Australian realism, also called Australian materialism, is a school of philosophy that flourished in the first half of the 20th century in several universities in Australia including the Australian National University, the University of Adelaide, and the University of Sydney, and whose central claim, as stated by leading theorist John Anderson, was that "whatever exists … is real, that is to say it is a spatial and temporal situation or occurrence that is on the same level of reality as anything else that exists". [1] : p1 Coupled with this was Anderson's idea that "every fact (which includes every “object”) is a complex situation: there are no simples, no atomic facts, no objects which cannot be, as it were, expanded into facts." [2] Prominent players included Anderson, [3] : p52 David Malet Armstrong, J. L. Mackie, Ullin Place, J. J. C. Smart, and David Stove. The label "Australian realist" was conferred on acolytes of Anderson by A. J. Baker in 1986, to mixed approval from those realist philosophers who happened to be Australian. [4] : p188 David Malet Armstrong "suggested, half-seriously, that 'the strong sunlight and harsh brown landscape of Australia force reality upon us'". [5]
Australian realism began after John Anderson accepted the Challis Chair of Philosophy at the University of Sydney in 1927. His students included philosophers such as John Passmore, J. L. Mackie, David Stove, Eugene Kamenka and David Malet Armstrong. Anderson viewed philosophy historically as a long argument beginning with Thales. Anderson proposed that there was nothing more to being than the spatio-temporal system and that a correct and coherent view of the world involved not only rejecting any sort of deity, but also the extraordinary entities postulated by so many philosophers, from at least the time of Plato to the present day.

Independently from the Andersonians, in Adelaide during the 1950s, the mind–brain identity theory was being developed by two former students of Gilbert Ryle, J. J. C. Smart (then Chair of Philosophy at the University of Adelaide) and Ullin Place. [6] : ch9
(1) All entities exist in spatio-temporal 'situations'. 'Situations' are all that exist. All situations have the same ontological status. There are no 'levels' of reality.
(2) All situations have a propositional form — that is, all situations have the form of "A is B".
(3) Reality is infinitely complex and plural. Every fact (which includes every “object”) is a complex situation: there are no simples, no atomic facts, no objects which cannot be expanded into facts.
(4) All situations exist independent of knowledge of them.
(5) Determinism: all entities — objects, events, situations — are caused.
(6) Ethics is concerned with establishing and describing what is Good. This is a positive science. It is not normative. [7]
James Franklin and the "Sydney School" develop the Anderson-Armstrong "one level of reality" view into a philosophy of mathematics that is opposed to both Platonism and nominalism. Their Aristotelian realist philosophy of mathematics holds that mathematics studies properties such as symmetry, continuity and order that can be immanently realized in the physical world (or in any other world there might be).
In analytic philosophy, anti-realism is the position that the truth of a statement rests on its demonstrability through internal logic mechanisms, such as the context principle or intuitionistic logic, in direct opposition to the realist notion that the truth of a statement rests on its correspondence to an external, independent reality. In anti-realism, this external reality is hypothetical and is not assumed.
Metaphysics is the branch of philosophy that examines the basic structure of reality. It is often characterized as first philosophy, implying that it is more fundamental than other forms of philosophical inquiry. Metaphysics is traditionally seen as the study of mind-independent features of the world, but some modern theorists understand it as an inquiry into the conceptual schemes that underlie human thought and experience.
In metaphysics, nominalism is the view that universals and abstract objects do not actually exist other than being merely names or labels. There are at least two main versions of nominalism. One version denies the existence of universals – things that can be instantiated or exemplified by many particular things. The other version specifically denies the existence of abstract objects – objects that do not exist in space and time.
Ontology is the philosophical study of being. As one of the most fundamental concepts, being encompasses all of reality and every entity within it. To articulate the basic structure of being, ontology examines what all entities have in common and how they are divided into fundamental classes, known as categories. An influential distinction is between particular and universal entities. Particulars are unique, non-repeatable entities, like the person Socrates. Universals are general, repeatable entities, like the color green. Another contrast is between concrete objects existing in space and time, like a tree, and abstract objects existing outside space and time, like the number 7. Systems of categories aim to provide a comprehensive inventory of reality, employing categories such as substance, property, relation, state of affairs, and event.
The problem of universals is an ancient question from metaphysics that has inspired a range of philosophical topics and disputes: "Should the properties an object has in common with other objects, such as color and shape, be considered to exist beyond those objects? And if a property exists separately from objects, what is the nature of that existence?"
