The Idea enters the brain from the outside. It rearranges the furniture to make it more to its liking. It finds other Ideas already in residence, and picks fights or forms alliances. The alliances build new structures, to defend themselves against intruders. And then, whenever the opportunity arises, the Idea sends out its shock troops in search of new brains to infect. The successful Idea travels from mind to mind, claiming new territory, mutating as it goes. It’s a jungle out there, Adam. Many Ideas are lost. Only the strongest survive.
