For many, aliens only exist in the realm of science fiction. But regardless of whether aliens exist or not, the potential existence of extraterrestrial species throws into question our entire metaphysical framework, which has long gone unchallenged. In particular, we would need to rethink our understanding of language, which currently determines how we experience our world.

But what if there were other languages out there that better captured reality? For theoretical philosopher Matti Eklund, these are the questions philosophy needs to be asking.

“Investigating what alien languages there can be is a natural and fruitful way to investigate different ways for the world to be,” Eklund argues.
