چکیده (انگلیسی): Among the thinkers of enlightenment age and thereafter, in no philosopher like Hegel there is so deep connection between foundations of his philosophy and concept of freedom. He sometimes suggests that his philosophy is not only the explaining of freedom, but also its ultimate fulfillment. Hegel begins from the concrete world and it is from this base that he discovers the public identity of man in the heart of society. To reach freedom, he proposes concrete morality, against kantian abstract morality. Hegel, after this procedure, reaches a kind of rationality that originates in the foundation of concrete morality. This rationality certainly is not of the kind of kantian pure reason, but is historical and cultural. The rationality of concrete morality develops and extends in the course of time and in procedure of history. In order to show this rationality in the hearts of social moralities, Hegel appeals to philosophy of history. In Hegel's view, the absolute freedom don't fulfill unless in a society in which institutions, costumes, laws, duties and values govern; because these are the only context in which abilities of freedom develop and remain permanent. The modern state, since contains all necessary institutions for fulfillment and appearance of freedom, is the best fulfillment of freedom in the history of world
