As I mentioned in my post, another definition would be Sowell's, i.e. the different approach each has to human nature. The left views it as infinitely malleable, while the right recognizes man's fallibility and the inability to fundamentally alter something ordained by God/created through evolution.
Then too bad for him as ‘modern’ liberalism is solely a justification for Bread and Circus as exemplified by our government subsidized consumer spending, which is done for the benefit of the media that monopolizes control of the ‘public square’.
Liberalism/conservatism is, and will always be, defined by support for “wise” (democratic0 feudalism/ support for divided governance.
A modern philosopher should heed the effect the medium has on the message and consider the ramification of a consolidated national mass media. Ignoring the distortions caused by the surfaces of Plato’s cave (so to speak) yields sterility.
