"Monadology" by Gottfried Wilhelm Leibniz is a fundamental treatise of philosophy, which reveals to the reader a deep doctrine about monads, which are the main substances of the universe. In this book, Leibniz reveals his unique concepts about the nature and structure of monads, as well as important theoretical propositions about interaction and perception. In an additional chapter to this book, the author also examines Herbart's theories about real events, compares them with Leibniz's own views, and offers the reader new ways of understanding the nature of life and being. Leibnitz' Monadologie Deutsch mit einer Abhandlung über Leibnitz' und Herbart's Theorien des wirklichen Geschehens is not only a philosophical work, but also an invitation to deep and thoughtful reflection on the nature of the universe and man in it.
