How Aristotle might approach Physics

We must begin by considering what is known to us. When we observe the world around us – the flight of an arrow, the fall of a stone, the growth of a plant – we see movement, change, and indeed, things that *do* something. This realm of happening, of that which comes into being and passes away, is what those who speak of ‘physics’ endeavor to understand.

It is evident that all these phenomena involve change. A thing is not always what it becomes. The acorn, which is but a small, dry thing, possesses the potentiality to become a great oak. This potentiality is actualized through a process, a movement from what it is to what it can be. We must therefore consider the principles of motion and change. What is the nature of this transition?

We can identify several kinds of change. There is change in respect of substance, as when a man becomes pale. There is change in respect of quality, quantity, or place. All these changes require a substratum, a matter, that undergoes the alteration. But mere matter is not sufficient. For change to occur, there must be something that brings it about – an efficient cause – and a form, an essence, that the thing is becoming. The oak is not just wood and sap; it is the *form* of oak, actualized from the acorn.

Furthermore, we must consider the final cause. Why does the acorn strive to become an oak? Because its nature, its *telos*, directs it towards this end. The final cause is the purpose, the good, for which a thing exists and acts. Thus, the study of physics is not merely an account of how things move, but of why they move, of the inherent principles that guide them towards their proper fulfillment. It is an inquiry into the fundamental principles of nature, understood through observation and logical reasoning, seeking to grasp the…
