In the New World of Aldous Huxley's dystopia, science absolutely dictates the lives of the people. From their "birth" in the Hatchery where they are cast as an Alpha, Beta, Delta, Gamma, or Episolon, they are conditioned by hypnopoedia to like and dislike certain things and certain castes, to be satisfied with what they are, to believe that "everyone belongs to everyone else" and to revile monogomy, to be repulsed by natural births, to detest nature, to desire to consume. Most of the women are designed to be Free Martins, who are infertile, while others must take certain drugs to control their urges to become mothers.
The Solidarity Service with its orgy-porgy replaces religious ceremony; the "feelies" satisfy other urges; soma washes away any discontent from their minds. Science also prevents them from aging, but when they do die, their bodies become part of phosphorous recovery and are recycled by science as gases.
