How did Friedrich Wilhelm Joseph von Schelling distinguish negative philosophy from positive philosophy?

In his later philosophy, Friedrich Wilhelm Joseph von Schelling distinguished between two approaches to understanding the divine and reality:1

• Negative Philosophy: This approach develops the idea of God using reason alone. It identifies the conditions necessary for thought, similar to the systems found in rationalism and the philosophy of Hegel.12
• Positive Philosophy: In contrast, this approach demonstrates the reality of the idea of God by reasoning a posteriori from the existence of the world to God as its creator. It is premised on the existence of a free, creative God and delineates the conditions through which both thought and reality can exist.12

Schelling argued that while negative philosophy is necessary to establish the logical conditions for thinking, it is insufficient on its own. By incorporating positive philosophy, he sought to move beyond the limitations of pure concepts and address the reality of existence itself.2
