83-560: Brian Leiter ( / ˈ l aɪ t ər / ; born 1963) is an American philosopher and legal scholar who is Karl N. Llewellyn Professor of Jurisprudence at the University of Chicago Law School and founder and Director of Chicago's Center for Law, Philosophy & Human Values. A review in Notre Dame Philosophical Reviews described Leiter as "one of the most influential legal philosophers of our time", while
166-409: A Wheaton College philosopher. Both Schafersman and Strahler assert that it is illogical to try to decouple the two senses of naturalism. "While science as a process only requires methodological naturalism, the practice or adoption of methodological naturalism entails a logical and moral belief in philosophical naturalism, so they are not logically decoupled." This “[philosophical] naturalistic view
249-492: A continuum . "Naturalism is not so much a special system as a point of view or tendency common to a number of philosophical and religious systems; not so much a well-defined set of positive and negative doctrines as an attitude or spirit pervading and influencing many doctrines. As the name implies, this tendency consists essentially in looking upon nature as the one original and fundamental source of all that exists, and in attempting to explain everything in terms of nature. Either
332-597: A "derogatory and intimidating" e-mail sent by Leiter to one of their colleagues. A majority of the Advisory Board of the PGR (30 of the 54 members) thought it best that he relinquish control over the Report's management. In response, Leiter appointed a co-editor for the 2014 report Berit Brogaard , a philosophy professor at the University of Miami , and agreed to step down as editor after its publication. Leiter dismissed
415-458: A contrast to "naturalism" in general, but there the idea was not really developed to its more recent distinctions. According to Steven Schafersman , naturalism is a philosophy that maintains that; Or, as Carl Sagan succinctly put it: " The Cosmos is all that is or ever was or ever will be ." In addition Arthur C. Danto states that naturalism, in recent usage, is a species of philosophical monism according to which whatever exists or happens
498-424: A difficult predicament." W. V. O. Quine describes naturalism as the position that there is no higher tribunal for truth than natural science itself. In his view, there is no better method than the scientific method for judging the claims of science, and there is neither any need nor any place for a "first philosophy", such as (abstract) metaphysics or epistemology , that could stand behind and justify science or
581-507: A distinct personal anthropomorphic god – theists challenge the idea that nature contains all of reality. According to some theists, natural laws may be viewed as secondary causes of God(s). In the 20th century, Willard Van Orman Quine , George Santayana , and other philosophers argued that the success of naturalism in science meant that scientific methods should also be used in philosophy. According to this view, science and philosophy are not always distinct from one another, but instead form
664-540: A divine Artisan , contrasts sharply with the various mechanistic Weltanschauungen , of which atomism was, by the fourth century at least, the most prominent ... This debate was to persist throughout the ancient world. Atomistic mechanism got a shot in the arm from Epicurus ... while the Stoics adopted a divine teleology ... The choice seems simple: either show how a structured, regular world could arise out of undirected processes, or inject intelligence into
747-523: A law professor and was also a UCC drafter. She also accepted a teaching post at Chicago and later became dean of University of Miami School of Law . Llewellyn died in Chicago of a heart attack on February 13, 1962. Compared with traditional jurisprudence , known as legal formalism , Llewellyn and the legal realists proposed that the facts and outcomes of specific cases composed the law, rather than logical reasoning from legal rules. They argued that law
830-495: A major theme in many of these contexts. In legal philosophy, Leiter has offered a reinterpretation of American Legal Realism as embodying a prescient philosophical naturalism and a defense of what he called "naturalized jurisprudence" in his book Naturalizing Jurisprudence: Essays on American Legal Realism and Naturalism in Legal Philosophy (Oxford University Press, 2007). Upon publication, Jeremy Horder wrote that
913-500: A methodology based on falsifiability for demarcation , because no number of experiments can ever prove a theory, but a single experiment can contradict one. Popper holds that scientific theories are characterized by falsifiability. Alvin Plantinga , Professor Emeritus of Philosophy at Notre Dame , and a Christian , has become a well-known critic of naturalism. He suggests, in his evolutionary argument against naturalism , that

