Plato’s Philosophy: An Introduction
ANNEX I. Introduction to Plato’s Philosophy
1. Sources of Plato’s Thought
Plato, a highly original philosopher second only to Aristotle, created the most important philosophical system of antiquity. His thought, while innovative, was influenced by earlier philosophers, offering new solutions to shared problems. Key figures include:
Socrates
Plato largely followed Socratic teachings. His philosophy of morality and politics stems from this influence: virtue is knowledge, and vice is ignorance. Both

Legal Freedom
A core characteristic of citizenship, legal freedom ensures individuals aren’t bound by laws without prior consent. It emphasizes acting autonomously while respecting others’ freedom. This freedom is shaped by laws, ensuring compatibility among individuals’ freedoms. Citizens should be co-legislators.

A hypothetical agreement where people transition from a natural, semi-wild state to a civil one. For Kant, it’s an obligation, enabling actions only possible within

Second Level of Certainty: “I Am”
Descartes argues for a certainty surpassing even mathematical truths, a certainty immune to deception by any malicious spirit. This is the undeniable certainty of one’s own existence.

This questioning is required by the first rule of his method, which requires

A Treatise of Human Nature
Philosopher David Hume, a contemporary of Newton and Adam Smith, authored A Treatise of Human Nature, later summarized in the Compendium. He proposed a new ‘science of man,’ aiming to explain human understanding through experience, particularly focusing on causality.
Critique of Causality
Hume’s critique of causality is central to his philosophy. As an empiricist, he believed complex ideas arise from simpler ones, tracing these back to sensory impressions. He argued that
