The paper gives a new light on the controversy between Popper and Carnap on the interpretation of probability and its use to solve the problem of induction. In his later work on probability and inductive logic, Carnap came nearer to the bayesian positions stressing an important shift from his ear..
We generalize two classical results on cylindric algebra to certain expansions of cylindric algebras where the extra operations are defined via first order formulas. The first result is the Neat Embedding Theorem of Henkin and the second is Monk's classical non-finitizability result of the class of representable algebras. As a corollary we obtain known classical results of Johnson and Biro published in the Journal of Symbolic logic.
I discuss two subjects in Samir Okasha’s excellent book, Evolution and the Levels of Selection. In consonance with Okasha’s critique of the conventionalist view of the units of selection problem, I argue that conventionalists have not attended to what realists mean by group, individual, and genic selection. In connection with Okasha’s discussion of the Price equation and contextual analysis, I discuss whether the existence of these two quantitative frameworks is a challenge to realism.
Evolution and Rationality marks the end of a three-year project, ‘Evolution, Cooperation, and Rationality’, directed at the University of Bristol by the book’s editors, Samir Okasha and Ken Binmore. The collection draws together the editors’ pick of the papers delivered at the conferences the project hosted, and covers a wide range of topics at the intersection of evolutionary theory and the social sciences. It is a splendid anthology: timely, interdisciplinary, thematically cohesive, and full of substantive and interesting disagreements between (...) the contributors. (shrink)
After a thorough examination of the claim that "the underdetermination of theory by evidence forces us to seek sociological explanations of scientists' cognitive choices", Samir Okasha concludes that the only significant problem with this argument is that the thesis of underdetermination is not adequately supported. Against Okasha, I argue (1) that there is a very good reason to question the inference from the underdetermination of a theory to a sociological account of that theory's acceptance, and (2) that Okasha's own (...) objection to the argument is too weak.

This paper attempts to deepen the already rich exchange between Caribbean scholars and the distinguished African scholar Samir Amin. In particular, it attempts to expand the exchanges on the relations between philosophy, economics and culture. The expansion uncovers hidden but significant complementary relations between the contributions of Caribbean scholars, such as C.L.R. James, Lloyd Best, and Sylvia Wynter, and the work of Amin on philosophy economics and culture.
The use of networks as an explanatory framework is widespread in the literature that surrounds technology and information society. The three books reviewed here — The Wealth of Networks by Yochai Benkler, Decoding Liberation: The Promise of Free and Open Source Software by Samir Chopra and Scott Dexter, and The Exploit: A Theory of Networks by Alexander Galloway and Eugene Thacker — all make a claim to the novelty that networks provide to their subject matter. By looking closely at (...) the way in which the network is utilized in each of the texts, this review attempts to question the extent to which a network analysis can ground a claim about a discontinuity in technology, society or economics.

The debate about the levels of selection has been one of the most controversial both in evolutionary biology and in philosophy of science. Okasha’s book makes the sort of contribution that simply will not be able to be ignored by anyone interested in this field for many years to come. However, my interest here is in highlighting some examples of how Okasha goes about discussing his material to suggest that his book is part of an increasingly interesting trend that sees (...) scientists and philosophers coming together to build a broadened concept of “theory” through a combination of standard mathematical treatments and conceptual analyses. Given the often contentious history of the relationship between philosophy and science, such trend cannot but be welcome. (shrink)
