Mysterianism
Some philosophers, such as Chomsky and McGinn [5][6], argue that it is not possible for humans to understand consciousness because we are not equipped to do so. Such positions are called mysterianism, generally by people who don’t like it.
Mysterianism come in two forms, epistemological mysterianism which asserts that while a good physical explanation for consciousness exists, our brains are incapable of comprehending it in the same way that algebra is incomprehensible to an ape. The other form is called ontological mysterianism which asserts that no explanation within the physical realm exists at all and, as such, it is dualistic.
