 The position Broad reaches is the following. A perceptual experience has a certain intentional content. It differs from thought- and belief-episodes by including a sensory phase, and it is primarily this that is responsible for the distinctive phenomenology of perception. The sensory phase consists of sensations. These decompose into acts of sensing and object sensed, sensa. A sensum has the phenomenal properties that the perceived object (sensibly) appears to have—red or warm or squeaky. An act of sensing a sensum constitutes an immediate acquainting awareness of the sensum in question. Although our perceptual experiences seem to grant us an acquaintance with the facing surfaces of material objects, sensa are the only items we are acquainted with.
