Action as an Axiom

Ayn Rand, in Introduction to Objectivist Epistemology, identifies three axioms.  An axiom is something that cannot be denied without affirming its truth.  The three axioms were existence, the law of identity, and consciousness.

There were also corollaries, or derivatives, of these axioms.  One was the law of causality, which is the law of identity applied to action.  The existence of entities, of things, is another corollary axiom. 

I would like add one more to this: motion, or action. Motion is as fundamental a part of reality as entities are.  An action definitely cannot exist without entities, without things that act, but neither can entities exist without action.  In reality stillness does not exist.  It is common to think of motion as less real, less concrete, more ephemeral, than an entity.  But in fact motion is as real as the
entity, as a property of it.  It is another fundamental aspect of existence.  The two, entities and actions, or matter and motion, cannot be separated.

Stillness is an illusion.  Everything that we perceive as still is actually moving.  Perception is indeed an action.  It is only the movement of one thing relative to the movement of another thing that creates the appearance of stillness.  Everyone used to believe Earth was flat, and that it stood still.  It's only relative to us that it appears to be still.  It is the same when driving a car next to another vehicle moving at the same speed, it's the other car that appears to be still and everything else appears to be moving.

It is these types of 'illusions' that lead us to believe that we could perceive stillness with our senses, that we could 'see' something that was still.  It is the belief in motion as ephemeral and unreal that lead us to believe that our consciousness was an entity, ie. a thing, an object.  I believe that these ideas about motion and consciousness are wrong.
