The book deals with a central question for the understanding of reality and the way in which human beings relate to it. Humans are creatures that can deliberate and define their actions by virtue of deliberation. He who deliberates relates himself to elements of reality that speak for or against doing something, and that in some mysterious way require him to act in a certain fashion. This book investigates this normative reality and its ontology. There is no normativity in reality independent from us. How does it then come to be in the world? What are the conditions of its existence?
