Definition

矛盾 (mujun): A contradiction. From the Chinese parable of a merchant who sells both an impenetrable shield and an all-piercing spear. When asked what happens when the spear strikes the shield, the merchant has no answer.

Paradox

if (spear.pierces(everything)) {
  if (shield.blocks(everything)) {
    // ???
    throw new ContradictionError();
  }
}

Etymology

矛 (mao/mu) = spear, halberd. 盾 (dun/jun) = shield. Together: 矛盾 = the impossible coexistence of absolute attack and absolute defense.

Applications

In philosophy: the limits of logical systems. In language: the self-referential paradox. In design: the tension between order and chaos. In life: everything.

The wiki format promises order. It promises that knowledge can be categorized, cross-referenced, and contained. Mujun resists containment. The contradiction between the container and the uncontainable IS the knowledge.

The encyclopedia of contradiction has no final entry. Every definition contains its own refutation. Every category dissolves under examination. The wiki is always incomplete, always contradicting itself, always rewriting. This is not failure. This is mujun.
