Aristotle’s Key Concepts: Nature, Society, Happiness, and More
Aristotle’s Core Philosophical Concepts
Aristotle’s philosophy encompasses a wide range of ideas. Here’s a breakdown of some of his key concepts:
Nature
For Aristotle, nature is the sensible world, the only reality that exists. He believed that this world, composed of material things, is imperfect and perishable. He referred to sensitive nature as containing individual beings, each composed of matter and form. Matter is the substrate, the material something is made of, while form determines the individual’s essence.
A key feature of nature is change. Individual beings change due to their structure of potentiality and actuality.
The Social Being (Politikon Zoon)
The politikon zoon, or social being, is one who lives in society. Aristotle believed that humans are inherently social and should be located within the state (polis) to achieve happiness and survival. He considered humans political animals, distinct from other living beings because of their capacity for language. Language allows humans to communicate and build societies. Aristotle prioritized the state over the individual because only the state can promote self-reliance.
Happiness (Eudaimonia)
Happiness, or eudaimonia, is the supreme good for human beings. It is complete in itself, the end goal of all human actions, and requires nothing else. While everyone desires happiness, the path to achieving it varies. Some believe it is reached through intellect (as Plato suggested), others through a pleasant life, and still others through political glory.
For Aristotle, goodness, happiness, virtue, or excellence lies in fulfilling one’s role effectively.
Substance
For Aristotle, the individual self is the substance. It is the subject that possesses properties. For example, Socrates is a substance, and we can attribute characteristics to him, such as being Athenian or being Plato’s teacher. Substance remains constant through accidental changes. Socrates remains Socrates even as his appearance changes over time. Substance is independent; it exists in itself, not in another. We must distinguish substance from attributes (such as being white, small, large, or intelligent, which are properties that people possess).
Potentiality and Actuality
Potentiality is the capacity to become something else, to acquire a new form. It is the ability to change. Aristotle contrasted potentiality with actuality. A seed has the potential to become a tree, while the tree is the seed’s actuality. A child has the potential to become a man, while the man is the child’s actuality. Being in potentiality is not nothingness; it is a future possibility.
Actuality is the present state of being. It encompasses the properties a thing or object possesses in the present moment.
Cause
Cause is the principle from which an individual being originates and what allows its existence. Aristotle identified four causes:
- Material Cause: The matter from which something is made.
- Formal Cause: The form or essence of an object.
- Efficient Cause: What produced the thing.
- Final Cause: The purpose or end for which the thing exists.
The material and formal causes are intrinsic, while the efficient and final causes are extrinsic.
