Rosencrantz and Guildenstern Are Dead Fear Quotes

How we cite our quotes: Citations follow this format: (Act.Line). Every time a character talks counts as one line, even if what they say turns into a long monologue.

Quote #1

GUIL: Is that what you imagine? Is that it? No fear?
ROS: Fear?
GUIL (in fury – flings a coin on the ground): Fear! The crack might flood your brain with light! (1.47-49)

Why would fear "flood your brain with light," as Guil puts it? Does fear open up new perceptions and change the way we look at things, or does it just paralyze us?

Quote #2

ROS: I'm afraid –
GUIL: So am I.
ROS: I'm afraid it isn't your day.
GUIL: I'm afraid it is. (1.51-54)

How is Ros and Guil's fear different here? Ros is just trying to sympathize with Guil, isn't he? Does Guil notice that Ros is being sympathetic, or is he too focused on whether or not the long string of coins coming up heads is a sign?

Quote #3

GUIL: The scientific approach to the examination of phenomena is a defence against the pure emotion of fear. (1.74)

Does the world become less frightening when we think that we understand it? Is Guil's statement actually true of science or just of his spontaneous syllogisms?
