In Return to Reason, Stephen Toulmin sums up a lifetime's work in rescuing the reasonableness of ordinary practices from the oblivion to which they are consigned when we equate reason with abstract theory alone. From the knack of a wordless skill, to the work of really good professionals, he shows us how situated practice is central in real life. His critique applies to Modernism and Postmodernism alike and offers a true guide to those of us perplexed by the theoretical idols of the day.

In an elegant and wide-ranging investigation through history and philosophy, Stephen Toulmin challenges the wide-spread, modern misapplications of scientific "rationality" beyond its proper bounds. He shows how the parallel recourse to "reasonableness," properly re-instituted, can help us master real-life tasks, with both cool heads and warm hearts.

Stephen Toulmin speaks eloquently for the genius of ordinary life. Like Montaigne and Wittgenstein, he favors thinking that is practical and particular, not vacuous and formal. His book is an antidote and a warning: it is thoughtful, perceptive engagement, not theory, that allays personal and social problems. Human sciences describe our circumstances; they cannot prescribe solutions. Ideologists will resist. Dewey would cheer.

In elegant prose, Toulmin...contends that advocates of pure reason have forgotten "the complementary concept of reasonableness," a model of intellectual practice focused on values and experience rather than facts and theories. His rich conceptual history outlines the ways in which early modern science and philosophy separated reasonableness from rationality, and the resulting imbalance in all academic disciplines.

Toulmin shows in this readable and fascinating account, the practice of reason that produced modern science goes back to the 17th century, when traditional reasonableness was replaced by the model of geometry...Eventually--and this is perhaps one of Toulmin's most challenging insights--what came of this change is the system of disciplines that govern modern intellectual life...Throughout Return to Reason, Toulmin calmly addresses complex situations arising in modern disciplines. Indeed, the knack he shows for reasonableness illustrates his thesis. His book is both a diagnosis and, by example, a cure for what ails our scientific culture.

There is now a 'loss of confidence'...in our traditional ideas about rationality, according to Toulmin. Especially among those in the humanities, he argues, the claims of rationality have been progressively challenged over the last 20 or 30 years, to the point of being sidelined. This is a common complaint and not exactly news, but Toulmin does not merely bemoan and rant, as many others have done. He offers a diagnosis and a solution. Rationality has come under threat, he believes, because of the undue influence of classical mechanics and abstract mathematical methods on our idea of what intelligent problem-solving should be. Deduction in the style of Euclid's geometry, mechanically predictable and rigorous law in the style of Galileo and Newton, indubitable certainty in the style of Descartes' 'I think, therefore I am' all exert a malign influence, insofar as they overshadow a looser, more pragmatic and less abstract concept of 'reasonableness.' What we need is more open-minded, informal reasonableness and less inappropriately mathematical rationality. Only then, Toulmin argues, can the idea of reason regain its rightful good name.

In this mature work, Toulmin...sums up a distinguished scholarly career spent tenaciously pursuing this and related questions. He adroitly integrates the arguments from his previous works...in a broad, humanistic vision of how to restore the balance of reason maintained in Greek antiquity...Toulmin employs a rich array of examples and accessible prose...Recommended.

The argument in the book is wide-ranging and fluently expressed...Toulmin has taken on board arguments presented in debate by experienced practitioners, such as in the account of development economists and the water systems in Bali, his favorite vignette to illustrate the situatedness of economic relations. He ranges across the disciplines from astronomy to international relations, with a concern for professions, government policy making and the role of NGOs.
