1.1 What is Philosophy?
Philosophy is one of humanity's oldest intellectual pursuits. The word itself comes from the Greek words philos (love) and sophia (wisdom), meaning "love of wisdom."
Philosophy: The systematic study of fundamental questions about existence, knowledge, values, reason, mind, and language through rational argument and critical analysis.
Unlike other disciplines that focus on specific domains, philosophy asks the most basic questions:
- Metaphysics: What is the nature of reality? What exists?
- Epistemology: What can we know? How do we know it?
- Ethics: What should we do? What is good?
- Logic: What makes reasoning valid?
- Aesthetics: What is beauty? What is art?
Philosophy doesn't give us facts like science does. Instead, it teaches us how to think critically, examine assumptions, and construct sound arguments. These skills are valuable in every area of life.
1.2 Why Ancient Greece?
Around 600 BCE, something remarkable happened in the Greek world. Thinkers began asking questions about nature and seeking natural rather than supernatural explanations.
Before philosophy, people explained the world through myths. Why does the sun move across the sky? Because the god Helios drives his chariot. Why do seasons change? Because Persephone goes to the underworld.
The first philosophers asked: What if we could explain these things without invoking the gods? What if nature follows consistent, discoverable principles?
| Mythological Explanation | Philosophical/Natural Explanation |
|---|---|
| Zeus throws lightning bolts | Lightning is a natural electrical discharge |
| Poseidon causes earthquakes | Earthquakes result from movements in the earth |
| Gods determine your fate | Events follow natural causes |
Several factors made Greece fertile ground for this new way of thinking:
- Trade and travel: Greeks encountered different cultures and ideas
- Democracy: Debate and persuasion were valued skills
- Leisure class: Some had time to think beyond daily survival
- Writing: Ideas could be recorded and examined
What was the key shift that marked the birth of philosophy in ancient Greece?
1.3 The Pre-Socratics
The philosophers before Socrates are called "Pre-Socratics." They asked a fundamental question: What is the basic substance or principle underlying all of reality?
Thales of Miletus
- Everything is made of water
- Natural explanations for phenomena
- First philosopher
"Water is the principle of all things."
Thales proposed that water is the fundamental substance of everything. This seems naive today, but what matters is that he sought a natural explanation, not a mythological one.
Heraclitus
- Everything flows (panta rhei)
- Fire as the basic element
- Unity of opposites
"You cannot step into the same river twice."
Heraclitus focused on change. Reality is constantly in flux, like a river. The apparent stability we see is an illusion.
Parmenides
- Reality is unchanging
- Change is an illusion
- What is, is
"What is, is. What is not, is not."
Parmenides took the opposite view: change is impossible. If something exists, it cannot come from nothing or become nothing. Therefore, reality must be eternal, unchanging, and one.
Step into the river, then switch perspectives. Does the moving water make it a different river each time?
You have stepped in 1 time. Each time, the water has flowed on. For Heraclitus, this is a different river at every moment — "you cannot step into the same river twice." Reality is constant flux.
Reflect: which is more "real" — the flowing water, or the enduring form?
The debate between Heraclitus (everything changes) and Parmenides (nothing changes) set up one of philosophy's most enduring questions: How do we reconcile the appearance of change with the possibility of stable, knowable reality?
Which philosopher argued that reality is unchanging and that change is an illusion?
Module Summary
In this module, you learned:
- Philosophy means "love of wisdom" and examines fundamental questions
- Philosophy began in ancient Greece around 600 BCE
- The Pre-Socratics sought natural rather than mythological explanations
- Thales, Heraclitus, and Parmenides asked about the basic nature of reality
- The change vs. permanence debate shaped all later philosophy
Next up: In Module 2, you'll meet Socrates, the philosopher who changed everything by asking questions instead of giving answers.
