Our paper offers a novel reading of Sen's idea of justice, beyond the standard prisms imposed by theories of justice-resting on external normative criteria-and formal welfarism-involving the definition of individual welfare and its aggregation. Instead we take seriously Sen's emphasis on personal agency and focus on his original contribution to the issue of objectivity. Firstly, we demonstrate that Sen's idea of justice, with at its core "positional views", is more respectful of persons' agency than would be a theory based on individual preference or capability. Secondly, we argue that Sen's conception of objectivity considers that both information and sentiments are relative to a position. Such an alternative approach to subjectivity allows the formation of more impartial views through collective deliberation and a better consideration of justice by agents themselves.
