In analytic philosophy, anti-realism is a position which encompasses many varieties such as metaphysical, mathematical, semantic, scientific, moral and epistemic. The term was first articulated by British philosopher Michael Dummett in an argument against a form of realism Dummett saw as 'colorless reductionism'.
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.
Reality is the sum or aggregate of all that is real or existent within the universe, as opposed to that which is only imaginary, nonexistent or nonactual. The term is also used to refer to the ontological status of things, indicating their existence. In physical terms, reality is the totality of a system, known and unknown.
Hilary Whitehall Putnam was an American philosopher, mathematician, and 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.
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.
In the philosophy of perception and philosophy of mind, direct or naïve realism, as opposed to indirect or representational realism, are differing models that describe the nature of conscious experiences; out of the metaphysical question of whether the world we see around us is the real world itself or merely an internal perceptual copy of that world generated by our conscious experience.
A possible world is a complete and consistent way the world is or could have been. Possible worlds are widely used as a formal device in logic, philosophy, and linguistics in order to provide a semantics for intensional and modal logic. Their metaphysical status has been a subject of controversy in philosophy, with modal realists such as David Lewis arguing that they are literally existing alternate realities, and others such as Robert Stalnaker arguing that they are not.
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.
Ralph Barton Perry was an American philosopher. He was a strident moral idealist who stated in 1909 that, to him, idealism meant "to interpret life consistently with ethical, scientific, and metaphysical truth." Perry's viewpoints on religion stressed the notion that religious thinking possessed legitimacy should it exist within a framework accepting of human reason and social progress.
Romantic realism is art that combines elements of both romanticism and realism. The terms "romanticism" and "realism" have been used in varied ways, and are sometimes seen as opposed to one another.
William Pepperell Montague was a philosopher of the New Realist school. Montague stressed the difference between his philosophical peers as adherents of either "objective" and "critical realism".
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". Coupled with this was Anderson's idea that "every fact is a complex situation: there are no simples, no atomic facts, no objects which cannot be, as it were, expanded into facts." Prominent players included Anderson, 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. David Malet Armstrong "suggested, half-seriously, that 'the strong sunlight and harsh brown landscape of Australia force reality upon us'".
Speculative realism is a movement in contemporary Continental-inspired philosophy that defines itself loosely in its stance of metaphysical realism against its interpretation of the dominant forms of post-Kantian philosophy.
The philosophy of color is a subset of the philosophy of perception that is concerned with the nature of the perceptual experience of color. Any explicit account of color perception requires a commitment to one of a variety of ontological or metaphysical views, distinguishing namely between externalism/internalism, which relate respectively to color realism, the view that colors are physical properties that objects possess, and color fictionalism, the view that colors possess no such physical properties.
The philosophy of film is a branch of aesthetics within the discipline of philosophy that seeks to understand the most basic questions about film. Philosophy of film has significant overlap with film theory, a branch of film studies.
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.
Graham Harman is an American philosopher. He is Distinguished Professor of Philosophy at the Southern California Institute of Architecture in Los Angeles. His work on the metaphysics of objects led to the development of object-oriented ontology. He is a central figure in the speculative realism trend in contemporary philosophy.
Maurizio Ferraris is an Italian continental philosopher and scholar, whose name is associated especially with the philosophical current named "new realism"—Ferraris wrote the Manifesto of New Realism in 2012, which was published by SUNY Press in 2014) -- which shares significant similarities with speculative realism and object oriented ontology.
Edward Gleason Spaulding was an American philosopher from Burlington, Vermont. He is a proponent of New Realism and co-wrote The New Realism.
Franca D'Agostini is an Italian philosopher.
