"Legal positivism has become one of the main forces which have destroyed classical liberalism because the latter presupposes a conception of justice which is independent of the expediency for achieving particular results. Legal positivism, like the other forms of constructivist pragmatism of a William James or John Dewey or Vilfredo Pareto, is therefore profoundly antiliberal in the original meaning of the word, though their views have become the foundations of that pseudo-liberalism which in the course of the last generation has arrogated the name."
