Theories of explanation in the social sciences vacillate between holism and individualism. Wettersten contends that this has been a consequence of theories of rationality which assume that rationality requires coherent theories to be shown to be true. Rejecting these traditional assumptions about rationality Wettersten claims that the traditional explanations of rationality have placed unrealistic demands on both individuals and institutions. Analysing the theories of Weber and Popper, Wettersten shows that Popper made considerable progress in the theory of rationality, but ultimately stayed too close to the ideas of Hayek, he explains how this dilemma leads to difficulties in economics, anthropology, sociology, ethics and political theory, and constructs an alternative theory that rationality is critical problem-solving in institutional contexts. Wettersten contends that 'the critical consideration of theories followed by their improvement' dispenses with the need for justification and sees rationality as a social phenomena with an institutional basis. The main social advantages this view offers is that the degree of rationality individuals achieve may be increased by institutional reform without moralizing and that we can explain how institutions steer events insofar as we understand how they determine the problems which individuals seek to solve. It is argued that the central moral advantage of this view is that rationality is shown to be Spinozistic in the sense that it is natural and furthers morality and peace of mind.

'A glance at the literature in the social sciences will show that quite generally the role of institutions in decision making processes is central. Despite the proliferation of the literature on detailed cases there are hardly any studies of it in general. in the philosophy of the social sciences this is where the action is. Wettersten's book is an important contribution to this study and its impact might very well extend to well beyond philosophy.'