#1732798808272996-554: A naturalistic framework. An example of a more progressive naturalistic philosophy is secular humanism . The current usage of the term naturalism "derives from debates in America in the first half of the last century. Currently, metaphysical naturalism is more widely embraced than in previous centuries, especially but not exclusively in the natural sciences and the Anglo-American, analytic philosophical communities. While
1079-436: A paradigm – comprise a collection of beliefs, values and techniques that are held by a given scientific community, which legitimize their systems and set the limitations to their investigation. For naturalists, nature is the only reality, the "correct" paradigm, and there is no such thing as supernatural , i.e. anything above, beyond, or outside of nature. The scientific method is to be used to investigate all reality, including
1162-432: A particularly strong form of ontological naturalism, namely the physicalist doctrine that any state that has physical effects must itself be physical. From the 1950s onwards, philosophers began to formulate arguments for ontological physicalism. Some of these arguments appealed explicitly to the causal closure of the physical realm (Feigl 1958, Oppenheim and Putnam 1958). In other cases, the reliance on causal closure lay below
1245-550: A passionate suffragette and prohibitionist of Congregationalist conviction. He attended Boys High School . At the age of sixteen he was sent to study in Germany, at the Realgymnasium of Schwerin , where he spent three years and passed his Abitur (school-leaving examination) in the spring of 1911; he learned to speak an excellent German and was able later in life to publish in that language. After having attended
1328-711: A review in The Journal of Nietzsche Studies described Leiter's book Nietzsche on Morality (2002) as "arguably the most important book on Nietzsche's philosophy in the past twenty years." Leiter taught from 1995 to 2008 at the University of Texas School of Law , where he was the founder and director of the Law and Philosophy Program. He joined the University of Chicago faculty in 2008. His scholarly writings have been primarily in legal philosophy and Continental philosophy , especially Nietzsche and Marx . He has also been
1411-652: A visiting professor at universities in the United States and Europe, including Yale University and Oxford University . He is founding editor of a book series entitled Routledge Philosophers , and (with Leslie Green ) of Oxford Studies in Philosophy of Law. Leiter was also the founder and for 25 years the editor of the Philosophical Gourmet Report ("PGR"), an influential but also controversial ranking of philosophy PhD programs in
1494-447: Is natural in the sense of being susceptible to explanation through methods which, although paradigmatically exemplified in the natural sciences, are continuous from domain to domain of objects and events. Hence, naturalism is polemically defined as repudiating the view that there exists or could exist any entities which lie, in principle, beyond the scope of scientific explanation. Arthur Newell Strahler states: "The naturalistic view
1577-529: Is a consequence of the build-up of scientific evidence during the twentieth century for the " causal closure of the physical", the doctrine that all physical effects can be accounted for by physical causes. By the middle of the twentieth century, the acceptance of the causal closure of the physical realm led to even stronger naturalist views. The causal closure thesis implies that any mental and biological causes must themselves be physically constituted, if they are to produce physical effects. It thus gives rise to
1660-712: Is co-editor with Michael E. Rosen of The Oxford Handbook of Continental Philosophy . He has written a considerable amount on the philosophical work of Friedrich Nietzsche , including an article for the Stanford Encyclopedia of Philosophy . In particular, Leiter defended a reading of Nietzsche as a philosophical naturalist in his Nietzsche on Morality (London: Routledge, 2002) and in later papers, including one with Joshua Knobe on "The Case for Nietzschean Moral Psychology" in Nietzsche and Morality (Oxford University Press, 2007). In 2014, when student members of
1743-432: Is commonly referred to as metaphysical naturalism . On the other hand, the more moderate view that naturalism should be assumed in one's working methods as the current paradigm, without any further consideration of whether naturalism is true in the robust metaphysical sense, is called methodological naturalism . With the exception of pantheists – who believe that nature is identical with divinity while not recognizing

