Subjective and Objective

The supposedly separate realms of the subjective and the objective are actually only poles of attention. The dualism of observer and environment is unnecessary. The information for the perception of "here" is of the same kind as the information for the perception of "there," and a continuous layout of surfaces extends from one to the other. . . . Self-perception and environment perception go together.
