[The world presents] the self-externalization through which spirit actualizes itself . . . manifesting pure nature outside itself as time, and its structure as space. Since the ultimate end of the self consists in knowing that which it is-- its substance-- completely, this knowing is a delving into itself in which it leaves behind its mere particular existence and gives itself over to recollection . . . Its transcended particular existence, however, is still retained; and this transformed existence-- which is the same existence as before, only reborn through knowledge-- is a new existence.
The realm of the spiritual forms, which in this way attains concrete existence, constitutes a succession, in which one form gives rise to another . . . The goal, which is absolute knowledge, or spirit knowing itself as spirit, is reached through recollection of these spritual forms [in philosophical logic], both as they are in themselves and as they bring about the organization of their existing spiritual domain [phenemology of the spirit].
Their preservation, as free existence appearing in the form of the contingent, is history organized systematically in concepts, however, it is the science of the structure of appearances. Both together, history comprehended in concepts, form the recollection and the totality of absolute spirit.
--G. W. F. Hegel
