In Greek mythology, the Erinyes (Furies) are "the angry ones." They are chthonic (underworld) deities whose purpose is to punish crimes against the ancient "natural order": young against old; child against parent; host against guest. The furies are so terrifying that they are seldom called by name. The title of Euripides' play The Eumenides is a euphemism: "the kindly ones."
In my Christmas letter, I included a link to a video of me performing my latest work, "What is the Matter?" Apart from any question of poor judgment (guilty!) what has troubled me in some peoples' responses is what I would call a one- dimensional way of thinking about the subject of the piece: two points (terminals) linked by a shuttle. There is no place in the middle, much less a second or third dimension.
