We report a magnetization, magnetostriction, electrical resistivity, specific heat and neutron scattering study of a UNi 2/3 Rh 1/3 Al single crystal, a solid solution of an antiferromagnet UNiAl and a ferromagnet URhAl. The huge uniaxial magnetic anisotropy confining the principal magnetic response to the c axis in the parent compounds persists also for the solid solution. The magnetization curve at 1.6 K has a pronounced S shape with an inflection at 12 T. The temperature dependence of magnetic susceptibility exhibits (...) a maximum around 10 K and is magnetic history dependent at lower temperatures where the resistivity increases linearly with decreasing temperature. The low-temperature „ anomaly is removed in a magnetic field applied along c , which yields a large negative magnetoresistance amounting to m 46 z in 14 T . The C/T values exhibit a minimum around 12 K and below 8 K they become nearly constant , which is strongly affected by magnetic fields. Neutron scattering data confirm a non-magnetic ground state of UNi 2/3 Rh 1/3 Al. The bulk properties at low temperatures are tentatively attributed to the freezing of U magnetic moments with antiferromagnetic correlations. The additional intensities detected on top of nuclear reflections in neutron diffraction in a magnetic field applied along c are found to be proportional to the field-induced magnetization, which reflects field-induced ferromagnetic coupling of U magnetic moments. This scenario is corroborated also by finding low-temperature magnetostriction data that also scale with the square of magnetization. (shrink)

The paper proves that a historical method in Marxism is not identified to a dialectical method. The logic of history and the logic of its analysis in Marxism do not always coincide. The Logical coincides with the Historical only in eternity as it actually occurs in the works by G.V.F. Hegel. Eternity which has already witnessed everything does not know history any more. In the same way, history also begins there where the eternity comes to an end. Therefore, artificial identification (...) of the Logical with the Historical in Marxism led sometimes to actual mistakes. It is no wonder that it has always caused discussions in Marxism. They are mainly explained by the fact that the deductive, abstract-to-concrete method in which the “General” appears before the “Concrete” is an anti-historical method in its Nature. In real human history the “General” which is generalization of many “Concrete” could not appear before the latter in any way. For this reason, the real historical materialism needs an inductive method of knowledge. Only in that case historical materialism will cease to remain the soviet “histmat” and becomes the real form of a new world outlook. The author is of the opinion that the Party spirit of the Soviet philosophy promoted preservation of the anomalies mentioned in Marxism. The open discussion could help to find valid but not inherited from Hegel relation of historical and logical methods in Marxism. (shrink)

Les Enjeux du discours philosophique pour l'Afrique est consacré non pas à l'ethnophilosophie, mais à l'orientation africaine en philosophie ou de la philosophie qui se déploie sous des talents et plumes aussi riches que contradictoires : Placide Tempels, John Mbiti et Alexis Kagame, Nkrumah, Paulin Hountondji, Eboussi Boulaga, Marcien Towa, Niamkey Koffi, Abdou Touré, Yacouba Konaté, Jean-Godefroy Bidima, Augustin Dibi, etc. Ce n'est pas un ouvrage de "philosophie africaine", si l'adjonction de l'épithète africaine devrait trahir la philosophie qui, depuis (...) Platon, est universelle et ses "vérités" indépendantes des limitations géographiques, raciales et nationales. L'Afrique a, certes, ses limites dans tous les sens du substantif, mais la vocation trans-territoriale du discours philosophique demeure. Elle s'incarne dans le pari que prend Les enjeux du discours philosophique pour l'Afrique de redire, dans les termes de la théorie critique, de l'espace africain ce qu'il garderait sous un double voile d'ignorance et d'opulence. Il s'agit des défis rapportés aux langues, aux savoirs et aux orphelins du savoir, aux pouvoirs et aux orphelins du pouvoir, aux sous-développements et aux démocraties du même ordre, aux idéologies, etc. (shrink)

The scope and importance of the present work is manifest even to a casual glance; the actual heights of scholarly penetration and disinterestedness to which it rises can only be appreciated by the detailed examination of its text. From this latter examination, it readily appears that we are confronted with no ad hoc construction, no work cut, so to say, to fit a present need, however valid and cogent; but a work reflecting a near lifetime of application and animated by (...) a relentless devotion to documentary truth. For this reason, any account of it must, in simple justice, begin with a brief historical notice of the work itself. (shrink)

The issue of democracy is alive once more. There is a growing number of works debating the current state of democracy both in theory and practice.1 In particular a pragmatist conception of democracy has also been revived. Not only has a Deweyan version of a participatory democracy become the focus but the intricacies of a Rortian version have also come to the forefront, from both sympathetic as well as critical viewpoints.2 Thus the impression that the contemporary world is in quite (...) an exigent need of reconsidering—and perhaps even forming a novel conception of—democracy seems to be obvious, at least from a global point of view.3 Moreover, the fact that the idea or ideal of democracy still seems to be ..

В книге на материале психолингвистических экспериментов рассматриваются этические взгляды современных русских и японцев, причем этика русских прослеживается в динамике: на рубежах начала 1990-х гг. и начала XXI века.

In this short paper I propose that the sensorimotor approach to perception is a tree yielding two distinct theoretical fruits. One fruit is sensorimotor reductionism. The other is sensorimotor integrationism. In this paper I try to explain what makes these fruits different.
