wrong and false today. What was immoral and shameful - promiscuity, abortion, euthanasia, suicide - has become progressive and praiseworthy. Nietzsche called it the transvaluation of all values; the old virtues become sins, and the old sins become virtues. Pat Buchanan
