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.
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.
- Other suggested criteria identify reality with what is observable, measurable,a coherent,b useful, objective, intersubjective, or fundamental.
- Causal determinism is the view that every event is fully determined or necessitated by prior events.
- 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.
- Various criteria for distinguishing real from unreal entities have been proposed, including causal powers, mind-independence, and being non-illusory.
- Fictionalists argue that discourse about abstract objects concerns fictional entities within make-believe frameworks.
- Testimony is a transmission of knowledge from one person to another through communication.k
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.
Values
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.
- It characterizes realism as the view that the truth or meaning of sentences is determined by external standards or mind-independent reality.
- It holds that the scientific view of the world is either exactly or at least approximately true by presenting reality as it is.
- Although it is not a widely accepted position, various thought experiments undermining the reliability of human cognitive faculties are discussed in the academic literature.
- A worldview is a comprehensive framework for understanding reality and humanity’s place within it.
- By contrast, Arthur Schopenhauer (1788–1860) criticized German idealism and held that a blind, irrational will is the underlying principle of reality.
- Anti-realism rejects this view, arguing instead that there is no external world or that reality depends in certain respects on mental processes, subjective perspectives, or social conventions.
- Various theories of the mereological principles underlying composition have been proposed.
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.

Inspired by Leibniz, David Lewis (1941–2001) developed modal realism, maintaining that possible worlds are as real as the actual world. Responding to Kant’s philosophy, the German idealists sought a unifying principle as the foundation of all reality. Inspired by Plato’s realm of forms, Plotinus (c. 204 – c. 270 CE) identified the One as the supreme principle underlying all of reality. His student Aristotle (384–322 BCE) proposed a system of ten categories describing the fundamental constituents of reality. In ancient Greek philosophy starting in the 6th century BCE, the pre-Socratics discussed the first principles from which all things arise. 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.
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.
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 mister golden 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.
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.
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
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.
