Ecological rationality is a concept important to most environmental and natural resources policy and to much policy-relevant literature and research. Yet ecological rationality as a distinctive form of reason can only be understood and appreciated in the context of a larger body of work on the general concept of rationality. In particular, Herbert Simon’s differentiation between substantive and proceduralrationality and Paul Diesing’s specification of forms of practical reason are useful tools in mapping and defining ecological rationality. The significance and characteristics of ecological rationality suggest that it is a fundamental kind of reason, having precedence over others.

The literature on theoretical reason has been dominated by epistemological concerns, treatments of practical reason by ethical concerns. This book overcomes the limitations of dealing with each separately. It sets out a comprehensive theory of rationality applicable to both practical and theoretical reason. In both domains, Audi explains how experience grounds rationality, delineates the structure of central elements, and attacks the egocentric conception of rationality. He establishes the rationality of altruism and thereby supports major moral principles. The concluding part describes the pluralism and relativity his conception of rationality accommodates and, taking the unified account of theoretical and practical rationality in that light, constructs a theory of global rationality--the overall rationality of persons. Rich in narrative examples, intriguing analogies, and intuitively appealing arguments, this beautifully crafted book will spur advances in ethics and epistemology as well in philosophy of mind and action and the theory of rationality itself.

Feyerabend's views are construed as formulating the problem of determining the role of rhetoric in scientific rationality and posing the solution-theory that scientific rationality is essentially rhetorical. He is taken to give three arguments against reason, of which the one from the insufficiency of reason and the one from incommensurability are shown to presuppose his historical argument; his historical argument is based on his account of Galileo, which hinges essentially on Feyerabend's analysis of the tower argument. This analysis is insightful in certain important ways but misconceived in others. Feyerabend's main error is to see a conflict between reason and rhetoric, where none exists; it is argued that rhetorical devices have their own standards of propriety and impropriety, different from those of rational arguments, and that at the same time sound rhetorical analysis presupposes sound logical analysis.

Ethical dualists hold that we have good reason to pursue our own happiness and good reason to pursue moral goodness. It would seem that there is a potential conflict here. On the other hand there have been those who deny even the possibility of conflict, whether or not there is a God and an afterlife. Rawls seems to say, or hint, that this was Butlers’ view, and Kant, according to at least one person, argued that there cannot be conflict here. I think the conflict is sometimes real, and that ‘practical reason’ does not resolve it.

Ethical dualists hold that we have good reason to pursue our own happiness and good reason to pursue moral goodness. It would seem that there is a potential conflict here. On the other hand there have been those who deny even the possibility of conflict, whether or not there is a God and an afterlife. Rawls seems to say, or hint, that this was Butlers’ view, and Kant, according to at least one person, argued that there cannot be conflict here.

Rationality and reasonableness are often sharply distinguished from one another and are even held to be in conflict. On this construal, rationality consists in means-end calculation of the most efficient means to one's ends (which are usually taken to be self-interested), while reasonableness consists in equitableness whereby one respects the rights of other persons as well as oneself. To deal with this conflict, it is noted that both rationality and reasonableness are based on reason, which is analyzed as the power of attaining truth, and especially necessary truth. It is then shown that, by the rationality involved in reason, the moral principle of reasonableness, the Principle of Generic Consistency (PGC), has a stringently rational justification in that to deny or violate it is to incur self-contradiction. Objections are considered bearing on relevance and motivation. It is concluded that, where reasonableness and egoistic rationality conflict, the former is rationally superior.

The title of Emmanuel Eze’s final, posthumously published book uses the words “reason” and “rationality” in a manner that might suggest they are interchangeable. I would like to suggest that we not treat them as the same, but rather tease out a difference in emphasis and reference between the two. In African philosophy, the problem of reason is really two separate problems, the first of which I will call the “problem of reason” (that is, the question of whether there are diverse forms of reason or only one universal form) and the second the “problem of rationality” (that is, the question of whether everyone has the capacity to deploy reason past what mimicry or programming makes possible). Both of these problems are addressed by Eze’s schema for forms of reason. He identifies several forms, but focuses on “ordinary reason”, which allows all the other forms to operate. Ordinary reason also makes rationality possible, that is, the culturally specific yet emergent way of navigating forms of reason. Reason is necessarily diverse, because its multiple forms are deployed differently by different rationalities.
