Re: Substitutes.
"Snowden, like a number people on this forum, seems to think that sanctimonious bourgeois platitudes and verities are acceptable substitutes for political, historical, and societal insight."
Verity:
Noun
A true principle or belief, esp. one of fundamental importance.
I go along with a true principle or belief, esp. one of fundamental importance, being more important than "political insight".
As for "historical, and societal insight", I take it yours doesn't include such matters as the abolition of slavery, not sending children up chimneys, votes for women, etc., since reforms such as these arose from verities taking precedence.
(No comment on "sanctimonious bourgeois platitudes", as the words in that context constitute little more than a sanctimonious, bourgeois platitude).
