Abstract

The notions ‘conservative’ and ‘progressive’ in social sciences and public opinion have given rise to two distinctive political ideologies. In this issue we deal, starting from Kant, with different historical senses of the notions of conservative and progressive in the social sciences as applied to the present: Buchanan’s constitutional economy, Popper’s open society, Rawl’s theory of justice and Ortega y Gasset’s philosophical conception of social and political life.
