The general question to be considered in this paper points to the nature of the world described by chemistry: what is macro-chemical ontology like? In particular, we want to identify the ontological categories that underlie chemical discourse and chemical practice. This is not an easy task, because modern Western metaphysics was strongly modeled by theoretical physics. For this reason, we attempt to answer our question by contrasting macro-chemical ontology with the mainstream ontology of physics and of traditional metaphysics. In particular, we introduce the distinction between stuff-ontology, proper of chemistry, and individual-ontology, proper of physics. These two ontologies differ from each other in the basic categories of their own structures. On this basis, we characterize individual-ontology in such a way that the features of stuff-ontology will arise by contrast with it

We show that a new interpretation of quantum mechanics, in which the notion of event is defined without reference to measurement or observers, allows to construct a quantum general ontology based on systems, states and events. Unlike the Copenhagen interpretation, it does not resort to elements of a classical ontology. The quantum ontology in turn allows us to recognize that a typical behavior of quantum systems exhibits strong emergence and ontological non-reducibility. Such phenomena are not exceptional but natural, and are rooted in the basic mathematical structure of quantum mechanics

In this paper, part of the ideas developed in Lewowicz (2000) will be reconsidered in the light of Pandora's Hope (1999a) - one of the latest publications of Bruno Latour. We will ponder the significance of these ideas and some of the incidental advances or retreats of the views of this author in the last 20 years. Although we still believe that, from the ontological point of view, Latour's philosophy is materialistic - then eliminativist - and not ontological relativist (contrary to the opinion of his colleague philosophers), some of the symmetries developed in that text show outstanding ontological-epistemological and even methodological deficiencies which we try to show here; especially the symmetry between 'human and nonhuman actors' (Latour 1999a) and his very singular (but not without a fair amount of antecedents) concept of history of the things whose neologism is that of pragmatogony. Andrew Pickering (The mangle of practice, 1999a) proposed and developed the concept of temporary emergency. In view of this concept, he succeeds in criticising Latour's exact symmetries making use primarily of the concept of intentionality to account for the asymmetry (by no means radical, according to the latter) between 'the human and nonhuman collective'. In this paper we will try to reinforce (and inevitably to question) the notion of temporal emergency by giving it a less local aspect than the one given by this author. We will not only hold the asymmetry of certain dichotomies - presumably avoided by and avoidable according to Latour - but we will also claim the historical impossibility of such an avoidance: the concept of historialised emergency and not just temporalised, precludes this. It is concluded, firstly, that only an eliminativist materialism (within the range of materialisms) is able to avoid and even 'overcome' such pairs like nature/society and some of its derivatives like subject/object and individual/collective. Secondly, the decisive character of some dichotomies will be defended and lastly it will be attempted to account for the almost only ontological possibility of constructivism: the eliminativist materialism.

En el presente trabajo se pone de relieve una tesis del último Kuhn que ha sido, y aún es, desatendida: el carácter no universal del lenguaje. Luego de ubicarla en los textos y contextos teóricos donde aparece, se intenta aclararla a partir de algunos de sus textos posteriores. En este afán, el trabajo presente en primer lugar muestra, cómo, deben ser modificadas algunas de las propuestas filosóficas atribuidas al Kuhn clásico para poder comprender esta tesis y en segundo lugar, intenta dar cuenta muy brevemente de ciertas innovaciones filosóficas del último Kuhn. Además, se comparan algunas de esas nuevas tesis de Kuhn con sus posibles -aunque nunca explicitados- interlocutores, a saber: N. Chomsky y J. Fodor. This paper draws attention to one of the theses of the Later Kuhn, which has been ignored: the non-universal character of language. After locating the thesis in the texts and theoretical contexts in which it appears, it is attempted to be clarified in view of some of his later texts. In regard of this, the paper firstly shows, how some of the philosophical proposals attributed to the Early Kuhn must be modified in order to understand it. Secondly, a very brief account for certain philosophical innovations in the Later Kuhn is attempted to be given. In addition, some of Kuhn's new theses are compared with his most likely, even if never explicit, interlocutors, namely N. Chomsky and J. Fodor

