Reality means anything that is real. An event that has actually happened, or a thing which really exists is said to have "reality." Something close to reality is realistic.
Reality is the state of things as they are, rather than as they may appear or might be imagined. In a wider definition, reality includes everything that is and has been, whether or not we can see it and understand it. An even wider definition includes everything that has existed, exists, or will exist.
Reality is often contrasted with what is imaginary, delusional, in the mind, dreams, what is false, what is fictional, or what is abstract. The truth refers to what is real, while falsity refers to what is not. Fictions are not real.
All the same, what is abstract plays a role in everyday life and in academic research. For instance, causality, virtue, life and justice are abstract concepts. They are difficult to define, but they are not pure delusions.
Viewpoints on reality
- Philosophy looks at the nature of reality itself, and the relationship between the mind (as well as language and culture) and reality.
- Science: the view that the world described by science is the real world. The scientists' view of reality depends on evidence, tests and experiments, worked out by specialists. In the end, what ends up in textbooks is what an "invisible college" of scientists has agreed on. Philosophy of science and sociology of science are studies of how scientists think and work.
