Growing up, assimilating the wisdom of the past, is in great part learning how to organize the sensorium productively for intellectual purposes. Man’s sensory perceptions are abundant and overwhelming. He cannot attend to them all at once. In great part a given culture teaches him one or another way of productive specialization. It brings him to organize his sensorium by attending to some types of perception more than others, by making an issue of certain ones while relatively neglecting other ones. The sensorium is a fascinating focus for cultural studies. Given sufficient knowledge of the sensorium exploited within a specific culture, one could probably define the culture as a whole in virtually all its aspects.

Walter Ong, S.J., from The Presence of the Word (1967). I’m going to spend a lot of time in the coming year meditating on this passage.
