How did Georg Wilhelm Friedrich Hegel differ from Immanuel Kant on the limits of human knowledge?

Georg Wilhelm Friedrich Hegel fundamentally disagreed with Immanuel Kant regarding the limits of human knowledge, viewing Kant’s restrictions as a "scandal to Reason".1

Their primary differences include:

• Phenomena vs. Essences: Kant argued that human knowledge is strictly limited to phenomena—the world as it appears to us through the senses. He maintained that the noumenon, or "thing-in-itself," is beyond human cognitive capacity. In contrast, Hegel sought to transcend this divide, arguing that reason is capable of "absolute knowledge" that can penetrate into the true essence of reality.12
• The Role of Reason: For Kant, the ideas of pure reason were merely "regulative ideals" that could not be verified by experience. Hegel, however, viewed the dialectical process of thought as a way to eliminate "otherness," allowing consciousness to reach a state of unconditional truth where the rational structure of reality is fully understood.13
• Subjectivity: Hegel criticized Kant’s philosophy for being overly dependent on the standpoint of the knowing subject, which he believed led to "subjectivism" and a devaluation of objective reality. While Kant focused on the limits of the human mind, Hegel aimed to reconcile ontology and epistemology to comprehend the universe as a systematic whole.13
