First, liberals begin with subjectivity, while conservatives begin with objectivity.
Liberals prioritize personal freedom; conservatives prioritize objective truth. Liberals absolutize persons and see truth as relative to persons. Conservatives absolutize truth and see persons as relative to truth. (Both are right in what they affirm and wrong in what they deny. Both persons and truth are absolute.)
Second, in their anthropology, liberals prioritize the heart, while conservatives prioritize the mind. An attempted mutual heart and brain transplant between a conservative and a liberal failed because no one could find a conservative who would give up his heart to a liberal or a liberal who had any brains to give to a conservative.
Third, liberals emphasize the abstract universal, the cosmopolitan, the global, while conservatives emphasize the concrete particular: individuals, families, neighborhoods and nations. (Thus, the “bad liberalism” of “leftist” communism is international socialism, while the “bad conservatism” of “rightist” Nazism is national socialism.)
Fourth, most obviously, liberals love change and conservatives love permanence; liberals love the new, conservatives the old. That is a matter of temperament rather than ideological content, for anti-Establishment liberals turn into Establishment conservatives when they succeed. And truth is not told by clocks any more than time is told by syllogisms.He's right, you know.
