The human brain has some capabilities that the brains of other animals lack. It is to these distinctive capabilities that our species owes its dominant position. Other animals have stronger muscles or sharper claws, but we have cleverer brains. If machine brains one day come to surpass human brains in general intelligence, then this new superintelligence could become very powerful. As the fate of the gorillas now depends more on us humans than on the gorillas themselves, so the fate of (...) our species then would come to depend on the actions of the machine superintelligence. But we have one advantage: we get to make the first move. Will it be possible to construct a seed AI or otherwise to engineer initial conditions so as to make an intelligence explosion survivable? How could one achieve a controlled detonation? To get closer to an answer to this question, we must make our way through a fascinating landscape of topics and considerations. Read the book and learn about oracles, genies, singletons; about boxing methods, tripwires, and mind crime; about humanity's cosmic endowment and differential technological development; indirect normativity, instrumental convergence, whole brain emulation and technology couplings; Malthusian economics and dystopian evolution; artificial intelligence, and biological cognitive enhancement, and collective intelligence.

Francis Fukuyama's controversial new book, Our Posthuman Future: Consequences of the Biotechnology Revolution, has elicited varied reactions, but like it or not, it seems likely to be influential. Here are three opinions. —Ed.

Positions on the ethics of human enhancement technologies can be (crudely) characterized as ranging from transhumanism to bioconservatism. Transhumanists believe that human enhancement technologies should be made widely available, that individuals should have broad discretion over which of these technologies to apply to themselves, and that parents should normally have the right to choose enhancements for their children-to-be. Bioconservatives (whose ranks include such diverse writers as Leon Kass, Francis Fukuyama, George Annas, Wesley Smith, Jeremy Rifkin, and Bill McKibben) are generally (...) opposed to the use of technology to modify human nature. A central idea in bioconservativism is that human enhancement technologies will undermine our human dignity. To forestall a slide down the slippery slope towards an ultimately debased ‘posthuman’ state, bioconservatives often argue for broad bans on otherwise promising human enhancements. This paper distinguishes two common fears about the posthuman and argues for the importance of a concept of dignity that is inclusive enough to also apply to many possible posthuman beings. Recognizing the possibility of posthuman dignity undercuts an important objection against human enhancement and removes a distortive double standard from our field of moral vision. (shrink)

Though coming from different and distinct intellectual traditions, Richard Rorty and Gianni Vattimo are united in their criticism of the metaphysical tradition. The challenges they put forward extend beyond philosophy and entail a reconsideration of the foundations of belief in God and the religious life. They urge that the rejection of metaphysical truth does not necessitate the death of religion; instead it opens new ways of imagining what it is to be religious -- ways that emphasize charity, solidarity, and irony. (...) This unique collaboration, which includes a dialogue between the two philosophers, is notable not only for its fusion of pragmatism and hermeneutics but also for its recognition of the limits of both traditional religious belief and modern secularism. In "Anticlericalism and Atheism" Rorty discusses Vattimo's work _Belief_ and argues that the end of metaphysics paves the way for an anti-essentialist religion. Rorty's conception of religion, determined by private motives, is designed to produce the gospel's promise that henceforth God will not consider humanity as a servant but as a friend. In "The Age of Interpretation," Vattimo, who is both a devout Catholic and a frequent critic of the church, explores the surprising congruence between Christianity and hermeneutics in light of the dissolution of metaphysical truth. As in hermeneutics, interpretation is central to Christianity, which introduced the world to the principle of interiority, dissolving the experience of objective reality into "listening to and interpreting messages." The lively dialogue that concludes this volume, moderated and edited by Santiago Zabala, analyzes the future of religion together with the political, social, and historical aspects that characterize our contemporary postmodern, postmetaphysical, and post-Christian world.

