>"Every rule has an exception".
If we assume that to be true, and to be a rule, we must conclude that it, as well, has an exception.
But if every rule has an exception, and this is true, there can be no rule without exception; therefore, it is a rule with no exceptions. Which makes it, coincidentally, the exception of its own rule.
But if it is true that this rule has no exceptions, it betrays itself in that it affirms that every rule has one.
However, it is also truthful in that having no exceptions, it is its own exception.
Therefore this rule has an exception, by not having an exception.
It contains two self-contradicting premises, which are nonetheless both true and complement each other. It nullifies itself while reinforcing itself.
>"Could God make a rock so big he couldn't lift it?"
The answer is yes, he could, for he is omnipotent; and at the same time, no, he could not, for he could always lift the rock; he is omnipotent.
Both statements are self-conflicting, but at the same time, truthful. God could both make and make not the rock; as the rule both has and has not exceptions.
Such is the true meaning of omnipotence, and why the human mind cannot grasp the true form of the Divine. Only in the Pleroma, the infinite realm, can such a reality make itself understandable to our minds.
This exercise in logic is but one of the methods through which we achieve understanding of the Divine Nature. Realistically speaking, there are actually various rules with no exceptions in this reality, as is the understanding of the many sciences through which we analyze it; but in reflecting on these self-completing impossibilities, one may acquire a brief glimpse of what lies beyond the many rules which constrain the material plane; the True Logos, which is both limitless, and its own limit.
You have but glimpsed it. Strive to see it.
