The movement for the Unity of Science has been making headway for a number of years, and each year more workers in the various scientific domains have expressed their interest in it by participating in the discussion of its aims and its specific problems. A characteristic feature of this movement which explains this growing interest is that it does not propose a “super-science” which is to legislate to the special sciences. Its proposal of a Unity of Science is of a (...) different kind, not based upon some grand metaphysical view of any sort. Those who are active within this movement are emphatic in their insistence that instead of aiming at a synthesis of the different sciences on the basis of a prior and independent philosophy, the special sciences will themselves supply their own synthesizing glue. For appreciating the significance of this movement it is therefore necessary to keep in mind that its tendency is toward a unified science, departmentalized into special sciences, and not toward an artificial and speculative juxtaposition of an autonomous philosophy and an autonomous group of sciences.

The RSPO and RTRS are global private partnerships that have been set up by business and civil society actors from the North to curb de-forestation and to promote sustainable production of palm oil or soy in the South. This article is about the launch of new national standards in Indonesia and Brazil that are look-alikes of the global standards but have been set up and supported by government or business actors from the South. The two main questions of this article (...) are: do the new national standards in Indonesia and Brazil provide a fundamental challenge to the RSPO and RTRS, or do they demonstrate the successful diffusion and adoption of global private rules into national contexts? Do the new national standards help or undermine the RSPO and RTRS in their efforts to reduce de-forestation? Combining the theoretical notions of proto-institution and rival governance network, a comparative analysis is offered of the launch of the new national standards in Indonesia and Brazil. The conclusion is that, whilst the RSPO and RTRS have served as models for the general design and principles of the national standards, they really differ from the global standards in terms of normative contents: the national standards offer more room to palm oil plantations and large-scale soy producers to expand production at the expense of forests and other high conservation areas. Governments and producer associations in Indonesia and Brazil have not launched national standards to implement the RSPO or RTRS but to challenge these interventions from the North. (shrink)

2 Enoch 58–59 provides an esoteric and somewhat eccentric delineation of attitudes toward the mistreatment of animals within some sect of Egyptian Judaism, in all probability. Three attitudes, having to do with the mistreatment of animals in failing to feed them properly, the wrongful binding of animals for sacrifice, and possible secret sexual exploitation of animals, are delineated along with warnings regarding the effects of such treatment on the human soul at the great judgment. This linking of how humans treat (...) animals with how humans will be judged in “the great age” is unique in the literature of this period and demonstrates a deep concern for animal welfare that has been largely dormant in many facets of religion until more recent times.

We study the expressive power in the finite of the logic Fixed-Point+Counting, the extension of first-order logic which is obtained through adding both the fixed-point constructor and the ability to count. To this end an isomorphism preserving (`generic') model of computation is introduced whose PTime restriction exactly corresponds to this level of expressive power, while its PSpace restriction corresponds to While+Counting. From this model we obtain a normal form which shows a rather clear separation of the relational vs. the arithmetical (...) side of the algorithms involved. In parallel, we study the relations of Fixed-Point+Counting with the infinitary logics L r ∞ω (∃ ≥ m ) m∈ω and the corresponding pebble games. The main result, however, involves the concept of an arithmetical invariant. By this we mean a functor taking every finite relational structure to an expansion of (an initial segment of) the standard arithmetical structure. In particular its values are linearly ordered structures. We establish the existence of a family of arithmetical invariants (J r ) r≥ 1 with the following properties: $\bullet$ The invariants themselves can be evaluated in polynomial time. $\bullet$ A class of finite relational structures is definable in Fixed-Point+Counting if and only if membership can be decided in polynomial time on the basis of the values of one of the invariants. $\bullet$ The invariant J r classifies all finite relational structures exactly up to equivalence with respect to the logic L r ∞ω (∃ ≥ m ) m∈ω . We also give a characterization of Fixed-Point+Counting in terms of sequences of formulae in the L r ωω (∃ ≥ m ) m∈ω : It corresponds exactly to the polynomial time computable families (φ n ) n∈ω in these logics. Towards a positive assessment of the expressive power of Fixed-Point+Counting, it is shown that the natural extension of fixed-point logic by Lindström quantifiers, which capture all the PTime computable properties of cardinalities of definable predicates, is strictly weaker than what we get here. This implies in particular that every extension of fixed-point logic by means of monadic Lindstrom quantifiers, which stays within PTime, must be strictly contained in Fixed-Point+Counting. (shrink)

An “insightful” and in-depth look at anti-science politics and its deadly results (Maria Konnikova, New York Times–bestselling author of The Biggest Bluff). Thomas Jefferson said, “Wherever the people are well informed, they can be trusted with their own government.” But what happens when they aren’t? From climate change to vaccinations, transportation to technology, health care to defense, we are in the midst of an unprecedented expansion of scientific progress—and a simultaneous expansion of danger. At the very time we need them (...) most, scientists and the very idea of objective knowledge are being bombarded by a vast, well-funded war on science, and the results are deadly. Whether it’s driven by identity politics, ideology, or industry, the result is an unprecedented erosion of thought in Western democracies as voters, policymakers, and justices actively ignore scientific evidence, leaving major policy decisions to be based more on the demands of the most strident voices. This compelling book investigates the historical, social, philosophical, political, and emotional reasons why evidence-based politics are in decline and authoritarian politics are once again on the rise on both left and right—and provides some compelling solutions to bring us to our collective senses, before it's too late. “If you care about attacks on climate science and the rise of authoritarianism, if you care about biased media coverage and shake-your-head political tomfoolery, this book is for you.”—The Guardian.

Socially engaged art presents social situations to be understood, experienced, and evaluated as works of art while they simultaneously retain everyday non-art functionality. This article begins with an account of the definitional and evaluative concerns that socially engaged art engenders, outlining the debates around the relative importance of ethical and aesthetic values that result from this unsettled relationship between art and non-art. Based on this account, I argue that all socially engaged art requires successful performative bids that declare the work (...) to be art and that it is possible to identify the felicity conditions in which these bids are likely to be successful, as well as the perlocutionary effects that occur when a situation is categorized as art. I apply this analytic framework in a discussion and comparison of pieces by Santiago Sierra and Mierle Laderman Ukeles, demonstrating how this framework facilitates assessments that account for the works as art, while interrogating and evaluating the ethics of their categorization as art.

L'induction géneralisante et l'induction extrapolante : leur usage dans l'empirisme logique. La formation des théories et leur contrôle dépendent de la forme du langage. Dans l'empirisme scientifique, les prévisions, appropriées au contrôle, sont : 1° inductivement fondées et pratiquement contrôlables ; 2° ou bien inductivement fondées et pratiquement incontrôlables ; 3° ou bien non fondées inductivement et pratiquement contrôlables ; 4° ou bien non fondées inductivement et pratiquement incontrôlables. Nous ne disposons pas de règles générales d’induction ou de contrôle ; (...) l’évolution des sciences montre que nous ne pouvons être assurés d’avance de ce qui pourra nous soutenir ou nous ébranler dans l’acceptation ou le rejet des théories ou hypothèses.
