    The Abductive Structure of Scientific Creativity: An Essay on the Ecology of Cognition by Lorenzo Magnani
    Transactions of the Charles S. Peirce Society 56 (3): 456-465. 2021.
    Historians of philosophy will spill huge amounts of ink scrutinizing the reason why abduction was highlighted so much in the first two decades of the 21st century. Not to mention the numerous scholarly articles on abduction published in logic, cognitive science, artificial intelligence, semiotics, and philosophy of science, several monographs on abduction appeared during this period: Magnani, Walton, Gabbay and Woods, Aliseda, to name a few. It looks as if they were responding to Hintikka’s infl…Read more

    To date there seems to be no disciplined way of distinguishing between ad hoc hypotheses and legitimate auxiliary hypotheses. This is embarrassing not just for Popperian falsificationist scientific methodology, for the need for such a distinction seems an important part of scientific practice. Do scientists bother about ad hoc hypotheses at all? Did any towering figure in the history of science care about ad hoc hypotheses? Ironically, the answers to these questions seem to be “Yes” and “No” in …Read more

    Toward a Scotistic Modal Metaphysics
    The Paideia Archive: Twentieth World Congress of Philosophy 9 48-54. 1998.
    The problem I tackle in this article is: Do we have in Scotus a modal logic or a counterpart theory? We need to take a rather roundabout path to handle this problem. This is because, whether it be in Lewis's original formulation or in others' applications, the crucial concept of 'counterpart' has never been clearly explicated. In section two, I shall therefore examine the recent controversy concerning Leibniz's views on modalities which centers around the counterpart relation. By fully exploitin…Read more

    This book offers a historical explanation of important philosophical problems in logic and mathematics, which have been neglected by the official history of modern logic. It offers extensive information on Gottlob Frege’s logic, discussing which aspects of his logic can be considered truly innovative in its revolution against the Aristotelian logic. It presents the work of Hilbert and his associates and followers with the aim of understanding the revolutionary change in the axiomatic method. Mo…Read more

    A Possible Dilemma for Situation Semanticists
    Foundations of Science 22 (1): 161-182. 2017.
    This paper examines the concept of information in situation semantics. For this purpose the most fundamental principles of situation semantics are classified into three groups: principles of the more fundamental kind, principles related to regularity, and principles governing incremental information. Fodor’s well-known criticisms of situation semanticists’ concepts of information target the first group. Interestingly, situation semanticists have been anxious to articulate either the principles o…Read more

    What if Haecceity is not a Property?
    Foundations of Science 21 (3): 511-526. 2016.
    In some sense, both ontological and epistemological problems related to individuation have been the focal issues in the philosophy of mathematics ever since Frege. However, such an interest becomes manifest in the rise of structuralism as one of the most promising positions in recent philosophy of mathematics. The most recent controversy between Keränen and Shapiro seems to be the culmination of this phenomenon. Rather than taking sides, in this paper, I propose to critically examine some common…Read more

    Haecceitas and the Bare Particular
    Review of Metaphysics 44 (2). 1990.
    ACCORDING TO DUNS SCOTUS, what makes a material substance an individual is a positive entity which falls within the category of substance and contracts the specific nature to this or that. That entity, called haecceitas, together with the formal distinction, constitutes the core of Scotus' theory of individuation. But what is haecceitas? Haecceitas is not definable. Nor can we be acquainted with it. Then how could we understand it? Both negatively and positively, Scotus himself tried to give an …Read more

    Isn’t the Indispensability Argument Necessarily Analogical?
    Proceedings of the Xxii World Congress of Philosophy 41 13-18. 2008.
    Both the defenders and the challengers of the indispensability argument seem to ignore the obvious fact that it is meant to be an analogical inference. In this note, I shall draw attention to this fact so as to avoid unnecessary confusions in any future discussion of the indispensability argument. For this purpose, I shall criticize Maddy’s version of the indispensability argument. After having noted that Quinean holism does not have to be one of the necessary premises, I shall suggest alternati…Read more

    Michael Friedman’s project both historically and systematically testifies to the importance of the relativized a priori. The importance of implicit definitions clearly emerges from Schlick’s General Theory of Knowledge . The main aim of this paper is to show the relationship between both and the relativized a priori through a detailed discussion of Friedman’s work. Succeeding with this will amount to a contribution to recent scholarship showing the importance of Hilbert for Logical Empiricism

    Misrepresentation in Context
    Foundations of Science 19 (4): 363-374. 2014.
    We can witness the recent surge of interest in the interaction between cognitive science, philosophy of science, and aesthetics on the problem of representation. This naturally leads us to rethinking the achievements of Goodman’s monumental book Languages of Art. For, there is no doubt that no one else contributed more than Goodman to throw a light on the cognitive function of art. Ironically, it could be also Goodman who has been the stumbling block for a unified theory of representation. In th…Read more

    Abduction and Estimation in Animals
    Foundations of Science 17 (4): 321-337. 2012.
    One of the most pressing issues in understanding abduction is whether it is an instinct or an inference. For many commentators find it paradoxical that new ideas are products of an instinct and products of an inference at the same time. Fortunately, Lorenzo Magnani’s recent discussion of animal abduction sheds light on both instinctual and inferential character of Peircean abduction. But, exactly for what reasons are Peirce and Magnani so convinced that animal abduction can provide us with a nov…Read more

    Where have all the Californian tense-logicians gone?
    Synthese 193 (11): 3701-3712. 2016.
    Arthur N. Prior, in the Preface of Past, Present and Future, made clear his indebtedness to “the very lively tense-logicians of California for many discussions”. Strangely,with a notable exception of Copeland, there is no extensive discussion of these scholars in the literature on the history of tense logic. In this paper, I propose to study how Nino B. Cocchiarella, as one of the Californian tense-logicians, interacted with Prior in the late 1960s. By gathering clues from their correspondence a…Read more
