Hamlet
RALPH: Well, Sarah, Hamlet seems clearly depressed — he just wants to melt away and disappear; he would even commit suicide — "self-slaughter" as he calls it — if it weren't against Biblical commandments. And like most depressed people, he sees the world as grey and useless; everything is "weary, stale, flat and unprofitable".
SARAH: True enough, Ralph. I should add that the monologue begins with strong visual imagery to help us see the world as bleakly as Hamlet is seeing it: first, Hamlet's wish that his solid flesh would melt away into an almost immaterial liquid; and then, the metaphor of the world as an unweeded garden, gone to seed, and overrun by stinking plants. Both give us a sense of Hamlet's despair that God has abandoned his material creations.
