The Encyclopedia of the Philosophical Sciences is a systematic work by Georg Wilhelm Friedrich Hegel in which an abbreviated version of his earlier Science of Logic was followed by the articulation of the Philosophy of Nature and the Philosophy of Spirit (also translated as Philosophy of Mind). The work describes the pattern of the Idea as manifesting itself in dialectical reasoning.
