A feature of this book is the broad range of the contributors, drawn from Europe, the Middle East and North America, testifying both to the range of Professor Agassi’s interests and the geographical spread of his influence. Most contributors use Agassi’s ideas as a springboard to engage in debate on issues, or offer a contribution in an area that interests him. In this volume contributors consider such questions as: Agassi’s philosophy of education, in practice as well as in theory; the impact of psychology on philosophy; the origins of critical rationalism in the Bible; and the debates in economics stimulated by the work of Popper and Agassi. Besides the special topics, the reader should gain some sense of the fruitfulness of critical rationalism in the hands of Agassi’s friends and colleagues.
