Memetics
Memetics is a theory of mental content based on an analogy with Darwinian evolution, which was originated by Richard Dawkins and Douglas Hofstadter in the 1980s. It purports to be an approach to evolutionary models of cultural information transfer. A meme, analogous to a gene, is an idea, belief, pattern of behaviour (etc.) which is "hosted" in one or more individual minds, and which can reproduce itself from mind to mind. Thus what would otherwise be regarded as one individual influencing another to adopt a belief is seen memetically as a meme reproducing itself. As with genetics, particularly under Dawkins's interpretation, a meme's success may be due its contribution to the effectiveness of its host (i.e., the meme is a useful, beneficial idea), or may be "selfish", in which case it could be considered a "virus of the mind".
