Thanks for your input, the synthesis of spirit and matter is described in the "Encyclopaedia of the Philosophical Sciences" (Enzyklopädie der philosophischen Wissenschaften im Grundrisse), unfortunetly I can't find my original notes so I can't tell you the specific passage.
I would say that Hegel is definetly dualistical and he puts the mind above matter. When he describes god as the world spirit and god is above everything else, then you can conclude that there is a hierarchy where the spirit is above the matter. The way I understand the synthesis of spirit and matter is that humans are in one way spirit but unlike god they are also matter but not in a way that there is a unity of the mind and the body, they are still somewhat independent.

I am in no way an expert on this topic so it is not unlikely that I misunderstood or simplified some aspects, if you wrote your master thesis on the Science of Logic you know much more about this than me, so I wouldn't take me as a reference.
