For in every action what is primarily intended by the doer, whether he acts from natural necessity or out of free will, it is the disclosure of his own image. Hence it comes about that every doer, in so far as he does, takes delight in doing; since everything that is desires its own being, and since in action the being of the doer is somehow intensified, delight necessarily follows... Thus, nothing acts unless [by acting] it makes patent its latent self.
