"This work is an important monograph on the thought of Karl Popper. It identifies objectivity as a core problematic in contemporary philosophy and traces Popper's unique approach to this issue. In an original contribution to Popper scholarship, the author argues that Popper's response to the problem of demarcating critical thinking from dogmatic thinking yields an account of objectivity that unites empiricism and metaphysics and can help explain the growth of knowledge. Non-technical, but logically rigorous presentations of probability logic, the problem of verisimilitude, and evolutionary epistemology contribute to an accessible text that belongs in any philosophy of science collection. Moreover, the centrality of objectivity to contemporary philosophical discourse establishes this book as relevant to a broad philosophical audience." Richard J.
