What would be some examples of what Huckleberry has learned through the course of The Adventures of Huckleberry Finn that would help him gain...

Huck has many experiences that should and do help him
grown and attain insights. He does not, however, always retain these lessons and these
insights as he moves forward. 

Early in the book, Huck
pretends to be a girl so that he can find out what the town is saying about Jim and what
they are saying about Huck's "death". In this episode, Huck is found out right away. The
woman he speaks to helps him anyway. This moment offers Huck the opportunity to see that
some people can be trusted and that lying is not always a necessary defense. Honesty can
serve just as well. 

Huck, nonetheless, continues to lie
throughout the novel. He does, at one point, repent for his deception. When he hurts
Jim's feelings and Jim articulates a disapproval of this behavior, Huck humbles himself
and vows not to fool Jim again. He realizes that his actions have an effect on
others. 

This lesson is put to the test when Huck finds
himself in the mess of the Wilks funeral with the King and the Duke. There, he decides
to be honest rather than to continue to hurt innocent
people. 

However, in the final, extended episode of the
novel, Huck once again chooses to lie and deceive. He plays a part in torturing both Jim
and Mrs. Phelps in order to carry out Tom's elaborate plan to free Jim. The lesson of
the benefits of honesty and the insight that his actions could bring emotional harm to
others seems to have faded quickly from Huck's mind.
