A trial full of silences, contradictions, enigmas, and acts of stupidity. The acts of stupidity were the most obvious, and, because they were inexplicable, they generally coincided with the enigmas. In those halcyon days I believed that the source of enigma was stupidity. Then the other evening in the periscope I decided that the most terrible enigmas are those that mask themselves as madness. But now I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth.
