Most authors writing about the ethics of cyberwarfare have assumed that just war theory— including the revisionist perspectives—is a more-or-less finished and agreed-upon moral theory, and that just war theory (JWT) applies in large part or even completely to cyberwarfare. This chapter argues that these assumptions are largely mistaken. Rather, the details of JWT’s foundations significantly impact the ways it might apply to cyberwarfare, far more than they do for the moral conditions governing traditional wars. In particular, any account of coordinated rational behavior by states, including many contractual theories, would have to deal extensively with some startling results in game theory, such as deterrent-based arguments for preemption and sometimes massively punitive actions. Precisely because cyberwarfare has potentially modest effects, and might be capable of carefully calibrated actions with more predictable effects than is the case for other military means, deterrence theories for cyberwarfare would be quite different.

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, that very little was being done on propositional logic in the 19th century. This claim would be false. As one might expect from a philosopher who is sometimes grouped with Frege and De Morgan as one of the greatest nineteenth century logicians, Charles S. Peirce dealt extensively with propositional logic, or as he would have called it, with the theory of the hypothetical syllogism.

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.

I survey in this article the practical uses of computers in philosophy: except for logic, computers have not yet noticeably improved the quality of philosophizing, research, or pedagogy. They have made work easier. My main interest, however, is in the “substantive” impact that computers may have on philosophical problems, especially in metaphysics. I argue that logic, the notion of decidability, and the theory of computation all predated and did not require modern digital computers. In the philosophy of mind, there has been a persistent conflation of computationalism and physicalism. The two theses can and should be separated. Finally, I suggest that we see glimpses of a new metaphysics based on information and information transformations that goes far beyond the well‐trodden mind‐brain debates.

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.

Almost all discussions of cyberwarfare, other cyber-attacks, and cyber-espionage have focused entirely on the Internet as the chief means of damage – the Internet as a ‘vector,’ using a term from the theory of infectious diseases. However there are a variety of means, some of which have already been used, that involve cyber-exploitation using vectors other than the Internet. Malware can be installed in the integrated circuits of computers and servers, but also in any devices attached to them – thumb drives, CDs, printers, scanners, and so on. One can also use various forms of electromagnetic radiation at a distance of meters or more to exfiltrate data or to infiltrate corrupt data. I call this large and diverse family of unwanted interference with the functioning of information processing systems other-than-Internet (OTI) attacks on information systems. Stuxnet, and probably the 2007 Israeli corruption of Syrian air defenses, were OTI attacks. Such OTI techniques are more difficult to develop than creating malware, requiring electronic manufacturing facilities or novel technologies, and are thus accessible only to larger corporations and technologically sophisticated countries. Particularly vulnerable would be countries (like the United States and Europe) whose information processing devices are mainly produced outside of the country. Once exploitations via the Internet become harder to perpetrate, OTI exploitations are certain to grow dramatically, eventually requiring equipment for critical uses to be expensively fabricated in (and transported using) secure facilities; expensive detection measures will have to be instituted. This will create challenges for policy, law, and ethics, as well as greatly increasing the cost of many electronic devices.

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 reasons why they are valued may likewise be various: they may be valued because of their intrinsic feeling (especially insofar as they are intense), through their long-term or deep effects on the rest of our practical and mental lives, through their effects on others’ lives, or even in the glimpse they give us of an object that transcends our mundane and superficial concerns, as in love, peak experiences, or intimations of God, Beauty, or Nature. Others have claimed that it is in the subduing or elimination of some or all of these passions that the ideal human life consists. Again, what precisely are the objectionable passions is typically not delineated, and why such mental states are objectionable may be diverse and even unspecified. One might resent their "disruptive" nature on our mental life, especially insofar as some of them stem from external, uncontrollable sources, and instead seek a calm state that is within one’s control and not subject to these whimsical externalities. Or one can see many or all passions as disruptive of control and success in our inner or outer life, or in the lives of others. We might call this latter group the anti-emotional Rationalists, and the former group the pro-emotional Romantics.

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 ‘ordered pair’ thus turned out to be a key victory for logicism, providing one admits set theory is logic. The definition also was instrumental in achieving the appearance of ontological economy — since it seemed only sets were needed — although this feature was emphasized only later.

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.