Finding out which terms – scientific or otherwise— fail to refer is an extremely complex business since both felicitous reference and failure to refer must be negotiated. Causal theories of reference –even so-called hybrid theories – posit that in order to refer to something, we need the regulative idea of an ontological reference, which operates even when we refer to impossibilia or inconceivable objects. Evidently, this is not the case of the referent of phlogiston, which is neither inconceivable nor impossible, nor, alas, does it exist. In the antipodes, from a representational-physicalist point of departure, a term fails to refer if it has no actual ontological grounds: phlogiston fails to refer because it has no physical existence. Phlogiston can even be considered to be a fictional entity, and referring to a fictional entity is not the same as a reference in a fiction or a fictional reference Salmon : a fictional entity is an object in the same sense as an abstract object, and therefore we can genuinely refer to it. The question is: who claims that phlogiston does not exist? Nowadays, everyone does, fundamentally and primarily because science has established it as a fact. The process that led to this result is extremely complex, lengthy and multi-dimensional. It involved factors of several kinds: cognitive, social, political, historical, as well as ontological, and this last factor has been neglected. I do not claim that phlogiston once existed and then ceased to exist -- science only allows us a sneak-peek into what exists and what, sometimes mistakenly, is supposed to exist. Paraphrasing Latour, this inquiry is about following the journey of the referents, even when they do not end up being physical-existent or existing objects. I believe with Bach that the notion of reference is essentially pragmatic; that the difference between alluding to something and referring to or denoting something must be established; that to achieve this the semantic properties of terms are not sufficient, and finally that references are not semantic but cognitive properties that relate thoughts and objects of any kind. My assumption is that to refer to something one must be capable of having thoughts about it and that the propositions one attempts to communicate in the course of referring to it are singular with respect to it. Being in a position to have a thought about a particular thing requires being connected to that thing, via perception, memory, communication and/ or education. Therefore, only in an exceedingly narrow realist theory of reference does phlogiston fail to refer. Unless a theory of reference of scientific terms is based on the study of the actual linguistic communicative practices among scientists, it will inevitably pose serious epistemological difficulties.

resumo: Este artigo pretende mostrar que sem a influência de uma filosofia construtivista que eu denomino boa, representada principalmente por Bruno Latour, a elucidação das substâncias químicas teria sido virtualmente impossível. Sem a noção de materiais “artefatuais” cunhada por eles, a Química Moderna seria impensável a partir dos metaparadigmas em uso no campo atual da história e da filosofia da ciência. A tese central que defendo aqui é a de que o construtivismo, tal como definido pelos antropológos da ciência, é uma maneira disfarçada de colocar a histórica filosofia materialista na trilha da discussão histórica e filosófica das ciências e tecnologias e que isso restaura o papel desempenhado pelos materiais usados pelos cientistas para que sejam exatamente o que são. abstract: This paper aims to show that without the influence of a constructivist philosophy I call good, mainly represented by Bruno Latour, the ontological elucidation of the chemical substances would have been virtually impossible. Without the notion of artifactual materials given by them, would be Modern Chemistry unthinkable from the metaparadigms in use in the present field of history and philosophy of science. The central thesis I defended here is that constructivism as defined by the anthropologists of science is a disguised way of sliding historical materialist philosophy into the mainline of philosophical and historical discussion of the sciences and technologies and that those restore the role played by the materials used by sciences to be exactly what they are

El riesgo que ha corrido Tecnos al publicar este libro no es menor y por ello vaya nuestra felicitación. Las recensiones de libros han sido concebidas como un género menor de la literatura filosófica. No obstante, ese género implica asuntos que no necesariamente se exigen en los “géneros mayores”: un compromiso con lo leído; un juicio de lo leído; y así un riesgo asumido. Además, si las recensiones están bien hechas, se puede conocer en pocas páginas, el compromiso general que los autores que recensionan tienen con su disciplina. La selección de los libros a reseñar, cuando es autónoma, implica la estética del autor que escoge, sus intereses y sus convicciones. Y entonces, nobleza obliga, sería bueno preguntarse si es lícito considerar las reseñas como un “género menor”.
