Understanding Consciousness and Identity
Keep three questions distinct: what makes an experience conscious, how mental content gets its meaning, and what makes someone persist over time.
Learning objectives
- Distinguish qualitative experience from functional performance.
- Compare psychological, bodily, and historical criteria of identity.
- Recognize the gap between conceivability and possibility.
Recommended sequence
- Ship of Theseus — Begin with persistence in a nonhuman object.
- Teletransporter — Apply persistence criteria to a person.
- Fission and Personal Identity — Test whether numerical identity can branch.
- Swampman — Consider whether causal history matters to meaning.
- Chinese Room — Test a claim about syntax and understanding.
- Mary’s Room: The Knowledge Argument — Identify the alleged gap in physical knowledge.
- Philosophical Zombies — Ask what conceivability can establish.
- Inverted Spectrum — Look for assumptions about observable differences.
- What Is It Like to Be a Bat? — Ask whether a perspective can be captured by description.
Read each article’s scenario first, write an initial answer, and then read the interpretations and sources. Spend as long as useful; there is no required schedule.
Reflection questions
- Would a perfect behavioral duplicate settle all three opening questions?
- Can you reject one thought experiment’s conclusion while keeping its scenario?
Final synthesis activity
Make a table with columns for bodily continuity, psychological continuity, functional organization, and causal history. Explain which criterion each of four cases challenges. End with a provisional theory and a counterexample you still cannot answer.
