Lesson 1: Subjectivity
Graduate Philosophy Series
Seminar Objectives
Define the "Explanatory Gap" as presented by Thomas Nagel.
Distinguish between objective physical facts and subjective points of view.
Evaluate the claim that reductionism necessarily fails for phenomenal consciousness.
The "Bat" Hook
"Can you ever truly know what it feels like to use echolocation, no matter how much you study the neurology of a bat?"
Part 1: The Ontological Status of Subjectivity
Nagel argues that an organism has conscious mental states if and only if there is something that it is like to be that organism.
Key Question 1
Why does Nagel choose a bat rather than a rock or a person? How does this choice illustrate the limits of empathy vs. the limits of knowledge?
Key Question 2
If we describe a bat's sonar system in purely neuro-functional terms, what exactly is left out? Is the "missing piece" a physical fact or something else?
Part 2: The Failure of Reductionism
"If the subjective character of experience is fully comprehensible only from one point of view, then any move toward greater objectivity—toward a global viewpoint—takes us further away from the real nature of the phenomenon."
A
The Direction of Objectivity: In physics, moving from a human perspective to an objective one (e.g., describing lightning as electrical discharge) makes us understand it better. Why does Nagel think this fails for consciousness?
B
The Conceptual Problem: Nagel admits he isn't saying physicalism is false, but that we don't have a conception of how it could be true. Discuss the distinction between "falsehood" and "unintelligibility."

Exercise 1: The Echolocation thought Experiment
Consider a complete neuroscientific map of a bat's brain as it perceives a moth via echolocation. List three components of this map that are objective, and then describe the subjective residual that Nagel argues cannot be captured by the map.
Objective Facts (Neurology/Physics)
Subjective Residual (The "What-It-Is-Like")
Exercise 2: Analyzing the "Objective" Drift
Explain Nagel's paradox: Why does the standard scientific method of "moving toward objectivity" actually move us away from understanding the essence of consciousness?
Reflective Synthesis
Nagel concludes that we may never have a language to describe the subjective in objective terms. Do you agree that this is a permanent epistemic limit or just a current technological hurdle?

What Is It Like?
"An organism has conscious mental states if and only if there is something that it is like to be that organism."
— Thomas Nagel (1974)
The Problem of the Bat
1
Bats perceive the world through sonar / echolocation.
2
This is an experience fundamentally different from our visual/auditory modalities.
The Core Question
Can we ever truly grasp the internal character of this experience through objective neurobiology?
The Explanatory Gap
Objective Facts
Firing rates, neuro-transmitter levels, functional architectures. Accessible from any viewpoint.
Subjective Facts
The "qualitative" feel. Only accessible from the viewpoint of the organism.
The Gap
There is no current way to translate the physical into the phenomenal. Physicalism explains the function, but not the feeling.
Seminar Discussion
Is subjectivity a permanent barrier to a complete physical description of the universe?
"Every objective move takes us further away from the phenomenon we are trying to explain."
Qualia Argument Map Worksheet The Knowledge Argument
Analytical Case Study | Frank Jackson
Lesson 2: Qualia
Graduate Philosophy Series
The Case of Black-and-White Mary
"Mary is a brilliant scientist who is, for whatever reason, forced to investigate the world from a black and white room via a black and white television monitor. She specializes in the neurophysiology of vision and acquires all the physical information there is to obtain about what goes on when we see ripe tomatoes... what happens when Mary is released from her black and white room? Does she learn anything?"
I. Formal Reconstruction
Reconstruct Jackson's argument in a valid syllogistic form. Use the workspace below.
Premise 1:
Premise 2:
Premise 3:
Conclusion:
Objection A: Ability
"Mary doesn't learn a new fact; she simply acquires a new ability (know-how vs. know-that)."
Student Critique of Ability Hypothesis:
Objection B: Old Fact
"She learns an old physical fact via a new 'mode of presentation' or phenomenal concept."
Student Critique of New Mode Hypothesis:
Qualia & Semantic Information
Thought Experiment Extension: Fred and the Tomatoes
Jackson also mentions Fred, who sees a color (let's call it red*) that no one else can see. Even with a complete physical description of Fred's optical system, we still don't know what red* looks like.
Reflection: Epistemic vs. Ontological Gaps
Does the fact that Mary learns something epistemically (knowledge-wise) prove that there is an ontological (real-world) difference between physical facts and phenomenal ones?
KEY TERM
Qualia
The internal and subjective component of sense perceptions, arising from stimulation of the senses by phenomena.
