Fortress Mentality

Definition

The fortress mentality is Jane Jacobs's name for the cultural xenophobia that succeeds decline from vigor: "Cultural xenophobia is a frequent sequel to a society's decline from cultural vigor. Someone has aptly called self-imposed isolation a fortress mentality" (Jacobs 2004, p. 17). Its theoretical content comes through Karen Armstrong's history of Islam: the shift "from faith in logos, reason, with its future-oriented spirit, 'always … seeking to know more and to extend … areas of competence and control of the environment,' to mythos, meaning conservatism that looks backward to fundamentalist beliefs for guidance and a worldview" (quoted p. 17). The concept has a double structure: "A fortress or fundamentalist mentality not only shuts itself off from dynamic influences originating outside but also, as a side effect, ceases influencing the outside world" (p. 17) — the fortress is simultaneously a refusal of input and a forfeiture of output.

Jacobs's cases: Mesopotamia after 1492 — from the expulsion of Muslims from Spain until the early nineteenth century, Mesopotamia "deliberately attempted to shield itself from influences coming from the outside world," the retreat that ended the region's second burst of world-altering scientific creativity (p. 17); China after 1433, whose wrong turning "carried the double blow of surrender of its technological lead and simultaneous retreat into a fortress mentality," the mythos for which logos was surrendered being Confucianism (p. 19); and Japan as the counter-case — a country that had "adopted a fortress mentality" before 1853 yet, when Perry's gunboats forced it open, "assimilated Western ways into its own culture, rather than allowing its own culture to become irrelevant while it was emulating the West" (p. 172). The concept's diagnostic value is temporal: fortress mentality is a sequel, a symptom of decline rather than its cause — and it accelerates the decline it follows, since the fortress ceases both learning and teaching.

Key Thinkers

• Jane Jacobs — the concept's theorist: cultural xenophobia as decline's sequel; the double loss (input and influence); the Japan counter-case (2004).
• Karen Armstrong (not yet paged — see log) — the logos→mythos framework from Islam: A Short History (2000), on which Jacobs's definition rests.
• Henri Pirenne (not yet paged — see log) — the historian whose medieval-cities account gives the concept its economic-historical backdrop (trade revival against isolation).

Related Concepts

• dark-age — the collapse the fortress mentality both signals and deepens.
• mass-amnesia — the mechanism the fortress completes: cut off from outside influences, a culture can no longer borrow its way back to memory.
• postagrarian-society — the contemporary jolt that tempts fortress retreat: Armstrong's postagrarian analysis explains why modernization produces fundamentalist reaction in agrarian societies.
• vicious-spirals — the dynamic the fortress exemplifies: each withdrawal strengthens the decline that prompted it.

• Dark Age Ahead (Jacobs 2004) — the concept's source: the xenophobia-as-sequel thesis and the Armstrong logos/mythos quotation (p. 17); the double loss formulation (p. 17); Mesopotamia after 1492 (pp. 16–17); China's 1433 retreat and the destroyed voyage archives (p. 19); Japan's assimilation as the counter-pattern (p. 172).

Open Questions

• Is the fortress mentality a concept of civilizational scale only, or does it have an urban register — the gated community, the enclave, the hostile perimeter? The wiki's privatised-public-space and gated-community pages hold a spatial vocabulary that this concept has not yet been connected to.
• Armstrong's logos/mythos pair is a religious-history framework. Does Jacobs's borrowing flatten it — and is the "fundamentalist" label applied to Confucian China and to modern America (the War on Terrorism's rights surrenders, p. 60) doing the same analytical work?
• Japan's assimilation-without-loss is the concept's exception that proves the rule. What distinguishes adaptive opening from fortress collapse — is the variable the presence of an intact cultural core to assimilate into (Japan's living national treasures, Ireland's songs)?
