I think most conservatives defer to and value tradition and customs because they feel this, even though they may not articulate it in the same way. Roger Scruton gives a nice summary, in his book on conservatism: https://www.amazon.com/Conservatism-Invitation-Tradition-Rog...

Similarly liberals who say things like "all men are created equal and have the same rights and can institute whatever practices seem right to them" may not know anything about Rousseau and blank slates, but they are expressing these views.

Thanks for the Chesterton quote. Chesterton is awesome. A bit of a lunatic, but also insightful and fun to read.
