John Galt

As the plot unfolds, Galt is acknowledged to be a philosopher and inventor; he believes in the power and glory of the human mind, and the rights of individuals to use their minds solely for themselves. He serves as a highly individualistic counterpoint to the collectivist social and economic structure depicted in the novel, in which society is based on oppressive bureaucratic functionaries and a culture that embraces mediocrity in the name of social egalitarianism, which the novel posits is the result of collectivist philosophy.
