The relationship between established phenomenological concepts, for example, by phenomenological psychopathology, and their applicability to the annihilation of self-consciousness in the final existential-ontological stage is roughly inverse. Phenomenology and phenomenological psychopathology especially offer descriptive and interpretative power regarding stages 1 and 2. The final third stage, however, requires both to include yet to go beyond the contemporary conceptual horizon of phenomenology to account for existential nihilism.
