How did we find ourselves in a "post-truth" world of "alternative facts"? And can we get out of it? This book sets out to answer these questions by looking at the complex history of truth and falsehood. It identifies ten types of supposed truth and explains how easily each can become the midwife of falsehood. There is no species of truth that we can rely on unquestioningly, but that does not mean the truth can never be established. The thinking person's tonic for our troubling times.
