Often without thinking about it, people constantly differentiate: whether it's warm or cold, whether they can smell someone else, whether something fits them or not. These differences create sensations on their own, but they are fueled by experiences rooted in the millions of years of human evolution. The incessantly active faculty of discrimination, which subtly shapes personal and societal relationships, is referred to by Alexander Kluge as his domain. He advocates for the mass production of discernment. In his opening balance sheet of the 21st century, the Chronicle of Feelings, he has begun an inventory of emotional resources. In this book, he explains the origins of his skepticism towards the factual, what drives him to track down feelings and sensations, and how to unmask them as destructive secret agents.
