Meerloo at source line 2410: "However paradoxical it may sound, democracy is founded on the mutual loyalty of politically opposed groups! You cannot doubt the good motives and intentions of your opponent without undermining the basis for cooperation and successful government. It is most undemocratic to impute disloyalty to the opposition party."
Followed at line 2412: "Democracy is nonconformity; it is mutual loyalty, even when we have to attack one another's ideas — ideas, which, because they are always human, are always incomplete."
This is the cleanest single-line definition of democracy in the postwar literature, and it sits in the middle of a chapter on loyalty oaths that almost nobody cites. The phrase reads, in 2026, like a diagnostic of a specific kind of democratic failure — the failure that occurs when major political factions stop granting each other basic good faith. The framework is structurally simple. Democracies do not require political agreement. Democracies require mutual loyalty across disagreement — the willingness to lose elections without claiming the system is corrupt, the willingness to consider that opponents have legitimate concerns, the willingness to debate ideas without imputing bad motive to those who hold them. When this substrate erodes, the same arguments produce different system outcomes. Democratic argument with the substrate intact is productive. Democratic argument without it is corrosive.
Same domain: extends The Loyalty Compulsion and Oath Paradox — the page that documents the apparatus; this spark is the population-level operational consequence.
Counterpoint to vault's existing Hoffer-conviction-binding framework: Hoffer treats deep ideological commitment as the engine of mass movement participation. Meerloo's frame treats cross-opposition mutual loyalty as the more important political variable, and predicts that populations with high in-group conviction-binding plus low cross-opposition loyalty are most susceptible to authoritarian capture — because the conviction supplies the fuel and the absent loyalty removes the brakes. The two frames address different but interacting variables.
