We describe a new class of experiments designed to probe the foundations of quantum mechanics. Using quantum controlling devices, we show how to attain a freedom in temporal ordering of the control and detection of various phenomena. We consider wave–particle duality in the context of quantum-controlled and the entanglement-assisted delayed-choice experiments. Then we discuss a quantum-controlled CHSH experiment and measurement of photon’s transversal position and momentum in a single set-up.
Kostos Axelos, Greek-born Professor of Philosophy at the Sorbonne and author of a trilogy in French, Le Déploiement de l'errance, and of several French translations of Lucás and Heidegger, attempts an important confrontation of the two thinkers whom many regard as the major thinkers in European thought today: Marx and Heidegger. To some this is a confrontation of the left and the right, but Axelos moves in an entirely different range altogether. Heidegger himself remarks that a confrontation with Marx must (...) be made in terms of the problem of history. Both Heidegger and Marx--to some extent as the heirs of Hegel--are philosophers of the future. Axelos' book is written from the Heideggerian standpoint, centering on Heidegger's interpretation of the present age in terms of Technik, which is itself a movement in the mission of Being. The movements of the Geschick, as Heidegger says in Der Satz vom Grund and as Axelos emphasizes, are a world-play. The task of a thinking concerned with the future is to play along with the play. The future in Marxist and Heideggerian terms is a "planetary" age, beyond all nationalism, ruled by a global or planetary technology. Thinking must decide whether and how such technology will be an instrument of liberation or of oppression. Axelos' confrontation raises many central and interesting questions: what is the relationship between Heidegger's Gelassenheit and Marx's praxis? What hope is there for a future governed by a play? etc. The book can be recommended as both original and provocative.--J. D. C. (shrink)
The goal of this essay is to illustrate how Ebrahim Moosa's method of “contrapuntal reading” can be applied fruitfully to the Sunni hadith literature. My case study is the set of penalties (hudud) for illicit sex, which include flogging, stoning, and banishment. I propose a fresh reading of these sacred texts that brings to the fore the ethical dimension of Prophet Muhammad's conduct, especially his strong reluctance to apply these measures. I conclude by identifying four ethical problems that the stoning (...) penalty raises and suggest how the hadith literature can be read to argue against the validity of this specific punishment.

An attempt to re-think, within and for the tradition of Husserl and Heidegger, certain central contributions of Greek thought. Interpretations of the Philebus and of other Platonic and Aristotelian texts concerned with problems arising therefrom are carried out; they culminate in an analysis of the fruitful union of intellectual power and impotence in philosophy. The existentialist framework often provides suggestions for the interpretation of difficult transitions in the classical works; conversely, the adherence to the arguments of the Greek texts strengthens (...) the existentialist position with respect to such concepts as world and rationality.--C.
