Why did Friedrich Wilhelm Joseph von Schelling criticize Johann Gottlieb Fichte’s treatment of nature?

Friedrich Wilhelm Joseph von Schelling criticized Johann Gottlieb Fichte because he believed Fichte’s philosophical system failed to take adequate notice of nature.1

While Schelling initially revered Fichte, he eventually argued that Fichte viewed nature merely as an object subordinate to humanity. In contrast, Schelling sought to demonstrate that nature, when considered in itself, possesses an active development toward the spirit. This divergence led Schelling to develop his own philosophy of nature, which posited that nature is not simply a passive backdrop for human activity but a dynamic entity with its own inherent significance.1
