Plasticity is a double-edged sword: the more flexibile an organism is the
greater the variety of maladaptive, as well as adaptive, behaviors it can
develop; the more teachable it is the more fiully it can profit from the
experiences of its ancestors and associates and the more it risks being
exploited by its ancestors and associates; the greater its capacity for
learning morality the more worthless superstitions, as well as traditions
of social wisdom, it can acquire; the more cooperatively interdependent the
members of a group become the greater is their collective power and the
more fulsome are the opportunities for individuals to manipulate one
another; the more sophisticated language becomes the more subtle are the
lies, as well as the truths, that can be told.
