Lecture on Introduction to Plato and Western Philosophy

Introduction to Philosophy

  • Every philosopher is influenced by their circumstances, both personal and societal.
  • Plato is considered a fundamental figure in Western philosophy, originating in ancient Greece.
  • Early Greek philosophy transitioned from mythological explanations to logical reasoning.

Early Greek Philosophers

  1. Tales
    • First logical philosopher.
    • Contrived that the world is made up of water.
  2. Anaximander
    • Student of Tales.
    • Proposed the world is made up of an abstract, infinite substance that can take any shape.
  3. Pythagoras
    • Known for the Pythagorean theorem in mathematics.
    • Believed the fundamental element of the world is numbers.
  4. Heraclitus
    • Believed change is the only constant (e.g., "You can never step in the same river twice").
  5. Parmenides
    • Contrasted Heraclitus by believing in the permanence of the world. Reality is unchanging.

Socrates and Sophists

  • Sophists:
    • Claimed man is the measure of all things.
    • Believed in relativism: each person has their own truth.
  • Socrates:
    • Disagreed with the Sophists.
    • Introduced the dialectic method: learning through questioning.
    • Believed knowledge is virtue.
    • Executed for his beliefs; his method of questioning threatened the establishment.

Plato's Background and Theory

  1. Influences

    • Plato combined ideas from predecessors like Heraclitus, Parmenides, and Socrates.
  2. Theory of Ideas (Forms)

    • Two Worlds Dichotomy
      • Empirical World: World of Sensation, ever-changing, temporary, imperfect copies, perceived through senses.
      • Transcendental World: World of Ideas/Forms, perfect, permanent, eternal, contains universals (e.g., tableness, humanness).
    • Copy Theory: Empirical objects are imperfect copies of their perfect forms in the transcendental world.
    • Participation Theory: Objects in the empirical world participate in the essence of their perfect forms.
    • Reflection Theory: Objects in the empirical world are mere reflections of their perfect forms.
  3. Theory of Knowledge

    • Souls originally reside in the transcendental world of ideas, pure and with perfect knowledge.
    • Due to ignorance and desires, souls fall into the empirical world, forgetting their knowledge.
    • Knowledge is reminiscence: recollection of the innate knowledge within the soul.
    • The soul's journey: from ignorance to liberation through recollection of innate knowledge.
  4. Socratic Influence and Plato's Dialogues

    • Plato immortalized Socratic methods and ideas through his Dialogues where Socrates questions various interlocutors.

Key Takeaways

  • Western philosophy evolved from mythological to logical explanations of the world.
  • Plato built upon ideas of predecessors, establishing his theory of forms to resolve debates between change and permanence.
  • Knowledge, according to Plato, is innate and needs to be recollected for the soul to achieve liberation.
  • Plato's philosophical discussions influenced later Christian ideas of heaven and the world.

Conceptual Understandings

  • Understand the difference between empirical and transcendental worlds according to Plato.
  • Grasp the importance of innate knowledge and the dialectic method introduced by Socrates and furthered by Plato.
  • Recognize Plato's contribution to the idea of universals and perfection through his theories.

Application in Learning

  • Engaging in philosophical inquiry involves understanding and questioning concepts deeply.
  • Note-taking should incorporate hearing, seeing, and writing for better retention.
  • Learning should aim for long-term memory through frequent revisions and conceptual clarity.
