“When you plant a fertile meme in my mind you literally parasitize my brain, turning it into a vehicle for the meme's propagation in just the way that a virus may parasitize the genetic mechanism of a host cell.”

“Most people think of viruses as parasites, but they aren't parasites at all. An organism has to be considered alive to be classified as a parasite. Viruses don't do any of things living organisms do. They don't grow, they can't move on their own, and they don't metabolize. They don't even have cells. But the one thing a virus is very good at is reproducing. When it finds a suitable host cell, it attaches itself and injects its DNA through the cell's plasma wall. The virus's genes are transcribed into the host cell's DNA, and the host cell's genetic code is rewritten. Whatever its job was before, its new job is to do nothing but produce copies of the original virus, usually until it's created so many that the cell bursts open and spreads the infection.”

“Examples of memes are tunes, ideas, catch-phrases, clothes fashions, ways of making pots or of building arches. Just as genes propagate themselves in the gene pool by leaping from body to body via sperms or eggs, so memes propagate themselves in the meme pool by leaping from brain to brain via a process which, in the broad sense, can be called imitation.”

“Evolution itself embodies an ongoing exchange of information between organism and environment .... The gene has its cultural analog, too: the meme. In cultural evolution, a meme is a replicator and propagator — an idea, a fashion, a chain letter, or a conspiracy theory. On a bad day, a meme is a virus.”

“People who dismiss the unemployed and dependent as ‘parasites’ fail to understand economics and parasitism. A successful parasite is one that is not recognized by its host, one that can make its host work for it without appearing as a burden. Such is the ruling class in a capitalist society.”

“The idea that memes exist is a meme meme. ”
