Efforts to improve the means to diagnose and treat human genetic diseases have a long history in biomedical research and medicine. Now, preimplantation genetic diagnosis provides a new way to prevent the transmission of certain types of human genetic diseases to the next generation. It is an alternative to elective termination of pregnancies.PGD is used to test for genetic diseases that are due to defective single genes or abnormal chromosomes within days of fertilization and prior to the establishment of pregnancy. (...) The procedure essentially begins with the biopsy of one or more cells of a cleavage stage or blastocyst stage preimplantation human embryo that has been produced by in vitro fertilization. In certain cases, PGD can be done on polar bodies—discarded by-products of egg formation containing excess chromosomes—of unfertilized eggs. Then, the cell, or a polar body, is placed into a tube for single gene analysis ), or for chromosome analysis by spreading the nucleus of the cell on a microscope slide ). (shrink)

Recognized as America's most original philosopher, Charles Sanders Peirce (1839-1914) was a practicing scientist, a logician, and a student of medieval philosophy and the history of science.

I argue that the specter haunting multiculturalism is incommensurability. In many discussions of multiculturalism there is a ‘picture’ that holds us captive — a picture of cultures, religious or ethnic groups that are self-contained and are radically incommensurable with each other. I explore and critique this concept of incommensurability. I trace the idea of incommensurability back to the discussion by Thomas Kuhn — and especially to the ways in which his views were received. Drawing on Gadamer’s understanding of hermeneutics, I (...) argue that the very idea of radical incommensurability is incoherent. This does not entail an abstract universalism but rather sensitivity to the ways in which all languages and cultures are in principle open to the real possibility of enlarging one’s vision and mutually understanding.

"A fascinating and timely treatment of the objectivism versus relativism debates occurring in philosophy of science, literary theory, the social sciences, ...

Drawing freely and expertly from Continental and analytic traditions, Richard Bernstein examines a number of debates and controversies exemplified in the works of Gadamer, Habermas, Rorty, and Arendt. He argues that a "new conversation" is emerging about human rationality—a new understanding that emphasizes its practical character and has important ramifications both for thought and action.

Richard J. Bernstein is Vera List Professor of Philosophy at the New School for Social Research. The Essays: Philosophy, History, and Critique.

In her recent, provocative essay “What Is the Point of Equality?”, Elizabeth Anderson argues against a common ideal of egalitarian justice that she calls “ luck egalitarianism” and in favor of an approach she calls “democratic equality.”1 According to the luck egalitarian, the aim of justice as equality is to eliminate so far as is possible the impact on people’s lives of bad luck that falls on them through no fault or choice of their own. In the ideal luck egalitarian (...) society, there are no inequalities in people’s life prospects except those that arise through processes of voluntary choice or faulty conduct, for which the agents involved can reasonably be held responsible. Anderson asserts that the adherents of luck egalitarianism, which can be elaborated in many different ways, include John Roemer, Erik Rakowski, Thomas Nagel, Ronald Dworkin, Gerald Cohen, Richard Arneson, and Philippe Van Parijs.2 In contrast, according to the democratic equality conception, justice as equality requires an end to oppressive social relationships. In the ideal society of democratic equality, the social conditions of everyone’s freedom are secured, each stands to every other in a relationship of fundamental equality, including equal respect, and all have real freedom to participate in democratic self-government.

Leading philosophers and social thinkers, including Richard Rorty, Jacques Derrida, and Jurgen Habermas, pay tribute to the influential American philosopher Richard J. Bernstein.

Richard J. Bernstein argues that many of the important themes in philosophy during the past 150 years are variations and developments of ideas that were prominent in the classical American pragmatists: Charles S. Peirce, William James, John Dewey, and George H. Mead. The pragmatic thinkers reject a sharp dichotomy between subject and object, mind-body dualism, the quest for certainty, and the spectator theory of knowledge. They seek to bring about a sea change in philosophy that highlights the social character (...) of human experience and normative social practices, the self-correcting nature of all inquiry, and the continuity of theory and practice. And they - especially James, Dewey, and Mead - emphasize the democratic ethical-political consequences of a pragmatic orientation. Many of the themes developed by the pragmatic thinkers were central to the work of major twentieth-century philosophers such as Wittgenstein and Heidegger, but the so-called analytic/Continental split obscures this underlying continuity. Bernstein develops an alternative reading of contemporary philosophy that brings out the persistence and continuity of pragmatic themes. He explains why the discussion of pragmatism is alive, varied, and widespread"--Jacket. (shrink)

All of these essays focus on the concept of modernity in the philosophical work of Jurgen Habermas - an ambitious and carefully argued intellectual project that invites, indeed demands, rigorous scrutiny. Following an introductory overview of Habermas's work by Richard Bernstein, Albrecht Wellmer's essay places the philosopher within the tradition of Hegel, Marx, Weber, and Critical Theory. Martin Jay discusses Habermas's views on art and aesthetics, and Joel Whitebook examines his interpretations of Freud and psychoanalysis, Anthony Giddens offers a (...) critical reading of Habermas's major work, "The Theory of Communicative Action. Richard Rorty criticizes the whole thrust of his program by way of a comparison with the work of the French philosopher of postmodernity, Jean-Francois Lyotard. And Thomas McCarthy concentrates on the question of the selectivity of rationalization processes in the modern age. Habermas himself has three contributions - on Marcuse, on neoconservativism, and a reply to the other essayists. Richard J. Bernstein is T. Wistar Brown Professor of Philosophy at Haverford College. He was editor of the journal "Praxis International, in which these essays recently appeared. "Habermas and Modernity "is included in the series Studies in contemporary German Social Thought, edited by Thomas McCarthy. (shrink)
