Aristotle’s Metaphysics: Matter, Form, Change, and Potentiality

Aristotle’s Metaphysics: Key Concepts

Metaphysics, according to Aristotle, is knowledge or wisdom that surpasses the knowledge acquired through our senses. Wisdom implies going beyond sensible experience, seeking the causes of things. It concerns itself with knowledge at the highest level of abstraction. This abstract knowledge isn’t about the universal and the particular, or the level of sensible things. True wisdom, or metaphysics, is the most abstract and accurate of all sciences.

A central problem in defining metaphysics is that it is the study of being, its principles, and its causes. Metaphysics, therefore, applies to being and its causes.

Matter and Form

Aristotle posits that nature never presents matter without shape or form without matter. Everything is a unity of form and matter, which together constitute substance. To differentiate, matter and form are considered separately. The distinction between one thing and another lies in what it is made of – the matter. Matter is so primitive that it eventually becomes something else. A substance without form is never found.

The Process of Change

Change is a fundamental aspect of experience. Some changes are natural, others are human-made. The four causes of change are:

  • What is the thing?
  • Of what is it made?
  • By whom was it made?
  • For what purpose was it made?

These questions provide explanations for change and serve as a model for understanding all things. These four questions define:

  • What is the thing? -> Formal Cause
  • Of what is it made? -> Material Cause
  • By whom was it made? -> Efficient Cause
  • For what purpose was it made? -> Final Cause

Potentiality and Actuality

All things exist with a dynamic power that drives them towards their end. Aristotle distinguishes between potentiality and actuality to explain change and development. If an acorn’s end is to become a tree, the acorn is potentially a tree. Once it grows and becomes a tree, it is actualized. Something in potentiality requires something in actuality to initiate change. The notion of the unmoved mover isn’t about creation, but about understanding something actual that precedes potentiality. This concept explains motion. Everything in nature tends to fulfill its goal: for the acorn, it is to become a tree. The unmoved mover is the eternal principle of movement.
