We progress by making explicit the oppositions contained in the fundamental synthesis, by uniting these opposites, analysing the new synthesis, and so on, until we reach an ultimate pair.
They were total opposites in many ways.
In the Philosophy of the Practical, but more especially in the work entitled What is living and what is dead of the Philosophy of Hegel Croce criticizes the erroneous treatment of the opposites, and shows that on the contrary every opposition has at bottom a distinction from which it arises, and that therefore the true unity is unity-distinction, which is development and, as such, opposition that is continuously surpassed and continually re-appearing to be again surpassed.
Apparently opposites did attract.
On Schelling's idealistic pantheism, or the hypothesis that there is nothing but one absolute reason identifying the opposites of subjectivity and objectivity, Hegel based his panlogism.
