Know that you don't know
The title is a statement attributed to Socrates, loosely from memory. What distinguished him from and raised him above the general opinion, the pretensions, the passions, the sympathies and the antipathies. His wisdom, his independence.
Quite often you hear similar "Socratic" statements, I think. "No one can know anything about that", etc. Something in me usually rises when I hear such things. Why? I can trace it way back, that I reacted to and wanted to object to it. "To doubt completely is to also question the doubt...", I wrote once, as an aphorism. There was a period when I tried to sort out these thoughts and feelings for myself. I remember thinking of two kinds of doubt and assigning them the words "skepticism" and "doubt". Most of it is skepticism, i.e. a slightly too certain, busy reservation about one thing or another (like, yes, "no one can know anything about that", whether it's about life after death, the existence of God, or something else). An incomplete, half-rhetorical humility. Doubt had to stand for an attitude of openness or waiting that was more pure.
More recently I wrote a text with the title "Spirituality's counterpart to physics' wave-particle duality" Cryptic title, but I was whipping around the same basic question, dilemma, thought trap.
You could content yourself with stating that you, and possibly everyone you know, don't seem to know?
