My first reaction on reading a review of Charles Foster’s Being a Beast: Adventures across the Species Divide was amazed laughter. The idea of a middle-aged man attempting to live like a badger, sleeping all day in a tunnel underground, crawling through the woods on all fours at night in search of sustenance; or haunting the river’s depths, trying to catch fish in his teeth like an otter, struck me as courageous, yet absurd.
When I actually read Foster’s book, what I found was a deeply moral work: a frank and often funny account of the demanding physical and emotional attempts he made to enter the day-to-day reality of four other species: badger, otter, urban fox and red deer. His adventures, he explains, reflect the principle of “theory of mind” — the ability to think oneself into another person’s position; in his case, not just putting himself in someone else’s shoes, but into another creature’s hooves, pads or fins.
