On the other hand a crucial difference between Keats and Rossetti lies in how their writings depict the tripartite model of the mind consisting of the id ego and superego In The Eve of St Agnes the feast Porphyro sets up for Madeline stimulates erotic desire Garofalo 357 It represents the propensity of the id for pleasure seeking taking precedence over moral precepts as Porphyro partakes in stolen enjoyment from eastern trade and his enemies 358 The desires of the id are also represented in Porphyro s wish to voyeuristically enjoy Madeline This is countered by Angela the old woman he meets in the hallway who acts as the superego or the mind s conscience She initially declines his request but Porphyro eventually persuades her to lead him to Madeline s chamber Her actions represent the ego as it is the final decision made after considering both the id and the superego In this case the id received a more favorable result The story could be interpreted as Keats endorsing a philosophy that maximizes happiness utilitarianism since Porphyro seeking to maximize his enjoyment leads to good consequences
