Patrick Heelan, with background in quantum theory and in hermeneutic phenomenology, investigated not only the hermeneutical philosophy of science but also the parallels between quantum mechanics and human experience in general and the logic of changes of worldview. Heelan’s closeness to Aristotle and Lonergan, often neglected, is discussed, and issues concerning Heelan’s treatment of the social context of science are raised.

Starting with some illustrative examples, I develop a systematic account of a specific type of experimentation--an experimentation which is not, as in the "standard view", driven by specific theories. It is typically practiced in periods in which no theory or--even more fundamentally--no conceptual framework is readily available. I call it exploratory experimentation and I explicate its systematic guidelines. From the historical examples I argue furthermore that exploratory experimentation may have an immense, but hitherto widely neglected, epistemic significance.

Open science hardware (OSH) are prototypes of laboratory instruments that use open source hardware to extend the purely epistemic (improving knowledge about nature) and normative (improving society) ideals of science and emphasize the importance of technology. They remind us of Zilsel’s 1942 thesis about the artisanal origins of science and instrument making that bridged disciplinary and social barriers in the 16th century. The emphasis on making, tinkering, and design transcends research, reproducibility, and corroboration in science and pushes to the forefront (...) educational, emancipatory, and aesthetic and exploratory uses. I will use two recent projects, OpenDrop electrowetting platform and Open Source Estrogen that make but also reflect OSH’s playful, expressive, and performative strategies and define the present practices as “artisanal science.” These hybrid and ambiguous practices bridge divides between present disciplines and skills but they also define science as an everyday activity directly connected to the private and public interests of the citizens. To describe this epistemic and normative ambiguity of artisanal science, I employ Hannah Arendt’s 1958 critique of homo laborans and homo faber and claim that science artisans (citizen scientists, geeks, makers, and hackers) offer an alternative to professionalization of science as practiced in the university and R&D laboratories. Science artisans design and build instruments to engage in civic “vita activa” over instruments but also leisurely “otium” outside of the work and science labor. OSH in this sense empowers individuals and communities to explore new connections between scientific practices, public actions, and private interests (leisure). The science artisans strive for and explore sovereignty, dignity, and freedom in an age immersed in science and technology controversies by bridging the divides between art, science, engineering, and humanities.

This paper discusses some philosophical aspects related to the recent publication of the experimental results of the 2017 black hole experiment, namely the first image of the supermassive black hole at the center of galaxy M87. In this paper I present a philosophical analysis of the 2017 Event Horizon Telescope (EHT) black hole experiment. I first present Hacking’s philosophy of experimentation. Hacking gives his taxonomy of elements of laboratory science and distinguishes a list of elements. I show that the EHT (...) experiment conforms to major elements from Hacking’s list. I then describe with the help of Galison’s Philosophy of the Shadow how the EHT Collaboration created the famous black hole image. Galison outlines three stages for the reconstruction of the black hole image: Socio-Epistemology, Mechanical Objectivity, after which there is an additional SocioEpistemology stage. I subsequently present my own interpretation of the reconstruction of the black hole image and I discuss model fitting to data. I suggest that the main method used by the EHT Collaboration to assure trust in the results of the EHT experiment is what philosophers call the Argument from Coincidence. I show that using this method for the above purpose is problematic. I present two versions of the Argument from Coincidence: Hacking’s Coincidence and Cartwright’s Reproducibility by which I analyse the EHT experiment. The same estimation of the mass of the black hole is reproduced in four different procedures. The EHT Collaboration concludes: the value we have converged upon is robust. I analyse the mass measurements of the black hole with the help of Cartwright’s notion of robustness. I show that the EHT Collaboration construe Coincidence/Reproducibility as Technological Agnosticism and I contrast this interpretation with van Fraassen’s scientific agnosticism. (shrink)
