The crucial attribute that all humans have in common, he argues, is not rationality, but the fact that each of us has a life that matters to us; in other words, what happens to us matters to us, regardless of whether it matters to anyone else.
Glavna osobina koja je zajednička svim ljudima, tvrdi on, nije racionalnost, već činjenica da svatko od nas ima život do kojeg mu je stalo; drugim riječima, ono što nam se dogodi nama je bitno, bez obzira da li je bitno ikome drugomu.
