Frege's Planet

Frege's Planet is a thought experiment inspired by the philosopher Gottlob Frege's ideas about language and meaning. It imagines a world where the only inhabitants are aliens who possess a language but lack any clear reference to objects in reality. They can express thoughts, but without a shared understanding of what those thoughts relate to in the real world. This concept illustrates the distinction between meaning and reference in language, highlighting how communication relies on both the structure of language and the shared understanding of what words signify in our world.
