This work addresses biological explanations and aims to provide a philosophical account which brings together logical-procedural and historical-processual aspects when considering molecular pathways. It is argued that, having molecular features as explananda, a particular non-classical logical language – Zsyntax – can be used to formally represent, in terms of logical theorems, types of molecular processes, and to grasp how we get from one molecular interaction to another, hence explaining why a given outcome occurs. Expressing types of molecular biology processes in (...) terms of the Zsyntax language allows us to represent causal interactions by taking into account their context-sensitivity, and amounts to partly reviving the spirit of the so-called received view of explanation – which aimed to capture scientific explanatory accounts in terms of their logical structure and their appealing to nomological relations. Such a partial revival is pursued by invoking here non-classical deductions and empirical generalisations, which are called to provide the epistemic norms to explain the behavior of molecular pathways.

My purpose in the researching and the writing of this thesis has been to investigate, and to try to explain, Frank Ankersmit's curious shift from his well expressed and firmly held narrativist position of "Narrative Logic", to an arguably contradictory, yet passionately held counter belief in the plausibility of a form of direct historical experience - an authentic unmediated relationship with the past. I am, accordingly, presenting here what I believe to be the most adequate explanatory account of/for Ankersmit's intellectual (...) journey. A journey which, in essence, constituted a substitution of his earlier representational, language centred philosophy of history for what might be taken as a new and mystical non-representational theory. This alternative theory of Ankersmit' s, lacking cognitive foundations, works on the basis of sensations, moods, feelings and therefore a consciousness deemed to be received directly from the past itself, and therein - for this thesis - lies its fatal weakness as a historical theory. Belief in the mystical may be all right at some level, if this is what is wanted, but a mystical experience itself cannot produce a historical re-presentation which is the only way that the past can be presented historically. Thus, I argue that Ankersmit's journey from language to experience - the latter phenomenon being more appropriately situated within the field of sociology/social theory and memory studies - is, in the end, a lost historical cause.

El objetivo del trabajo es mostrar que la revisión que los historiadores llevan a cabo en su disciplina se debe, en parte, porque se ha puesto en cuestión el presupuesto temporal sobre el que se construyó la historia como ciencia: el “pasado histórico”. En primer lugar, intento señalar de qué modo en Analytical Philosophy of History Danto expresa, en la estructura temporal de las oraciones narrativas, las características del “tiempo histórico” que subyace a la historiografía. La separación y distinción entre (...) pasado, presente y futuro; el tiempo como un flujo del futuro hacia el pasado; el privilegio epistémico del historiador por sobre el testigo constituyen algunos de los rasgos que, para Danto, distinguen a la historia de cualquier otro conocimiento. En segundo lugar, intentaré mostrar que estos presupuestos temporales se hacen visibles cuando, a partir de las catástrofes del siglo XX, la memoria es considerada como una forma privilegiada para acceder a ese pasado reciente. Es decir, el surgimiento de la memoria, a partir de los 80´s, pone en tela de juicio los presupuestos temporales que subyacen a la concepción del pasado histórico “a la Danto” y el rol que el testigo y el futuro tenían para el conocimiento histórico.

Product design is a process in which multiple understandings of technology and society are transformed into characteristics of a product, into skills found in the design team, and finally, into scripts that prefigure the use of the technology. Because of its particular concern with mutual transformations of objects, social collectives and subjects, activity theory seems a potentially powerful framework for analyzing the complexity of product design work. I utilize the concepts of motive and object of activity to analyze an innovation (...) process in a small high-tech company. This analysis shows that engagement with the novel objects in the design process led to a significant transformation in the expertise, organization of work and dominant motive of the work community. In theoretical terms, the analysis suggests an alternative to the idea that an activity has one objectified motive which is instantiated in an object in the material world. It may be sensible to analyze product design as poly-motivated and its motives as instantiated in a number of different project-objects. (shrink)
