There is due now the total reorganisation into something new. As Marcuse remarks in Reason and Revolution , the category of Actuality means merciless struggle. I have to leave it to you to work out with Hegel how a stage like Actuality expresses itself in Substance, then in Causality where, contrary to Understanding which perpetually sees cause here and effect there, Hegel sees cause as measurable only by effect. This cause is that effect. But that effect is another cause.
Effect is incited into action by cause.
But cause too is incited by effect. You cannot separate them. The opposing units are jammed too tight. From causality, the step is easy to action and reaction, what Hegel calls Reciprocity. It is a more intensive stage of Cause and Effect.
