    Peirce’s Propositional Logic
    Review of Metaphysics 34 (3). 1981.
    BEFORE Frege’s Begriffsschrift, propositional logic was submerged in the often murky theory of the "hypothetical syllogism." With the exception of the Stoa, a handful of astute mediaeval logicians, Leibniz, and Bolzano, one might well obtain the impression from studying the history of logic that Frege created his theory ex nihilo—which is substantially true, since Frege was apparently little influenced by previous work. One might also obtain the impression, especially by reading Frege himself, t…Read more

    I do not think that previous writing on artifacts has been satisfactory, for reasons that will become clear. This situation has only been slightly remedied, I believe, by works such as my Artifacts, Agency, and Art Works, Dipert, sometimes referred to here as “AAA.” At the same time, I believe that a general notion of artifact is crucial for philosophy: the concept of an artifact is a central piece of our conception of the world. One of the important projects in the theory of artifacts that is i…Read more

    Artifacts, Art Works, and Agency
    Temple University Press. 1993.
    This is the first philosophical study of artifacts that is book length. In it Randall Dipert develops a theory of what artifacts are and applies it extensively to one of the most complex and intriguing kind of artifacts, art works. He presents his own account of what agents, intentions, and actions are, then uses these notions to clarify what it is for an agent to "make" something. From this starting point, he develops a full theory of artifacts and other artificial things - and, especially, a t…Read more

    Peirce, frege, the logic of relations, and church's theorem
    History and Philosophy of Logic 5 (1): 49-66. 1984.
    In this essay, I discuss some observations by Peirce which suggest he had some idea of the substantive metalogical differences between logics which permit both quantifiers and relations, and those which do not. Peirce thus seems to have had arguments?which even De Morgan and Frege lacked?that show the superior expressiveness of relational logics

    One of the most significant discoveries of early twentieth century mathematical logic was a workable definition of ‘ordered pair’ totally within set theory. Norbert Wiener, and independently Casimir Kuratowski, are usually credited with this discovery. A definition of ‘ordered pair’ held the key to the precise formulation of the notions of ‘relation’ and ‘function’ — both of which are probably indispensable for an understanding of the foundations of mathematics. The set-theoretic definition of ‘…Read more

    The Ethics of Cyberwarfare
    Journal of Military Ethics 9 (4): 384-410. 2010.
    The paper addresses several issues in the morality of cyberwar and cyberwarfare, defined as one nation's attacks on the governmental or civilian information systems of another nation. It sketches the diverse technical ways in which an attack may occur, including denial-of-service attacks and the insertion of various forms of malware. It argues that existing international law and widely discussed principles of Just War Theory do not straightforwardly apply to cyberwarfare, and many forms of cyber…Read more

    Preventive War and the Epistemological Dimension of the Morality of War
    Journal of Military Ethics 5 (1): 32-54. 2006.
    This essay makes three claims about preventive war, which is demarcated from preemptive war and is part of a broader class of ?anticipatory? wars. Anticipatory wars, but especially preventive war, are ?hard cases? for traditional Just War theory; other puzzles for this tradition include nuclear deterrence, humanitarian intervention, and provability a priori of the success of Tit-for-Tat. First, and despite strong assertions to the contrary, it is far from clear that preventive war is absolutely …Read more

    Philosophers have almost always said something about emotions and passions whenever they have discussed human mental life. Many have asserted that it is some emotions or, more broadly, passions, that are to be primarily valued and sought. These valued passionate states of mind might include emotions, moods, desires, belief-like feelings of conviction and commitment, and romantic or erotic love, which are typically scarcely distinguished. Not only are these states of mind lumped together, but the…Read more

    Few philosophers today know much about Charles Peirce’s metaphysics, although a great many know something about his epistemology, philosophy of science, and logic. Indeed, few Peirce experts have written much on his metaphysics or made it the focus of their research. To an extent, this is understandable. Peirce’s writings were left in a disastrously disorganized state (mostly unpublished), and the crucial papers on metaphysics from his later years have not yet been republished in the first-rate …Read more

    Thinking, Language, and Experience
    Review of Metaphysics 44 (3): 618-620. 1991.
    This is an extensive and diffuse collection of essays woven together by a number of leitmotifs. It is a work by a technically virtuosic professional philosopher for readers with the same credentials; even many of the complicated examples use extensive insider information about the institution of professional analytic philosophy in the last half of the twentieth century in the United States. In the sequence of its chapters, we see a development that in some ways mirrors Castañeda's philosophical …Read more

    The Puzzle of Music and Emotion in Rand's Aesthetics
    Journal of Ayn Rand Studies 2 (2). 2001.
    Randall R. Dipert argues that, at first glance, Rand's view of representational arts, such as literature and the visual arts, might seem to have little applicability to pure music. Nevertheless, Rand took music without words as a serious art form, and struggled to develop a plausible theory of music. As Torres and Kamhi note in What Art Is, Rand's approach probably contradicted certain elements of her full aesthetic theory. But her theory of music and its relationship to emotions offers some fas…Read more
