Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

À propos de la folie et de l’amour dans Crime et Châtiment de Dostoïevski

Second Moment

Crime et Châtiment raconte l’histoire de Raskolnikov à l’été 1865 à Petersbourg, qui assassine une vieille usurière et sa sœur. Dès avant son geste Raskolnikov se met au travail quant aux questions de la culpabilité, du châtiment et de la rédemption. Le texte présente la folie humaine selon deux modalités, la névrose et la psychose, chacune avec ses deux temporalités, c’est-à-dire un premier moment de conscience d’une séparation d’avec la réalité, et un second moment de séparation effective. Raskolnikov se trouve du côté de la psychose, sur un continuel point de basculement entre les deux temps et les folies de Catherina Ivanovna et, peut-être, d’Arcady Svidrigaïlov, se trouvent du côté de la névrose, avec seul Arcady qui ne bascule pas. La seconde idée est celle de l’enjeu du crime : peut-on se trouver parmi ses frères humains de cet amour inconditionnel qui serait capable d’aimer le criminel le plus abject ? Le paradoxe est que Raskolnikov, qui ne peut supporter la transgression au point de délirer une race pure, met au défi ce monde à aimer le coupable du crime le plus vil. Nous terminerons en proposant que l’amour ne puisse être qu’inconditionnel, même s’il ne peut être illimité.

Diatom Complexes

Ancient lake sediments of Bibirevo section in the Yaroslavl and Kostroma Volga region are studied by means of graphical analysis of taxonomical structure of diatom complexes. This method allowed to record critical points (change of areas of stability) in the development of a Neopleistocene lake during the transition from stage to stage, as well as from phase to phase.

The Refusal of Politics

Laurent Dubreuil provocatively proposes an extremist rethinking of the limits of politics – toward a break from politics, the political and policies. Rather than yet another re-articulation, he calls for a refusal of politics, suggesting a form of apolitics that would make our lives more liveable. The first chapter situates the refusal of politics in relation to different contemporary theoretical attempts to renew politics, and makes the case for a greater rupture. The second moment takes up what is liveable in life by way of apolitical experience, in contrast to appropriations of the collective, including a discussion of the arts. Finally, Dubreuil draws up an incomplete inventory of means: forms of existence – often frail and fleeting – that make an exit toward atopia.
