Editing Knowledge argument (section)

== Background ==
Jackson says there are quite a few similar arguments that predate his formulation, even going back as far as [[John Locke]].<ref>{{Citation |title=Frank Jackson Refutes His Own Knowledge Argument |url=https://www.youtube.com/watch?v=EN_lNAF8HoQ |access-date=2023-10-30 |language=en| time=11:00}}</ref>

[[C. D. Broad]], [[Herbert Feigl]], and [[Thomas Nagel]], over a fifty-year span, presented insight to the subject. Broad makes the following remarks, describing a thought experiment where an [[archangel]] has unlimited mathematical competences:

{{blockquote|He would know exactly what the microscopic structure of ammonia must be; but he would be totally unable to predict that a substance with this structure must smell as ammonia does when it gets into the human nose. The utmost that he could predict on this subject would be that certain changes would take place in the mucous membrane, the olfactory nerves and so on. But he could not possibly know that these changes would be accompanied by the appearance of a smell in general or of the peculiar smell of ammonia in particular, unless someone told him so or he had smelled it for himself.<ref>{{Harvnb|Broad|1925|p=71}}</ref>}}

In 1958, Feigl theorized that a hypothetical Martian, studying human behavior, will lack human sentiments.<ref>{{Harvnb|Feigl|1958|p=431}}</ref>

Nagel's essay "[[What Is It Like to Be a Bat?]]" takes a slightly different approach. He takes the perspective of humans attempting to understand the [[Echolocation (animal)|echolocation]] capabilities of bats. Even with the entire physical database at one's fingertips, humans would not be able to fully perceive or understand a bat's sensory system, namely what it is like to "see" the world through sound.<ref name=plato>{{cite encyclopedia|url=http://plato.stanford.edu/entries/qualia-knowledge/ |first=Martine |last=Nida-Ruemelin |title=Qualia: The Knowledge Argument |encyclopedia=Stanford Encyclopedia of Philosophy|publisher=Metaphysics Research Lab, Stanford University |year=2015 }}</ref>
