Parents often say: ‘I just want my children to be happy.’ It is unusual to hear: ‘I just want my children’s lives to be meaningful,’ yet that’s what most of us seem to want for ourselves. We fear meaninglessness. We fret about the ‘nihilism’ of this or that aspect of our culture. When we lose a sense of meaning, we get depressed. What is this thing we call meaning, and why might we need it so badly?

Let’s start with the last question. To be sure, happiness and meaningfulness frequently overlap. Perhaps some degree of meaning is a prerequisite for happiness, a necessary but insufficient condition. If that were the case, people might pursue meaning for purely instrumental reasons, as a step on the road towards happiness. But then, is there any reason to want meaning for its own sake? And if there isn’t, why would people ever choose lives that are more meaningful than happy, as they sometimes do?
