The present paper develops arguments for the need to formulate the basic theories of physics in terms of a six-dimensional manifold, as opposed to the four-dimensional space-time continuum of conventional theory. Employing a purely classical approach, some of the dynamical consequences of such a formulation with regard to both electrodynamics and gravitation are evaluated. The results lead to interesting implications with regard to various questions such as the occurrence and importance of superluminal particles, the existence of two or more physically (...) distinct time scales, and the variation of the gravitational coupling constant G and the law of energy conservation. The analysis also suggests a physical interpretation of the additional coordinates that occur in the metric. (shrink)

A moving cultural biography of abolitionist martyr John Brown, by one of the most important African-American intellectuals of the twentieth century. In the history of slavery and its legacy, John Brown looms large as a hero whose deeds partly precipitated the Civil War. As Frederick Douglass wrote: "When John Brown stretched forth his arm... the clash of arms was at hand." DuBois's biography brings Brown stirringly to life and is a neglected classic.

William Ernest Johnson was a renowned British logician and economist, andalso a fellow of King's College, Cambridge. Originally published in 1924, this book forms the third of a three-volume series by Johnson relating to 'the whole field of logic as ordinarily understood'. The series is widely regarded as Johnson's greatest achievement, making a significant contribution to the tradition of philosophical logic. This book will be of value to anyone with an interest in Johnson's theories, philosophy and the historical development of (...) logic. (shrink)

Spanning pivotal years in the historic democratization of South Africa, this analysis provides a trenchant reflection of higher education in transition. Penned by one of South Africa’s foremost philosophers of education, the critique grapples with very real concerns in higher education policymaking and practice, including stakeholder politics, institutional cultures, and curriculum transformation and interrogation of the function of higher education institutions in modern societies. Exposing the tensions between egalitarian principles and the nature of higher knowledge, the essays raise questions to (...) which there are no simple answers. With characteristic rigor, the analysis looks into the assumptions underlying much of the thinking about these questions and concludes that a failure to sharpen thinking around higher education is a failure to recognize the epistemic value of academic practice in a developing democracy.

In this article I have tried to rebut certain types of arguments which purport to show not merely that God does not exist but that the notion of necessary existence is itself either self-contradictory or senseless. In showing that it is not self-contradictory I have allowed myself the luxury of a negative and a positive approach. Negatively, I have had to show that when the accusation of self-contradiction is made, it is often accompanied, not by an argument but by a (...) sheer assertion. On the rare occasions when an argument is forthcoming, the arguments, I have tried to show, have been invalid, not even, inconclusive. And to the extent that Kant may be said to have argued not simply the impossibility of a genuine proof of the existence of God, but indeed the impossibility of the concept of necessary existence, I have argued out the weakness of Kant's arguments, the most notable of which I have discussed in some detail. Finally, to establish the genuineness of the concept of necessary existence, positively, I have paradoxically made use of a notion from Russell's logic. (shrink)

I find this postulate of Mr. Blanshard's puzzling, and I wish to exhibit some perplexing features of it, and therefore of the business of the philosopher as he understands it.

Collection of essays aiming to give the reader a clear view of some important problems in esthetics, and to engage the mind in thinking them through.

Housed in one volume for the first time are several of the seminal essays on Du Bois's contributions to sociology and critical social theory: from DuBois as inventor of the sociology of race to Du Bois as the first sociologist of American religion; from Du Bois as a pioneer of urban and rural sociology to Du Bois as innovator of the sociology of gender and culture; and finally from Du Bois as groundbreaking sociologist of education and cultural criminologist to Du (...) Bois as critic of the disciplinary decadence of the discipline of sociology. Unlike any other anthology or critical reader on Du Bois, this new volume offers an excellent overview of the critical commentary on arguably one of the most imaginative and innovative, perceptive and prolific founders of the discipline of sociology.

Humans do two types of actions, polimorphic actions and mimeomorphic actions. The ability to carry out polimorphic actions cannot be mastered outside of socialization. Mimeomorphic actions, however, can be learned in other ways; sometimes, they can be learned away from the context of practice. Polimorphic actions cannot be mimicked by machines, but some mimeomorphic actions can. Other mimeomorphic actions are too complex to mechanize. Actions that cannot be mechanized because they are physically complicated should not be confused with actions that (...) cannot be mechanized because socialization is needed to master them. The analysis has implications for recent debates concerning the differences and similarities between humans and machines. The implica tion of the analysis is that much more can be understood about the relationship between humans and machines if the difference is treated as being a consequence of the unique properties of human societies. In this article, the analysis is applied to cardiac catheteriza tion, pacemaker implantation, simulation of bodies, and work in a medical "SkillsLab.". (shrink)

For--whatever our eventual sphere of control--the realm of fact is there first and always for our docility. Observ- ing is mental submission. Bacon is right: to master nature we must first obey her. Facts are to be received, learned, set in order: but who will say they are to be understood? They cannot be deduced: they are what they are. Here we meet the problem of these lectures. If man is to fathom his destiny, not to say guide it, must (...) his thinking not penetrate world fact as well as world law? And is this possible? (shrink)

'The problem of the twentieth-century is the problem of the color-line.' Originally published in 1903, The Souls of Black Folk is a classic study of race, culture, and education at the turn of the twentieth century. With its singular combination of essays, memoir, and fiction, this book vaulted W. E. B. Du Bois to the forefront of American political commentary and civil rights activism. The Souls of Black Folk is an impassioned, at times searing account of the situation of African (...) Americans in the United States. Du Bois makes a forceful case for the access of African Americans to higher education, memorably extols the achievements of black culture (above all the spirituals or 'sorrow songs'), and advances the provocative and influential argument that due to the inequalities and pressures of the 'race problem', African American identity is characterized by 'double consciousness'. This edition includes a valuable appendix of other writing by Du Bois, which sheds light on his attitudes and intentions. ABOUT THE SERIES: For over 100 years Oxford World's Classics has made available the widest range of literature from around the globe. Each affordable volume reflects Oxford's commitment to scholarship, providing the most accurate text plus a wealth of other valuable features, including expert introductions by leading authorities, helpful notes to clarify the text, up-to-date bibliographies for further study, and much more.
