Another structural feature concerns the idea that some entities depend on, or are grounded in, other entities. Mereological universalism holds that any collection of entities constitutes a whole, even if the entities are otherwise unrelated. Various theories of the mereological principles underlying composition have been proposed. Various categories of being or constituents of reality are discussed in the academic discourse.
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.
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.
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.

- Realism and anti-realism are families of views concerning the mind-independence of reality.
- 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.
- The structure of reality concerns the fundamental patterns of being, describing how entities are organized and interact with each other.
- Inspired by Leibniz, David Lewis (1941–2001) developed modal realism, maintaining that possible worlds are as real as the actual world.
- 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.
- A different view suggests that reality is made up of many worlds that exist in parallel to one another, each representing a distinct way of how things could have been.
- Becoming, by contrast, covers change, like when an entity shifts from one state of being to another.
It holds that the debate is not based on a substantive disagreement but arises instead from conceptual confusions. Relativism, another form of anti-realism, holds that what counts as real varies based on one’s perspective or conceptual framework. For example, metaphysical idealism asserts that everything is essentially mental, for instance, by understanding material objects as ideas in the mind. The widely accepted Big Bang theory holds that the universe began about 13.8 billion years ago, initially in an extremely hot, dense state, expanding and cooling ever since.
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 being.
- Naturalism argues that values are part of the natural world and can be studied by the natural sciences through empirical observation.
- It is frequently possible to understand the essence of something without knowing whether it exists.
- 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.

The term reality overlaps with various related concepts, such as being, existence, world, actuality, and truth. This view contrasts being real with being fake, like the distinction between a real duck and a fake one used as a decoy. In a broad sense, appearances are not limited to what people perceive but can also include memories, beliefs, and thoughts. Debates between realists and anti-realists span multiple domains, addressing the objective existence of universals, abstract objects, values, and unobservable entities posited by scientific theories. The concept of reality overlaps with notions such as being, existence, world, actuality, and truth.
Levels of reality
The reality–virtuality continuum is a theoretical framework that posits a continuous scale of mixed reality forms. It denies the existence of knowledge in any form or domain, arguing that knowledge is impossible. These limitations indicate a gap whereby reality is not fully captured and exceeds knowledge.
According to a common view, concrete objects exist in space and time, such as a flower, a horse, and a ship. Events are proposed constituents of reality that occur in time, such as the discovery of penicillin and the Second World War. 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. Similarly, the many-worlds interpretation of quantum physics suggests that in quantum measurements, not only one but all possible outcomes occur, interpreted as a branching of the universe into multiple worlds. It is frequently possible to understand the essence of something without knowing whether it exists.
On this view, higher levels show greater complexity and new phenomena but depend on the lower ones and could not exist without them. Some philosophical approaches rely on the idea of fundamentality and dependence to analyze the world in terms of levels or layers, such as material, biological, psychological, and social reality. In the Hindu tradition, it mister golden is often identified with Brahman as the all-pervasive reality and the supreme principle grounding all being.
A worldview is a comprehensive framework for understanding reality and humanity’s place within it. Another view maintains that they are real as digital objects with genuine existence and causal powers, residing within and being constituted by computational processes. Similarly, virtual reality worlds may incorporate real-world objects into the simulation or be entirely virtual.l
