Soyez donc des hommes, ou mieux : des surhommes ! Soyez fidèles aux buts tracés.
Frankenstein ou le Prométhée moderne
Contexte et précisions
En anglais : "Oh! Be men, or be more than men. Be steady to your purposes and firm as a rock. This ice is not made of such stuff as your hearts may be; it is mutable and cannot withstand you if you say that it shall not. Do not return to your families with the stigma of disgrace marked on your brows. Return as heroes who have fought and conquered, and who know not what it is to turn their backs on the foe."
