Personally, I think social conservatives have much to learn from Antonio Gramsci. His work on cultural hegemony provides a road map to reverse the slide into social liberalism. Gramsci believed that Marxists must work to seize control of cultural institutions in order for Marxism to succeed. The same goes for social conservatives.
Interesting that you think that. Yes, Gramsci is someone that everyone should take seriously, not just in terms of politics, but when thinking about society (and what it is). He's one of
very few 20th century Marxist thinkers to be praised by Kołakowski in the third volume of
Main Currents of Marxism.
