Tom Hanks urged Harvard graduates to defend the truth and

resist indifference in his commencement speech on Thursday. 

"There ain't no Superman, nor anyone else in his Justice League," Hanks said. 

"But we need to be champions for truth and justice." 

Hanks warned against the dangers of indifference, saying that it "kills truth, 

endangers the struggle for equality, and which I term worse than lies, ignorance, and intolerance." 

He also spoke about the importance of education, saying that it is "the great equalizer." 

He urged the graduates to use their education to make a difference in the world. 

"You are the ones who will go out into the world and make it a better place," Hanks said. 

You are the ones who will defend the truth, resist indifference, and create a more just and equitable society."
