Call it conceptual callisthenics (Latour), the creation of concepts (Deleuze), or the development of a wisdom tradition (Sloterdijk) -- either way, the point is that philosophy mustn't pursue its own ends. Such self-pursuit is, one could even say, unphilosophical.
Self-pursuit is scholasticism; is a dog chasing its own tail; is a serpent eating itself...
Such autogenesis becomes autoerotic.
