From a phenomenological perspective of game-space and horizon,this paper tries to make a deconstructive reading of Hegel's "two galleries",namely,"the gallery of opinions"and "the gallery of knowledge",which are mentioned in the introduction of Hegel's Lectures on the History of Philosophy.The reading shows that the Game-space or the ab-gruendiger Grund of the Hegelian concept of philosophical history lies in an originally differencing space that is keeping in absence,which is called by Edmund Husserl and Jacques Derrida "the gallery of Dresden".