"Scientists can defuse some of the opposition to evolution by first recognizing that the vast majority of Americans are believers, and that most Americans want to retain their faith." Scott apparently believes that "individuals can retain religious beliefs and still accept evolution through methodological naturalism. Scientists should therefore avoid mentioning metaphysical naturalism and use methodological naturalism instead." "Even someone who may disagree with my logic … often understands
1909-488: Is most notably a Western phenomenon, but an equivalent idea has long existed in the East . Naturalism was the foundation of two out of six orthodox schools and one heterodox school of Hinduism. Samkhya , one of the oldest schools of Indian philosophy puts nature ( Prakriti ) as the primary cause of the universe, without assuming the existence of a personal God or Ishvara . The Carvaka, Nyaya, Vaisheshika schools originated in
1992-560: Is much more recent, though. According to Ronald Numbers , it was coined in 1983 by Paul de Vries, a Wheaton College philosopher. De Vries distinguished between what he called "methodological naturalism", a disciplinary method that says nothing about God's existence, and "metaphysical naturalism", which "denies the existence of a transcendent God". The term "methodological naturalism" had been used in 1937 by Edgar S. Brightman in an article in The Philosophical Review as
2075-495: Is not a deductive science. Llewellyn epitomized the realist view when he wrote that what judges , lawyers , and law enforcement officers "do about disputes is, to my mind, the law itself" ( Bramble Bush , p. 3). As one of the founders of the U.S. legal realism movement, he believed that the law is little more than putty in the hands of a judge who is able to shape the outcome of a case based on personal biases. Philosophical naturalism In philosophy , naturalism
2158-403: Is that the particular universe we observe came into existence and has operated through all time and in all its parts without the impetus or guidance of any supernatural agency." "The great majority of contemporary philosophers urge that that reality is exhausted by nature, containing nothing 'supernatural', and that the scientific method should be used to investigate all areas of reality, including
2241-480: Is the best way to explore the processes of the universe and that those processes are what modern science is striving to understand. Karl Popper equated naturalism with inductive theory of science. He rejected it based on his general critique of induction (see problem of induction ), yet acknowledged its utility as means for inventing conjectures. A naturalistic methodology (sometimes called an "inductive theory of science") has its value, no doubt. ... I reject
2324-471: Is the idea that only natural laws and forces (as opposed to supernatural ones) operate in the universe . In its primary sense, it is also known as ontological naturalism , metaphysical naturalism , pure naturalism , philosophical naturalism and antisupernaturalism . "Ontological" refers to ontology , the philosophical study of what exists. Philosophers often treat naturalism as equivalent to materialism , but there are important distinctions between

He is known for his "combative tactics on his blogs and social media." Leiter has spoken in support of academic freedom. He defended Steven Salaita , both online and on television, and Rebecca Tuvel, the philosopher criticized during
2490-603: The Hypatia transracialism controversy . He also wrote in The New York Times in defense of John Yoo against calls for Berkeley to investigate him, concluding, "John Yoo has earned international moral opprobrium for his views.

Leiter taught for two years at the University of San Diego School of Law , and was a visiting assistant professor of philosophy at the University of California, San Diego , before joining the faculty at the University of Texas School of Law in 1995, where he taught until 2008. At Texas, Leiter was the founder and Director of
2905-576: The "book will confirm Brian Leiter's place in the front rank of legal theorists in the world today." Leiter also wrote the entry on "Naturalism in Legal Philosophy" for the Stanford Encyclopedia of Philosophy . On his view, "philosophers generally should aim to unpack the 'concepts that have been vindicated by their role in successful explanation and prediction of empirical phenomena'" and thus should "'take seriously the…social scientific literature on law…to see what concept of law figures in
2988-508: The 'human spirit'." Philosophers widely regard naturalism as a "positive" term, and "few active philosophers nowadays are happy to announce themselves as 'non-naturalists'". "Philosophers concerned with religion tend to be less enthusiastic about 'naturalism'" and that despite an "inevitable" divergence due to its popularity, if more narrowly construed, (to the chagrin of John McDowell , David Chalmers and Jennifer Hornsby , for example), those not so disqualified remain nonetheless content "to set
3071-431: The 17th and 18th centuries. In this period, some metaphysical naturalists adhered to a distinct doctrine, materialism , which became the dominant category of metaphysical naturalism widely defended until the end of the 19th century. Thomas Hobbes was a proponent of naturalism in ethics who acknowledged normative truths and properties. Immanuel Kant rejected ( reductionist ) materialist positions in metaphysics, but he

