This is one of the traits of human nature, that you cannot live with a question mark. Either you have to cover it with false knowledge – which becomes your answer – or you have to find the real answer so that the question disappears.
Knowledge is not the answer but only a pretension of an answer.
You say, “Knowing perfectly well” …. Drop this idea of knowledge. Please just accept your ignorance.
Be courageous and capable of saying, of many things, “I do not know.”
If somebody asks you about God, do you have the courage simply to say, “I do not know”?
The atheist has no courage; he says, “I know there is no God.”
The theist has no courage; he says, “I know there IS God.”
Only the agnostic is a little courageous; he says, “I do not know yet.” He leaves the question without any definite answer. He is enquiring, he is searching.
