"No problem can withstand the assault of sustained thinking"
About this Quote
Voltaire frames thought as siegecraft: not a polite parlor activity, but a sustained assault that breaks a problem’s defenses. The phrasing is deliberately martial and a little smug, the Enlightenment’s signature move - reason not merely as a tool, but as a moral weapon. “Withstand” implies the problem is an adversary with fortifications; “sustained” suggests most failures are not about intelligence but stamina. It’s less a compliment to genius than a jab at laziness, superstition, and the convenient fog of received wisdom.
The subtext is Voltaire’s lifelong quarrel with institutions that depend on people not thinking too hard: churches guarding doctrine, monarchies guarding privilege, censors guarding social peace. If a difficulty persists, he implies, it’s often because someone benefits from its permanence - or because fear and habit keep inquiry brief. “Assault” also carries a faintly transgressive charge: thinking becomes an act of resistance, a way of violating taboo boundaries without lifting a sword.
Context matters because Voltaire lived in a Europe where ideas could get you exiled, imprisoned, or financially ruined. Sustained thinking wasn’t just solving puzzles; it was daring to keep looking when the state or the pulpit demanded you stop. The line flatters the Enlightenment project while exposing its wager: that reason, relentlessly applied, can dissolve not only technical knots but the social fictions that props them up. It’s a rallying cry disguised as a maxim - impatient with mystique, allergic to resignation, confident that clarity is corrosive.
