That's the existential problem," Fat said, "based on the concept that We are what we do, rather than, We are what we think. It finds its first expression in Goethe's Faust, Part One, where Faust says, 'Im Anfang war das Wort'. He's quoting the opening of the Fourth Gospel; 'In the beginning was the Word.' Faust says, 'Nein. Im Anfang war die Tat.' In the beginning was the Deed. From this, all existentialism comes.
