I think this is what David Deutsch meant in 2005, when he ended his Oxford TEDTalk by saying he had two principles he'd like to share for living, and he would like to carve them on stone tablets.
Penso isto é o que David Deutsch  queria dizer em 2005, quando terminou a sua palestra TED  em Oxford dizendo que tinha dois princípios de vida que queria partilhar, e que gostaria de gravar em pedra.
