For what should we be thankful?
We enjoy remarkable prosperity and liberty. We possess economic opportunity, personal freedom, and physical safety to an extent unrivaled in human history. We advance steadily against social injustice.
We have this life in large part because of the ideas and institutions that we received from our Founding Fathers. We have it as well because of the institutions and values that we share as members of Western civilization.
We too seldom discuss the latter.
