"Dictatorship of relativism"

I am not a Roman Catholic but I like Benedict XVI's comment as follows:
​
Today, a particularly insidious obstacle to the task of education is the massive presence in our society and culture of that relativism which, recognising nothing as definitive, leaves as the ultimate criterion only the self with its desires. And under the semblance of freedom it becomes a prison for each one, for it separates people from one another, locking each person into his or her own ego.[69]

He said that "a dictatorship of relativism"[70] was the core challenge facing the church and humanity. At the root of this problem, he said, is Kant's "self-limitation of reason". This, he said, is contradictory to the modern acclamation of science whose excellence is based on the power of reason to know the truth. He said that this self-amputation of reason leads to pathologies … [71] Benedict traced the failed revolutions and violent ideologies of the 20th century to a conversion of partial points of view into absolute guides. He said "Absolutizing what is not absolute but relative is called totalitarianism."[72]
