From Myth to Logos: A Transformation in Greek Thought

In the Greek world, a transformation occurred, shifting from religious and mythical explanations to rational ones. This is commonly called the Step from Myth to Logos.

The Pre-Socratic Philosophers

The natural philosophers, also called “physicists” by Aristotle, searched for the arkhe (origin or principle) of the world in nature. Key figures include:

  • Thales of Miletus: Believed the origin was water.
  • Anaximander: Proposed the arkhe was the “apeiron” (the indefinite or boundless), which has no form.
  • Anaximenes: Said the origin was air.

These were monistic philosophers, proposing a single element as the arkhe. In contrast, pluralistic philosophers proposed multiple origins:

  • Democritus: Proposed four elements.
  • Atomists: Believed the origin was in atoms.
  • Pythagoreans: Said that the origin was numbers.
  • Anaxagoras: Introduced “Nous” (mind or intelligence) as an ordering principle, influencing Plato’s Demiurge.

Plato’s Philosophy: Parmenides and Heraclitus

Plato was a follower of Parmenides but was also influenced by Heraclitus.

  • Parmenides maintained that only the “Being” exists, perfect and immutable.
  • Heraclitus argued that the essence of reality is the struggle of opposites; there is only change.

Both were committed to rational knowledge.

Plato’s Two Worlds

Reconciling Parmenides’ unchanging Being with Heraclitus’ concept of change, Plato proposed two realms:

  • The World of Ideas: Composed of perfect, immaterial, timeless, and unchanging Ideas, accessed through reason.
  • The Sensible World: An imperfect copy of the World of Ideas. It is material, temporal, mutable, and subject to change, perceived through sensory knowledge (doxa).

Plato explains this relationship through the figure of the Demiurge, who modeled the sensible world after the World of Ideas, using the four elements.

The World of Ideas is structured hierarchically, with the Idea of the Good at the apex and less perfect ideas at the base. It is governed by principles of unity (one world) and plurality (composed of different ideas).

Plato’s Epistemological Dualism

Plato proposes an epistemological dualism, with different levels of knowledge, as reflected in the allegory of the “Divided Line”:

  1. Rational Knowledge:
    • Noesis: The most perfect knowledge, capturing the World of Ideas through the soul. This relates to the theory of reminiscence, stating that humans are divided into body and soul.
    • Intermediate Knowledge: Less perfect, based on the material world but reaching towards the World of Ideas.
  2. Sensible Knowledge:
    • Belief: Deals with knowing the sensible world as it is.
    • Imagination: A vague understanding of the world, representing the world of the senses.
The Myth of the Cave

In the Myth of the Cave, Plato describes prisoners chained in a cave, only able to see shadows cast on the wall by a fire behind them. They mistake these shadows for reality, never having seen the true forms outside the cave. This illustrates the difference between the sensible world (shadows) and the World of Ideas (the true forms).
