Economists, and particularly economic historians, definitely still take Adam Smith very seriously

That it's particularly true of economic historians is a bad sign that they like him just because he's old, or because his examples match their work.

I was advocating those authors for a somewhat different reason than the post. They are advocating new ideas which are taught today, but which are taught as the status quo. The original authors are more careful to argue for them and more careful to delineate them. I took you more to be talking about reading arguments between two schools that both eventually lost so that one does not have a stake in their arguments.
