Other suggested criteria identify reality with what is observable, measurable,a coherent,b useful, objective, intersubjective, or fundamental. This view emphasizes that reality is encountered, rather than invented, and can resist or frustrate beliefs and desires, unlike malleable imaginary creations. Another influential proposal treats mind-independence as a criterion of reality, arguing that real entities do not depend on how people think about them. The Eleatic principle is controversial because it is typically taken to deny that abstract objects studied in fields like mathematics, such as numbers, are real. However, stories about Santa Claus, such as written texts in children’s books, are part of reality since they can influence how people think.
More general constraints arise from limits of human cognitive faculties rather than situation-specific circumstances, such as facts too complex for anyone to conceive. Testimony is a transmission of knowledge from one person to another through communication.k Memory is the capacity to store information from other sources and make it available to cognitive processes when needed. Reason is the ability to draw logical inferences and arrive at truths independent of immediate sensory input. Anti-realism is understood as a view that identifies the meaning of a statement with the evidence that would support it or the conditions under which a person is justified in asserting it.
- Non-reductive physicalists hold that everything is ultimately physical while insisting that higher-level psychological facts cannot be reduced to fundamental physics.
- As individual entities, they contrast with universals, which are general, repeatable entities that can have many instances, such as the color blue, the shape roundness, and the property of being a mammal.
- Theories of the nature of reality have been discussed since antiquity and continue to shape contemporary inquiry, with influential early traditions originating in ancient Indian, Chinese, and Greek thought.
- Realists and anti-realists about abstract objects debate whether, or in what sense, such entities form part of reality.
- As a team of agents arrive and begin searching the house, Winner engages in casual conversation with the agents, all of which is picked up by recording device, the transcript of which forms the basis of the film’s dialogue.
Non-naturalism, another form of realism, maintains that values differ significantly from empirical properties and belong to another domain of reality. Naturalism argues that values are part of the natural world and can be studied by the natural sciences through empirical observation. Some positions concern the existence of values in general, while others are limited to specific domains, such as moral, aesthetic, or religious values. Formalism, another form of anti-realism, understands mathematics as a practice of symbol manipulation, suggesting that mathematical truth is grounded in whether the manipulation rules permit the construction of a proof.
Realists and anti-realists about abstract objects debate whether, or in what sense, such entities form part of reality. Nominalism, another anti-realist view, rejects both mental and non-mental interpretations of universals. For example, a person may be a realist about universals and an anti-realist about values.

A related topic concerns the possibility and limits of knowledge as a successful cognitive contact with reality. Anti-realism, by contrast, holds that certain aspects of reality depend on mental processes, subjective perspectives, or social conventions. Realism is the view that reality does not depend on human knowledge or consciousness and exists apart from them. An event that has actually happened, or a thing which really exists is said to have “reality.” Something close to reality is realistic.
It is often contrasted with essence, which denotes the nature or characteristic features of an entity. A central topic in ontology is the categories of being—fundamental classes that map out a comprehensive inventory of reality. Becoming, by contrast, covers change, like when an entity shifts from one state of being to another.

It characterizes realism as the view that the truth or meaning of sentences is determined by external standards or mind-independent reality. A semantic approach to the debate between realism and anti-realism, proposed by Michael Dummett, argues that the underlying disagreement concerns the meaning of statements rather than the existence of entities. On this view, reality is made up of countless concrete worlds existing in parallel without interacting with one another.
Immanuel Kant (1724–1804) rejected the possibility of objective knowledge of the things in themselves, arguing instead that all experience is shaped by the innate structures of human cognition. Plato (c. 427 – c. 347 BCE) argued for the existence of a realm of eternal forms or ideas in addition to the material world of mutable entities. Skepticism about metaphysics holds that it is not possible to know the fundamental nature of reality, such as claims about categories of being or the existence of universals.
For example, value theory is concerned with the reality of values, and the philosophy of mathematics explores in what sense mathematical objects, like numbers and sets, form part of reality. Different worldviews offer distinct answers to existential questions about meaning, morality, and the nature of reality, such as the contrast between religious and secular worldviews. One perspective holds that such objects are illusory or unreal because they lack existence in the physical world outside the simulation.
- It comprises beliefs, ideas, and attitudes that form a background against which people interpret experiences, make decisions, and navigate life.
- It focuses on how individuals experience reality and how conscious states are intentional or directed towards entities other than themselves.
- In psychoanalytic theory, the reality principle is a proposed mechanism that counteracts the pleasure principle, delaying immediate gratification when it collides with the demands of external reality.
- Testimony is a transmission of knowledge from one person to another through communication.k
- Nominalism, another anti-realist view, rejects both mental and non-mental interpretations of universals.

Reality received mister golden positive reviews from critics at Berlinale, with praise for Satter’s direction and the cast performances (particularly Sweeney’s). In preparation for her role, Sweeney watched interviews and spoke with Winner over Zoom and text. As a team of agents arrive and begin searching the house, Winner engages in casual conversation with the agents, all of which is picked up by recording device, the transcript of which forms the basis of the film’s dialogue. Influenced by Kant, Edmund Husserl (1859–1938) argued that reality is tied to consciousness as an intersubjective correlate of experience that cannot be reduced to a wholly mind-independent substrate. In China, beginning roughly in the 9th century, Neo-Confucianism maintained that reality has a rational order expressed in the principle Li, which acts as a ground of being.
In the social sciences, critical realism holds that observable events in the social world only partially disclose reality. Local realism is a view that combines the principle of locality with the notion that there are definite physical properties, whether or not they are being observed by someone. For example, psychologism asserts that mathematical objects are mental constructions or ideas rather than abstract objects. It holds that this practice can be useful in some contexts without ascribing substantive or framework-independent reality to such entities. According to conceptualism, universals exist in the mind as concepts through which people categorize and order their impressions, acting as tools of cognitive organization rather than properties of external entities. Platonism about universals holds that they are part of reality in their own right, independent of the particular entities that instantiate them.
