evidence: You’ve probably read this quote before: "You are what you repeatedly do. Wise words from the sage Aristotle. Except for two problems. [...] The entire "You are what you do" quote that everyone knows comes not from Aristotle but from the great historian Will Durant, in his summarizing of the Aristotle passage. [...] The problem is with the innocent phrase: "You are what you repeatedly do." It reminds me a lot of that famous statement of modern Western philosophy, "Cogito ergo sum." I think, therefore I am.
