Philosophical Dualism in Hegel's Philosophy

The great German philosopher, Hegel established the magnificent foundation of his absolute Idealism, benefiting from Greek's Idealism, and criticizing and rejecting Kantian noumenon and based on the principle of identity of knowledge and being. He believed that dualism is the source of need to philosophy, and that to prevail up this dualism is the responsibility of philosophy. Hegel's Absolute Idealism, with this presupposition, ought to deduce all the being from pure thought or primal reason. But Hegel's philosophy, in undertaking the burden of this responsibility encountered problems such as ambiguous deduction of nature from logic, the absence of exact interpretation of existing probabilities in nature, the return of Kantian noumenon at the time of explaining the probable details of nature and Hegel's unsuccessful manner in "phenomenology of spirit" in undertaking the above mentioned responsibility.
