The Phrase Today
"Gadarene rush" or "Gadarene swine" is a primarily British idiom used to describe any headlong, collective rush toward self-destruction - a panicked, lemming-like stampede in which a crowd or institution abandons judgment and hurtles toward catastrophe. It is a favorite phrase of British political commentators, columnists, and satirists when describing financial markets in a bubble, political parties abandoning principles, or bureaucracies blindly implementing disastrous policies. While relatively rare in American English, it has strong currency in British educated discourse.
Biblical Origin
The story appears in Mark 5:1-13, Matthew 8:28-32, and Luke 8:26-33. Jesus encountered a demon-possessed man (or men, in Matthew) in the region of Gadara (or Gerasa). The demons possessing the man begged Jesus to cast them into a herd of swine. Jesus permitted this. Mark 5:13 (KJV) records: "And forthwith Jesus gave them leave. And the unclean spirits went out, and entered into the swine: and the herd ran violently down a steep place into the sea, (they were about two thousand;) and were choked in the sea."
The dramatic detail is the herd's size - two thousand animals - and the violence of the rush: hormesen in Greek, meaning a violent rush or charge. The pigs had no capacity to resist the forces driving them and simply ran, collectively and unstoppably, to their deaths. The image of two thousand animals stampeding off a cliff is one of the New Testament's most visually arresting scenes.
How the KJV Cemented It
The KJV's rendering "ran violently down a steep place" preserved the Greek hormesen kata tou kremnou (rushed down the cliff) in plain, forceful English. The phrase's entry into common idiom came through the pattern of educated Englishmen, schooled in the KJV, reaching for a precise image of mindless collective destruction. The word "Gadarene" - an adjective derived from the place-name Gadara - was coined by analogy with other biblical adjectives (Pharisaical, Herodian) and entered English as a modifier meaning "characterized by unthinking collective rush toward disaster."
Semantic Range
The phrase is used in several related but distinct senses:
1. Financial markets: A Gadarene rush into a speculative bubble - investors stampeding into a sector without rational analysis, driving prices to unsustainable heights before the inevitable crash. 2. Political parties: An institution abandoning its principles in a collective rush toward an ideological extreme or a popular but self-destructive position. 3. Bureaucratic processes: Policies or programs that, once set in motion, cannot be stopped even when their destructive consequences are clear. 4. General crowd behavior: Any situation where collective momentum overrides individual judgment and people do things in groups they would never do alone.
Historical Usage
The phrase appears in Victorian and Edwardian periodicals to describe financial panics and political upheavals. W.E. Gladstone used "Gadarene" as a political adjective. In the twentieth century, it became particularly associated with criticism of rapid social change - the welfare state, privatization programs, European integration - where critics argued that the speed and totality of change resembled a stampede rather than considered reform.
The Labour politician Aneurin Bevan, the Conservatives' Enoch Powell, and the journalist Bernard Levin all deployed the Gadarene image in political writing. The phrase became part of the standard vocabulary of British political commentary - a learned allusion that signaled both classical education and moral seriousness about collective folly.
Cross-Linguistic Reach
The phrase is almost exclusively an English idiom. Other European languages have their own ways to describe collective panic - French mouvement de masse, German Massenpanik - but lack the specific biblical allusion. The Gadarene story is known to educated Europeans in other languages, but the translation of the idiom never transferred. In English, the story's place in the standard Bible education of every grammar school child for centuries gave it an allusive currency that was lost in languages where secular education replaced Bible-based schooling earlier.
In Literature and Culture
The Gadarene episode has attracted attention from literary figures who found its imagery irresistible. Aldous Huxley invoked it in essays on crowd psychology. George Orwell's interest in the irrationality of mass movements drew on Gadarene imagery. In academic political science, the phrase describes "cascade" effects - situations where each actor follows the one before without independent analysis, producing collective outcomes no individual actor would have chosen.
The episode has also attracted theological attention: the pigs' destruction raises ethical questions about the use of animal life to save human wellbeing, the nature of demonic possession, and the relationship between Jesus's healing ministry and economic disruption (the pig owners lost their entire livelihood). These complexities make the story one of the New Testament's most theologically interesting miracles, beyond its contribution to English idiom.
Related Biblical Phrases
"Cast into outer darkness" (Matthew 8:12) is another phrase from the same chapter of Matthew, suggesting a thematic cluster of exclusion and destruction. "Legion" (Mark 5:9, the demon's name, meaning "many") is a related phrase that entered English as a descriptor for any vast and overwhelming multitude. "Separate the sheep from the goats" (Matthew 25:32) involves another scene of dramatic animal imagery with moral sorting.
Common Misconceptions
The most common misconception is that the Gadarene swine were mindlessly evil or deserved their fate - in context, they were innocent animals used as vessels by demonic forces. The moral of the story is about liberation and the power of Jesus over evil, not about the foolishness of pigs. Second, some users of the phrase assume it refers to the people of Gadara (who did indeed ask Jesus to leave after the miracle), but the idiom specifically derives from the pigs' rush, not the townspeople's reaction. Third, the story's location - Gadara, Gerasa, or Gergesa, depending on the Gospel - reflects variant manuscript traditions, making the precise geography uncertain, though none of this affects the idiom's meaning.
