Responsibility Without Awareness

Unlike most other discussions of responsibility, which focus on the idea that to be responsible, agents must in some sense act voluntarily, this book focuses on the relatively neglected idea that they must in some sense know what they are doing. Because it integrates first-and-third personal elements, this account is well suited to capture the complexity of responsible agents, who at once have their own private perspectives and live in a public world.
