Book excerpt: Philosophers increasingly engage in practical work with other disciplines and the world at large. This volume draws together the lessons learned from this work—including philosophers’ contributions to scientific research projects, consultations on matters of policy, and expertise provided to government agencies and non-profits—on how to effectively practice philosophy. Its 22 case studies are organized into five sections: I Collaboration and Communication II Policymaking and the Public Sphere III Fieldwork in the Academy IV Fieldwork in the Professions V Changing Philosophical Practice Together, these essays provide a practical, how-to guide for doing philosophy in the field—how to find problems that can benefit from philosophical contributions, effectively collaborate with other professionals and community members, make fieldwork a positive part of a philosophical career, and anticipate and negotiate the sorts of unanticipated problems that crop up in direct public engagement. Key features: Gives specific advice on how to integrate philosophy with outside groups. Offers examples from working with the public and private sectors, community organizations, and academic groups. Provides lessons learned, often summarized at the end of chapters, for how to practice philosophy in the field.
