Reality Definition and 435 Threads

Reality is the sum or aggregate of all that is real or existent within a system, as opposed to that which is only imaginary. The term is also used to refer to the ontological status of things, indicating their existence. In physical terms, reality is the totality of a system, known and unknown. Philosophical questions about the nature of reality or existence or being are considered under the rubric of ontology, which is a major branch of metaphysics in the Western philosophical tradition. Ontological questions also feature in diverse branches of philosophy, including the philosophy of science, philosophy of religion, philosophy of mathematics, and philosophical logic. These include questions about whether only physical objects are real (i.e., Physicalism), whether reality is fundamentally immaterial (e.g., Idealism), whether hypothetical unobservable entities posited by scientific theories exist, whether God exists, whether numbers and other abstract objects exist, and whether possible worlds exist.

    What is your take on random vs deterministic reality

    Do you think that 'deterministic' properties we observe in universe are subset/emergent from 'random/chaotic' reality or that 'random/chaotic' behavior is a subset of purely 'deterministic' reality? What is the strongest proof you would present to support what you belief?

    Does Reality Exist Beyond Our Perceptions?

    Is Relativity an Illusion or Reality?

    Is the Changing Clock Rate in Relativity Directionally Dependent?