DISCUSSION PROMPT
If physicalism is true, why is there a "feel" at all? Why couldn't we be just like Mary inside her room—information-rich but experience-poor?
UNIVERSITY OF MIND | PHI-502: ADVANCED PHILOSOPHY OF CONSCIOUSNESS
Knowledge Argument Slides Presentation Lesson 02: The Knowledge Argument
Mary's Room
Investigating the limits of physical information through Frank Jackson's 1982 masterpiece.
The Setup
Mary is confined to a black-and-white environment.
She learns every physical fact about color vision and neurophysiology.
She is finally released and sees a red rose.
?
The Intuition Pump
"It seems just obvious that she learns something new about the world and our visual experience of it. But she had all the physical information. Ergo, there is more to have than that, and Physicalism is false."
Epistemic vs Ontological
1. Information
Mary knows all the physical information about color vision.
2. The Discovery
Mary learns something new (what it is like to see red) upon release.
3. Conclusion
Therefore, not all information is physical information.
Does a gap in knowledge entail a gap in reality?
The Physicalist Fightback
The Ability Hypothesis
Mary doesn't learn facts (propositional knowledge). She gains abilities: to recognize, imagine, and remember.
Old Fact, New Mode
She already knew the physical fact. She just gained a phenomenal concept of it—a new way of thinking about the same reality.
Zombie Argument Analysis Worksheet The Zombie Argument
Metaphysical Analysis | David Chalmers
Lesson 3: Conceivability
Graduate Philosophy Series
The Philosophical Zombie
A P-Zombie is a being that is physically and behaviorally identical to a human being, but which lacks conscious experience, qualia, or sentience.
"The lights are on, but nobody's home."
The Modal Claim
If they are conceivability, they are possible. If they are possible, physicalism is false.
I. Conceivability Matrix
Analyze the logic of the argument by completing the missing logical steps below.
1
Conceivability
P-Zombies are conceptually coherent; there is no internal contradiction in their definition.
2
Bridge Premise (Modal Logic):
3
Metaphysical Possibility
Therefore, a world with p-zombies is metaphysically possible.
4
Final Conclusion regarding Physicalism:
II. Critical Challenge: Logical vs. Nomological
Physicalists often argue that p-zombies are logically possible but nomologically impossible (impossible given our laws of nature). Why does Chalmers believe that logical possibility alone is enough to sink Physicalism?
The Hard Problem of Consciousness
The "Easy" Problems
• Ability to discriminate stimuli
• Integration of information by a system
• Internal access to mental states
• Focus of attention
• Deliberate control of behavior
Explainable via functional mechanisms.
The "Hard" Problem
"Why is it that when our cognitive systems engage in visual and auditory information-processing, we have visual or auditory experience: the quality of deep blue, the sensation of middle C?"
Resistant to functional explanation.
Synthesis: Conceivability Lab
Consider the concept of "Water without H₂O". Is this as conceivable as "Brains without Consciousness"? If not, what makes the latter unique in philosophy?

Zombie Slides Presentation Lesson 03: Conceivability
Zombies
From Conceivability to Metaphysical Possibility: David Chalmers' challenge to Materialism.
The Philosophical Zombie
Physically Identical
Exact atomic replica of a conscious person. Obeys every physical law.
Behaviorally Identical
Speaks, screams, and acts just like us. Passes any Turing Test.
The Difference
Nothing.
...on the inside.
"There is no 'what it is like' to be a p-zombie."
The Syllogism
P1
P-Zombies are conceivable. (There is no logical contradiction in the idea.)
P2
Conceivability implies metaphysical possibility.
P3
P-Zombies are metaphysically possible.
C
Physicalism is false.
Can we separate the Physical from the Phenomenal?
Physicalists argue that consciousness is metaphysically necessary for certain brain states—just like H₂O is necessary for water.
The Counter-Point
"We can conceive of a world with all our physical laws but no consciousness. We cannot conceive of a world with all H₂O's properties but no water. The link is different."
Are you sure p-zombies are truly conceivable?
Does conceivability always lead to possibility?
What does this tell us about the 'Hard Problem'?
Eliminativism Illusion Notebook Worksheet The Illusionist's Notebook
Radical Materialism & Eliminativism
Lesson 4: Eliminativism
Graduate Philosophy Series
Quining Qualia
Daniel Dennett argues that the concept of "qualia" is so confused and laden with contradictory properties that we should simply "quine" it—eliminate it from our scientific and philosophical vocabulary.
