The conception of "moral responsibility" is "responsible" for much evil. Imagine two children, one of whom has the good fortune to be in a nursery school, while the other is left to unalleviated slum-life. Is the second child "morally responsible" if he grows up less admirable than the first? Are his parents "morally responsible" for the ignorance and carelessness which makes them unable to educate him?
