Well, there are many things I don’t pretend to understand. But one’s assessment of his/her knowledge, absolute or otherwise,is a personal thing. I’ve found it wise not to interfere with the self concepts of others.
I think we can discuss the objectivity of things without diverting ourselves into talk about anyone’s self concept.
The statement that “there are no absolutes” is usually a pretense for denying the existence of God.
But the statement itself is given as an absolute. This is what I meant about incoherence. I don’t mean it in a personal way. Simply an objective observation.
