Honoré was a close associate of H. L. A. Hart. They jointly wrote Causation in the Law (Oxford, 1st ed. 1959, 2nd 1985) in 1953-8 and Honoré had some influence on Hart's The Concept of Law (Oxford, 1st ed. 1961, 2nd 1994). A number of his philosophical papers are collected in Making Law Bind (Oxford, 1987) and Responsibility and Fault (Oxford, 1999) and his contributions to legal philosophy and Roman law, which range widely, include 16 books and more than a 100 articles published over six decades.
Honoré was an honorary Q.C. and Bencher of Lincoln's Inn, a member of the British and Bavarian Academies and of the International Academy of Comparative Law. In South Africa, his standing has been recognised by the award of honorary degrees from the Universities of South Africa, Stellenbosch and Cape Town. When receiving this last degree, in 1990, he had the opportunity to give an address. He used this opportunity to point to the parallel between the extension of citizenship to all free people in the Roman Empire, regardless of race, sex or religion, by Caracalla in 211 AD, and the extension of citizenship to the whole of the South African population. This he foresaw would need an adjustment of the legal system, and he suggested a constitutional court to carry it through with a parallel to the composition of the German Constitutional Court. Nelson Mandela approved of this. It was put into practice in 1995, and has been a success.
He delivered the Hamlyn lectures (1982), the Blackstone and H. L. A. Hart lectures, the J. H. Gray lectures at Cambridge and the Maccabaean lecture in Jurisprudence at the British Academy. Three Festschriften have been published in his honour.
