Complexity of experience
Large parts of Woolf's novel do not concern themselves with the objects of vision, but rather investigate the means of perception, attempting to understand people in the act of looking. To be able to understand thought, Woolf's diaries reveal, the author would spend considerable time listening to herself think, observing how and which words and emotions arose in her own mind in response to what she saw.
Complexity of human relationships
This examination of perception is not, however, limited to isolated inner-dialogues, but also analysed in the context of human relationships and the tumultuous emotional spaces crossed to truly reach another human being. Two sections of the book stand out as excellent snapshots of fumbling attempts at this crossing: the silent interchange between Mr. and Mrs. Ramsay as they pass the time alone together at the end of section 1, and Lily Briscoe's struggle to fulfill Mr. Ramsay's desire for sympathy (and attention) as the novel closes.
