How Can Liberal Democracies Defend Themselves against Tyranny?

Tyranny in the modern era turned toward totalitarianism through the idea that human nature needed to be “perfected”; communism's enemy was a matter of class, Nazism's a matter of race. Democracy would seem by definition to resist such ideologies, but even the modern democratic state now possesses mechanisms that can be turned in tyrannical directions: regulatory powers, social welfare systems, and the new tools of artificial intelligence and “big data.” American democracy has been trending toward the “direct” form of democracy that the Founders recognized in ancient Athens and were determined to avoid, a degree of popular sovereignty capable of producing demands upon government that, in turn, could transform a people's government into a government's people. The best defense may be found in classic American literature's examination of national character and identity.     

Re-examining the Australian public's attitude to military casualties: post-heroic or defeat-phobic?

Australia, like most other developed democracies, is often alleged to suffer from ‘casualty phobia’. The perception that the Australian public will not tolerate casualties in foreign conflicts has shaped the decisions of both civilian and military policy makers. Measures taken to protect Australian forces from casualties may, for instance, also serve to increase the risk to civilians in the country to which they are deployed. The USA underwent a similar debate some years ago. Innovative public opinion research techniques—especially ‘survey experiments’ which allow researchers to establish causal relationships by consciously manipulating one variable while holding others constant—have established that the American public are not reflexively casualty-phobic and that the impact of casualties on public opinion can be outweighed by other factors, such as the public's confidence in the mission's overall success. In this article, the author replicates one of the key survey experiments from the US debate, suitably adapted to Australian conditions, with a nationally representative sample of Australian voters. The author finds that the same pattern holds in Australia as in the USA: casualties do lower public support for a given mission, but the mission's chances of success matter more.     

Iron isotope analysis of red and black pigments on pottery in Nasca,Peru

The Nasca culture of the south coast of Peru developed during the first millennium ad and is known internationally for its elaborately decorated polychrome pots. Despite decades of iconographic analysis, little is known about the more technological aspects of Nasca pigment production and application. We present results from a pilot study on iron isotopes as a potential line of inquiry into the differences between red and black pigments in Nasca pigments. As well, we conduct a small firing experiment to examine potential changes in isotope composition. Our analyses show three significant results. First, firing does not change the isotopic ratios of Fe in pigments. Second, red and black pigments show differences in their iron isotope composition, which relate to differences in the minerals used to make the different colors. Third, naturally available hematite samples show greater isotopic variation than pigment samples, suggesting that people selected a limited range of iron oxides to produce pigments.     

Albert Lautman et le souci brisé du mouvement

We locate Albert Lautman's work as a sort of agent of the break of symmetry in the framework of the traditional opposition of speculative philosophy and the physico-mathematical sciences. The stakes for philosophy are, with very rare exceptions, very poorly perceived. On this level, we return to the question of Lautman's supposed «Platonism» and we confront it with its fundamental reading of Martin Heidegger. The consequences of this insertion in the heideggerian furrow are fundamental for a just restitution of this thought and this philosophy into what they retain in current thought. On the other side, that of Lautmanian entries in the field of mathematical physics, we insist on the extreme prospective alacrity of his gaze, his philosophic power which comes to reinforce this strange sensibility toward what constituted the essential part of theoretical mathematics and physics in his time. In this sense, his position occupies actually one of the nodal points of the «surrationalistic» landscape.     

Africa's earliest bananas?

The recent discovery of banana phytoliths dating to the first millennium BC in Cameroon has ignited debate about the timing of the introduction of this important food crop to Africa. This paper presents new phytolith evidence obtained from one of three sediment cores from a swamp at Munsa, Uganda, that appears to indicate the presence of bananas (Musa) at this site during the fourth millennium BC. This discovery is evaluated in the light of existing knowledge of phytolith taphonomy, the history of Musa, ancient Indian Ocean trade and African prehistory.
