"Need we add that mathematicians themselves are not infallible?"
About this Quote
Poincare slips the knife in with a smile. The line reads like a casual aside, but it undercuts an entire cultural fantasy: that mathematics is a frictionless pipeline from pure reason to pure truth, untouched by human fallibility. By aiming the doubt not at math but at mathematicians, he protects the discipline's grandeur while reminding us who actually does the work: people with habits, egos, blind spots, and social incentives.
The rhetorical move is slyly modern. "Need we add..". feigns inevitability, as if any reasonable adult already knows this. That faux modesty is the point. It turns the reader into a co-conspirator against the kind of reverence that treats proofs as scripture and mathematicians as priests. Poincare, a major figure in the late-19th/early-20th-century struggle to formalize math and grapple with its foundations, was writing in an era when confidence in scientific objectivity was both soaring and starting to crack. Paradoxes and foundational disputes were beginning to show that rigor isn't just a moral virtue; it's a negotiated practice.
The subtext is also institutional: errors survive because communities let them. Mathematicians can be wrong, but they can also be collectively wrong for a while, protected by prestige, fashion, or the sheer difficulty of checking work. Poincare hints at a healthier picture of knowledge: not an oracle but a system with error-correction, where certainty is earned socially through verification, not granted by title. It's humility deployed as quality control.
