Axiom of Causality

From Wikipedia, the free encyclopedia

The Axiom of Causality is the proposition that everything in the universe has a cause and is thus an effect of that cause. This means that if a given event occurs, then this is the result of a previous, related event. If an object is in a certain state, then it is in that state as a result of another object interacting with it previously. For example, if a baseball is moving through the air, it must be moving this way because of a previous interaction with another object, such as being hit by a baseball bat.

An epistemological axiom is a self-evident truth. Thus the "Axiom of Causality" implicitly claims to be a universal rule that is so obvious that it does not need to be proved to be accepted. Even among epistemologists, the existence of such a rule is controversial. See the full article on Epistemology.

[edit] Spontaneity

One implication of the Axiom is that if a phenomenon appears to occur without any observable external cause, there must be an internal force or mechanism causing the phenomenon. Quantum mechanics appears to violate the Axiom because elementary particles exhibit behavior without any observable external cause, and no internal mechanisms have yet been observed within them.

[edit] Variation

Another implication of the Axiom is that all variation in the universe is a result of the logical and continual application of the physical laws. Specifically, all effects in the universe are the logical result of the transfer of energy from one form to another, from one place to another, and the outcome is dictated by the rules of the universe.

The baseball flies through the air because the bat imparted kinetic energy to the ball. An object can accelerate without being imparted energy from another object, but if so then according to the laws of thermodynamics, it must be consuming its own stored energy through an internal mechanism. Magnets may appear to violate this because they seem to cause acceleration without depleting an energy reservoir; but that forgets the energy content of the magnetic field.

[edit] Determinism

If all causes have effects, and all effects logically follow the rules of the universe, then all events follow a theoretically predictable pattern, thus all future events have already been determined by past events. See the full article on Determinism.

[edit] First Cause

If all effects are the result of previous causes, forming a logical chain of events, then the cause of a given effect must itself be the effect of a previous cause, which itself is the effect of a previous cause, and so on. Therefore if one could trace each cause to the one before it, this process would go on forever, with each event being the result of a previous event. This runs contrary the the human intuition that everything has a beginning and an end. See the full article on Cosmogony.
