Victor Hugo in the novel Les Miserables and Eugène Ionesco in the play Rhinocéros, both want to prove that man needs courage to save himself. The invasion of rats from Paris’ sewers was replaced in Ionesco’ play, by the invasion of rhinoceros, basically, bearers of the same evil symbolism that can occur in any form or by any means. Rats would live in sewers, rhinos appear in the street. The offensive is equally destructive, whether it appears from within, or from the outside. We all have to determine who the real rats or rhinos invading us, rhinos which want us to resemble them, and which is the way that suits us best, to save ourselves form transformation. There isn’t a second awareness that can decide the way to happiness, for us. We are masters of our own condition.
