Funny, I would have said the opposite. The right wants law and justice, the left wants freedom. But it all depends on the definition of those terms, which makes it hard to even talk about. I think a better distinction is that the left is visionary/utopian while the right is stagnant/realistic. Utopianism tests new ideas, but the thesis always collapses as reality modulates it. Leftism is unstable and dangerous if it fails to learn from history, but the progressive impulse is really a valuable thing. Maybe China has it right; they are extremely authoritarian and stable in the mainland, but use Hong Kong as a playground for economic innovation, that they can then import as it proves itself.
