"Everything I own I carry with me":

that's how Stilpo (4th Century  BC)  answered Demetrius the besieger, who had just conquered Megara. The tyrant was surprised to see that Stilpo, unlike all his fellow citizens, was walking away from the saked city taking nothing with him. That's how this phrase has endured throughout history to sum up us succinctly as possibli the idea of someone who maintains that the only things we really own, and that nobody can take away from us, are our intellingence and our dignity.
