"Hooker brings a depth and breadth of vision to the standard issues in his field that far surpass any of his competitors, even the few who have larger reputations. Anyone who reads this book will have his conception of the field permanently changed." — Paul M. Churchland"Hooker presents a unified and powerful argument for realism, taking into account the major recent critiques of this position. Hooker also develops this view, and its consequences for philosophy of science, epistemology, science policy, and social and political philosophy to a degree that no one else has approached." — Harold I. Brown
