Change, motion, and explanation › Using the questions without adopting every answer

For contemporary work, the four causes can be used as an explicitly modern set of questions. Suppose a team is explaining a failed product prototype. Material and component constraints differ from its organization, the process that produced it, and the purpose it was meant to serve. Distinguishing these questions may expose an explanation that answers only one of them. It does not prove that the artifact possesses a natural end in Aristotle's sense.

Potentiality offers another limited application. A learner's capacity is not the same as the practice through which it develops or the skill eventually achieved. That distinction can clarify a discussion of development without supplying a fixed ideal for every person's life. The Physics does not decide which ambitions someone ought to choose merely by describing change.

The work also teaches a habit of separating an intelligible question from a successful answer. Asking what makes a process continuous does not establish every ancient theory of motion. Asking what a structure is for does not establish that every useful result was intended. Aristotle's explanations deserve assessment at the level of their particular claims. That is how the investigation of change remains an investigation, rather than becoming a vocabulary that substitutes for one.
