What's in a Meme?

James Gleick explains a continuum in Smithsonian Magazine:
What lies at the heart of every living thing is not a fire, not warm breath, not a ‘spark of life.’ It is information, words, instructions,” Richard Dawkins declared in 1986. Already one of the world’s foremost evolutionary biologists, he had caught the spirit of a new age. The cells of an organism are nodes in a richly interwoven communications network, transmitting and receiving, coding and decoding. Evolution itself embodies an ongoing exchange of information between organism and environment. “If you want to understand life,” Dawkins wrote, “don’t think about vibrant, throbbing gels and oozes, think about information technology.”

We have become surrounded by information technology; our furniture includes iPods and plasma displays, and our skills include texting and Googling. But our capacity to understand the role of information has been sorely taxed. “TMI,” we say. Stand back, however, and the past does come back into focus.

[…] Jacques Monod, the Parisian biologist who shared a Nobel Prize in 1965 for working out the role of messenger RNA in the transfer of genetic information, proposed an analogy: just as the biosphere stands above the world of nonliving matter, so an “abstract kingdom” rises above the biosphere. The denizens of this kingdom? Ideas.

“Ideas have retained some of the properties of organisms,” he wrote. “Like them, they tend to perpetuate their structure and to breed; they too can fuse, recombine, segregate their content; indeed they too can evolve, and in this evolution selection must surely play an important role.”

Ideas have “spreading power,” he noted—“infectivity, as it were”—and some more than others. An example of an infectious idea might be a religious ideology that gains sway over a large group of people.
