Schelling’s positive philosophy:
For Hegel, the eventual reconciliation of “thought” and “being” requires a complete and determinate system, e.g. the Absolute Idea. As such, he writes in the Science of Logic:
But in the idea of absolute cognition the concept has become the idea’s own content. The idea is itself the pure concept that has itself for subject matter and which, in running itself as subject matter through the totality of its determinations, develops itself into the whole of its reality, into the system of the science, and concludes by apprehending this process of comprehending itself, thereby superseding (aufzuheben) its standing as content and subject matter and cognizing the concept of the science. (§843)
In this way, the Absolute Idea is “the sole subject matter and content of philosophy” and, furthermore, “[t]he Absolute Idea alone is being, imperishable life, self-knowing truth and is all truth” (ibid. §824). According to Hegel, the Absolute Idea is the proper domain of philosophy, and nothing more. If this is the case, and “Philosophy” is understood as that which is concerned with Knowledge of the Absolute Idea, then all that which falls under the category of “Philosophy” is most certainly complete post-Hegel.
