For Clark, in oblivion there is even an absence of experience, as we can only speak of experience when a subjective self exists. According to neuroscientist Giulio Tononi, consciousness is "all we are and all we have: lose consciousness and, as far as you are concerned, your own self and the entire world dissolve into nothingness." [18]
Consciousness: How can consciousness be defined? What is the neural basis of subjective experience, cognition, wakefulness, alertness, arousal, and attention? Binding problem: How exactly is it that objects, background, and abstract or emotional features are combined into a single experience? What is the neural basis of self?
Other researchers accept the problem as real and seek to develop a theory of consciousness' place in the world that can solve it, by either modifying physicalism or abandoning it in favour of an alternative ontology (such as panpsychism or dualism). A third response has been to accept the hard problem as real but deny human cognitive faculties ...
The notion that quantum physics must be the underlying mechanism for consciousness first emerged in the 1990s, when Nobel Prize-winning physicist Roger Penrose, Ph.D., and anesthesiologist Stuart ...
The Polish science-fiction writer Stanisław Lem described the same problem in the mid-twentieth century. He put it in writing in his philosophical text Dialogs in 1957. . Similarly, in Lem's Star Diaries ("Fourteenth Voyage") of 1957, the hero visits a planet and finds himself recreated from a backup record, after his death from a meteorite strike, which on this planet is a very commonplace proc
[c] Also, the fact that the easiest 'content of consciousness' to be so analyzed is "the experienced three-dimensional world (the phenomenal world) beyond the body surface" [31]: 4 invites another criticism, that most consciousness research since the 1990s, perhaps because of bias, has focused on processes of external perception.
Far more animals than previously thought likely have consciousness, top scientists say in a new declaration — including fish, lobsters and octopus. Recent research backs them up.
A key aspect of the mind–body problem is the hard problem of consciousness or how to explain that physical systems like brains can produce phenomenal consciousness. [84] The status of free will as the ability of a person to choose their actions is a central aspect of the mind–body problem. [85]
