In Rhinoceros, the gradual takeover of society by the beasts is made to seem natural and, therefore, inevitable. Eugene Ionesco presents the protagonist, Bérenger, as a conventional person with normal goals and aspirations. Initially, as he does not question his society’s values, he is not motivated to challenge them. Everyone is equally confused by the animals running loose. As a few individuals realize that the animals are transformed humans, they wonder what is happening but do not try to stop it. As more people change, Bérenger continues to observe but remains unaffected; he regards their behavior, like their new appearance, as aberrant. A few exceptions do not affect society overall.
Between acts 2 and 3, after his friend Jean becomes a rhinoceros and attacks him, Bérenger starts to understand that he is now in the minority, which everyone else identifies as abnormal. When his girlfriend, Daisy, leaves him to join the herd, he is left solitary and alienated. Because he clings to his humanity, now fiercely resisting the universal transformation, the human condition as Ionesco presents it is precisely that combination of isolation and resistance to mob rule.
