How much longer will we leave ethics to philosophical pseudoscience?

ARGUMENTATIVE METHODS

  1. Mythical (Allegorical) (Theological)
  2. Psychological (Moral) (The Anglo Scottish Enlightenment)
  3. Rational (Kantian) (Germanic Libertarians)
  4. Historical (analogical)
  5. Empirical (positivist)
  6. Ratio-empirical ( scientific )
  7. Descriptive (purely descriptive statements free of analogy).

QUESTION:

Which philosophers who advocate liberty rely on which argumentative methods?

(I can tell you that I rely upon ratio-empirical arguments.)
