Comment sommes-nous devenus humains? Quelle est la place de l'homme dans le vivant au XXIe siècle, vers quoi tend son devenir? Fort de son expérience de paléoanthropologue, mais aussi d'homme ancré dans son siècle et curieux de tout, le découvreur de Lucy interroge les grands enjeux de demain : l'écologie, la démographie, et bien sûr l'éthique. Etre humain et le rester est une aventure, une énigme, un défi qui nous concernent tous. Yves Coppens nous convie à un voyage dans (...) le temps et l'espace, à la découverte d'une matière en perpétuelle évolution : l'Homme. Chacun de ses invités, en livrant le récit de ses expériences et de ses recherches dans des domaines aussi variés que la philosophie, les sciences sociales ou la génétique, propose une vision singulière de l'humain en déroulant le fil lumineux de son devenir.

For many years, M. Jean d'Ormesson has been doing me the honor of asking me to write for Diogenes. More recently, he suggested that I should coordinate an issue of this review that would be devoted to my extended discipline, History, but history in the way in which I understand it. It was certainly not for lack of interest that I did not reply to the first request but, no doubt, because of the sense of a chronic lack of time (...) - almost a pleonasm - from which I, like everyone else, suffer. It was not because I was cured that I accepted the second invitation but probably because I allowed myself, with full knowledge of the facts, to entertain the idea that editing an issue would take up less time than simply contributing. … In fact, as everyone knows, the opposite is true, especially when the occasional editor also volunteers to be one of the contributors. This issue is now completed and I sincerely thank M. Jean d'Ormesson for having wished to entrust me with this task that I have enjoyed very much. (shrink)

In order to tell the story of Man and understand our emergence better, we can readily follow on from Heinz Tobien, though we do not need to go back so far in time - just a few million years.Clearly, our fundamental origin is animal. Thus it is easy to understand that in the great genealogy (known as phylogeny), there was one vital (geological) moment when our line was forever detached from the animal “kingdom.” The evidence of palaeontology, like that of (...) molecular biology, today locates this point - which is, by definition, the very point of origin of our family, the hominids - in Eastern Africa around 8 million years ago. In order to state this, palaeontology rests on two sets of results. All the most ancient hominids, without exception, are East African, and the oldest of all goes back more than 7 million years. Through the study of various characteristics of the cells of contemporary primates, having arranged them in an order of increasing complexity and having hypothesized that this contemporary complexity may be a reflection of that which developed through time, molecular biology has, on the basis of palaeontological dating, calibrated this transformation and its different stages and constructed what is called a molecular clock. In this way, it has arrived at two conclusions. The primates closest to Man are by far the great African apes (chimpanzees, gorillas), and the “distance” that separates us - in other words the degree of difference that exists between them and us - situates the divergence of our two branches at just over 7 million years.

This article inquires whether and to which degree some fundamental traits of the World Wide Web may encourage us to revise traditional conceptions of what constitutes scientific information and knowledge. Turning to arguments for `open access' in scientific publishing and its derivatives (open content, open archives, etc.), contemporary tendencies in `social software' and knowledge sharing, the authors project a new look on knowledge, dissociated with linear notions of cumulation, progression, and hierarchy (e.g. of scientific argument), but related to circularity, heterarchy, (...) and evolution. Arguing from a medium theoretical perspective, they illustrate their ideas with developments in library science, current debates in epistemology and theories about information architecture, with a particular focus on `unsystematic' folksonomies.

The conception of “prospective potency” was defined by its author H.Driesch as “the sum of the possible modes of development of a given part of the embryo”. However, in the language of science the word “potency” usually means “power”, not “possibility”. Therefore this conception from the beginning possessed a certain ambiguity, that it retained up to the present. The distinction of “active” and “passive” potency, introduced by Roux, has found no general acceptance. It appeared necessary to submit the conception of (...) “potency” to a profound analysis. In the first place it is shown, that the ambiguity of this conception vanishes, if we understand by the word “potency” those fundamental properties of the embryonic material, that are responsible for its various developmental possibilities. We can distinguish among these properties the “reactive powers”, by which the embryonic material reacts to inductive stimulations, and its own “developmental tendencies”. These faculties only differ by their strength; a “reactive power” may change into a “tendency”, when its intensity increases during development; conversely, a “tendency” may change into a mere “reactive power” by a decrease of its strength. The determination of the material results from the conflict of its tendencies. The inductive actions interfere by strengthening or weakening different tendencies, and by activating new tendencies by reinforcement of the “reactive powers” of the embryonic material. (shrink)

This book raises in a new way a central question of Christology: what is the divine motive for the incarnation? Throughout Christian history a majority of Western theologians have agreed that God's decision to become incarnate in the person of Jesus Christ was made necessary by "the Fall": if humans had not sinned, the incarnation would not have happened. This position is known as "infralapsarian." A minority of theologians however, including some major 19th- and 20th-century theological figures, championed a "supralapsarian" (...) Christology, arguing that God has always intended the incarnation, independent of "the Fall." Edwin Chr. van Driel offers the first scholarly monograph to map and analyze the full range of supralapsarian arguments. He gives a thick description of each argument and its theological consequences, and evaluates the theological gains and losses inherent in each approach. Van Driel shows that each of the three ways in which God is thought to relate to all that is not God -- in creation, in redemption, and in eschatological consummation -- can serve as the basis for a supralapsarian argument. He illustrates this thesis with detailed case studies of the Christologies of Schleiermacher, Dorner, and Barth. He concludes that the most fruitful supralapsarian strategy is rooted in the notion of eschatological consummation, taking interpersonal interaction with God to be the goal of the incarnation. He goes on to develop his own argument along these lines, concluding in an eschatological vision in which God is visually, audibly, and tangibly present in the midst of God's people. (shrink)
