    Thomas Kuhn’s Theory of Rationality.Paulo Pirozelli - 2019 - Manuscrito 42 (3):1-46.
    According to a widespread view, Thomas Kuhn’s model of scientific development would relegate rationality to a second plane, openly flirting with irrationalist positions. The intent of this article is to clarify this aspect of his thinking and refute this common interpretation. I begin by analysing the nature of values in Kuhn’s model and how they are connected to rationality. For Kuhn, a theory is chosen rationally when: i) the evaluation is based on values characteristic of science; ii) a theory is (...)

    From Empirical Evidence to First Principles: Thomas Kuhn's Methodological Revolution.Paulo Pirozelli - 2021 - Veritas – Revista de Filosofia da Pucrs 65 (3):1-10.
    The Structure of Scientific Revolutions represented a milestone in the attempt to understand scientific development based on empirical observations. However, in the next decades after the publication of his book, history, psychology, and sociology became increasingly marginal in Kuhn’s discussions. In his last articles, Kuhn even suggested that philosophers should pay less attention to empirical data and focus more on “first principles.” The purpose of this article is, first, to describe this radical transformation in Kuhn’s methodological approach, from his initial (...)

    The Structure of Scientific Controversies: Thomas Kuhn’s Social Epistemology.Paulo Pirozelli - forthcoming - Filosofia Unisinos:1-17.
    Changes of theories are major events in science. Two main types of questions may be asked about them: i) how do scientists choose new theories?, and ii) how is consensus formed? Generally, philosophers do not distinguish these two questions. Kuhn, on the contrary, offers very different answers to each of these questions. Theory-choice, on the one hand, is explained through the application of epistemic criteria, such as accuracy and consistency; nonetheless, because these values do not prescribe a single choice, consensus (...)

    Thomas Kuhn’s Philosophy of Language.Paulo Pirozelli - 2020 - Trans/Form/Ação 43 (spe):345-372.
    Thomas Kuhn is mostly known for his contributions to the philosophy of science. However, it was chiefly to investigations in philosophy of language that he dedicated the last part of his career. The aim of this paper is to present a systematic view of Kuhn’s main ideas on this subject. I start by describing his theory of concept, in particular what he says about kind terms. Such terms, acquired in blocks that form contrast sets or “taxonomies,” are learned through ostensible (...)

  5. Sources of Understanding in Supervised Machine Learning Models.Paulo Pirozelli - 2022 - Philosophy and Technology 35 (2):1-19.
    In the last decades, supervised machine learning has seen the widespread growth of highly complex, non-interpretable models, of which deep neural networks are the most typical representative. Due to their complexity, these models have showed an outstanding performance in a series of tasks, as in image recognition and machine translation. Recently, though, there has been an important discussion over whether those non-interpretable models are able to provide any sort of understanding whatsoever. For some scholars, only interpretable models can provide understanding. (...)

    Individuals, Communities, and Groups in Thomas Kuhn’s Model of Scientific Development.Paulo Pirozelli - 2021 - Principia: An International Journal of Epistemology 25 (1).
    In The Structure of Scientific Revolutions, Thomas Kuhn resorts to concepts from several disciplines in order to describe the general patterns of scientific development. This blend of disciplines can be explained in part by Kuhn's intellectual path, from physics to history and then to philosophy of science; but it also points to a deeper methodological problem, which is the question of what is the real unity of analysis in his model of science. The primary intention of this article is, thus, (...)
