In 1953 Ray Bradbury wrote the novel Fahrenheit 451. The plot is set in a fictional, North American future. This essay aims to show that what is considered normal regarding fundamental values such as knowledge, love, and respect in this imaginary future society is different from what was considered normal in North America in the 1950s when Bradbury wrote the book. The norms differ to such an extent that it is possible to claim that Fahrenheit 451 is set in a new episteme. Episteme is a term used by the French philosopher Michel Foucault. It designates a time in which society has an underlying understanding of what is considered normal. According to Michel Foucault, the year 1953 when Bradbury wrote the book, belonged to the episteme of Modernity. This essay aims to illustrate that in the future fictional society of Fahrenheit 451, the norm regarding some aspects of the culture has changed to the extent that there is reason to call the era a new episteme, and that a proper name would be the episteme of Ignorance. This name signals the lack of regard for knowledge in the society of Fahrenheit 451. This essay's analytical tools are Michel Foucault’s terms, theories, and concepts.
