Life’s Ultimate Questions “Plato” Christopher Ullman, Instructor Christian Life College
Student of Socrates (469-399 B.C.) • Socratic Method • A way through persistent questioning to eliminate the worst hypotheses by finding the contradictions • “I know that I know nothing.” • Constantly seeking wisdom in Athens • Philosophy’s most famous martyr
Plato (427 – 347 B.C.) • Plato and Aristotle seek to answer every major philosophical question • “Everything in philosophy after Plato and Aristotle is just commentary” • The death of Socrates when Plato was 28 was the turning point in his life • Plato’s influence can be detected in the history of Christian theology through the centuries
Touches on all of these areas Metaphysics “What is real?” Epistemology “How do we know what we say we know?” Ethics “What is a good life?” Aesthetics “What is beauty?” Politics “What is justice?” Plato’s Philosophy
What Plato Opposed • Hedonism • “Pleasure is the highest good” • Empiricism • “Sensed experience is the only sure source of knowledge” • Relativism • Ethical: “The right thing to do depends on ___________.” • Epistemological: “Truth depends on ___________.” • Materialism • “Matter/energy is all that there is”
What Plato Opposed • Mechanism • “All events are controlled by machine-like laws without purpose or design” • Atheism • “There are no gods” • Naturalism • “Nature is self-sufficient and self-explanatory”
Plato’s Dualism: Metaphysical Existence is of two types: • Particular things: always changing, never perfect, time-limited, mere material • The realm of Becoming and • Appearances • Forms: unchanging, perfect, eternal, nonmaterial • The realm of Being and • Reality
Plato’s Dualism: Epistemological Information comes from two sources: • Sensed experience • Unreliable because of • the deceivability of the senses and • the impermanence of physical things • It can never result in anything but Opinion • Reason • Reliable because • it focuses on apprehending the Forms • It alone results in Knowledge
Plato’s Dualism: Anthropological Humans are comprised of • Body • Soul
The ladder The circle The cave The ring The beast/lion/man The chariot Memory Keys to Plato’s Thought
The Ladder KNOWLEDGE Thoughts must pass some tests in order to climb the ladder of knowing • Error and sorrow result from letting a thought climb higher on the ladder than it should OPINION
The Ladder Opinion • Thoughts based only on particular sensed experiences should never be allowed to ascend higher than the lower rungs • Examples • Images, sounds, tastes, scents • The physical objects themselves OPINION
The Ladder KNOWLEDGE Thoughts of universals can climb the ladder • For example, the concepts • “Dog,” • “Movement,” and • “Hue” transcend the limits of a particular sensed experience • The concepts outlast the physical object • The concepts never change Knowledge of the Forms is the only real knowledge • Therefore, they point to the Forms
The Ladder KNOWLEDGE The middle rungs are accessible to thoughts based on reason unaided by the senses, like • Geometry • Logic The upper rung is accessible to a thought that is based on intuition, or immediate contact with the Forms • Justice • Balance
The Ladder Life viewed from the bottom rungs of the ladder appears • Out of focus • Unordered • Avalanched by trivia And is • Not representative of reality ? ? ? ?
! ! The Ladder ! ! ! Life viewed from the top rungs of the ladder is • In focus • Ordered • Meaningful And is • Representative of reality
The Circle • What is a circle? • Definition • Has anyone ever seen a circle? • Is there such a thing as a circle? • The Idea of Circle is totally real, even though there is no physical object that denotes it • Ideas (Forms) are really real in a way that physical objects can never be
The Cave • There are prisoners shackled in a cave, being deceived by flickering, fire-lit images on the wall. They think that those images are what is real.
One person escapes his shackles and cautiously climbs up and out of the cave Outside, he discovers what is actually real. All the objects are illuminated by a steady, non-flickering, brilliant light. The Cave
What would you do if you knew nobody was watching? Is it better to be moral, or to be immoral? The Ring
Which of these should rule us? The Beast/Lion/Man
The Chariot APPETITES REASON • In humans, there are three powers at work: • Appetites • Spirit • Reason Spirit
The Forms • Essence precedes existence • Essence is a necessary condition of existence • Without essence, there are no categories, since there are no attributes that make categorization possible • Each thing exists in at least one category • The Forms are known a priori, not a posteriori • The disembodied soul, in the interims between reincarnations, beholds the Forms in all their glory • Certain bodily experiences aid us in recollecting the Forms • The Craftsman took formless material and fashioned it into the world, using the Forms as patterns
Some of Plato’s Contributions to Theology • Creationism • The world is a handiwork of a mind • This World is Not our Home • The soul should be on a journey • There’s More to this Life • Than living and dying, more than just trying to make it through the day
