The Ancient Greek Philosophers: Aristotle

Aristotle was a pupil of Plato, the teacher of Alexander the Great, and he wrote extensively on many various subjects, including logic, biology, music and rhetoric. Aristotle’s work on logic was a great foundation for human logic, and the work he recorded was the work used by philosophers who lived thousands of years on, such as Immanuel Kant. Aristotle’s logic is based on the syllogism, which is, at its simplest, one conclusion from two premises:

P1 All men are mortal.

P2 Socrates is a man.

C Socrates is mortal.

This is deductive logic, and if one accepts both the premises, then one must accept the conclusion that follows. To therefore attack the conclusion, one must attack the premises. There is so much that one could potentially say about Aristotle, so I will mention only a couple of his key ideas.

Aristotle believed that everything has a nature and a ‘telos‘ (end or goal) to fulfil. His idea was that ‘essence precedes existence’-something’s nature is defined before it exists. He argued that, like all other beings, humans also have a nature and a telos. For Aristotle this was eudaimonia, or flourishing, and this is attained by using all one’s talents and becoming balanced through the golden mean, avoiding excess and deficiency. To attain this, we should enhance our practical reasoning as well as our intellect. ‘What is the meaning of life?’ Aristotle asked himself, to which he answered, ‘To do good and serve others.’

Aristotle had a certain idea of excellence, and it was that it is attained through training and habituation. Like all virtues, Aristotle believed that to become excellent took time, and required consistency and balance-we cannot hope to be something if we only act in that way rarely. Rather, we should act that way as much as we can, and through this repetition we will train ourselves to become what that virtue is.

The influence of Aristotle is magnanimous. He influenced many, including Thomas Aquinas, Martin Heidegger and Immanuel Kant. To the foundations of logic and to the influential ethical and political theory we owe Aristotle a great deal.
