|Reality, philosophy: A. It is controversial, which should be counted to reality, that is to say, the set of objects and states which occur in the world. Theories differ strongly regarding the definitions of facts and situations or the consideration of internal states of subjects. Thus, a situation can be described in many ways, whereby very different assumptions about the involved objects and relations come into play. See also ontology, realism, recognition, epistemology, constructivism, facts, situations, internal/external, totality, relations, simulation.
B.Reality is an expression for the totality of what is opposed to the perception of subjects and not only imagined. In this sense, reality is what is independent of us; on the other hand, some authors regard their formability as proof of their existence. See also dependence, independence, possibility, necessity, actualism, realism, idealism, constructivism, present, simulation, aboutness, circularity, objects, things, order._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

David Deutsch on Reality - Dictionary of Arguments
Criterion for reality: something that can hit back exists. But also Dr. Johnson did not directly hit the stone. He just hit some nerves, and so on.
Def Reality/Deutsch: if a quantity is complex and autonomous according to the simplest explanation, then it is real.
Theory: the more fundamental a theory is, the more comprehensive are the observations that play a role in it. Physical reality is therefore self-similar in several ways.
After all, not everything that is real must be easy to identify.
Simulation: A reality simulator indirectly conveys both internal and external experiences to the recipient, but it cannot be programmed to simulate a particular internal experience. Roulette example and tennis example: the framework conditions are defined here, the course of the game must be open, which means that the abstract laws themselves and not only their predictive power can be simulated in virtual reality.
Life = simulation: are both embodiments of theories about the environment
Something that only exists in the laws of classical physics does not exist in reality.
Real hurricanes and butterflies obey the laws of quantum theory, not those of classical mechanics!
Plato's apparent refutation that the methods of natural science could lead to mathematical truth: we cannot know anything about perfect circles because we only have access to imperfect circles.
DeutschVsPlato: then we can also only build inaccurate tool machines, because the first ones are built with inaccurate tools. So there would be no possibility of self-correction._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
