How do ordinary people come to know or believe what they do? We need an account of this process to help explain why people act as they do. You might think I am acting irrationally--against my interest or my purpose--until you realize that what you know and what I know differ significantly. My actions, given my knowledge, might make eminently good sense. Of course, this pushes our problem back one stage to assess why someone knows or believes what they do. That is the focus of this book. Russell Hardin supposes that people are not usually going to act knowingly against their interests or other purposes. To try to understand how they have come to their knowledge or beliefs is therefore to be charitable in assessing their rationality. Hardin insists on such a charitable stance in the effort to understand others and their sometimes objectively perverse actions. Hardin presents an essentially economic account of what an individual can come to know and then applies this account to many areas of ordinary life: political participation, religious beliefs, popular knowledge of science, liberalism, culture, extremism, moral beliefs, and institutional knowledge. All of these can be enlightened by the supposition that people are attempting reasonable actions under the severe constraints of acquiring better knowledge when they face demands that far outstretch their possibilities.

This book develops a general, economic theory of ordinary knowledge and applies it to many different kinds of knowledge and belief, providing a clear and convincing view of many of the world's problems, such as fanaticism and nationalism. A significant contribution that will be useful to readers in many different fields, How Do You Know? is also beautifully written and a pleasure to read. -- Jonathan Baron, University of Pennsylvania Russell Hardin's How Do You Know? is original, thought provoking, and important. It raises questions of both practical and intellectual significance and it is very well written--indeed, it is an engrossing read. -- Geoffrey Brennan, Duke University and University of North Carolina, Chapel Hill
