To enquire the essence of historical development, Hegel takes the way what he calls ”philosophical-history” method. Through this way, I argue, Hegel's theory in philosophy of history essentially presents two major parts. One of it is, in the first part of this paper, the central system of Hegel's speculative philosophy is connected inherently with his philosophy of history. The other side, in the second part of this paper, the core theory in philosophy of history is dogmatically established by the ideal of spirit in subjectivity and objectivity meaning. By considering Hegel's philosophy of history from these two different perspectives, the research of this paper can demonstrate the critical influence of spirit ideal and the metaphysics system in Hegel's philosophy of history.
