    Plato Plato Presentation Transcript

    • Plato & Socartes Dr. Mary Ann Clark
    • Introduction
      • The philosophies of Socrates, Plato and Aristotle form the foundation for all of Western philosophy and theology.
      • The answers they developed to life's eternal questions continued to influence our thinking today.
    • Questions to Consider
      • Can you know things beyond what you can perceive with your senses? How?
      • How do we recognize that something we've never seen before is a chair? table? tree?
      • What is Love? Goodness? Beauty? How do you recognize these virtues?
      • Can Love make you a better person?
      • How do you know something is Good? Is Good a universal value?
    • Life of Socrates
          • Lived 469-399 BCE
          • Spent his time in conversation and contemplation
          • Was a relentless questioner of his fellow citizens
          • Developer of the “Socratic Method” of questioning
          • Most of what we know comes via his pupil Plato
    • Life of Plato
      • Born about 428 BCE in Athens
      • Met Socrates about 409 BCE
      • Witnessed the trial and execution of Socrates in 399
      • Traveled widely through out the Mediterranean
      • Returned to Athens and founded the Academy in 387
      • Died 348 or 347 BCE in Athens
    • Plato’s Academy
      • The Academy is said by many to be the first European university. Its comprehensive curriculum included astronomy, biology, mathematics, political theory and philosophy.
      • It was closed almost 1000 years later (529 CE) by Emperor Justinian.
    • Symposium
      • “ Symposium ” was a Greek drinking party
      • All-male affair (the women were entertainers, young boys were servers)
      • Diners ate stretched out on couches large enough for two
      • Plato ’ s “ Symposium ” an analysis of “ Love ”
    • Love or “Eros”
      • Eros may more properly be translated as “ desire ”
      • Greeks also thought of Eros as a deity, the God of Love
      • Eros was also the overwhelming erotic passion
      • Eros was also the idea of desire
      • All of these ideas are represented in the discussion of Love
      • Watch carefully for when the meanings change
    • Problematic Terms
        • “ Lover ” & “ beloved ” both male in this context
        • Marriages were arranged, husband & wife were unlikely to be “ in love ” as we understand it (Romantic Love in the context of marriage doesn't appear in Western thought until the Romantic Era (1825-1900).
        • Marriage was for reproduction, the continuation of the family and by extension, the state.
        • Greek men spent their formative years in all-male society & formed deep attachments to each other
        • Notice that Plato spiritualizes “ Love”
    • Goals of Love
      • Not physical but philosophical
      • Physical or sexual contact degraded and wasteful forms of erotic expression
      • Goal of eros is “ real beauty”
      • Goal is knowledge of Beauty itself
    • Goals of Love
      • Because the true goal of er os is real beauty and real beauty is the Form of Beauty, what Plato calls Beauty Itself, er os finds its fulfillment only in Platonic philosophy.
    • Goals of Love
      • Unless it channels its power of love into "higher pursuits," which culminate in the knowledge of the Form of Beauty, er os is doomed to frustration.
    • Goals of Love
      • For this reason, Plato thinks that most people sadly squander the real power of love by limiting themselves to the mere pleasures of physical beauty.
    • Plato’s Epistomology
      • Epistomology is the study of knowledge.
      • For Plato the question becomes how do we know what we know? Plato watched his mentor Socrates tease out the understanding of an idea through his questions.
      • He came to believe that we all know everything already and only need to be reminded of what we know.
    • Plato’s Epistomology
      • Plato thought that before we were born we existed on another plane. We might call that spiritual plane 'heaven' but I don't want you to confuse his ideas with our ideas of heaven.
      • Our ideas of heaven come from a different cultural background.
    • Plato’s Epistomology (2)
      • The Forms (note capitalization) also exist in this otherworldly plane.
      • The Forms are the ideal, perfect, eternal and unchanging models of everything, every physical thing, every idea, everything that can exist.
      • We recognize something (a table for example) as what it is because we've had an encounter with the Form 'Table' before.
      • All physical tables (which can be very different from each other) share enough characteristics with the Form 'Table' that we recognize them as members of the class table.
    • Plato’s Epistemology (3)
      • Plato thought that we are able to recognize things and learn new ideas because we already know the Forms of those things.
      • I'm not really teaching you anything. Rather, according to Plato, I'm reminding you of what you already know. You already know not only tables and chairs, but abstract ideas like Love, Beauty and Goodness.
    • Plato’s Epistomology
      • Plato's not really concerned about tables and chairs but rather how do we recognize important ideas like Love and Beauty and Goodness.
      • He saw that by talking to people and asking them questions Socrates could get them to express some pretty sophisticated ideas.
      • How was that possible if they didn't already know the answers in some way?
    • Allegory of the Cave
      • The allegory of the cave is Plato's attempt to explain how we know what we know.
      • We are the prisoners who only see the shadows of images on the wall. We think those images are real. We think that they're really tables and chairs and trees, and all the abstract ideas. But they're actually two steps removed from the real thing.
      • When one person (the philosopher) is released, he can turn around and see that what he thought was real was only shadows of the objects the people were carrying along the wall in front of the fire.
      • In the case of the tree, you can imagine someone carrying a model of a Christmas tree.
      • These objects are more 'real' than the shadows but they are not the real objects either. They're just models of the real objects. A ceramic tree, for example.
      • When the philosopher climbs out of the cave, he can't look up because the light is too strong but he sees the reflection of the tree in the pond.
      • Although the image in the pond isn't really the tree either, it's closer because it's the image of the real tree rather than the shadow of a model (an image of an image).
      • When his eyes finally adjust he can look up and see the actual tree illuminated, not by a fire but by the Sun. Now he finally see a real tree, which is the Form all the images of the tree (the reflection, the model and the shadow) represent, albeit imperfectly.
