 Finally, we should note that on Husserl’s view there is a further important dimension to perceptual experience, in that it displays a phenomenological deep- or micro-structure constituted by time-consciousness (Husserliana, vol. X, XXXIII; also see Miller 1984). This merely seemingly unconscious structure is essentially indexical in character and consists, at a given time, of both retentions, i.e., acts of immediate memory of what has been perceived “just a moment ago”, original impressions, i.e., acts of awareness of what is perceived “right now”, and protentions, i.e., immediate anticipations of what will be perceived “in a moment”. It is by such momentary structures of retentions, original impressions and protentions that moments of time are continuously constituted (and reconstituted) as past, present and future, respectively, so that it looks to the experiencing subject as if time were permanently flowing off.
