Anil Ananthaswamy in Nautilus:
While aging diminishes activity in certain brain regions, there’s tantalizing evidence this may be compensated by changes in brain regions associated with supportive and social behavior. This shift in brain activity may foster wisdom in some people, a way of being that moves one away from self-centeredness toward emotional equanimity and wider social consciousness. We may even be able to work toward wisdom in old age. For millennia, philosophers and theologians have been preoccupied with the notion of wisdom (the Greek word philosophia means “love of wisdom”). Centuries before the Greeks got into the act, the religious traditions of India and China, such as Hinduism, Buddhism, and Daoism, were thinking about wisdom, emphasizing the regulation of emotion—or emotional balance—as key to it. Aristotle delineated wisdom into two types. One was the general, god-like, all-knowing wisdom, and the second (more pertinent to us mere mortals) was something called phronesis, or practical wisdom, which is the ability to be discerning about one’s actions, knowing when and why to act in a pragmatic manner. Ideally, such wise actions—whether involving emotion regulation or reasoning—would balance self-interest against the interests of others and those of society in general.
