"...by determining the relation which a philosophical work professes to have to other treatises on the same subject, an extraneous interest is introduced, and obscurity is thrown over the point at issue in the knowledge of the truth. The more the ordinary mind takes the opposition between true and false to be fixed, the more is it accustomed to expect either agreement or contradiction with a given philosophical system, and only to see reason for the one or the other in any explanatory statement concerning such a system. It does not conceive the diversity of philosophical systems as the progressive evolution of truth; rather, it sees only contradiction in that variety."

(Hegel, Phenomenology of Spirit)
