Do individuals have a positive right of self-defense? And if so, what are the limits of this right? Under what conditions, if any, does this use of force extend to the defense of others? These are some of the issues explored by Dr. Uniacke in this comprehensive philosophical discussion of the principles relevant to self-defense as a moral and legal justification for homicide. This is a lucid and sophisticated account of the complex notion of justification, revolving around a critical discussion of recent trends in the law of self-defense.
