Wolff (1679-1754) was a German rationalist philosopher, who lectured in physics, mathematics, and natural philosophy in Halle during the first two decades of the eighteenth century, but fell out of favor for holding impious views. He was removed from his chair in 1723, and did not return until 1740, at the accession of Frederick the Great. In the years between he taught at Marburg. Wolff’s philosophy was a variation of Leibnitz's ideas, retaining the idea that philosophy was the science of the possible, divided into the theoretical and the practical. This viewpoint held until the ideas of Kant displaced them.