This introduction to the philosophy of Jean-Luc Nancy gives an overview of his philosophical thought to date and situates it within the broader context of contemporary French and European thinking. The book examines Nancy’s philosophy in relation to five specific areas: his account of subjectivity; his understanding of space and spatiality; his thinking about the body and embodiment; his political thought; and his contribution to contemporary aesthetics. In each case it shows the way in which Nancy develops or moves beyond (...) some of the key concerns associated with phenomenology, post-structuralism, and what could broadly be termed the “post-modern.”.

Two of the most brilliant German thinkers of the twentieth century were Karl Jaspers and Rudolf Bultmann. Jaspers, the philosopher, and Bultmann, the theologian, were both influenced by the philosophy of Martin Heidegger and the rise of the existentialist movement. Late in their careers they interacted on the subject of Bultmann's attempt to divest Christianity of its mythical components and make sense of it in more modern terms. This work is a compilation of articles by Jaspers and Bultmann that formed (...) a running debate originally published in various scholarly journals. The first half of the book is Jaspers' lengthy and critical analysis of Bultmann's interpretation of Christianity, in which Jaspers essentially rejects the premise that Christianity or any other religion can or should be understood without its mythical framework. Jaspers charges that Bultmann has radically misunderstood the nature of myth and that myth is an irreplaceable form of symbolic communication. In the second part, Bultmann defends his approach, suggesting that Jaspers has not really understood his intent or meaning. Contemporary people today, schooled in the scientific tradition, are likely to reject the biblical texts because of their miraculous claims and supernatural content. Bultmann insists that the scholarly, scientific study of the Bible is a legitimate way to reveal its true message, apart from all the supernatural trappings. Finally, in response, Jaspers accepts some of Bultmann's clarifications but takes him to task on the subject of justification by faith, which he feels Bultmann defines too narrowly and too exclusively. This stimulating work by two penetrating minds will give anyone interested in perennial philosophical and theological questions much to ponder. (shrink)

The concept of the axial age, initially proposed by the philosopher Karl Jaspers to refer to a period in the first millennium BCE that saw the rise of major religious and philosophical figures and ideas throughout Eurasia, has gained an established position in a number of fields, including historical sociology, cultural sociology, and the sociology of religion. We explore whether the notion of an “axial age” has historical and intellectual cogency, or whether the authors who use the label of a (...) more free-floating “axiality” to connote varied “breakthroughs” in human experience may have a more compelling case. Throughout, we draw attention to ways in which uses of the axial age concept in contemporary social science vary in these and other respects. In the conclusion, we reflect on the value of the concept and its current uses and their utility in making sense of human experience. (shrink)

In 1919 Emily James Putnam gave twelve lectures at the New School under the title of “Habit and History.” The course description is as follows:The long predominance of habitual conduct over individual initiative in primitive society and in the early empires; the biological and social limitations which tend to foster habit and develop it beyond its proper sphere; the technique of habitbreaking inaugurated by the Greeks and becoming a characteristic of western society; an effort to appraise the amount of excessive (...) and undesirable habit in thought and action generally connected with such concepts as nationalism, religion, the status of women, etc.It is an interesting challenge, eighty-two years later, to try to understand what Mrs. James meant by that description and how to think about those issues today. Mrs. James contrasts the term `habitual conduct' to the term `individual initiative,' and finds the former more characteristic of primitive society and the early empires whereas the latter, beginning with the habit-breaking Greeks, is more characteristic of Western society. She does not reject habit altogether, indicating that it has a `proper sphere,' but only `excessive and undesirable habit,' and she suggests that nationalism, religion and the status of women are spheres where such excessive and undesirable habits are to be found.Without being able to peruse her lectures in detail, I cannot be sure of all that she is implying. One might note that in her contrast between habit and individual initiative she privileges, as until recently we have been wont to do, the West as against the rest. This contrast, with its whiff of Orientalism, might serve to warn us that, although the contrast at the heart of her lecture series is still part of our common sense today, it, like the contrast between the West and the non-West, ought not be affirmed until subjected to a degree of critical suspicion.
