In order to succeed we should not attempt the impossible, or flatter ourselves that we are giving the work of men a solidity that does not belong to human things.

Nadie se atreve ya a parecer lo que es; y en esta coacción perpetua, los hombres que conforman el rebaño llamado sociedad, situados en las mismas circunstancias, harán todos lo mismo si no se lo impiden motivos de fuerza mayor. Por lo tanto, nunca sabremos muy bien con quién nos enfrentamos; para conocer a un amigo será necesario esperar las grandes ocasiones, es decir, esperar el momento en que ya sea tarde, puesto que para esas mismas ocasiones habría sido esencial conocerlo.
