Philosophers have defended many different views on what reality is like. But despite their differences, the views share the same basic structure. The world is basically a world of objects, having properties and standing in relations. This structure mirrors the structure of basic sentences of the languages we use. But what other kinds of languages can there be? And might the world be such that another kind of language best represents it? That is, can there be alien languages and alien metaphysical structure? This book sharpens these claims, and defends the possibility of alien languages and alien metaphysical structure. The book raises novel questions going to the heart of language and metaphysics, sharpens them, and proposes radical answers. Along the way, it discusses different kinds of work in contemporary philosophy of language, linguistics and metaphysics and the relevance of this work to the topic of the alien.
