The article reconstructs the main lines of three hypotheses in the current literature concerning the evolutionary pace which characterized the natural history of human language: the “continuist” and gradualist perspective, the “discontinuist” and evolution-free perspective, and the “punctuationist” view. This current debate appears to have a long history, which starts at least from Darwin’s time. The article highlights the similarities between the old and the modern debates in terms of history of ideas, and it shows the current limits of each (...) of these perspectives. In the final part, we present an alternative approach which considers human language not as a single trait, but as the result of a mosaic of different elements, some of which recently evolved, and some others gradually evolved and phylogenetically ancient. When matched with a tree thinking and comparative perspective, this view suggests that expressions of symbolic and linguistic behaviors in other human species could have preceded the more complex and systematic behaviors showed by Homo sapiens.

This well-written volume is an introduction, not to world history, but to the special genre of "Big History," as the subtitle indicates. Christian and his fellow big historians, reacting against popular scepticism toward "master narratives," seek to create a new class of grand works that incorporate not only the history of human society, but also of the Earth, its life, and the universe as a whole. Specialists in any of the fields covered by the volume may find rough spots in (...) the treatment of topics they know well, but given the scope of the effort I think it is fair to regard this as something like the first edition of a continuing work. Later editions would be strengthened—as would the Big History movement as a whole—by explicitly incorporating some discussion of teleological reasoning in science, and by deploying clear distinctions between processes that are teleomatic (such as star formation), teleonomic (such as organismal development), and classically teleological (such as intentional behaviour on the part of humans). In "Maps of Time," David Christian has given us a book full of interesting facts, and with ideas to argue for and against in every chapter. It should provoke lively discussion across a whole range of academic disciplines. (shrink)

French abstract: L’article étudie la relation de Peirce à Comte, en partant des critiques formulées dans ses écrits de jeunesse. Son enjeu est double : il relève d’abord d’une question d’histoire de la philosophie étonnamment peu traitée, alors même que Peirce lit, commente et critique Comte. Le second enjeu est épistémologique et métaphysique : Peirce voit dans la théorie comtienne des hypothèses une position proche du pragmatisme qu’il développe, mais grevée de présupposés nominalistes qui la rendent finalement intenable, à moins (...) que l’on n’en adopte une lecture « charitable ». La confrontation avec Comte semble alors être l’occasion privilégiée d’une explicitation de son propre pragmatisme. -/- English version (see link below on Cairn international) This article discusses Peirce’s relationship to Comte, based on criticisms made by Peirce in his early writings. It has a twofold purpose : firstly, addressing an important question in the history of philosophy that is surprisingly overlooked, even if Peirce reads, comments and criticizes Comte. The second issue is epistemological and metaphysical : Peirce sees in Comte’s theory of hypotheses a position close to the pragmatism he develops, but burdened with nominalist presuppositions that ultimately make it untenable, unless one adopts a “charitable” reading of it. The confrontation with Comte then seems to be a privileged opportunity, for Peirce, to clarify his own pragmatism. (shrink)

Darwin, Sex and Statusargues that a human sociobiology that mistakes evolutionary theory for theories of psychology and culture is wrong, as are psychologies that could never have evolved or social sciences that posit impossible psychologies. Status develops theories of human self-awareness, cognition, and cultural capacity that are compatible with evolutionary theory. Recurring themes include: the importance of sexual selection in human evolution; our species' preoccupation with self-esteem and relative standing; the individual as an active strategist, regularly revising culturally provided information; (...) and awareness as an impressionmanagement device. Culture is a somewhat structured information pool that itself evolves, often in ways that reduce the genetic fitness of its participants. (shrink)
