The World State society, although seemingly perfect, has unquestionable flaws within it's control.

First, there is no true diversity within the society. One is either an alpha, beta, gamma, delta, or epsilon. Each one of these castes has a different duty. A person (engineered in a tube) does not have control over their future; their future is engineered for them for the good of the society.

Second, how the "perfect society" is engineered is flawed. Playing information and, in essence, brainwashing children while they are sleeping draws serious criticism.

Happiness is directly related to soma. It is said that a gram of soma gets rid of your troubles. Comparable to drugs in our time, soma in this era is what makes the people happy. The question, however, is are the people actually happy? Soma MAKES people happy, but many would argue that happiness is generated from within, not forced through drugs. This is where the truth comes into the equation. Are the people truly happy? Bernard and Helmholtz believe not. They believe that the people are not happy because they lack freedom. Freedom has been pushed down from childhood. Sometimes, that freedom attempts to surface as Helmholtz says "...feeling that I've got something important to say and the power to say it..." (69). However, for most, freedom is killed.
There is a strong connection between soma, truth, and happiness. Without soma, there is no happiness. Dreams caused by soma are not the truth, therefore, happiness is found at the expense of the truth. Is happiness worth the price of the truth?
