Quote by Mary Douglas

"Purity and danger are not intrinsic qualities of things, but classifications depending on how we view the world."

"Pollution is a matter of perspective and social order."

"What is unclassified is dangerous because it threatens our understanding of the world."

"Rituals are not irrational; they are expressions of social solidarity and order."

"We're not just after treasure. We're preserving history."

"The mind is humanity's greatest tool."

"A tidy room reflects a tidy mind."

"You can learn a lot about a person by how they keep their space."
