The pantheism controversy (), 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. This started a series of public discussions on the matter. Benjamin Crowe of Boston University stated in a 2008 paper that: "The leading luminaries of late eighteenth and early-nineteenth German letters, people such as Herder, Goethe, Hegel, Schelling and Schleiermacher, all, in one way or another, were shaped by the ‘Pantheism Controversy’." And in Michael Forster's own words (2010), "During the last quarter or so of the eighteenth century and then well into the nineteenth century a wave of neo-Spinozism swept through German philosophy and literature: in addition to Lessing and Herder, further neo-Spinozists included Goethe, Schelling, Hegel, Schleiermacher, Hölderlin, Novalis, and Friedrich Schlegel. This wave was largely a result of Herder's embrace of neo-Spinozism in God: Some Conversations (and in Goethe's case, Herder's sympathy with Spinozism even before that work)." History A conversation between the German philosopher Friedrich Heinrich Jacobi and the German dramatist Gotthold Ephraim Lessing in 1780 led Jacobi to a protracted study of Baruch Spinoza's works. Lessing had avowed that he knew no philosophy, in the true sense of that word, save Spinozism. Jacobi's Über die Lehre des Spinozas (1st ed. 1785, 2nd ed. 1789) expressed sharply and clearly his strenuous objection to a dogmatic system in philosophy, and drew upon him the vigorous enmity of the Berlin group, led by Moses Mendelssohn. Jacobi claimed that Spinoza's doctrine was pure materialism, because all Nature and God are said to be nothing but extended substance. This, for Jacobi, was the result of Enlightenment rationalism and it would finally end in absolute atheism. Mendelssohn disagreed with Jacobi, saying that there is no actual difference between theism and pantheism. The entire issue became a major intellectual and religious concern for European civilization at the time, which Immanuel Kant rejected, as he thought that attempts to conceive of transcendent reality would lead to antinomies in thought. Legacy Jacobi was ridiculed for trying to reintroduce into philosophy the antiquated notion of unreasoning belief, was
