Natasha insists that human beings aren't reasonable creatures, as they're ruled by emotions instead of logic. She thinks that the world would be better if logic ruled, especially since after her phone call to the attorney's office, she's started hoping for a miracle. She notes that she doesn't even believe in God.
Natasha believes that there's no middle ground between rationality and passion; as far as she's concerned, the two ideas do not exist on a spectrum. However, her change of heart suggests she might be wrong about this.
