Therefore pleasure is not a motion; for every motion requires time and implies an end ( e.g. the motion of building), and is complete when the desired result is produced⁠—either in the whole time therefore, or in this final moment of it. But during the progress of the work all the motions are incomplete, and specifically different from the whole motion and from each other; the fitting together of the stones is different from the fluting of the pillar, and both from the building of the temple. The building of the temple is complete; nothing more is required for the execution of the plan. But the building of the foundation and of the triglyph are incomplete; for each is the building of a part only. These motions, then, are specifically different from one another, and it is impossible to find a motion whose nature is complete at any moment⁠—it is complete, if at all, only in the whole time.
