<div style="background-color: #4B0082; color: #FFFFFF; padding: 20px; border-radius: 8px; margin-bottom: 15px;"> {{BloomIntro}} The Hard Problem of Consciousness is the "Study of the Deepest Mystery"βthe investigation of the "Philosophical and Scientific Problem" (~1994βPresent) that "Asks" "Why" and "How" "Physical Processes" in the "Brain" (see Article 207) "Give Rise" to "Subjective Experience" (Qualia): the "Felt Sense" of "Being." While "Neuroscience" (see Article 207) "Maps" "Neural Correlates of Consciousness" (NCCs) and "AI" (see Article 08) "Simulates" "Cognition," **The Hard Problem** "Asks" "Why" there is "Something it is Like" to be a "Bat," a "Human," or an "AI." From "Qualia" and "Phenomenal Consciousness" to "Philosophical Zombies" and "Panpsychism," this field explores the "Final Frontier of Science." It is the science of "Being," explaining why "The Brain" "Seeing Red" and "The Experience of Seeing Red" are **"Two Completely Different Things."** </div> __TOC__ <div style="background-color: #000080; color: #FFFFFF; padding: 20px; border-radius: 8px; margin-bottom: 15px;"> == <span style="color: #FFFFFF;">Remembering</span> == * '''The Hard Problem''' β (David Chalmers, 1995). The "Question": "Why" do "Physical Processes" in the "Brain" "Produce" "Subjective Experience" (Consciousness)? * '''Qualia''' β The "Intrinsic" and "Subjective" "Properties" of "Experience" (The 'Redness' of Red, The 'Pain' of Pain). * '''Phenomenal Consciousness''' β The "What-It-Is-Like" "Aspect" of "Experience" (Nagel, 1974). * '''Philosophical Zombie''' β A "Hypothetical Being" "Physically Identical" to a "Human" but "With" "No Subjective Experience" (Lights On, Nobody Home). * '''The Easy Problems''' β (Chalmers). "The Set" of "Neuroscience Tasks" (Attention, Memory, Behavior Integration) which "Do Not" "Require" "Explaining" "Qualia." * '''Neural Correlates of Consciousness''' (NCC) β (See Article 207). The "Specific Brain States" that "Correspond" to "Specific Experiences." But "Correlation" is "Not" "Causation." * '''Panpsychism''' β (See Article 713). The "View" that "Consciousness" or "Proto-Consciousness" is a "Fundamental Property" of "All Matter" (not just Brains). * '''Integrated Information Theory''' (IIT) β (Giulio Tononi). "Consciousness" is "Identical" to **"Phi"** (Ξ¦), a "Mathematical Measure" of "Integrated Information." * '''Global Workspace Theory''' (GWT) β (Baars / Dehaene). "Consciousness" "Occurs" when "Information" is "Broadcast" "Widely" through a **"Global Neural Workspace."** * '''The Explanatory Gap''' β (Joseph Levine). The "Logical Space" between "Physical Facts" about the "Brain" and "Facts" about "Consciousness" that "Science" "Cannot" "Bridge" with "Classical Methods." </div> <div style="background-color: #006400; color: #FFFFFF; padding: 20px; border-radius: 8px; margin-bottom: 15px;"> == <span style="color: #FFFFFF;">Understanding</span> == The Hard Problem is understood through '''Correlation''' and '''Causation'''. '''1. The "Easy/Hard" Divide (Taxonomy)''': "Not all mysteries are equal." * (See Article 207). We "Can" "Explain" "Attention," "Memory," and "Decision Making" "Physically." * These are **"Easy Problems"** β "Hard" to "Solve" but "Addressable" by "Science." * But we "Cannot Explain" **"Why"** "Neural Firing" "Feels" like "Anything" at "All." * "That" is the **"Hard Problem."** '''2. The "Inverted Qualia" Thought Experiment (Subjectivity)''': "Are you seeing MY red?" * When "You" "See" a "Stop Sign," your "Brain" "Processes" "the 650nm Wavelength." * But "What if" your "Internal Experience" of "Red" is "What I" "Call" **"Green"**? * We "Can" "Never" "Compare" "Subjective Experiences" "Directly." * "Consciousness" is **"Private."** '''3. The "Collapse" of Physicalism (Philosophy)''': "Can Science Explain Everything?" * (See Article 111). **Physicalism** "Claims" "Everything" is "Physical." * But "If" there are "Facts" about "Consciousness" (Qualia) that "Are Not" "Reducible" to "Physical Facts," then "Physicalism" is **"Incomplete."** * **The Hard Problem** is "The Test" of **"Scientific Ambition."** * "Consciousness" is **"The Measurement Problem."** '''The 'Nagel' Paper (1974)'''': (Thomas Nagel. "What is it Like to Be a Bat?"). A "Famous" "Argument" that "Even If" we "Knew" "Everything" about "Bat Brains," we "Would Never Know" **"What It Is Like"** to "Echolocate." It proved that "Subjective Experience" "Resists" "Third-Person" "Scientific Description." </div> <div style="background-color: #8B0000; color: #FFFFFF; padding: 20px; border-radius: 8px; margin-bottom: 15px;"> == <span style="color: #FFFFFF;">Applying</span> == '''Modeling 'The Consciousness Gap' (Calculating 'Explanatory Completeness' of Neural Models):''' <syntaxhighlight lang="python"> def evaluate_consciousness_model(explains_behavior, explains_reports, explains_qualia): """ Shows the 'Gap' between neural science and consciousness.
