Viruses of the Mind

"Viruses of the Mind" is an essay by British evolutionary biologist Richard Dawkins, first published in the book Dennett and His Critics: Demystifying Mind (1993). Dawkins originally wrote the essay in 1991 and delivered it as a Voltaire Lecture on 6 November 1992 at the Conway Hall Humanist Centre. The essay discusses how religion can be viewed as a meme, an idea previously expressed by Dawkins in The Selfish Gene (1976). Dawkins analyzes the propagation of religious ideas and behaviors as a memetic virus, analogous to how biological and computer viruses spread. The essay was later published in a A Devil's Chaplain (2003) and its ideas are further explored in the television programme, The Root of All Evil? (2006).

Dawkins defines the "symptoms" of being infected by the "virus of religion", providing examples for most of them, and tries to define a connection between the elements of religion and its survival value (invoking Zahavi's handicap principle of sexual selection, applied to believers of a religion). Dawkins also describes religious beliefs as "mind-parasites", and as "gangs [that] will come to constitute a package, which may be sufficiently stable to deserve a collective name such as Roman Catholicism ... or ... component parts to a single virus".

Dawkins suggests that religious belief in the "faith-sufferer" typically shows the following elements:

Dawkins stresses his claim that religious beliefs do not spread as a result of evidence in their support, but typically by cultural transmission, in most cases from parents or from charismatic individuals. He refers to this as involving "epidemiology, not evidence". Further Dawkins distinguishes this process from the spread of scientific ideas, which, he suggests, is constrained by the requirement to conform with certain virtues of standard methodology: "testability, evidential support, precision, quantifiability, consistency, intersubjectivity, repeatability, universality, progressiveness, independence of cultural milieu, and so on". He points out that faith "spreads despite a total lack of every single one of these virtues".
