Pre-Socratic Philosophy and the Rise of Athenian Thought

The Pythagorean School (6th Century BC)

As a Pythagorean philosopher, I consider the structure of the cosmos to be reducible to geometrical figures and numerical expressions. To us, the mathematical structure of the world is the fundamental reality.

Heraclitus vs. Parmenides: Archetypal Worldviews

• Heraclitus: Known as 'The Dark,' he proposed that the world is in a state of perpetual flow. His arche is fire, representing constant struggle and movement between opposites.
• Parmenides: In his poem On Nature, he argues for the immutability of reality. He claims that change is merely a sensory illusion. True being is single, immutable, and eternal; it does not move, and it is accessible only through reason.

The Pluralists

Pluralists argued that existence does not arise from a single principle, but from different elements, where change is simply the result of their combinations.

Empedocles

He proposed four fundamental principles (water, fire, earth, and air). Natural things are governed by the combinations of these elements, driven by the forces of Love and Hate.

Anaxagoras

He suggested that there are many types of seeds or materials that are qualitatively equal. The predominance of one element over another depends on the intervention of a force he called Nous (Mind).

Atomists: Leucippus and Democritus

They proposed that the world is made of basic, invisible atoms that move randomly and freely within a vacuum.

Athens: Democracy and the Sophists

In the 7th century BC, the political system shifted from aristocracy to democracy. Through the reforms of Cleisthenes and Pericles, free citizens of Athens gained equal rights.

The Sophists

The Sophists focused on human affairs. They taught rhetoric—the capacity to use language to argue, persuade, and demonstrate multiple sides of any issue. Their philosophy was characterized by:

• Skepticism: The belief that absolute knowledge is unattainable.
• Relativism: The idea that reality is subjective to each person.
• Sensationalism: Knowledge is derived from the senses.
• Nominalism: Ideas are merely names.
• Nihilism: The belief that nothing can be truly known.

Socrates (470–399 BC)

Socrates did not write his own works; our knowledge of him comes from Xenophon, Plato, Aristophanes, and Aristotle. He rejected the skepticism and relativism of the Sophists, asserting that man can access universal knowledge. He was deeply concerned with the education of the youth and the pursuit of excellence. His primary tool was the Socratic Method, which utilized dialogue, irony, and contradiction to reach the truth.
