In this interview Laura Valentini, lecturer in political philosophy at University College London (UCL), talks to Global Policy's Suzanna Sobolewska about issues surrounding global justice in the 21st Century. The interview tackles challenging questions including defining and achieving justice, and how democracy and justice are interlinked. Dr. Valentini interprets justice as the organisation of the distinct spheres of freedom that each individual is entitled to, as well as the restrictions on the exercise of legitimate coercion. In reference to her recently published book Justice in a Globalized World, Dr. Valentini engaged with the cosmopolitan and statist approaches to justice, outlining their strengths and weaknesses. The interview concludes with suggestions for aspiring academics and practitioners interested in questions of justice.
