“What Am I — Qualia, Brahman, Neurons, or just Nothing?”
“Does experience contain qualities that cannot be captured by physical descriptions?”
Chat with SageQualia are the raw subjective properties of experience—the 'what-it-is-like-ness' of sensory states. This node explores the thought experiments that demonstrate why qualia cannot be reduced to physical facts.
Frank Jackson's thought experiment: Mary is a neuroscientist who has spent her life in a black-and-white room. She knows all the physical facts about color vision. When she steps outside and sees a red apple, does she learn something new? If she does, then physicalism is false, because there are facts about reality that are not physical facts.
Thomas Nagel argued that even if we had a complete physical map of a bat's sonar system, we could never know what it *feels* like to be a bat. Subjective experience is tied to a specific point of view, which objective science cannot capture by design.
Examines the logical structure of Jackson's argument, studying how the difference between knowing descriptions and knowing experience challenges physicalism. It highlights that direct experience is a unique form of knowledge.
