Valor da ciência, defesa do conhecimento e Perspectival Realism: Entrevista com Michela Massimi

Michela Massimi é professora de Filosofia da Ciência no Departamento de Filosofia da Universidade de Edimburgo, onde também é afiliada ao Higgs Centre for Theoretical Physics. Membro de importantes sociedades filosóficas e científicas, como a Royal Society of Edinburgh, a Royal Astronomical Society, e a Académie Internationale de Philosophie des Sciences (membro correspondente) é presidente eleita da PSA, Philosophy of Science Association, para o biênio 2023-2024. Massimi, com dupla nacionalidade, italiana e britânica, estudou na Sapienza Università di Roma, na London School of Economics, e lecionou História e Filosofia da Ciência na University College London antes de mudar-se para Edimburgo. Massimi trabalha com Filosofia da Ciência em uma abordagem marcada pelo recurso à pesquisa histórica. Seus interesses amplos abarcam a Filosofia da Cosmologia, o realismo científico, os estudos de ciências, as relações entre ciência e sociedade, entre outros tópicos. Tem se destacado por defender o que chama de Perspectival Realism, se afastando tanto do realismo tradicional, quanto do pragmatismo e do relativismo. Nessa entrevista dialogamos com Massimi sobre temas como o valor da ciência, a defesa da ciência em épocas de negacionismo e obscurantismo e as características de sua posição filosófica.

The Metaphysics of Decoherence

The paper investigates the type of realism that best suits the framework of decoherence taken at face value without postulating a plurality of worlds, or additional hidden variables, or non-unitary dynamical mechanisms. It is argued that this reading of decoherence leads to a type of perspectival realism which is extremely radical, especially when cosmological decoherence is considered.

Eternalism and Perspectival Realism About the ‘Now’

Eternalism is the view that all times are equally real. The relativity of simultaneity in special relativity backs this up. There is no cosmically extended, self-existing ‘now.’ This leads to a tricky problem. What makes statements about the present true? I shall approach the problem along the lines of perspectival realism and argue that the choice of the perspective does. To corroborate this point, the Lorentz transformations of special relativity are compared to the structurally similar equations of the Doppler effect. The ‘now’ is perspectivally real in the same way as a particular electromagnetic spectrum frequency. I also argue that the ontology of time licensed by perspectival realism is more credible in this context than its current alternative, the fragmentalist interpretation of special relativity.

Leis, causas e poderes

This paper deals with the notions of scientific law, natural causes, and the powers of causes to produce their effects from the point of view of perspectival realism. In the first section I deal with the conception of cause defended by George H. Lewes, one of the forerunners of British emergentism, along with John Stuart Mill. In the next section I deal with the notion of heteropathic laws of Mill. In the last section I deploy these notions in my explanation of natural phenomena as emergent processes. I put emphasis on the fact that the base conditions of an emergent are not its causes.

A Double-Barreled Novel

This chapter explores Mark Twain’s Huckleberry Finn, the most celebrated novel of the late nineteenth century, as the most completely realized example of the perspectival realism of the Reconstruction generation. Addressing Twain’s relationship with Howells and considering the way Twain’s absorption of the categories of the “sentimental fool” and the practices of mugwump aestheticism fed into his approach as a novelist, this chapter reads Huckleberry Finn as an allegory of the irreducible complexity of emancipation. This reading overturns traditional readings of the novel that celebrate Huck’s raft as a space of utopian freedom. It also offers an alternative to the dilemmas encountered by readers who have confronted the novel’s minstrelized depiction of the escaped slave Jim. What Twain called his “double-barreled” novel must be read for the way the possibilities of emancipation are hidden in plain sight, obscured by symbols of freedom such as the raft. Written in an age of renewed federalism even as it looks back at the antebellum world, Huckleberry Finn invites the reader to consider the possibility that the multiplicity of jurisdictions and overlapping, nonunified character of the U.S. legal system might represent a route toward emancipation in a world in which, absent a uniform law, no community could represent true justice.

Referential and Perspectival Realism

Ronald Giere (2006) has argued that at its best science gives us knowledge only from different “perspectives,” but that this knowledge still counts as scientific realism. Others have noted that his “perspectival realism” is in tension with scientific realism as traditionally understood: How can different, even conflicting, perspectives give us what there is really? This essay outlines a program (some published, much forthcoming) that makes good on Giere’s idea with a fresh understanding of “realism” that eases this tension.
