Inefficient Unanimity

ABSTRACT The notion of consensus plays an important epistemological role in modern welfare economics, in that unanimous consent is a (unique) conceptual test for those changes that are 'Pareto-desirable' (that is, make someone better off and no-one else worse). In this paper, we seek to show that unanimous consent does not logically imply Pareto-desirability—that a rational individual may fail to veto policy changes that make him/her worse off. The central element in the proof of this proposition is the observation that in social agreements involving a significant number of participants, any one individual's veto is decisive if it is the only veto. If the individual does not expect to be decisive, he will rationally exercise his vote 'expressively', and without sole regard to its consequences. When all individuals so act, a sort of prisoners' dilemma interaction may emerge, even under explicit consensus.     

CIPHERS OF TRANSCENDENCE: COGNITIVE AESTHETICS IN SCIENCE

Modern epistemology is reluctant to presume the objectivity of a mental event. Because a valid theory of knowledge is subjected to objective standards of rationality, the invocation of a transcendent ground of existence termed ‘god’ is deemed extra‐systematic. This reference lacks warrant because it fails to satisfy the impartial criteria methodologically basic to contemporary paradigms of knowledge. Still the biochemist Arthur Peacocke (1924–2006) claimed defensible public truth for an ultimate reality based on the ‘supremely’ rational nature of existence; it is the further contention of this paper that there are intelligible patterns to the universe whose discovery is incapable of ‘objective’ explanation. By failing to meet these criteria, however, they do not fall into irrationality, still less do they disqualify or exclude themselves from public consideration; quite the opposite. There are perhaps depths to human experience then, including science, to which an existentialist epistemology is appropriate. In this connection the philosophy of Karl Jaspers (1883–1969) provides a compelling account of the transition of scientific research into aesthetics and theological discourse.
