This book details opposing scientific claims about the hazard identification of modern biotechnology. Offered are remedies to frustrating stalemates in the debate that trace back the conflicting biosafety claims to their experimental basis. The purpose of biosafety testing is to identify possible hazards in the use of genetically engineered organisms. Presented is an applied philosophy of science that focuses on finding relevant questions. The potential of this pragmatic viewpoint is demonstrated in the reconstructions of a number of longstanding controversies in the biotechnology debate.
