Minor Wisdom -a thought for the day

From Minor Wisdom comes this thoughtful quote:
“With most species, communication occurs only in four contexts: mating, the care of the young, cooperation in obtaining food or territory, and fighting within the species or against predators. There is a vast quantity of human communication that cannot possibly be related, even mediately, to any of these four factors. Man does not live by bread alone: his other necessity is communication.”
