“Babies know the difference between good and evil at six months, study
reveals”. I guess many of us read a heading like this in our daily paper
or online this week. Startling news. Here we were, thinking that the
newborn babe is a tiny barbarian who needs to learn his first notions of
right and wrong from his parents, when he actually arrives with an
innate sense of morality. Or so it seems.
