Why did Hegel believe philosophy would eventually supersede art?

For Georg Wilhelm Friedrich Hegel, art, religion, and philosophy are all embodiments of Absolute Spirit, representing different stages in the unfolding of human consciousness and the World-Spirit.

Hegel viewed art as a form of self-realization that provides a sensuous embodiment of the spirit, articulating its inner tensions through concrete forms like architecture, sculpture, painting, music, and poetry. However, he believed that art is inherently limited because it relies on sensuous expression to convey truth. As human civilization and the dialectical process of history evolve, the spirit requires a more sophisticated medium to achieve full self-understanding.12

Philosophy eventually supersedes art because it allows the spirit to move beyond sensuous representation into the realm of pure thought. In philosophy, the spirit achieves its final articulation as Idea, where it can grasp itself conceptually rather than through the symbolic or figurative means of art. Thus, while art captures the Zeitgeist of specific historical stages, philosophy provides the ultimate, conceptual clarity that represents the spirit knowing itself as spirit.13
