Lars Gustafsson takes us on a journey in his last book, which is now being published posthumously, into the borderland between philosophy of language, logic, and theory of meaning, ultimately leading to profound existential questions. Are there things beyond what can be said, about which we can no longer speak? What is the significance of nothingness? What does it mean to not exist? Does the meaningless have significance? What is truth, what is a lie, and how do they differ? Do dreams exist, or only dream narratives? Is every dreamer a poet? Starting from the wonder at the once incredibly fast communication method of the optical telegraph, the thoughts of this universally educated individual, who is equally versed in the sciences, philosophy, and literature, revolve around the possibility of connecting mathematical structures for language and poetry with approaches from the theory of meaning.
