" Hay un concepto que es el corruptor y el desatinador de los otros. No hablo del Mal cuyo limitado imperio es la ética; hablo del infinito. Yo anhelé compilar alguna vez su móvil historia. La numerosa Hidra (monstruo palustre que viene a ser una prefiguración o un emblema de las progresiones geométricas) daría conveniente horror a su pórtico; la coronarían las sórdidas pesadillas de Kafka y sus capítulos centrales no desconocerían las conjeturas de ese remoto cardenal alemán—Nicolás de Krebs, Nicolás de Cusa—que en la circunferencia vio un polígono de un número infinito de ángulos y dejó escrito que una línea infinita sería una recta, sería un triángulo, sería un círculo y sería una esfera (De docta ignorantia, I, 13). Cinco, siete años de aprendizaje metafísico, teológico, matemático me capacitarían (tal vez) para planear decorosamente ese libro. Inútil agregar que la vida me prohibe esa esperanza, y aún ese adverbio..."

Jorge Luis Borges en Avatares de la Tortuga.
