n. A belief, expressed by survivalists, in being prepared to survive disasters and cataclysms including the collapse of civilization.

"While it may look like these Wall Streeters are betting on such a collapse, their embrace of survivalism is an outgrowth of their professional habits of mind: Having observed the economy’s shaky high-wire act from their ringside seats, they are trying to manage their risk and “hedge” against a potential fall."
