(2) In the history of philosophy the different stages of the logical Idea assume the shape of successive systems, each based on a particular definition of the Absolute. As the logical Idea is seen to unfold itself in a process from the abstract to the concrete, so in the history of philosophy the earliest systems are the most abstract, and thus at the same time the poorest. The relation too of the earlier to the later; systems of philosophy is much like the relation of the corresponding stages of the logical Idea: in other words, the earlier are preserved in the later; but subordinated and submerged. This is the true meaning of a much misunderstood phenomenon in the history of philosophy--the refutation of one system by another, of an earlier by a later. Most commonly the refutation is taken in a purely negative sense to mean that the system refuted has ceased to count for anything, has been set aside and done for. Were it so, the history of philosophy would be of all studies most saddening, displaying, as it does, the refutation of every system which time has brought forth. Now, although it may be admitted that every philosophy has been refuted, it must be in an equal degree maintained, that no philosophy has been refuted, nay, or can be refuted. And that in two ways. For first, every philosophy that deserves the name always embodies the Idea: and secondly, every system represents one particular factor or particular stage in the evolution of the Idea. The refutation of a philosophy, therefore, only means that its barriers are crossed, and its special principle reduced to a factor in the completer principle that follows. Thus the history of philosophy, in its true meaning, deals not with a past, but with an eternal and veritable present: and, in its results, resembles not a museum of the aberrations of the human intellect, but a Pantheon of Godlike figures. These figures of Gods are the various stages of the Idea, as they come forward one after another in dialectical development. To the historian of philosophy it belongs to point out more precisely, how far the gradual evolution of his theme coincides with, or swerves from, the dialectical unfolding of the pure logical Idea. It is sufficient to mention here, that logic begins where the proper history of philosophy begins. Philosophy began in the Eleatic school, especially with Parmenides. Parmenides, who conceives the absolute as Being, says that 'Being alone is and Nothing is not.' Such was the true starting-point of philosophy, which is always knowledge by thought: and here for the first time we find pure thought seized and made an object to itself.
