Omnipotence is an attribute which means unlimited in power - without limitations to action.
This attribute is paradoxical and can be shown as impossible through the following argument:
Question: Can an omnipotent entity, X, create a rock that X can not lift?
If yes, then X is not omnipotent; if no, then X is not omnipotent.
Therefore X is not omnipotent.
"Omnipotence" tries to define a concept only by lack of definitions.
This is where is goes wrong.
A concept is an integration,
it takes a number of entities, abstracts away certain measurements, and ends up with a new combined whole.
"Omnipotence" tries to take a concept, "ability", and integrate it with contradiction, "unbounded",
which violates the axiom of identity.
The result is a term which seems to mean something,
but is in contradiction with reality and existence and is rationally unusable.
