This dissertation addresses a debate about the proper relationship between democratic theory and institutions. The debate has been waged between two rival approaches: on the one side is an aggregative and economic theory of democracy, known as constitutional economics, and on the other side is deliberative democracy. The two sides endorse starkly different positions on the issue of what makes a democracy legitimate and stable within an institutional setting. Constitutional economists model political agents in the same way that neoclassical economists (...) model economic agents, that is, as self-regarding, rational maximizers; so that evaluations of democratic legitimacy and stability depend on the extent to which the design of institutional rules and practices maximize individual utility by promoting efficient schemes of collective choice. Deliberative democrats, on the other hand, understand political agents as communicative reason-giving subjects who justify their preferences and positions on issues that jointly affect them in a process of consensus-directed discourse, or deliberation; so that evaluations of democratic legitimacy and order depend on the degree to which institutional norms and practices promote deliberation and draw upon deliberated public judgment. I argue that despite the numerous incompatibilities between constitutional economics and deliberative democracy—which amount to a 'deep divide'—an opportunity to produce a genuine synthesis of the two approaches arises inasmuch as it is possible to overcome several points of opposition in their separate research programmes. The central thesis of the dissertation is that it is possible to construct a bridge spanning the divide between constitutional economists and deliberative democrats, and that Dewey and Bentley's transactional view can facilitate this bridge-building project. Pursuant to this end, the points of opposition between the v research programmes are mediated by way of five concepts which, on balance, favor deliberative democracy and its feasible institutionalization.

In recent years, several authors have debated about the justifiability of so-called scientific imperialism. To date, however, widespread disagreements remain regarding both the identification and the normative evaluation of scientific imperialism. In this paper, I aim to remedy this situation by making some conceptual distinctions concerning scientific imperialism and by providing a detailed assessment of the most prominent objections to it. I shall argue that these objections provide a valuable basis for opposing some instances of scientific imperialism, but do not (...) yield cogent reasons to think that scientific imperialism in general is objectionable or unjustified. I then highlight three wide-ranging implications of this result for the ongoing philosophical debate about the justifiability of scientific imperialism. (shrink)

Prospect theory is an alternative theory of choice under conditions of risk, and deviates from expected utility theory by positing that people evaluate choices with respect to gains and losses from a reference point. They tend to overweight losses with respect to comparable gains and engage in risk-averse behavior with respect to gains and risk-acceptant behavior with respect to losses. They also respond to probabilities in a non-linear manner. I begin with an overview of prospect theory and some of the (...) evidence upon which it is based, and then consider some of the implications of the theory for American politics, international relations, and the law. I end with a brief discussion of some of the conceptual and methodological problems confronting the application of prospect theory to the study of politics. (shrink)

The thesis contrasts two hostile and divergent intellectual paradigms in social sciences: rational choice and critical theory. Both rational choice and critical theory offer contrasting perspectives on the structures of social interaction. However, both critical theory and rational choice theory share overlapping concerns ie., both are preoccupied with determining what rational can mean in the realm of social and political interaction. In the case of rational choice paradigm, instrumental reason forms the cornerstone of the theoretical edifice. Ever since the publication (...) of Jurgen Habermas' The lhemy qf Communicative Action Vol. / and Vol. II instrumental reason has come under severe attack. His critique anchors on a theory of communicative reason. What makes Habermas' work distinctive is that he does not regard instrumental reason as the single inevitable concomitant of modernity. Habermas sees in modernity an alternative way of conceptualising social interaction in terms of communication rather than strategy. So in a way, his work is a challenge to the defenders of modernity aiming to build a unified social science Jurgen Habermas advances the notion of communicative reason as the centerpiece of a social theory as opposed to instrumental reason. By providing a systematic grounding of the concept of reason in human language, he hopes to establish normative basis of critical theory. This model of reaching agreement or consent constitutes a process of dialogue in which reasons are exchanged between participants. This process is perceived to be a joint search for consensus. Such a dialogic concept of collective choice would necessarily work not with fixed preferences to be amalgamated but with preferences that are altered or modified as competing reasons are advanced in the course of discussion. In rational discussion, the only thing supposed to count is the power of better argument. Both rational choice and critical theory conceptualise politics in different ways. Rational choice theories critique democratic mechanisms failing to generate general will. Consequently, the political prescriptions offered are limited government or market. On the contrary, the political implications of Habermas' theory of deliberative democracy is anchored in the notion of liberal public sphere envisaging a cognitivist, rationalist vision in which discourse forms a critical normative basis for evaluating the political and moral principles.

Drawing general inferences on the basis of single-case and small- n studies is often seen as problematic. This article suggests a logic of generalization based on thinly rationalistic social mechanisms. Ideal-type mechanisms can be derived from empirical observations in one case and, based on the assumption of thin rationality, used as a generalizing bridge to other contexts with similar actor constellations. Thus, the “portability” builds on expectations about similar mechanisms operating in similar contexts. We present the general logic behind such (...) “rationalistic generalization” and relate it to other ideas about generalization from single-case studies. (shrink)
