The book links the concept of intention to human action. It provides answers to questions like: Why do we act intentionally? Which impact do reasons and motives have on our decisions? Certain events are identified as intentional actions when they are considered as being rationalized by reasons. The linguistic description of such events enables us to reveal the structure of intention. The mental and the linguistic constitute irreducible ways of understanding events. Among the topics discussed are intentionality, actions, the linguistic form to talk about intentionality and actions, Brentanos view of intentionality, the phenomenological approach to intention and Wittgenstein's proposals. The contributions by Wolfgang Künne, Peter Simons, Christian Bermes, Kevin Mulligan, Severin Schroeder, António Marques, Margit Gaffal, Michel Le Du, Jesús Padilla Gálvez, Bernhard Obsieger and Amir Horowitz show that actions and decisions are guided by intentional considerations.
