Answer:
This line shows Hamlet becoming more and more philosophical and confused (especially “I know not” phrase).
Step-by-step explanation:
This excerpt is from Shakespeare’s Hamlet (Act ii, Scene ii). In this scene Hamlet, when joined by his childhood friends, becomes more philosophical. Firstly he himself is not sure about the truthfulness of the story narrated by the Ghost (Hamlet’s father). Secondly his philosophical approach to consider the implications of revealing this truth publicly is making him confused.
