what do we gain by having a direct access to all the character's thought and motives ?

"Sons and Lovers" is written in the third-person omniscient, which allows the reader to have access to each character's point of view and perspective. Third person limited limits the reader to the point of view of one characters, whereas in third-person omniscient gives us direct access to all the characters thoughts and motives.....thus, we are better able to understand the events.
