Quotations by:
Moynihan, Daniel Patrick
The central conservative truth is that it is culture, not politics, that determines the success of a society. The central liberal truth is that politics can change a culture and save it from itself.
Daniel Patrick Moynihan (1927-2003) American politician, diplomat, sociologist
Godkin Lecture, Harvard (1985)
