Philosophie et science économiques : leur contribution respective aux discours politiques

The paper is the second message (the first was called “Toward another economic science (and thus toward another institution of this science)”) of the author to the French heterodox economists (post-Keynesians, Marxists, regulationists, conventionalists, socio-economists) which has the aim to convince them to adopt the constructivist institutionalist methodology in their research and the philosophies of social constructivism and communitarianism in their social, moral and political philosophical developments. The first part of the paper discusses four faces of economics: science, philosophy, ideology, and utopia. The second part of the paper considers two world views and two versions of economics. In the third part of the paper a project for the economics profession is presented, which I call discursive troika. Economics, as Discursive Troika, is an inquiry, a policy development activity and a social philosophy. All of them must be based on discursive ontology, so economics, as an investigative activity, represents discourse/text analysis, and this is the first element of the discursive troika. The second element of the discursive troika is policy development activity in the framework of discursive or deliberative democracy. The necessary condition of the efficiency of this type of policy development is argumentational integrity of participants, which is linked with the third element of the discursive troika called discourse ethics. Without deliberative democracy there is no demand by the public for non-deviated inquiry and no large-scale supply of research by economists, as they will not be given the opportunity to conduct their research-investigation. Neither discursive inquiry nor deliberative democracy is possible without discourse ethics.
