What does Georg Wilhelm Friedrich Hegel mean by absolute knowledge?

For Georg Wilhelm Friedrich Hegel, absolute knowledge represents the culmination of the human mind’s development, where consciousness transcends the limitations of subjective perspective to grasp the rational structure of reality itself.12

In his work The Phenomenology of Mind, Hegel traces the evolution of consciousness through various stages—such as sense certainty, perception, reason, and spirit—until it reaches "absolute knowing". At this final stage, the distinction between the knowing subject and the object of knowledge is eliminated. Consciousness achieves an understanding of the "Absolute"—the all-embracing totality of reality—as a conscious agent or Spirit that is realizing itself through history and culture.1234

By reaching this plane of unconditional truth, Hegel argued that reason could penetrate into the essences of things, overcoming the Kantian divide between phenomena (appearances) and noumena (things-in-themselves). Ultimately, absolute knowledge is the state in which the Spirit recognizes itself as Spirit, providing a unitary, rational account of the world, history, and human existence.214
