We describe an explicit construction of algebraic models for theories with non-standard elements either with classical or constructive logic. The corresponding truthvalue algebra in our construction is a complete algebra of subsets of some concrete decidable set. This way we get a quite finitistic notion of true which reflects a notion of the deducibility of a given theory. It enables us to useconstructive, proof-theoretical methods for theories with non-standard elements. It is especially useful in the case of theories with constructive (...) logic where algorithmic properties are essential. (shrink)

A collection of historical and contemporary writings that chronicle the development of the African critical response to attempts to ascribe a peculiar nature to the African character, and the debate in contemporary African philosophy on issues such as magic, witchcraft, aesthetics, and morality. Other topics include contemporary thought in French speaking Africa, and African traditional thought and Western science. Each selection is preceded by a synopsis. No index.

The narrow-the-scope proposal for defining racism posits that a narrow definition is preferable to a wide definition because the former better facilitates interracial dialogue. Important critiques of the narrow-the-scope proposal have so far focused on the content of narrow definitions. This paper argues that it is important to critique the use of narrow definitions, as well. An examination of white uses of the term “racism” reveals that narrow definitions tend to be interchangeable with individualist definitions, as individualism is an effective (...) framework for white co-optation in the service of white interests. Consequently, philosophers interested in theorizing racism for racial justice purposes ought to reject the narrow-the-scope proposal. Individualist forms of racism should be accommodated within a wide conception of racism that centers the phenomenon of white racism. (shrink)

For the materials of my discussion, I fall back upon Descartes. This philosopher demonstrates the existence of God in his Third Meditation. The ontological argument, however, is given not in the Third but in the Fifth Meditation. It is there expressed in a curious manner. It would seem, to go by literary expression, that he at this point unexpectedly thought of the argument, stumbled upon it, as it were. "Of the essence of material things, et derechef, de Dieu, qu'il existe"--and (...) again, of God, that He exists. The title is in itself provocative. We are told of the essence of material things. The consideration of quantity, of extension, leads to the recognition that size, shape, position and motion can be distinguished with respect to the body to which we attribute extension. Thus he is led to, or at any rate introduces, a doctrine of essence. There is an infinity of ideas that are forms, essences, or determinate natures, immutable and eternal. Most significantly of all, these determinate natures have not been invented by me, says Descartes, and do not in any way depend upon my mind. After one more paragraph there follows the ontological argument. (shrink)

Attempts a philosophical and critical investigation of Marx's analysis of value to suggest an ontological basis for a general theory of value.

: It is argued here that part of the attraction of African music in the Atlantic Diaspora is its roots in an oral tradition in which agency is often more important than words. This makes it possible for the music to have a moral significance, not merely with respect to the verbal content of the words of songs but also with respect to the manner in which it is composed and performed. As such, a performance may be liberating, even when (...) the words used in the performance are not. By reinforcing elements of the oral tradition in a culture based on notational literacy, the music of the Black Atlantic exemplifies an alternative to ideals embodied in a technological culture.

It has been established that the kinematics of the Voigt transformation, which lacks group structure, is different from that of the Lorentz transformation, and that the apparent kinematic asymmetry of the Voigt coordinate transformations may be understood as a conformally symmetric kinematics. Phenomena such as the kinetic energy of a moving body and the Doppler effect are not quite the same under the conformal Voigt transformation as they are for the usual theory developed with respect to the Lorentz group. Yet (...) the massenergy conservation law under the Voigt coordinate transformations and the mass-energy conservation law under the group of Lorentz transformations are identically the same. (shrink)
