Sommario/riassunto |
|
In re-examining the concepts of desire, intention, and trying, David K. Chan brings a fresh approach toward resolving many of the problems that have occupied philosophers of action for almost a century. This book not only presents a complete theory of human agency but also, by developing the conceptual tools needed to do moral philosophy, lays the groundwork for formulating an ethics that is rooted in a clear, intuitive, and coherent moral psychology. |
