If that’s true, if human eloquence can be traced from a primal message signifying “Gimme,” I’m not sure what conclusion to draw about our species. Maybe that we are inherently social creatures who survived and prevailed against mightier animals by learning to enlist the cooperation of others. Or maybe just that, in our heart of hearts, we are all slackers.
The meaning of the gesture is clear whether it’s with one upturned palm, the “Brother, can you spare a dime” stance of beggars around the world, or with the two-palm version favored by preachers who reach out to beseech divine assistance. Or by exasperated Hollywood directors who rise from their chairs with upturned palms to implore their actors, “Work with me, people!”
The upraised palm is the automatic accompaniment to an apology or an alibi. As you try blaming the computer for eating your homework, you shrug your shoulders and expose your palms as a show of helplessness. What could I do? How could I know?
