John Finnis (University of Oxford - Faculty of Law) has posted
Equality and Differences (The H.L.A. Hart Memorial Lecture in the University of Oxford, June 2011) on SSRN. Here is the abstract:
This revised and annotated version of the H.L.A. Hart Memorial lecture in the University of Oxford in June 2011 has some significant differences in coverage from the essay of the same title published in the American Journal of Jurisprudence 56 (2011) 17-44, including a brief discussion of Waldron’s treatment of basic equality and Cohen’s 'luck-egalitarianism'. The general theme is that neglect of inequalities and of preconditions for sustainable common good tends to ensure that legal measures promoting equality rights and condemning discrimination yield serious injustices (violations of rights).
Highly recommended.
