Which of the literary devices involves giving human characteristics is to nonhuman things?

Personification.

An example of this literary devide would be:

"The sun smiled down at me."

the Sun cannot smile, therefore this sentence uses personification

I hope this helps :)

Explanation:

Hamlet explores the theme "The desire for revenge is destructive and ultimately pointless." Even though Laertes is ultimately able to forgive Hamlet, Laertes dies in his quest for revenge. This shows both the destructiveness and the futility of trying to get revenge.
