Men plot, God Laughs, so goes a Yiddish saying.
Philosophers might say we find ourselves at an epistemological disadvantage. We know our experiences and machinations can be more about appearance than reality. We can be mistaken about what we've seen and what we've heard. How else do you explain unrequited love? It is not without reason that Shakespeare wrote,
“Love looks not with the eyes, but with the mind; And therefore, is wing’d Cupid painted blind” (A Midsummer Night’s Dream).
But let not your hearts be troubled. Life may be messy. It may be difficult, if not impossible, to see all ends, but it does not follow that the darkness about us is complete and total.
"Life is a Pigsty. And if you don't know this, then what do you know?" ― Morrissey
“For even the very wise cannot see all ends.” ― J. R. R. Tolkien
