1Mind-Body Problem
Question: How does the physical brain create thoughts, emotions, and consciousness?
Answer: No one knows how neurons firing in your brain produce the feeling of love or the idea of a poem.
Example: You feel pain when you touch fire—but how does that signal become "ouch" in your mind?
2Hard Problem of Consciousness
Question: Why do we have subjective experiences (feelings, sensations)?
Answer: Science can explain brain activity, but not why it feels like something to be you.
Example: A robot can detect red, but does it see red like you do?
3Free Will vs Determinism
Question: Are our choices truly free, or just reactions to past causes?
Answer: If everything is caused by something before it, maybe we don't choose freely.
Example: You choose tea—but was it your habit, mood, or brain chemistry deciding?
4Problem of Universals
Question: Do abstract ideas like "beauty" or "redness" exist independently?
Answer: Philosophers debate whether these are real or just mental labels.
Example: Is "red" a real thing, or just how our brain interprets light?
5Ship of Theseus
Question: If you replace every part of something, is it still the same thing?
Answer: Identity may depend on continuity, not parts.
Example: If you upgrade every part of your PC, is it still your original PC?
6Qualia
Question: What are the raw feels of experience—like the taste of mango?
Answer: Qualia are the building blocks of subjective experience, but science can't measure them.
Example: You can describe mango's taste, but no one can feel it like you do.
7Moral Luck
Question: Can someone be blamed for outcomes they didn't control?
Answer: Morality may depend on luck, not just intention.
Example: Two drunk drivers—one hits a child, one doesn't. Are both equally guilty?
8Infinite Regress
Question: Can explanations go on forever without a final answer?
Answer: If every reason needs another reason, we never reach the truth.
Example: Why is the sky blue? Because of light… but why light? And so on.
9Personal Identity
Question: What makes "you" the same person over time?
Answer: Memory, body, and personality all change—so what stays constant?
Example: If you forget everything, are you still you?
10Simulation Hypothesis
Question: Are we living in a computer simulation?
Answer: Some scientists say it's possible—if computers get advanced enough, they could simulate worlds.
Example: Like The Matrix—what if reality is just code?
11Brain in a Vat
Question: Could our experiences be artificially simulated?
Answer: If a brain were kept alive and stimulated, it might experience a virtual reality.
Example: Like dreaming vividly but never waking up—how would you know it's not real?
12Problem of Evil
Question: Why does suffering exist in a world with benevolent creators?
Answer: Philosophers struggle to reconcile perfect goodness with the existence of pain.
Example: Natural disasters claim innocent lives—why would a loving god allow this?
13Chinese Room Argument
Question: Can machines truly understand, or just simulate understanding?
Answer: Following rules to produce Chinese responses doesn't mean understanding Chinese.
Example: A person following a recipe in an unknown language doesn't understand the cuisine.
14Zeno's Paradoxes
Question: Can motion and change be logically impossible?
Answer: Infinite divisions of space and time seem to make movement paradoxical.
Example: To reach a wall, you must first cover half the distance, then half again—infinitely.
15Veil of Ignorance
Question: How would we design society if we didn't know our place in it?
Answer: Rawls argued we'd create fairer systems if unaware of our future status.
Example: Designing laws before knowing if you'll be rich or poor, able or disabled.
