This year half a century has passed since Thomas Nagel published his paper “What is It Like to Be a Bat?”, see here.
This is a seminal paper. It reaches out far beyond most discussions on the problem of consciousness - even in today’s context of philosophy of mind and of neuroscience.
One of the current experts in the scientific investigation of consciousness, notably of the neural correlates of consciousness (NCC), recalls in his book “Christof Koch: Consciousness" his initial lack of understanding. Lack of understanding when one of Koch’s colleagues pointed out that the results about NCC describe what happens, but they do not explain it.
In Nagel’s words: We want to know what it is like for an other person to have conscious perceptions. What it is like for him/her? The title of Nagel's work visualizes the gap between first-person experience and third-person level explanation - by substituting a bat for the other person.
Nagel uses the bat example to articulate his categorical doubt about the necessary capability of human cognition:
My realism about the subjective domain in all its forms implies a belief in the existence of facts beyond the reach of human concepts. […] But one might also believe that there are facts which could not ever be represented or comprehended by human beings, even if the species lasted forever – simply because our structure does not permit us to operate with concepts of the requisite type. (p. 441)
Does it make sense, in other words, to ask what my experience are really like, as opposed to how they appear to me? (p. 448)
My questions:
- During the last half century, which philosophers did follow Nagel and have elaborated on the principal boundaries of our cognitive capabilities?
- On the opposite, which philosophers or neuroscientists have elaborated an argument that it is a meaningful and possible task to explain the subjective feeling of conscious perception? Which type of answer could be accepted as a solution?
Note: The present question is related to two previous questions on this platform here and here.
