Middle Ages

The Selfish Gene

The Middle Ages are invoked as a period in which the threat of hellfire caused psychological anguish and helped enforce religious observance. In the book’s account of memes, this historical example shows how a doctrine can persist by affecting the minds that transmit it, reinforcing the idea of God and other mutually supporting elements of an organized religion.

Hellfire and Religious Observance

The threat of torment after death is presented as an especially effective means of enforcing priestly rules. Children, and even some adults, believed they would suffer ghastly torments if they disobeyed. The account stresses the cost of this persuasion: it caused psychological anguish during the Middle Ages and continued to do so in the author’s own time. Its effectiveness, however, also helps explain how the doctrine could be transmitted and maintained.

A Self-Reinforcing Religious Complex

Hellfire is not treated as an isolated belief. It is linked to the idea of God because the two reinforce each other: the threat of punishment strengthens the authority of religious rules, while belief in God gives the threat its force. The book compares this arrangement to a co-adapted set of memes, in which doctrine, organization, ritual, art, music, architecture, and written tradition may assist one another’s survival. The reference to the Middle Ages therefore belongs to an account of cultural transmission, not a chronology of particular events in the period.

Historical Example in the Meme Argument

The example illustrates the book’s distinction between a belief’s cultural survival and its truth. A religious meme may spread because of its psychological impact and its ability to support other memes; its persistence does not, by itself, establish that it is true. The Middle Ages give the argument historical weight: an idea can endure through successive minds not only because it offers comfort, but also because fear can make observance compelling.
