Jakob Thomasius (/toʊˈmeɪʃəs/; Latin: Jacobus Thomasius; 27 August 1622 – 9 September 1684) was a German academic philosopher and jurist. He is now regarded as an important founding figure in the scholarly study of the history of philosophy. His views were eclectic, and were taken up by his son Christian Thomasius.
Work
Thomasius was influential in the contemporary realignment of philosophy as a discipline. Martin Mulsow writes:[1]
According to Thomasius’ “Schediasma historicum” of 1665, from a theological point of view, philosophy needed to guarantee a clear separation of Creator from Creation, of God from Nature. It should thus only spring from ChristianAristotelianism, not from Stoicism or Neoplatonism.
He was the teacher of Gottfried Leibniz at the University of Leipzig, where Thomasius was professor of Rhetoric and Moral Philosophy, remaining a friend and correspondent up until the early 1670s, and has been described as Leibniz's mentor.
From 1653, Jacob Thomasius was married to Maria Weber, daughter of Archdeacon of St. Nicholas's Church and the extraordinary professor of the university Jeremiah Weber. Their children were the famous philosopher and lawyer Christian Thomasius (1655–1728), Doctor of medicine and physician in Nuremberg Gottfried Thomasius (born 1660) and Johanna (born 1663) – later the wife of professor of poetry and director of the University library in Leipzig Joachim Feller (1638–1691). Since Maria Weber died a few days after giving birth to her daughter, in 1664 Jacob Thomasius remarried with the widow of the rector of St. Peter's School. Nicholas was born Maria Elisabeth Hornschuh, nee Eichhorn, which brought him six more daughters and one son; among them, Maria Elisabeth (born 1665), was the wife of Leipzig professor of theology Adam Rechenberg [de] (1642–1721).
