    A Modest Refutation of Manifestationalism.Alessio Gava - 2019 - Universitas Philosophica 36 (73):259-287.
    In their recent “A modest defense of manifestationalism” (2015), Asay and Bordner defend this position from a quite famous criticism put forward by Rosen (1994), according to which while manifestationalism can be seen as more compatible with the letter of empiricism than other popular stances, such as constructive empiricism, it fails nonetheless to make sense of science. The two authors reckon that Rosen’s argument is actually flawed. In their view, manifestationalism could in fact represent a legitimate thesis about the nature (...)

  2. Consequências para o empirismo construtivo da adoção de um padrão internalista na caracterização do processo de observação.Alessio Gava - 2015 - In Fátima R. Évora Marcelo Carvalho Jr (ed.), Filosofia da Ciência e da Natureza. Coleção XVI Encontro ANPOF. São Paulo, Brazil: ANPOF. pp. 239-250.
    Discutindo acerca das centenas de detecções de planetas extrassolares, que supostamente aconteceram desde 1989 e que ele considera (incorretamente) como instâncias de observações, Peter Kosso disse, justamente, que segundo os parâmetros de Bas van Fraassen esses objetos celestes seriam observáveis. Ora, tais astros poderiam sem dúvida ser observados diretamente (sem a necessidade de instrumentos), nas condições apropriadas. Mas, acrescenta Kosso, “esse tipo de epistemologia externalista, que permite que a justificação se baseie em informação que não temos a disposição (nós não (...)

  3. Somewhere Over The... What?Alessio Gava - 2016 - Filosofia Unisinos 17 (3):315-319.
    In order to defend his controversial claim that observation is unaided perception, Bas van Fraassen, the originator of constructive empiricism, suggested that, for all we know, the images produced by a microscope could be in a situation analogous to that of the rainbows, which are ‘images of nothing’. He added that reflections in the water, rainbows, and the like are ‘public hallucinations’, but it is not clear whether this constitutes an ontological category apart or an empty set. In this paper (...)

    Van Fraassen, a inferência da melhor explicação e a Matrix realista.Alessio Gava - 2019 - Problemata 10 (1):267-283.
    In a recent work published in this journal, “Van Fraassen e a inferência da melhor explicação” (2016), Minikoski and Rodrigues da Silva identify four critical lines proposed by Bas van Fraassen against the form of abductive reasoning known as ‘inference to the best explanation’ (IBE). The first one, put forward by the Dutch philosopher in his seminal book The Scientific Image (1980), concerns the distinction between observable and unobservable entities. Minikoski and Rodrigues da Silva consider that the distinction is of (...)

    Astroparticle Physics, a Constructive Empiricist Account.Alessio Gava - 2019 - Science and Philosophy 7 (1):21-40.
    Astroparticle physics is an interdisciplinary field embracing astronomy, astrophysics and particle physics. In a recent paper on this topic, Brigitte Falkenburg defended that only scientific realism can make sense of it and that realist beliefs constitute an indispensable methodological principle of research in this discipline. The aim of this work is to show that there exists an anti-realist alternative to this account, along the lines of what Bas van Fraassen showed in his famous book The Scientific Image. Problems and results (...)

    In Praise of Sorensen’s ‘Blockage Theory’ on Shadows.Alessio Gava - 2018 - Filosofia Unisinos 19 (2):161-166.
    In his famous book "Seeing Dark Things: The Philosophy of Shadows" (2008), Roy Sorensen put forward a ‘blocking theory of shadows’, a causal view on these entities according to which a shadow is an absence of light caused by blockage. This approach allows him to solve a quite famous riddle on shadows, ‘the Yale puzzle’, that was devised by Robert Fogelin in the late 1960s and that Sorensen presents in the form mentioned by Bas van Fraassen (1989). István Aranyosi has (...)

    É possível ver imagens? (Ou do porquê van Fraassen deveria rever a sua abordagem em relação a elas).Alessio Gava - 2018 - Griot 18 (2):143-160.
    In his last book (2008), Bas van Fraassen, the originator of constructive empiricism, put forward a table containing a categorization of images. His aim, however, was to discuss the reality of what they represent and not addressing the issue of images per se. One of the consequences is that it remained an open question what ‘public hallucinations’ - reflections in the water, rainbows and the like - are. In this paper it will be defended that only images in the relevant (...)

    Zeno and the Impossibility of Analogy.Alessio Gava - 2014 - Archai: Revista de Estudos Sobre as Origens Do Pensamento Ocidental 12:25-30.
    The reductio ad absurdum has been elected by Zeno as the only method permitting to descry the true reality, invisible both to the senses and to the common way of thinking. Showing some continuity with the previous philosophers, not only in the search for a procedure in order to speculation to advance, but also on the same route departing from what is nearer, more acquainted and particular (visible) toward what is less acquainted, more distant and universal (invisible), to say it (...)

    Do Constructive Empiricists See Paramecia Too?Alessio Gava - 2014 - Prolegomena 13:291-302.
    According to Bas van Fraassen, a postulated entity which can only be detected by means of some instrument should not be considered observable. In this paper I argue that (1) this is not correct; (2) someone can be a constructive empiricist, adhering to van Fraassen’s famous anti-realist position, even admitting that many entities only detectable with a microscope are observable. The case of the paramecium, a very well-known single-celled organism, is particularly instructive in this respect. I maintain that we actually (...)

