John Mitchell Finnis (born 28 July 1940) is an Australian legal scholar and philosopher specialising in the philosophy of law. He is professor of law at University College, Oxford and at the University of Notre Dame, teaching jurisprudence, political theory, and constitutional law. He is admitted to the English Bar as a member of Gray's Inn. He was appointed an honorary Queen's Counsel in 2017.
Finnis was educated at St. Peter's College, Adelaide and the University of Adelaide, where he was a member of St. Mark's College. He obtained his LL.B. there, winning a Rhodes scholarship to University College, Oxford, in 1962, where he obtained his D.Phil. for a thesis on the concept of judicial power, with reference to Australian federal constitutional law.
Finnis was a friend of Aung San Suu Kyi, also an Oxford graduate; and, in 1989, Finnis nominated her for the Nobel Peace Prize. Aung San Suu Kyi won the prize but did not receive it until June 2012, when she recalled how her late husband, Michael Aris, had visited her under house arrest and brought her the news "that a friend, John Finnis" had nominated her for the prize.
Finnis is a legal philosopher and author of Natural Law and Natural Rights (1980, 2011), a seminal contribution to the philosophy of law and a restatement of natural law doctrine. For Finnis there are seven basic goods; life, knowledge, play, aesthetic experience, sociability of friendship, practical reasonableness and religion. Life for Finnis involves all aspects of vitality that enable a person to gain strong willpower. The second aspect of well-being is knowledge and is described as the pure desire to know, simply out of curiosity, as well as a concerning interest and desire for truth. The third aspect, play, is regarded as self-evident as there is no real point of performing such activities, only for pure enjoyment. Aesthetic experience is the fourth aspect and is considered similarly to play however; it does not essentially need an action to occur. The fifth aspect for Finnis is sociability where it is realised through the creation of friendships, that these relationships are fundamental goods. Practical reasonableness is the sixth basic good where it is one’s ability to use their intellect in deciding choices that ultimately shape one’s nature. The final basic good is religion; it encompasses the acknowledgment of a concern for a simplified distinct form of order, where an individual’s sense of responsibility is addressed; it is "all those beliefs that can be called matters of ultimate concern; questions about the point of human existence".
