Cogito ergo sum. Latin, written by Rene Descartes, meaning, “I think; therefore I am.”
Look at the derivation of the first word: cogito. It is made from two words: [1] c0, meaning “together” and [2] agitare, meaning “to shake.” So the word “think” is, metaphorically speaking, “to shake together.”
Philosophically, if you are not shaking up things, you aren’t living. I shake things up; therefore I am.
Some folks may live and learn, but by the time they’ve learned it’s usually too late to live.
