General Relativity (GR) serves as the foundational framework for modern gravitation, demonstrating exceptional consistency across local and intermediate cosmological scales. In this work, we propose a systematic, field-theoretic refinement of GR by incorporating effective viscoelastic responses into the spacetime fabric as higher-order constitutive corrections. Beginning from a modified…
Continual fine-tuning changes an LLM’s weights directly, unlike ordinary software upgrades. Drawing on the “Ship of Theseus” paradox, we ask when a fine-tuned model ceases to be usefully “the same” model with respect to its original alignment properties. We define Model Identity Continuity and a candidate index, the Theseus Stability Metric (TSM), combining a normalized, per-layer…

_Phicare (Philosophy and Care Repository)_. 2023Esta palestra, proferida no âmbito das comemorações do sétimo centenário da canonização de São Tomás de Aquino (1323-2023), aborda a temática do cuidado em fim de vida, com especial destaque para a contribuição do filósofo e teólogo português João Poinsot (João de São Tomás, 1589-1644). O texto situa-se na intersecção entre a reflexão filosófica, a…
_The Open Science Framework_. 2022The present document comprises the contents at a glance and the rationale for my doctoral research, currently being developed at IEF - Institute for Philosophical Studies of the Faculty of Arts and Humanities of the University of Coimbra under the direction of António Manuel Martins and Simone Guidi, as part of an IEF research scholarship supervised by Mário…
_Revista de Hispanismo Filosófico_ 25:328-330. 2020Este texto relata el Coloquio Internacional "Escuela Ibérica de la Paz: Derecho Natural y Dignidad Humana (Siglos XVI y XVII)", celebrado en la Facultad de Letras de la Universidad de Coimbra los días 24 y 25 de octubre de 2019. El evento, resultado de la colaboración entre el Centro de Filosofía de la Universidad de Lisboa (CFUL) y el Instituto…
_Studies in History and Philosophy of Science_. forthcomingIn the past few years, machine learning (ML) has been widely (and to an extent, successfully) implemented in medicine. However, uncertainties surrounding ML have made it difficult to establish the bases of its epistemic and methodological warrants. In the literature, a parallel has been drawn between medicine and ML, suggesting that we…
_Dedica Revista de Educação e Humanidades_ 19:453–463. 2021Este artículo presenta el Instituto de Estudios Filosóficos (IEF) de la Facultad de Letras de la Universidad de Coimbra, una Unidad de Investigación y Desarrollo (I+D) creada en 2016 y financiada por la Fundación para la Ciencia y la Tecnología (FCT) de Portugal. El texto traza la historia del IEF, que surge tras la disolución de su…
Reductive naturalism has been challenged by alleged performative contradictions concerning the theorist and the semantic or epistemic resources required for theorising. A particularly direct form arises when the theorist is pressed to affirm or deny her own existence: the report “I exist” appears to require a singular and irreducible subject that a wholly physical ontology may be unable to…
_Roczniki Filozoficzne_ 71 (4):5-23. 2023The reception of the heliocentric theory of Nicolaus Copernicus in Jewish thought of the 17th-century period is a good exemplification of the issue concerning the formation of the relationship between natural science and theology, or more broadly: between science and religion. The fundamental question concerning this relationship, which we can ask from…
_Studia Philosophiae Christianae_ 59 (2):205-218. 2023Profesor Krzysztof A. Meissner proponuje obraz transcendencji wynikającej z poznawania świata przez fizykę, która oznacza świat uniwersalnych i niezmiennych praw przyrody. Czy tego rodzaju wypowiedzi są uprawnione na gruncie fizyki, czy też należy uznać je za określony pogląd filozoficzny? Czy istnienie praw przyrody wskazuje na istnienie…
_Studia Philosophiae Christianae_ 61 (1):9-31. 2025W 2025 roku przypada 60. rocznica powstania czasopisma filozoficznego Studia Philosophiae Christianae (SPCh). Jest ono jednym z najdłużej istniejących czasopism filozoficznych w Polsce. Czasopismo powstało w 1965 roku z inicjatywy pracowników Wydziału Filozofii Chrześcijańskiej Akademii Teologii Katolickiej w Warszawie. Obecnie jest redagowane w…
_Philosophy and Technology_ 38 (2):1-26. 2025We argue for the epistemic and ethical advantages of pluralism in Reinforcement Learning from Human Feedback (RLHF) in the context of Large Language Models (LLMs). Drawing on social epistemology and pluralist philosophy of science, we suggest ways in which RHLF can be made more responsive to human needs and how we can address challenges along the way.…
_Studia Philosophica Estonica_ 19 (1):24-44. 2026According to the thesis sometimes known as “the guise of the good”, we can only want or desire something (or intentionally do something) if it appears good to us in some respect. Typically, when introducing this thesis, one finds contemporary authors using the Latin phrase sub specie boni. In medieval Latin formulations, however, the standard…
The more thorough analysis of the notion of miracle as an extraordinary event leads us towards distinguishing two more features of the miracle, i.e. its supernaturality and scientific inexplicability. Considering the miracle as the event caused by God’s action requires, in turn, distinguishing another element, which is the religious significance. Distinguishing and presenting the fundamental…

_Journal of Medical Ethics_ 52 (e1):16-21. 2026The increasing use of AI in healthcare has sparked debates about responsibility and accountability for AI-related errors. The difficulty in attributing moral responsibility for undesirable outcomes caused by increasingly autonomous (often opaque) AI systems has become a new focal point in the debate on ‘responsibility gaps’. We approach the problem of…
_Engineering Studies_ 15 (2). 2023The main aim of this paper is to evaluate the evolution of Accident Causation Models (ACMs) from the perspective of philosophy of science. I use insights from philosophy of science to provide an epistemological analysis of the ways in which engineering scientists judge the value of different types of ACMs and to offer normative reflection on these judgements. I…
