Liberal naturalism is a heterodox form of philosophical naturalism that lies in the conceptual space between scientific (or reductive) naturalism and supernaturalism. It allows that one can respect the explanations and results of the successful sciences without supposing that the sciences are the only resource for understanding humanity and dealings with the world and each other.
The term "liberal naturalism" was introduced in 2004 by Mario De Caro & David Macarthur [1] and, independently, by Gregg Rosenberg. [2] This form of naturalism has been ascribed to Immanuel Kant. [3] In De Caro's work, liberal naturalism is developed as a mild metaphysical realism; whereas in Macarthur's work liberal naturalism is associated with metaphysical quietism and opens into a philosophy of the manifest image.
For a liberal naturalist, many things in our everyday world that are not explicable (or not fully explicable) by science are, nonetheless, presupposed by science—e.g., tables, persons, artworks, institutions, rational norms and values. Explaining such things might require non-scientific, non-supernatural resources according to this form of naturalism. So, rather than tailoring their ontology to the posits of the successful sciences, as scientific naturalists do, liberal naturalists recognise the prima facie irreducible reality of everyday objects that are part of what Wilfrid Sellars called "the manifest image".

Liberal naturalism is a "liberal" [5] or "catholic" [6] naturalism for several reasons each of which contrasts with scientific naturalist orthodoxy:
Materialism is a form of philosophical monism which holds that matter is the fundamental substance in nature, and that all things, including mental states and consciousness, are results of material interactions of material things. According to philosophical materialism, mind and consciousness are caused by physical processes, such as the neurochemistry of the human brain and nervous system, without which they cannot exist. Materialism directly contrasts with monistic idealism, according to which consciousness is the fundamental substance of nature.
Willard Van Orman Quine was an American philosopher and logician in the analytic tradition, recognized as "one of the most influential philosophers of the twentieth century". He served as the Edgar Pierce Chair of Philosophy at Harvard University from 1956 to 1978.
Hilary Whitehall Putnam was an American philosopher, mathematician, computer scientist, and figure in analytic philosophy in the second half of the 20th century. He contributed to the studies of philosophy of mind, philosophy of language, philosophy of mathematics, and philosophy of science. Outside philosophy, Putnam contributed to mathematics and computer science. Together with Martin Davis he developed the Davis–Putnam algorithm for the Boolean satisfiability problem and he helped demonstrate the unsolvability of Hilbert's tenth problem.
Pragmatism is a philosophical tradition that views language and thought as tools for prediction, problem solving, and action, rather than describing, representing, or mirroring reality. Pragmatists contend that most philosophical topics—such as the nature of knowledge, language, concepts, meaning, belief, and science—are best viewed in terms of their practical uses and successes.
Christine Marion Korsgaard, is an American philosopher who is the Arthur Kingsley Porter Professor of Philosophy Emerita at Harvard University. Her main scholarly interests are in moral philosophy and its history; the relation of issues in moral philosophy to issues in metaphysics, the philosophy of mind, and the theory of personal identity; the theory of personal relationships; and in normativity in general.
John Henry McDowell is a South African philosopher, formerly a fellow of University College, Oxford, and now university professor at the University of Pittsburgh. Although he has written on metaphysics, epistemology, ancient philosophy, nature, and meta-ethics, McDowell's most influential work has been in the philosophy of mind and philosophy of language. McDowell was one of three recipients of the 2010 Andrew W. Mellon Foundation's Distinguished Achievement Award, and is a Fellow of both the American Academy of Arts & Sciences and the British Academy.
Wilfrid Stalker Sellars was an American philosopher and prominent developer of critical realism, who "revolutionized both the content and the method of philosophy in the United States".
The existence of God is a subject of debate in the philosophy of religion and theology. A wide variety of arguments for and against the existence of God can be categorized as logical, empirical, metaphysical, subjective or scientific. In philosophical terms, the question of the existence of God involves the disciplines of epistemology and ontology and the theory of value.
In metaphysics, conceptualism is a theory that explains universality of particulars as conceptualized frameworks situated within the thinking mind. Intermediate between nominalism and realism, the conceptualist view approaches the metaphysical concept of universals from a perspective that denies their presence in particulars outside the mind's perception of them. Conceptualism is anti-realist about abstract objects, just like immanent realism is.
Early modern philosophy The early modern era of philosophy was a progressive movement of Western thought, exploring through theories and discourse such topics as mind and matter, is a period in the history of philosophy that overlaps with the beginning of the period known as modern philosophy. It succeeded the medieval era of philosophy. Early modern philosophy is usually thought to have occurred between the 16th and 18th centuries, though some philosophers and historians may put this period slightly earlier. During this time, influential philosophers included Descartes, Locke, Hume, and Kant, all of whom contributed to the current understanding of philosophy.
Naturalized epistemology is a collection of philosophic views about the theory of knowledge that emphasize the role of natural scientific methods. This shared emphasis on scientific methods of studying knowledge shifts the focus of epistemology away from many traditional philosophical questions, and towards the empirical processes of knowledge acquisition. There are noteworthy distinctions within naturalized epistemology. Replacement naturalism maintains that we should abandon traditional epistemology and replace it with the methodologies of the natural sciences. The general thesis of cooperative naturalism is that traditional epistemology can benefit in its inquiry by using the knowledge we have gained from cognitive sciences. Substantive naturalism focuses on an asserted equality of facts of knowledge and natural facts.
Neopragmatism is a variant of pragmatism that infers that the meaning of words is a result of how they are used, rather than the objects they represent.
Metaphysical naturalism is a philosophical worldview which holds that there is nothing but natural elements, principles, and relations of the kind studied by the natural sciences. Methodological naturalism is a philosophical basis for science, for which metaphysical naturalism provides only one possible ontological foundation. Broadly, the corresponding theological perspective is religious naturalism or spiritual naturalism. More specifically, metaphysical naturalism rejects the supernatural concepts and explanations that are part of many religions.
Mario De Caro is an Italian philosopher, professor of moral philosophy at the University of Rome III in Italy. Since 2000, he has also been teaching at Tufts University, where he is regularly a visiting professor. He is interested in moral philosophy, the free-will controversy, theory of action, history of science, Donald Davidson's and Hilary Putnam's philosophies, and early modern philosophy. With David Macarthur, he has defended a metaphilosohical view called liberal naturalism.
Quietism in philosophy sees the role of philosophy as broadly therapeutic or remedial. Quietist philosophers believe that philosophy has no positive thesis to contribute; rather, it defuses confusions in the linguistic and conceptual frameworks of other subjects, including non-quietist philosophy. For quietists, advancing knowledge or settling debates is not the job of philosophy, rather philosophy should liberate the mind by diagnosing confusing concepts.
Metaphysics is the branch of philosophy that investigates principles of reality transcending those of any particular science. Cosmology and ontology are traditional branches of metaphysics. It is concerned with explaining the fundamental nature of being and the world. Someone who studies metaphysics can be called either a "metaphysician" or a "metaphysicist".
The following outline is provided as an overview of and topical guide to metaphysics:
In philosophy, naturalism is the idea that only natural laws and forces 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 the philosophies.
David Macarthur is an Australian philosopher and Professor of Philosophy at the University of Sydney who works primarily on skepticism, metaphysical quietism, pragmatism, liberal naturalism and philosophy of art. He has taken up these and other themes in articles on the philosophy of Stanley Cavell, Hilary Putnam, Richard Rorty and Ludwig Wittgenstein.
Terry P. Pinkard is an American philosopher and professor at Georgetown University. His research and teaching focus on the German tradition in philosophy from Kant to the present.
