-- "I think, therefore I am" ("cogito ergo sum") has never made any sense to me. It has never occurred to me for an instant to wonder whether or not I exist. I can't imagine not being sure whether or not I exist. Ergo, I don't see the use of "cogito ergo sum." Let alone why it is perhaps the most often-repeated phrase ever written by any philosopher. I don't unnerstand. And I'm not asking for you to try to explain it to me. You would only fail and exhaust us both.
And E=Mc squared. I have no idea what it means to square a velocity. Zzzoomm! Right over my munkee head.
Whew. I feel better!
