The Odd corners of scholarship, so very often dusty and unrewarding to the researcher, occasionally provide a forgotten knickknack which completes the décor of a period room. Seventeenth-century scholasticism is for most of us a period room, whose pieces such as triposes, disputations, declamations, quadragesimals, clerums, and so on, we find too uncomfortable for our twentieth-century use and perhaps a bit too ugly for our ranch-style academic taste. To brighten the room a bit, even for themselves, the seventeenth-century Cambridge scholastics made use of a harmless piece of bric-a-brac called the prevarication or varier's speech. It is a tragedy that most of these are now lost, for with proper evaluation a history of seventeenth-century thought might almost be written from them alone.
