" It’s true that Darwin didn’t live the optimally utilitarian life. No one ever has. Still, as he prepared to die, he could rightly have reflected on a life decently and compassionately lived, a string of duties faithfully discharged, a painful, if only partial, struggle against the currents of selfishness whose source he was the first man to see. It wasn’t a perfect life; but human beings are capable of worse. "
