    Abduction of Generalizations
    Theoria : An International Journal for Theory, History and Fundations of Science 27 (3): 345-363. 2012.
    _Abduction of generalizations_ is the process in which explanatory hypotheses are formed for an observed, yet puzzling generalization such as ``pineapples taste sweet" or ``rainbows appear when the sun breaks through the rain". This phenomenon has received little attention in formal logic and philosophy of science. The current paper remedies this lacuna by first giving an overview of some general characteristics of this process, elaborating on its ubiquity in scientific and daily life reasoning.…Read more

    On Theoretical and Practical Doxastic Attitudes
    Logos and Episteme 5 (4): 425-443. 2014.
    In the literature on doxastic attitudes, the notion ‘belief’ is used in both a coarse-grained and a fine-grained manner. While the coarse-grained notion of ‘belief,’ as the doxastic attitude that expresses any form of assent to its content, is a useful technical concept, the fine-grained notion, which tries to capture the folk notion of ‘belief’ in contrast with other doxastic concepts such as ‘acceptance’ or ‘degrees of confidence,’ is utterly ambiguous. In order to dispel this ambiguity, I int…Read more

    To envision a new particle or change an existing law? Hypothesis formation and anomaly resolution for the curious case of the β decay spectrum
    Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 45 27-45. 2014.
    This paper addresses the question of how scientists determine which type of hypothesis is most suitable for tackling a particular problem by examining the historical case of the anomalous β spectrum in early nuclear physics, a puzzle that occasioned the most diverse hypotheses amongst physicists at the time. It is shown that such determinations are most often implicitly informed by scientists' individual perspectives on the structural relations between the various elements of the theory and the …Read more

    Modelling Abduction in Science by means of a Modal Adaptive Logic
    Foundations of Science 18 (4): 611-624. 2013.
    Scientists confronted with multiple explanatory hypotheses as a result of their abductive inferences, generally want to reason further on the different hypotheses one by one. This paper presents a modal adaptive logic MLA s that enables us to model abduction in such a way that the different explanatory hypotheses can be derived individually. This modelling is illustrated with a case study on the different hypotheses on the origin of the Moon
