This paper contributes to debates regarding the normative justification of basic income (BI) via a critical reevaluation of Philippe Van Parijs’ ‘real-libertarian’ theory. Van Parijs’ work constitutes the most ambitious attempt within the literature to ground a justification of BI within a systematic normative framework. In this paper I argue that key elements of his framework should form part of any progressive justification of BI. Specifically, his linking of the principle of ‘real freedom for all’ with the policy mechanism of (...) the ‘highest sustainable basic income.’ I take issue with Van Parijs’ treatment of compensation for unequal internal endowments based on the criterion of ‘undominated diversity’ and I reject the ‘external resources’ approach to justifying the funding of a substantial BI, including Van Parijs’ ‘jobs as assets’ argument. I introduce the concept of ‘total social productivity’ as a means of understanding the production and reproduction of society in a manner that anchors the justification of BI in a commitment to a ‘deep form of social reciprocity.’ Finally, I suggest that BI be framed as a ‘pragmatic-utopian reform.’.
