Williams’s suicide demonstrates that none of us is immune. If you could be Robin Williams and still want to kill yourself, then all of us are prone to the same terrifying vulnerability. Most people imagine that resolving particular problems will make them happy. If only one had more money, or love, or success, then life would feel manageable. It can be devastating to realize the falseness of such tempered optimism. A great hope gets crushed every time someone reminds us that happiness can be neither assumed nor earned; that we are all prisoners of our own flawed brains; that the ultimate aloneness in each of us is, finally, inviolable.
