When describing the events in the woods, count how many times hawthorne uses ambiguous language in diction like seems, must, appears, perhaps, and maybe. why does hawthorne want to leave all this so ambiguous? why not tell us clearly whether something is happening or not happening?

I believe the answer is: He wants us to figure out the deeper meaning for ourselves

One disadvantage of Ambiguous words is that it often took more time for the readers to finish a certain book/writings. The advantage on the other hand, it forced the leader to analyse the meaning of the words which often lead to deeper understanding on a certain topic.
