Tom Hanks told graduates of Harvard University yesterday to be superheroes in their defense of truth and American ideals, and to resist those who twist the truth for their own gain. “For the truth to some is no longer empirical. It’s no longer based on data, nor common sense, nor even common decency,” said Hanks during his keynote address. He invoked the Latin word for truth, “veritas,” Harvard’s motto. “Telling the truth is no longer the benchmark for public service,” he said. “It’s no longer the salve to our fears, or the guide to our actions. Truth is now considered malleable, by opinion and by zero sum endgames.” “It’s the same option for all grownups who have to decide to be one of three types of Americans: Those who embrace liberty and freedom for all; those who won’t; or those who are indifferent,” he said. “Only the first do the work of creating a more perfect union, a nation indivisible. The others get in the way.”
