Answer:
The one argument seen between Henry and Waldo was over Emerson's lack of activism.
Explanation:
'The Night Thoreau Spent in Jail' is a two-act play written by Jerome Lawrence and Robert E. Lee. The play is based on the night when Henry David Thoreau spent in jail for refusing to pay poll-tax. Thoreau believed that the government will use these taxes to fund in Mexican-American War, which was sternly opposed by Thoreau.
Henry David Thoreau and Ralph Waldo Emerson have a very good friends, yet there was one scene in the play, when Henry and Waldo argues. It is in Act II, when Henry protests against Emerson's lack of activism. Henry protests that Waldo has great influence in public and thus he should use this influence to protest for the release of slaves like Williams. Henry accuses Waldo of not practising what he preaches. After this argument Waldo agrees to give a speech.
