Given the increasing centrality of identity to contemporary politics, James Skelly’s book provides a critical and useful analysis of the dominant and problematic conceptual bases for self and identity. Inspired in part by his lawsuit against the US Secretary of Defense while serving as an active duty military officer, Skelly argues that our use of language in the construction of identities is unwitting, unreflective, and has engendered horrific consequences for tens of millions of humans. In contrast, he demonstrates our need to overcome sectarian modes of thinking and to engage in much deeper forms of solidarity with others by foregrounding a species identity. This book offers not only an academic reflection on the concept of identity but one that delves into the nature of the self and identity by drawing on Skelly's concrete experience of attempting to present a self-identity opposed to war in the face of the political, psychological, religious, and legal arguments put forth in a year-long legal battle with the United States government. One consequence is that Skelly argues that to create a new and more pacific human sensibility we must help ourselves and others to gain sovereignty over our social worlds and the definition of 'who we are', by arming individuals with the tools necessary to overcome the definitions and categorisations we are subjected to in the construction of traditional notions of 'identity'.
