I think a lot of people went along with the Enlightenment from motives of good. There is some support for the types of governments that sprouted up as a result of Enlightenment principles. While it is becoming more obvious that those principles do not work well, that is no reason to assume everyone that went along with them were bad hearted.

The progress made in the USA and Europe when Enlightenment kinds of laws and constitutions were adopted does not seem trivial.

Socialism mainly uses Hegel for support. Other approaches use John Locke, Hobbes, Kant, Goethe, Hume, Berkeley etc and etc.. That is all the thinkers. Not some. That is to say Throne and Altar approach might be  best but it had the weight of the thinkers and the weight of the evidence against it.
 But I am not sure of what would be better than the Constitution of the USA. It seems to me if not for blacks it would work perfectly well.
