Abstract
Contact optimists have tended to assume that alien messages would be relatively easy to understand. The communication of quite complicated information is not very difficult, claimed Sagan, even for civilizations with very different biologies and social conventions. Once pictures are transmitted, it will be extremely simple to develop language—by show and tell.3
