In this sense, there can be matter without biological life, whereas life is built upon matter zumospin casino and depends on it. 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. Anti-realism, by contrast, holds that certain aspects of reality depend on mental processes, subjective perspectives, or social conventions.
For example, David Lewis’s modal realism asserts that there exist countless spatiotemporally unified possible worlds, each just as real as the actual world. 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. In a narrow sense, being contrasts with becoming, and denotes stable or permanent aspects of reality.
- Various criteria for distinguishing real from unreal entities have been proposed, including causal powers, mind-independence, and being non-illusory.

- Various theories of the mereological principles underlying composition have been proposed.
- It comprises beliefs, ideas, and attitudes that form a background against which people interpret experiences, make decisions, and navigate life.
- Another view maintains that they are real as digital objects with genuine existence and causal powers, residing within and being constituted by computational processes.
In a slightly different sense, reality is not the totality itself but an aspect shared by all its constituents. Contemporary technology in the form of augmented and virtual reality can inform experience and raises questions about the ontological status of virtual objects. Various criteria for distinguishing real from unreal entities have been proposed, including causal powers, mind-independence, and being non-illusory. It is often contrasted with appearance, opposing what is with what seems to be, although the accuracy and fundamentality of this contrast are disputed.

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. 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. Anti-realism questions the prospect of achieving a true description of a mind-independent world. Scientific realism is the view that the best scientific theories provide an accurate description of a mind-independent world.

Some philosophers, such as Alexius Meinong, hold that being is a broader concept than reality, encompassing nonexistent objects, such as merely possible or incomplete objects, in addition to real or actual ones. In the broadest sense, being is the most general category that applies to everything and contrasts only with nothingness. 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.
Viewpoints on reality
In preparation for her role, Sweeney watched interviews and spoke with Winner over Zoom and text. For instance, causality, virtue, life and justice are abstract concepts. All the same, what is abstract plays a role in everyday life and in academic research. An event that has actually happened, or a thing which really exists is said to have “reality.” Something close to reality is realistic.
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, emotivism holds that value statements express emotional attitudes of subjective approval or disapproval rather than objective facts. Realists hold that values are objective features of reality, meaning that there are mind-independent facts about whether something is good or bad, irrespective of subjective beliefs or personal preferences. Phenomenalism, a related view, reduces physical objects to collections of actual or possible sensory experiences. 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.
According to subjectivism, values depend on the attitudes and preferences of individuals. 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.

Inspired by Leibniz, David Lewis (1941–2001) developed modal realism, maintaining that possible worlds are as real as the actual world. E. Moore (1873–1958) drew on common sense and empirical science to oppose idealism, emphasizing that the world exists independently of the mind. Responding to Kant’s philosophy, the German idealists sought a unifying principle as the foundation of all reality. His student Aristotle (384–322 BCE) proposed a system of ten categories describing the fundamental constituents of reality. 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.

Reason is the ability to draw logical inferences and arrive at truths independent of immediate sensory input. Dummett concludes that, according to realism, a sentence is either true or false, while according to anti-realism, there is a third option for undecidable sentences that can be neither verified nor falsified. 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.

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. 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.
