Do Be Do Be Do

Hi guys,
I am reading Richard Precht's first philosophy book, "Who Am I? And if so, How Many?" which Jan's Aunt Uta recommended to me. It is proving a very entertaining read. I particularly like Precht's quote from a plaque on a Greek Taverna wall, which said

"To be is to do - Socrates

"To do is to be - Sartre

"Do Be Do Be Do - Sinatra" (Precht, 2011, p. 247).

Precht takes this to mean that life is not so simple as Socrates' view that being is the same as doing, nor Satre's that doing means we are; but that our lives are a constant iterative creation of doing and becoming, doing and becoming; that we can invent who we become.

I like that :-)
