For instance, In the world state, the citizens all agree that they are happy and never hold opinions that conflict, however, Aristotle claimed in his Metaphysics: "If, however, all beliefs and appearances are true, then everything must be at the same time true and false. For many men hold opinions contrary to those of others and call deluded whoever does not think just as they do." "So, if everybody were sick or everybody insane and only two or three were well or sane, the latter would be thought sick and insane but not the majority."
As far as the issue of "What is happiness?" goes, in Huxley's World State, everyone is happy because they are predestined for what their role in society is. Aristotle claimed that happiness is the end in which men live their whole lives for; the end which they strive for, but he claimed that since "there are various actions, arts, and sciences, it follows that the ends are also various". Which means that although those in the World State may believe they are happy, they are in truth not, because they do not strive to attain their own happiness, but rather a happiness that stems from actions that they are predestined to do.
