...Sloterdijk initially planned to write a celebration paper on Assmann. Structured into two parts, the book sets out to bring together a number of theological-philosophical-literary themes, on the basis of which the author presents, in a philosophical manner, the concept of theopoetics or on religion as poetry, as Robert Hughes explanatorily translates the concept of die Theopoesie. ...the problem of the "unspoken", of the supernal other, of heaven, is rendered into words, into poetry, because it is only through speech that we are brought face to face with the irrational and thus able to bring "heaven" into the world, in a language we can understand. The discussion that follows in this book will concern primarily communicative, bright heavens inviting uplift, because, in accord with the task of poetic enlightenment, the heavens constitute the common provenance of gods, verse, and the uplifting of spirits (2023, XII). ...the problem of transposing the heavens as communicative "images" is caused by man's inability to perceive the heavens in their essence, as Sloterdijk states: "the heavens that can be made to speak are not a possible object of visual perception" (2023, XI). ...just as through singing the higher powers reach man's ear, so does through speech heaven reaches man's language. ...cathedrals would be fables written in hard stone; priests would be actors absorbed in their roles; martyrs would be sorcerers' apprentices who never return from their journeys into the hereafter; theologians would be dramaturges who deal with the grammar of fables (2023, 44). According to Sloterdijk (2023, 44), they describe an innate pre-programming of the human brain, also called the religious brain, that produces beliefs regarding the presence of forces, of "supernatural agents" (Boyer 2001, 16). ...this sensitivity to transcendence is merely a natural faculty of the human brain to think of the existence of highly intelligent structures.
