de una forma canónica, se encuentra su presunta realización geométrica. Pero,
mientras tanto, descubrimos que no todo está dicho en este mundo matemático que
yuxtaponer resultados contradictorios que nadie puede decidir sin cuestionar
las prácticas que han demostrado su eficacia. Mientras que la perfección
euclidiana es socavada, la figuración geométrica no es más una realización,
sino una mera representación geométrica. Nuestra entidad en cuestión resiste a
figuraciones geométricas, que se abren como tantos cálculos, y se requiere para
su existencia un exclusiva aritmética-algebraica que libera de singular manera
el número complejo.</span></p>

trabajo del suizo Jean-Robert Argand, matemático de "segundo nivel"

el camino para los números complejos.</span></p>