  12. Qual ontologia para o empirismo construtivo?Alessio Gava - 2014 - Princípios: Revista de Filosofia 21 (35):413-427.
    Is there an ontological question relative to van Fraassen’s Constructive Empiricism? It seems so, despite this philosophical position, a reference for contemporary Empiricism, presenting itself as an epistemological thesis. It is, furthermore, a very up-to-date matter, as the Dutch philosopher has recently changed his mind about the possibility for us to observe common optical phenomena as the rainbow. This reveals the necessity for a discussion about the concept of phenomena as used by van Fraassen, as Foss stated more than twenty (...)

    The emphasis on the role of observation, one of the hallmarks of Empiricism, is reaffirmed by the primacy of the distinction between observable and unobservable in Bas van Fraassen’s Constructive Empiricism. In this paper it will be showed that, despite being one the main topics of discussion in contemporary philosophy of science, particularly thanks to van Fraassen, the question of observation and observability is actually so old as philosophy itself and has to do with the willingness, that defines empiricism, to (...)

    O empirismo construtivo e o argumento de Musgrave: um problema ou um pseudoproblema?Alessio Gava - 2018 - Trans/Form/Ação 41 (4):177-204.
    In 1985, Alan Musgrave raised a serious objection against the possibility that a constructive empiricist could coherently draw the distinction between observables and unobservables. In his brief response in the same year, Bas van Fraassen claimed that Musgrave’s argument only works within the so-called ‘syntactic view’ of theories, while it loses its force in the context of the ‘semantic view’. But this response was not adequate, or so claimed F. A. Muller, who published two articles in order to extend the (...)

    On the Definition of Observation as Justified True Perception.Alessio Gava - 2015 - Scientiae Studia 13 (1):123-141.
    The primacy of the act of observation, one of the hallmarks of empiricism, found new life in the centrality of the distinction, made in Bas van Fraassen's constructive empiricism, between observable and unobservable. As Elliott Sober have pointed out, however, it is not clear what van Fraassen understands by observing an object. Worse, the Dutch philosopher does not seem to consider that a clarification of this point is necessary. This, of course, represents an important lacuna in a position generally considered (...)

    The act of observing is crucial for constructive empiricism, Bas van Fraassen's celebrated position on the aim of science. As Buekens and Muller noted in 2012, the Dutch philosopher should have characterized observation as an intentional act, because observation in science has a purpose. In the present article, which will also address the distinction between observing and observing that, introduced by Hanson and Dretske, it will be shown that considerations about the intentionality of the act of observing are, on the (...)

    Why van Fraassen Should Amend His Position on Instrument-Mediated Detections.Alessio Gava - 2016 - Analysis and Metaphysics 15:55–76.
    Constructive empiricism is a prominent anti-realist position whose aim is to make sense of science. As is well known, it also crucially depends on the distinction between what is observable and what scientific theories postulate but is unobservable to us. Accordingly, adopting an adequate notion of observability is in order, on pain of failing to achieve the goal of grasping science and its aim. Bas van Fraassen, the originator of constructive empiricism, identifies observation with unaided (at least in principle) human (...)

    The notion of epistemic community is crucial for the characterization of observability, a cornerstone for Bas van Fraassen’s constructive empiricism. As a matter of fact, observable is, to him, a short for observable-by-us. In this work, it will be shown that the alleged rigidity of the author of The Scientific Image, apparently not very keen to admitting changes in the epistemic community (constituted – according to him – by the human race), is actually an assumption of modesty and good judgment; (...)

    The problem of the justification of inductive inferences, also known as ‘Hume’s problem’, seems to have lost strength since the early 20th century, following several authors’ denial that induction is the method of science. Van Fraassen went beyond this denial and recently stated that induction does not exist. It is our aim to show that, in order to bring forward a coherent vision of science, in his reconstruction it is the observable (a crucial term for his Constructive Empiricism) that is (...)

    Observation and observability represent a crucial topic in the philosophy of science, as the huge production of papers and books on the subject attests. Philosophy of perception, on the other hand, is a field of study that took root effectively in the last decades. Even then, apparently, the main theories on observation have neglected the issue of determining which is the object of a successful perception. As a consequence, some theses that have recently been proposed are actually paradoxical, despite deriving (...)

  21. How to Save van Fraassen’s Own Antirealism: A Modest Proposal.Alessio Gava - 2020 - Perspectiva Filosófica 45 (1):1-21.
    Bas van Fraassen’s antirealist view of science and its aim, constructive empiricism, notoriously rests upon a distinction between observable and unobservable entities. In order to back his empiricist stance, the Dutch philosopher put forward his own characterization of observability. Nonetheless, he acknowledges that the point of constructive empiricism is not lost if the line is drawn in a somewhat different way from how he draws it. This means that other characterizations of observability can support this antirealist stance, provided they allow (...)

    Martin Kusch has recently defended Bas van Fraassen’s controversial view on microscopes, according to which these devices are not ‘windows on an invisible world’, but rather ‘image generators’. The two authors also claim that, since in a microscopic detection it is not possible to empirically investigate the geometrical relations between all the elements involved, one is entitled to maintain an agnostic stance about the reality of the entity allegedly represented by the produced image. In this paper I argue that, contrary (...)

    The concept of observability is of key importance for a consistent defense of Constructive Empiricism. This anti-realist position, originally presented in 1980 by Bas van Fraassen in his book The Scientific Image, crucially depends on the observable/unobservable dichotomy. Nevertheless, the question of what it means to observe has been faced in an unsatisfactory and inadequate manner by van Fraassen and this represents an important lacuna in his philosophical position. The aim of this work is to propose a characterization of the (...)
