Susan Blackmore studies memes: ideas that replicate themselves from brain to brain like a virus. She makes a bold new argument: Humanity has spawned a new kind of meme, the teme, which spreads itself via technology -- and invents ways to keep itself alive. Bruno Giussani say, "[Susan Blackmore], she took Richard Dawkins' intuition about memes (ideas that, like genes, take a life of their own) and turned it into a fully fledged theory." Metaphor or science...?
