“Although the far territory of the extreme can exert an intoxicating pull on susceptible individuals of all bents, extremism seems to be especially prevalent among those inclined by temperament or upbringing toward religious pursuits. Faith is the very antithesis of reason, injudiciousness a crucial component of spiritual devotion. And when religious fanaticism supplants ratiocination, all bets are suddenly off.”

American writer and mountaineer

Jon Krakauer is an American writer and mountaineer.

He also wrote numerous magazine articles. Krakauer was part of the 1996 Everest expedition that ended in disaster, and that experience later became the basis for Into Thin Air. His work often examines the risks people take, and the human cost of ambition, belief, and survival.
