Joseph Raz, the master of analytic philosophy of law who died in London last month, argued that law and policy should reflect a vision of the human good, with the good of personal autonomy—enabling people to be “authors of their own lives”—at its heart. He was a true philosopher, a truth-seeker: he had convictions, but he never sought to immunize them against criticism, nor did he allow himself to fall so deeply in love with his opinions that he valued them above truth itself.
