Models and the problem of
(This is part of a series of informal notes, taken during ongoing collaborative conversations on the subject of the problem of consciousness.)
The systematic study of any subject involves first, a question or problem, second, a hypotheses or model of an answer and third, experimentation against that model.
There are many models for tackling the problem of consciousness. A biologist uses biological models, a psychologist psychological ones, a theologian religious ones and so on.
There are also archaic models of consciousness that may be of use. For more on this, see Mirce Eliade's survey, Shamanism: Archaic Techniques of Ecstasy.
The archaic model of consciousness is of the universe as a layered or nested series of landscapes that can be explored.