Similarly, though unnamed and never articulated into a coherent system, one tradition within Confucian philosophy embraced a form of Naturalism dating to the Wang Chong in the 1st century, if not earlier, but it arose independently and had little influence on the development of modern naturalist philosophy or on Eastern or Western culture. Western metaphysical naturalism originated in ancient Greek philosophy . The earliest pre-Socratic philosophers , especially

3569-610: The bar for 'naturalism' higher." Alvin Plantinga stated that Naturalism is presumed to not be a religion. However, in one very important respect it resembles religion by performing the cognitive function of a religion. There is a set of deep human questions to which a religion typically provides an answer. In like manner naturalism gives a set of answers to these questions". According to Robert Priddy, all scientific study inescapably builds on at least some essential assumptions that cannot be tested by scientific processes; that is, that scientists must start with some assumptions as to

Pennock further states that as supernatural agents and powers "are above and beyond

The political philosopher John Gray wrote, "A model of clarity and rigour and at points strikingly original, this is a book that anyone who thinks seriously about religion, ethics, and politics will benefit from reading." Christopher L. Eisgruber , the President of Princeton University , said. "Every reader will learn something from this remarkable book, and, beginning now, every serious scholar of religious toleration will have to contend with Leiter's bold claims." By contrast,

I see no similar problems with the conjunction of theism and the idea that human beings have evolved in

They agree that allowing "science to appeal to untestable supernatural powers to explain how nature functions would make the scientist's task meaningless, undermine the discipline that allows science to make progress, and would be as profoundly unsatisfying as the ancient Greek playwright's reliance upon the deus ex machina to extract his hero from

4399-419: The limits of nature are also the limits of existing reality, or at least the first cause, if its existence is found necessary , has nothing to do with the working of natural agencies. All events, therefore, find their adequate explanation within nature itself. But, as the terms nature and natural are themselves used in more than one sense, the term naturalism is also far from having one fixed meaning". Naturalism

This methodological view, however, raises questions about why the legal philosopher should study only judicial behavior and not something else.

4731-434: The naturalistic view: It is uncritical. Its upholders fail to notice that whenever they believe to have discovered a fact, they have only proposed a convention. Hence the convention is liable to turn into a dogma. This criticism of the naturalistic view applies not only to its criterion of meaning, but also to its idea of science, and consequently to its idea of empirical method. Popper instead proposed that science should adopt

Therefore, philosophy should feel free to make use of the findings of scientists in its own pursuit, while also feeling free to offer criticism when those claims are ungrounded, confused, or inconsistent.

Scott’s approach has found success as illustrated in Ecklund’s study where some religious scientists reported that their religious beliefs affect the way they think about the implications – often moral – of their work, but not the way they practice science within methodological naturalism. Papineau notes that "Philosophers concerned with religion tend to be less enthusiastic about metaphysical naturalism and that those not so disqualified remain content "to set

In contemporary continental philosophy , Quentin Meillassoux proposed speculative materialism , a post-Kantian return to David Hume which can strengthen classical materialist ideas. This speculative approach to philosophical naturalism has been further developed by other contemporary thinkers including Ray Brassier and Drew M. Dalton . The term "methodological naturalism"

These assumptions would then be justified partly by their adherence to the types of occurrence of which we are directly conscious, and partly by their success in representing the observed facts with a certain generality, devoid of ad hoc suppositions."
