Solipsism is the view or theory that self is the only object of real knowledge, or the only thing that really exists.
(Thanks, Dungeons & Dragons, for teaching me this at a young age, by depicting a group of adventurers called the “Sign of One” who believe that each of them, individually, have the power to shape the universe with their minds. That’s a “Signer” in the illustration above.)
Criticisms of Facebook include the notion that it encourages users to be self-absorbed, or to surround themselves with like-minded people who reiterate similar opinions, like what happened in the George W. Bush administration. In that sense, maybe Facebook is turning us into solipsists.
But I’m inclined to think Facebook promotes the opposite of solipsism — whatever that is. As you grow accustomed to putting every passing thought, announcement, and photo online for your friends to witness and validate, you start to feel like nothing in your life really exists until it’s been reflected by an Other.
