Since therefore the knowledge and survey of vice is in this world so necessary to the constituting of human virtue, and the scanning of error to the confirmation of truth, how can we more safely, and with less danger, scout intotheregions of sinand falsity thanby reading all manner of tractates and hearing all manner of reason? And this is the benefit which may be had of books promiscuously read.
Human sense organs can receive only news of difference, and the differences must be coded into events in time (i.e., into changes) in order to be perceptible. Ordinary static differences that remain constant for more than a few seconds become perceptible, only by scanning. Similarly, very slow changes become perceptible only by a combination of scanning and bringing together observations from separated moments in the continuum of time.Gregory Bateson
