Popular interest in bullshit - and its near relative, truthiness - is at an all-time high, but the subject has a rich philosophical history, with Hobbes, Locke, Hume, and Kant all weighing in on the matter. Here, contemporary philosophers reflect on bullshit from epistemological, ethical, metaphysical, historical, and political points of view. Tackling questions including what is bullshit, what does it do, is it a passing fad, and can it ever be eliminated, the book is a guide and resource for the many who find bullshit worth pondering.
