3. What is Philosophy?  The term philosophy is a compound from the Greek words philo (love) and sophia (wisdom). It is best defined as the love of exercising one’s curiosity and intelligence.  Pythagoras (ca. 530 BCE) was the first to call himself a philosopher. Three classes of people at the games: Athletes- skilled seekers of fame; merchants- shrewd seekers of wealth; spectators- contemplative seekers of truth. For Pythagoras, rational reflection on abstract mathematical concepts purifies the soul by freeing it from attachment to bodily desires.

4. Philosophy’s Four Main Areas  Metaphysics: Examines the nature of reality. What is real? Does God exist? What is the self? Are we free?  Logic: Examines reasoning. How can we make reliable inferences?  Epistemology: Examines the concept of knowledge. What can we know and how do we know what we know?  Ethics: Examines the concepts of right and wrong.

Reflection improves practice.  Thinking about what you are doing, why you are doing it, and how you could do it differently make you better at what you do.  Theory affects practice, bad theories lead to bad practices. E.g.. Karma, samsara, spirits, heaven, egoism.

7. Personal Freedom  Only by subjecting the values and beliefs of our culture to critical scrutiny can we avoid being duped by persuasive propagandists who have an interest in manipulating us. To be truly autonomous and self determined we must learn to think critically, to question what we hear and ask for evidence.  For a better society. True democracy requires citizens who can contemplate the common good without being duped by groups with a religious or political agenda. Only careful, critical thinkers can evaluate social policy proposals from an objective and impartial perspective.

A clear, articulate, rational system of ideas.  Dialectical method- critical analysis of traditional beliefs.  Rational search for unchanging reality.  To know a things reality is to know the end or purpose it serves. To know human nature is to grasp the ideal that human nature strives to realize.  Discovering this ideal shows one how to live a life of fulfillment.

10. Origins of Philosophy  A paradigm shift in ancient Greece- from supernatural to natural explanations of the universe.  Supernaturalists rely on divination and inspiration to discover divine motives. What is Zeus thinking and how can we influence him? Claims are supported by intuition, shared subjective experience, and appeals to authoritative traditions. Naturalists rely on evidence and reasoning; claims that are open to criticism and investigation on the basis of consistency and empirical evidence.

11. The Sophists  As belief in the old religious myths waned, and a new class or merchants arose, a group of philosophers emerged teaching oratory skill and debate. For a fee one could learn to win friends and influence people. These enlightened men, who were liberated from superstition and ignorance, would teach their customers how to acquire wealth, fame, and honor.  Man is the measure of all things. Protagoras  When Zeus is uncrowned, chaos succeeds to his place, and chaos rules. Aristophanes
