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 fascinating suggestions that accord with—and in some respects go beyond—the best recent thinking in musical aesthetics

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 prohibited in traditional Just War Theory, and it is also dubious that it is in all cases ?clearly illegal?. Second, the morality of both preemptive and preventive wars is shown to turn on epistemological considerations: on what degree and kind of justification the primary metaphysical facts of threat can be reasonably believed. Third, an argument is made that whatever epistemic threshold is held to be necessary, some preventive wars will exceed it, and that this is more likely with advancing technologies of information acquisition. Finally, the common argument that allowing all nations to follow policies of preventive war would result in more wars than barring such policies is shown to be mistaken by simulations in game theory. Suggestions are made about the derivation of traditional Just War criteria from more basic moral principles, and about their subtle failures as jointly necessary conditions for the morality of war

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 Peirce’s writings were left in a disastrously disorganized state (mostly unpublished), and the crucial papers on metaphysics from his later years have not yet been republished in the first-rate chronological edition, the incomplete Writings of Charles S. Peirce: A Chronological Edition , edited at Indianapolis by my friends. And then there is Peirce’s writing: an awkward, abrasive, arrogant, eclectic style that demands technical knowledge in diverse fields, especially logic, mathematics, and the natural sciences. His worst personality traits manifested themselves in his highly technical metaphysics—with its idiosyncratic, anti-Cantorian conception of continua, a pecularly mathematical phenomenology, and elaborate views on Darwinian and non-Darwinian evolution, for example. Finally, there is what might appear to be the bizarreness of the theory itself, as we shall see. Peirce was a kind of philosophical swashbuckler, a bold, courageous speculator on philosophical questions beyond most of our temperaments even to ponder. Ours is not the philosophical age of Errol Flynn but the minimalist age of Harrison Ford, with no grand gestures or speeches, just a series of small, no-nonsense gestures: we typically like our philosophy short, neat, "science-like," and isolated from other philosophical issues

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 cyberwarfare differ from previous forms of warfare in neither injuring nor killing human beings, nor causing lasting physical damage ? but can nevertheless cause serious harm to a nation's vital interests. Another dissimilarity with traditional warfare is in the degree of knowledge of the identity of an attacker (the ?attribution problem?). The paper argues that cyberwarfare is not amenable to regulation by international pacts and that we can expect long periods of low-level, multilateral cyberwarfare, a Cyber Cold War, as a game-theoretic equilibrium is sought,. The paper laments the lack of a cyberwarfare policy, and concludes that it is only by applying game-theoretic principles that strategies can be discovered that are both moral and effective in suppressing overall harm to all parties in the long run

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 theory of art works and performances of art works as artifacts. He proposes a theory of nature and of the value of nature as what is essentially nonartificial. Two chapters are devoted to value considerations: merit in artifacts generally, and the evaluation of art works and performance art as artifacts or intentional gestures. Believing that a developed theory of action and philosophy of mind is necessary for a developed aesthetics and philosophy of art, Dipert relies on classical and contemporary research on agency, actions, and intentions, and on the intentionalist theory of mental objects of Brentano and Meinong. Dipert considers artifacts to be physical entities, but he also includes in the definition thoughts, utterances, and performances. This vast category encompasses everyday household objects and tools, streets and edifices, as well as communicative and artistic artifacts. Especially with regard to artistic artifacts, Dipert proposes a theory of expression and communication as actions and extensively discusses the problems of interpreting and recognizing actions, artifacts, and art works.
