Determining Being-at-Work

I'm am going to intentionally keep this question as open ended as possible. Modern philosophers often criticize Aristotle for anthropomorphizing or imposing teleological constraints on nature. Chapter 9 of the metaphysics focuses on Being-at-work and potencies. To what extent do you grant Aristotle that A) being-at-work and potentiality aren't just imposed on nature and B) we can discover a thing's being-at-work/potentiality.
