An anachronism, in the relevant sense, is a thing that appears in an age for which it is not suited, like a sword in the age of fighter jets. An anachronist, on the other hand, is a person who refuses to blindly embrace the fashions and modes of life characteristic of his time. That, he says, would be a temporal prejudice; a more enlightened view would find that the past contains treasures which have been lost to us, but which can–so we hope–be recovered.
