Howard Jacobson in New Statesman:
If I were to give this essay a title, it would be “Waiting for Calvin”. Not John Calvin the theologian, nor Calvin Klein the fashion designer, but Calvin, a Navajo baby whose first laugh I travelled to Arizona in 1995 to film as part of a series of television programmes I was making about comedy. It’s a nerve-racking business waiting for a baby to laugh, particularly if you have a camera crew standing by in another state, but Calvin’s laugh was as important to my film as it was to his family and community. The Navajo celebrate a baby’s first laugh as a rite of passage, a moment in which the baby laughs himself, as it were, out of inchoate babydom and into conscious humanity. It’s a wonderful concept and grants a primacy to laughter that we, who probably laugh too automatically and certainly far too much, would do well to think about. If it’s laughter that makes us human, or at least kick-starts the process of our becoming human, what does that say about what being human is?
It is sometimes argued that laughter is what distinguishes us from animals, but not everyone would agree that we have laughter to ourselves. Thomas Mann, for example, wrote an essay about his dog Bashan in which he made a claim for Bashan’s demonstrating many of the signs of mirth. And that’s before we get on to the tricky question of internal laughter – that appreciation of ironical mishap or absurd situation that even in human beings doesn’t always issue in a smile, never mind a laugh. Laughter, we can say, is an act of comprehension – whether immediate or arising out of rumination – but which of us can know for sure how much animals comprehend of what they see and how long they go on thinking about it?
