Subjectivity is, primarily, an aspect of consciousness. In a sense, conscious experience may be described as the way the world appears from a particular mental subject’s point of view. The idea that there is a distinction between appearance and reality seems to presuppose the distinction between subjective and objective points of view.
The two controversies
There are two principal controversies surrounding subjectivity: first, whether subjectivity, as it is manifested in consciousness, is an essential component of mentality; and second, whether subjectivity presents an obstacle to naturalistic theories of the mind.
THE FIRST CONTROVERSY. Most philosophers agree that intentionality—the ability to represent—is characteristic of mentality. However, there is strong disagreement over whether subjectivity is also necessary.