Process philosophy, also ontology of becoming, or processism, is an approach in philosophy that identifies processes, changes, or shifting relationships as the only real experience of everyday living. In opposition to the classical view of change as illusory or accidental, process philosophy posits transient occasions of change or becoming as the only fundamental things of the ordinary everyday real world.
In metaphysics, a universal is what particular things have in common, namely characteristics or qualities. In other words, universals are repeatable or recurrent entities that can be instantiated or exemplified by many particular things. For example, suppose there are two chairs in a room, each of which is green. These two chairs share the quality of "chairness", as well as "greenness" or the quality of being green; in other words, they share two "universals". There are three major kinds of qualities or characteristics: types or kinds, properties, and relations. These are all different types of universals.
John Jamieson Carswell Smart was a British-Australian philosopher who was appointed as an Emeritus Professor by the Australian National University. He worked in the fields of metaphysics, philosophy of science, philosophy of mind, philosophy of religion, and political philosophy. He wrote several entries for the Stanford Encyclopedia of Philosophy.
In logic and philosophy, a property is a characteristic of an object; a red object is said to have the property of redness. The property may be considered a form of object in its own right, able to possess other properties. A property, however, differs from individual objects in that it may be instantiated, and often in more than one object. It differs from the logical/mathematical concept of class by not having any concept of extensionality, and from the philosophical concept of class in that a property is considered to be distinct from the objects which possess it. Understanding how different individual entities can in some sense have some of the same properties is the basis of the problem of universals.
In philosophy of perception and epistemology, naïve realism is the idea that the senses provide us with direct awareness of objects as they really are. When referred to as direct realism, naïve realism is often contrasted with indirect realism.
Philosophical realism – usually not treated as a position of its own but as a stance towards other subject matters – is the view that a certain kind of thing has mind-independent existence, i.e. that it exists even in the absence of any mind perceiving it or that its existence is not just a mere appearance in the eye of the beholder. This includes a number of positions within epistemology and metaphysics which express that a given thing instead exists independently of knowledge, thought, or understanding. This can apply to items such as the physical world, the past and future, other minds, and the self, though may also apply less directly to things such as universals, mathematical truths, moral truths, and thought itself. However, realism may also include various positions which instead reject metaphysical treatments of reality entirely.
Modal realism is the view propounded by philosopher David Lewis that all possible worlds are real in the same way as is the actual world: they are "of a kind with this world of ours." It is based on four tenets: possible worlds exist, possible worlds are not different in kind from the actual world, possible worlds are irreducible entities, and the term actual in actual world is indexical, i.e. any subject can declare their world to be the actual one, much as they label the place they are "here" and the time they are "now".
David Malet Armstrong, often D. M. Armstrong, was an Australian philosopher. He is well known for his work on metaphysics and the philosophy of mind, and for his defence of a factualist ontology, a functionalist theory of the mind, an externalist epistemology, and a necessitarian conception of the laws of nature.
The following outline is provided as an overview of and topical guide to metaphysics:
John Anderson was a Scottish philosopher who occupied the post of Challis Professor of Philosophy at Sydney University from 1927 to 1958. He founded the empirical brand of philosophy known as Australian realism.
In the philosophy of science, structuralism asserts that all aspects of reality are best understood in terms of empirical scientific constructs of entities and their relations, rather than in terms of concrete entities in themselves.
Relations are ways in which several entities stand to each other. They usually connect distinct entities but some associate an entity with itself. The adicity of a relation is the number of entities it connects. The direction of a relation is the order in which the elements are related to each other. The converse of a relation carries the same information and has the opposite direction, like the contrast between "two is less than five" and "five is greater than two". Both relations and properties express features in reality with a key difference being that relations apply to several entities while properties belong to a single entity.
Donald Cary Williams, usually cited as D. C. Williams, was an American philosopher and a professor at both the University of California Los Angeles and at Harvard University.
Australian philosophy refers to the philosophical tradition of the people of Australia and of its citizens abroad. Academic philosophy has been mostly pursued in universities. It has been broadly in the tradition of Anglo-American analytic philosophy, but has also had representatives of a diverse range of other schools, such as idealism, Catholic neo-scholasticism, Marxism, and continental, feminist and Asian philosophy.
In the philosophy of mathematics, Aristotelian realism holds that mathematics studies properties such as symmetry, continuity and order that can be immanently realized in the physical world. It contrasts with Platonism in holding that the objects of mathematics, such as numbers, do not exist in an "abstract" world but can be physically realized. It contrasts with nominalism, fictionalism, and logicism in holding that mathematics is not about mere names or methods of inference or calculation but about certain real aspects of the world.
