The pantheism controversy (German: Pantheismusstreit), also known as Spinozismusstreit or Spinozastreit, refers to the 1780s debates in German intellectual life that discussed the merits of Spinoza's "pantheistic" conception of God. What became a wider cultural debate in German society started as a personal disagreement between Friedrich Heinrich Jacobi and Moses Mendelssohn over their understanding of Gotthold Ephraim Lessing's Spinozist beliefs. The difference of opinion became a wider public controversy when, in 1785, Jacobi published his correspondence with Mendelssohn.[1] This started a series of public discussions on the matter.
