Thesubjective character of experience is a term in psychology and thephilosophy of mind denoting that allsubjectivephenomena are associated with a singlepoint of view ("ego"). The term was coined and illuminated byThomas Nagel in his famous paper "What Is It Like to Be a Bat?"[1]
Nagel argues that, because bats are apparentlyconsciousmammals with a way of perceiving their environment entirely different from that ofhuman beings, it is impossible to speak of "what is it like tobe a batfor the bat" or, while the example of the bat is particularly illustrative, any conscious species, as each organism has a unique point of view from which no other organism can gatherexperience.[citation needed] To Nagel, the subjective character of experience implies thecognitive closure of the humanmind to some facts, specifically themental states thatphysical states create.
