Carnes Lord, a scholar on Aristotle, has argued against the sufficiency of this view, however, noting the numerous cross-references between Jaeger's supposedly separate works and questioning the difference in tone that Jaeger saw between them. For example, Book IV explicitly notes the utility of examining actual regimes (Jaeger's "empirical" focus) in determining the best regime (Jaeger's "Platonic" focus). Instead, Lord suggests that the "Politics" is indeed a finished treatise, and that Books VII and VIII do belong in between Books III and IV; he attributes their current ordering to a merely mechanical transcription error.
