Defiendo la legitimidad de la pregunta acerca de cuál puede ser el estatuto cognitivo de la Teoría Económica, y sostengo que la Teoría se comprende mejor como una rama de la Filosofía Política formal, en concreto, como una especie de contractualismo. Esto parece particularmente adecuado corno explicación de la Teoría deI equilibrio general. Dado el carácter intencional de las variables explicativas de la Teoría Económica y el papel de la información al realizar una elección, se argumenta que es improbable que dicha Teoría pueda garantizar el poder predictivo, que le permitiría funcionar corno teoría factual en vez de corno teoría normativa.I defend the integrity of the question of what the cognitive status of economic theory could amount to, and I argue that the theory is best understood as a compartment of formal political philosophy, in particular a species of contractarianism. This seems particularly apt as an account of general equilibrium theory. Given the intentional character of the explanatory variables of economic theory and the role of information in effecting choice, it is argued that economic theory is unlikely to secure the predictive power that would enable it to function as a factual instead of a normative theory

The diversity, complexity and adaptation of the biological realm is evident. Until Darwin, the best explanation for these three features of the biological was the conclusion of the “argument from design.” Darwin's theory of natural selection provides an explanation of all three of these features of the biological realm without adverting to some mysterious designing entity. But this explanation's success turns on the meaning of its central explanatory concept, ‘fitness’. Moreover, since Darwinian theory provides the resources for a purely causal account of teleology, wherever it is manifested, its reliance on the concept of ‘fitness’ makes it imperative that conceptual problems threatening the explanatory legitimacy of this notion be solved.

I have argued not that economics has no predictive content, but that it is limited, or at least has so far been limited to generic predictions. Now this is an important kind of prediction, and almost certainly a necessary preliminary to specific or quantitative predictions. But if the sketch of an important episode in the twentieth century history of the subject I have given is both correct and representative, then economics seems pretty well stuck at the level of generic prediction. And at least some influential economists and philosophers of economics seem well satisfied with stopping at the point of generic prediction. Or at least they give no other reason than its power to produce such predictions as a justification for the character of economic theory. But this leads to the question that is the title of my paper, is generic prediction enough?

In this paper the concept of supervenience is employed to explain the relationship between fitness as employed in the theory of natural selection and population biology and the physical, behavioral and ecological properties of organisms that are the subjects of lower level theories in the life sciences. The aim of this analysis is to account simultaneously for the fact that the theory of natural selection is a synthetic body of empirical claims, and for the fact that it continues to be misconstrued, even by biologists, for a tautological system. The notion of supervenience is then employed to provide a new statement of the relation of Mendelian predicates to molecular ones in order to provide for the commensurability and potential reducibility of Mendelian to molecular genetics in a way that circumvents the theoretical complications which appear to stand in the way of such a reduction

In "Events and Causality" Mark Steiner argues that though Bertrand Russell was right to claim that the laws of physics do not express causal relations, nevertheless, Russell was wrong to suppose that therefore causality plays no role in physics. I argue that Steiner misses the point of Russell's argument for the first of these claims, and because of this Steiner's argument against the second fails to controvert it. Steiner fails to see that Russell's argument against causation, is in fact an argument against the existence of causal directionality or asymmetry. Steiner gives no reason to suppose physical theory requires this asymmetry after all

The prescriptive force of methodological rules rests, I argue, on the acceptance of scientific theories; that of the most general methodological rules rests on theories in the philosophy of science, which differ from theories in the several sciences only in generality and abstraction. I illustrate these claims by reference to methodological disputes in social science and among philosophers of science. My conclusions substantiate those of Laudan except that I argue for the existence of transtheoretical goals common to all scientists and concrete enough actually to have bearing on methodology. And I argue that Laudan is committed to such goals himself, willy nilly

Many realists have maintained that the success of scientific theories can be explained only if they may be regarded as approximately true. Laurens Laudan has in turn contended that a necessary condition for a theory's being approximately true is that its central terms refer, and since many successful theories of the past have employed central terms which we now understand to be non-referential, realism cannot explain their success. The present paper argues that a realist can adopt a view of reference according to which a theory might plausibly be said to be approximately true even though its central terms do not refer, or alternatively, he may construe reference in such a way as to assign reference to a range of successful older theories which includes Laudan's purported counterexamples

The underdetermination of theory by evidence must be distinguished from holism. The latter is a doctrine about the testing of scientific hypotheses; the former is a thesis about empirically adequate logically incompatible global theories or "systems of the world". The distinction is crucial for an adequate assessment of the underdetermination thesis. The paper shows how some treatments of underdetermination are vitiated by failure to observe this distinction, and identifies some necessary conditions for the existence of multiple empirically equivalent global theories. We consider how empiricists should respond to the possibility of such systems of the world

We raise three issues for Philip Kitcher's "Ethical Project" (2011): First, we argue that the genealogy of morals starts well before the advent of altruism-failures and the need to remedy them, which Kitcher dates at about 50K years ago. Second, we challenge the likelihood of long term moral progress of the sort Kitcher requires to establish objectivity while circumventing Hume's challenge to avoid trying to derive normative conclusions from positive ones--'ought' from 'is'. Third, we sketch ways in which Kitcher's metaethical opponents could respond to his arguments against them.

That biology provides explanations is not open to doubt. But how it does so must be a vexed question for those who deny that biology embodies laws or other generalizations with the sort of explanatory force that the philosophy of science recognizes. The most common response to this problem has involved redefining law so that those grammatically general statements which biologists invoke in explanations can be counted as laws. But this terminological innovation cannot identify the source of biology's explanatory power. I argue that because biological science is historical, the problem of biological explanation can be assimilated to the parallel problem in the philosophy of history, and that the problem was solved by Carl Hempel. All we need to do is recognize that the only laws that biology—in all its compartments from the molecular onward—has or needs are the laws of natural selection.

Eliminativism about intentional content argues for its conclusion from the partial correctness of all three of the theses Hutto and Satne seek to combine: neo-Cartesianism is correct to this extent: if there is intentional content it must originally be mental. Neo-Behaviorism is correct to this extent: attribution of intentional content is basically a heuristic device for predicting the behavior of higher vertebrates. Neo-Pragmatism is right to this extent: the illusion of intentionality in language is the source of the illusion of intentionality in thought. Eliminativists employ the insights of all three “neo”-theses to explain why there is no such thing and why the systematic illusion that there is intentional content runs so deep
