Theories of consciousness

In recent years, a central focus of research in the philosophy of mind has been consciousness and the philosophy of perception. While there is a general consensus for the global neuronal workspace model of consciousness, there are many opinions as to the specifics. The best known theories are Searle's naive realism, Fred Dretske and Michael Tye 's representationalism, Daniel Dennett 's heterophenomenology, and the higher-order theories of either David M. Rosenthal —who advocates a higher-order thought (HOT) model—or David Armstrong and William Lycan —who advocate a higher-order perception (HOP) model. An alternative higher-order theory, the higher-order global states (HOGS) model, is offered by Robert van Gulick.
