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.
Phenomenalism, a related view, reduces physical objects to collections of actual or possible sensory experiences. In this sense, reality does not depend on human knowledge or consciousness and exists apart from them, including the aspects that no one is aware of. In the broadest sense, realism is the view that the external world and its constituents exist as they do regardless of how people perceive or think about them. Unreal entities, by contrast, depend for their existence on thoughts and ideas; they would not arise or would vanish without the mental activity creating or sustaining them. For example, if a planet or a virus is real then it exists on its own and behaves according to its nature, even if people are unaware or hold false beliefs about it.
Monism and pluralism are families of views about the roles of unity and multiplicity in the structure of reality. According to this view, even a complete understanding of physics would not render sciences dedicated to higher levels, such as psychology, obsolete. Non-reductive physicalists hold that everything is ultimately physical while insisting that higher-level psychological facts cannot be reduced to fundamental physics. In this sense, there can be matter without biological life, whereas life is built upon matter and depends on it. Lower levels, by contrast, operate according to more basic mechanisms and are prior to the higher ones.
Realism and anti-realism
Reality received 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 mister golden being.
Discussed in ancient Greek philosophy as the Eleatic principle, it states that to be real is to be able to produce changes and to be affected by them. Criteria of reality are proposed features or standards that distinguish real entities from unreal ones. In this sense, it is the state of being real or what all real entities have in common, separating them from unreal or illusory ones. In a slightly different sense, reality is not the totality itself but an aspect shared by all its constituents. 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. Contemporary technology in the form of augmented and virtual reality can inform experience and raises questions about the ontological status of virtual objects.
Levels of reality
- It holds that the scientific view of the world is either exactly or at least approximately true by presenting reality as it is.
- In Hindu philosophy, the school of Advaita Vedanta emerged in the 8th century and held that the world of everyday appearances is an illusion, contrasting it with the ultimate reality of Brahman.
- His student Aristotle (384–322 BCE) proposed a system of ten categories describing the fundamental constituents of reality.
- By contrast, Arthur Schopenhauer (1788–1860) criticized German idealism and held that a blind, irrational will is the underlying principle of reality.
- In this sense, reality does not depend on human knowledge or consciousness and exists apart from them, including the aspects that no one is aware of.
- Unreal entities, by contrast, depend for their existence on thoughts and ideas; they would not arise or would vanish without the mental activity creating or sustaining them.
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.

According to conventionalism, the truth of mathematical statements rests on linguistic conventions or definitions, rather than on their relation to language-independent reality. Anti-realism about abstract objects in mathematics takes various forms, including, but not limited to, fictionalism. Fictionalists argue that discourse about abstract objects concerns fictional entities within make-believe frameworks. Anti-realists hold that there are no abstract objects and offer alternative explanations.

- 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.
- Monism and pluralism are families of views about the roles of unity and multiplicity in the structure of reality.

- For example, emotivism holds that value statements express emotional attitudes of subjective approval or disapproval rather than objective facts.
- They examine what it means for something to be real, how entities are divided into different categories of being, and which entities exist at the most fundamental level.
Some outlooks suggest that only the fundamental level is ultimately real, arguing that non-fundamental entities are in some sense eliminable since reality can be described without them. For example, one view suggests that macroscopic objects, such as a chair, depend on the microscopic objects that underlie them, such as elementary particles. The structure of reality concerns the fundamental patterns of being, describing how entities are organized and interact with each other.
In Hindu philosophy, the school of Advaita Vedanta emerged in the 8th century and held that the world of everyday appearances is an illusion, contrasting it with the ultimate reality of Brahman. The school of Vaisheshika arose roughly in the 2nd century BCE and developed a system of six fundamental categories of being. Various historiographical debates address the question of whether a truly objective account of the past is possible. Some doctrines hold that God constitutes the most fundamental level of reality as the divine origin of all creation. One strand of the field analyzes culture-specific worldviews and compares them across societies. The simulation hypothesis is the view that the whole world and everything within it is a simulated reality, including humans.
It opposes the idea that world and mind are essentially correlated, emphasizing the mind-independent nature of reality beyond the way humans perceive and think about it. On this view, unobservable entities may be invoked in theory construction to aid prediction but should not be taken to exist. Scientific realism is the view that the best scientific theories provide an accurate description of a mind-independent world. Error theory asserts that all value statements are false because there are no values.i Another form of anti-realism maintains that value statements are neither true nor false but meaningless. According to subjectivism, values depend on the attitudes and preferences of individuals.
Values
Epistemology, another philosophical subdiscipline, explores how people can know reality. They examine what it means for something to be real, how entities are divided into different categories of being, and which entities exist at the most fundamental level. Accordingly, worldviews address not only theoretical matters but also practical and evaluative outlooks about what matters and how one should act.
