|J.M.E. McTaggart, who in 1908 coined |
the terms "A and B-theories of time."
Human beings seem to have an innate tendency to think that what we do not like or cannot explain does not exist. Thus in Hinduism and Buddhism, reality itself is considered an illusion (maya), something that must be discarded to achieve liberation. According to this philosophy, since it is an inseparable part of physical reality, time should also be considered as an illusion. In the Hindu Brahman and the Buddhist Nirvana, time does not exist.
In Western philosophy and science, the idea of time has traditionally been quite different. Until the eighteenth century, nobody put in question the reality of reality. As an inseparable part of reality, time was absolute. In Newtonian mechanics, time plays that role. According to his theory of gravitation, the course of time is independent of the motion of the observer. Hence one can deduce the principle of relativity of classical mechanics: when several bodies are subjected to uniform rectilinear motion (at constant speed) it is impossible to distinguish which one is at rest and which is moving.
