Aristotle’s Philosophy

Introduction

Aristotle was a Greek philosopher and polymath during the Classical period in Ancient Greece. His writings cover many subjects including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theater, music, rhetoric, psychology, linguistics, politics and government. He was a student of Plato and is considered one of the most influential thinkers in Western history.

Separation Between Aristotle and Plato

  1. Aristotle did not accept Plato’s ontological dualism. He believed there is only one reality, the physical world.
  2. Aristotle emphasized the importance of the senses and experience in acquiring knowledge, something Plato downplayed.
  3. Aristotle believed there is a necessary connection between theoretical and practical philosophy, unlike Plato.

Plato’s Legacy on Aristotle

  1. Aristotle adopted Plato’s concept of a separate realm of Forms, although he modified it significantly.
  2. Aristotle’s teleological view of the universe, where everything has a purpose, was influenced by Plato.
  3. Aristotle’s belief in the immortality of the soul was influenced by Plato.
  4. Aristotle’s emphasis on education and the role of the philosopher in society was influenced by Plato.
  5. Aristotle’s view that contemplation is the highest virtue, directly connected with knowledge, was influenced by Plato.

Types of Knowledge

  1. Technical Knowledge: Learned through a set of rules, such as medicine.
  2. Practical Knowledge: Related to human behavior. Includes ethics, politics, and economics.
  3. Theoretical Knowledge: Scientific knowledge that seeks to answer three questions: what (definition), how (origin), and why (purpose).

Metaphysics

Metaphysics is the science of first principles and causes. It does not rely on the senses but requires reason.

Reality According to Aristotle

Aristotle believed that physical substances are composed of matter (hyle) and form (morphe). Matter is the underlying substrate, while form gives the object its characteristics and differentiates it from other things. This theory is called hylomorphism.

Theory of Causes

  1. Material Cause: What something is made of.
  2. Formal Cause: The shape or structure of something.
  3. Efficient Cause: What brings something into being.
  4. Final Cause: The purpose or goal of something.

Aristotle’s Life

After Plato’s death, Aristotle left Athens and became the tutor of Alexander the Great. He later returned to Athens and founded his own school, the Lyceum. The Lyceum focused on the study of the natural world, and students had more autonomy than in Plato’s Academy. After Alexander’s death, Aristotle was accused of impiety and fled to Euboea, where he died a year later.

Works of the Lyceum

Exoteric Works

  • Fragments of dialogues, including “On the Soul,” written in his youth and showing Platonic influence.
  • “On Philosophy,” written in Assos, criticizing Plato’s Theory of Forms.

Esoteric Works

  • Lecture notes on various subjects, more precise and less literary than Plato’s dialogues.
  • The ordering of these notes was lost for a long time and was eventually done by Andronicus of Rhodes.

Notes on Logic

Aristotle developed the field of logic, which he saw as a method of analysis. He defined logic as the “organon” or instrument of science. Aristotle is considered the father of logic.

Notes on Natural Sciences

Aristotle made significant contributions to biology, including developing many important concepts. He also wrote on astronomy and physics, covering a wide range of topics related to the natural world.

Notes on Ethics and Politics

Aristotle’s Nicomachean Ethics is a major work in ethical theory. He also wrote on politics, exploring the nature of the state and the good life for citizens.
