what does victor frankenstein mean by "Man how ignorant art thou in thy pride of wisdom"?

“Man, how ignorant art thou in thy pride of wisdom!” is a statement of irony. The magistrate judges Victor's reaction to Clerval's body in order to assess his guilt, and yet he does not see it. The magistrate's pride overran his wisdom in the same way Victor's ignorance and pride led to the monster's creation in the first place.

Well, I disagree with the above answer. The death in chapter 23 is Elizabeth's, not Clerval's. Victor had gone to the magistrate to tell what Victor himself had created and that the creature needed to be apprehended and convicted for his crimes.This quote is generally saying that the magistrate is very basically being an idiot when he knows he has the knowledge. It is ironic because Victor was the same way in making the creature, he had the knowledge but was too prideful and ignorant to apply the consequences of his actions.
