Johannes Clauberg (1622-1665) was a German theologian and philosopher. He was the founding rector of the first University of Duisburg, where he taught from 1655 to 1665. He is known as a "scholastic cartesian...in Groningen ... he discovered what came to be called the reformed variation of Aristotelianism." (Wikipedia). This edition, published after the author's death, was edited by the German philosopher Paul Michael Rhegenius. A few small wormholes in the lower gutter, affecting a few letters; otherwise a very good, clean copy. Very rare. OCLS lists fewer than ten copies.
