V. The World Conceptions of the Modern Age of Thought Evolution

We take our stand at a point where the various threads of the development of modern world conceptions intertwine, as it were, when we observe how the current of Spinoza's thought enters into it in the eighties of the eighteenth century. In 1785 F. H. Jacobi published his “Spinoza-Booklet.” In it he relates a conversation between himself and Lessing that took place shortly before Lessing's death. According to this conversation, Lessing had confessed his adherence to Spinozism. For Jacobi, this also establishes Lessing's atheism. If one recognizes the “Conversation with Jacobi” as decisive for the intimate thoughts of Lessing, one must regard him as a person who acknowledges that man can only acquire a world conception adequate to his nature if he takes as his point of support the firm conviction with which the soul endows the thought living through its own strength. With such an idea Lessing appears as a person whose feeling prophetically anticipates the impulses of the world conceptions of the nineteenth century. That he expresses this idea only in a conversation shortly before his death, and that it is still scarcely noticeable in his writings, shows how hard, even for the freest minds, the struggle with the enigmatic questions that the modern age raised for the development of world conceptions became.
