“ What do you think it is that makes a manI started on the Definition. He cut me of after five words.It is not! he said. A wax figure could have all that, and he'd still be a wax figure, wouldn't he? ...Well, then, what makes a man a man is something inside him.A soul? I suggested.No... souls are just counters for churches to collect, all the same value, like nails. No, what makes man man is mind; it's not a thing, it's a quality, and minds aren't all the same value; they're better or worse, and the better they are, the more they mean. ”