I. The User-Illusion Hypothesis
Dennett suggests consciousness is a "user-illusion" created by the brain's "Virtual Machine." Respond to the following analogies:
The Desktop Metaphor
You see an "icon" of a folder on a screen. The folder doesn't actually exist as a physical object inside the CPU; it's an illusion to help you interact with the system.
Student Application to Consciousness:
The Magic Show
A magician makes a woman "vanish." The vanishing is an event that happens to the audience's perception, not a physical reality. Qualia are the "tricks."
Student Application to Consciousness:
II. Deconstructing Introspection
Eliminativists argue that our "internal access" is highly unreliable. Provide two examples from cognitive science (e.g., change blindness, confabulation) that support the idea that our certainty about our experiences is misplaced.
Case 1:
Case 2:
The Death of Folk Psychology
The Churchland Stance
"Our common-sense conception of psychological phenomena constitutes a radically false theory... that is destined to be replaced by a completed neuroscience."
Exercise: Conceptual Replacement
Consider the history of science: We replaced "Phlogiston" with "Oxygen" and "Demonic Possession" with "Neurochemistry." Predict how our vocabulary for pain or joy might change in an eliminative future.
The Ultimate Critique
Is the eliminativist's position self-refuting? If there is no such thing as "belief," how can they "believe" that eliminativism is true?
Unit 4: Radical Materialism Faculty of Philosophy
Eliminativism Illusion Slides Presentation Lesson 04: Illusionism
Quining Qualia
What if consciousness is not a problem to be solved, but a conceptual confusion to be eliminated?
The Death of the Cartesian Theater
Eliminativism denies the existence of the "Hard Problem" by denying the existence of its subject: Qualia.
"There is no 'secret chamber' where everything comes together for a witness. Consciousness is a distributed process of 'Multiple Drafts'."
Eliminative Materialism
Folk psychological concepts (belief, desire, pain) are false theories, like "caloric" or "phlogiston."
Illusionism
We seem to have qualia, but this "seeming" is just a functional state of the brain misrepresenting itself.
The User-Illusion
The Interface
Just as a computer desktop hides the complexity of binary, consciousness hides the complexity of neurons.
The Magic Trick
Consciousness is like a stage trick. We are amazed by the "result" but ignore the hidden "mechanism."
Multiple Drafts
Information is processed in parallel. There is no central "Me" who experiences the final cut.
The Great Critique
"To say that consciousness is an illusion is to admit that an illusion is occurring—and illusions are themselves conscious experiences."
How do the Eliminativists respond?
Panpsychism Synthesis Rubric Worksheet Mind in Matter
Alternative Ontologies: Panpsychism & IIT
Lesson 5: Synthesis
Graduate Philosophy Series
Galen Strawson's Panpsychism
Strawson argues that if you are a "realist" about consciousness and a "realist" about physicalism, you must conclude that matter is inherently experiential.
Core Dilemma: The Combination Problem
Integrated Information Theory (IIT)
Giulio Tononi proposes that consciousness is a fundamental property of systems with high "integrated information" (\(\Phi\)).
Core Metric: Phi (\(\Phi\))
I. The Combination Problem
If subatomic particles have tiny "proto-conscious" states, how do they combine to form the unified, complex "Me" that I experience? Explain the challenge below.
II. IIT Axioms & Postulates
IIT starts from phenomenology (what we know about experience) and moves to postulates (how a system must be built). Define the following concepts:
Integration (Exclusion):
Differentiation (Information):
Unit Capstone: The Explanatory Defense
Final Objective
Choose a stance (Dualism, Physicalism, Eliminativism, or Panpsychism) and write a 1-page defense. Your defense must specifically address the Explanatory Gap.

Mind in Matter
If consciousness can't be reduced or eliminated, must it be fundamental?
Panpsychism
The view that mentality is fundamental and ubiquitous in the natural world.
Avoids the "Explanatory Gap" by making mind the baseline.
Matter isn't "dead"—it has an intrinsic experiential nature.
Galen Strawson
"Real physicalism must be panpsychism... because we know that conscious experience is a physical property, and it cannot emerge from non-conscious matter."
Integrated Information Theory (\(\Phi\))
Differentiation
The system must have a massive number of possible states (information).
Integration
The states must be unified—the system is more than the sum of its parts.
\(\Phi\)
The Metric
Consciousness is a mathematical property of systems, not just biological brains.
Where do you stand?
Dualism
Mind is non-physical.
Physicalism
Mind is brain activity.
Eliminativism
Mind is an illusion.
Panpsychism
Mind is everywhere.
