During the mid-18th century, when electricity was coming into its own, natural philosophers began to entertain the possibility that electricity is the mysterious nerve force. Their attention was first drawn to several species of strongly electric fish, namely torpedoes, a type of African catfish, and a South American "eels." This was because their effects felt like those of discharging Leyden jars and could be transmitted along known conductors of electricity. Moreover, their actions could not be adequately explained by popular mechanical (...) theories. Many of the early documents supportive of the hypothesis of animal electricity were associated with the Dutch colonies in South America. This article presents and examines those documents, and shows how Dutch scientists on both sides of the Atlantic conducted experiments and communicated with each other in the 1750s and 1760s. It reveals the important roles played by inquisitive physicians and lovers of nature in South America, and by natural philosophers and collectors of exotic specimens in the Netherlands—learned men who began to make a credible case for animal electricity in some exciting places at a pivotal moment in time.

How shall we understand apparently teleological systems? What explains their persistence and their plasticity? Here I argue that all seemingly goal-directed systems—e.g., a food-seeking organism, human-made devices like thermostats and torpedoes, biological development, human goal seeking, and the evolutionary process itself—share a common organization. Specifically, they consist of an entity that moves within a larger containing structure, one that directs its behavior in a general way without precisely determining it. If so, then teleology lies within the domain of the theory (...) of compositional hierarchies. (shrink)

This book opens by providing the historical context of Plato’s engagement with education, including an overview of Plato’s life as student and educator. The author organizes his discussion of education in the Platonic Corpus around Plato’s images, both the familiar – the cave, the gadfly, the torpedo fish, and the midwife – and the less familiar – the intellectual aviary, the wax tablet, and the kindled fire. These educational images reveal that, for Plato, philosophizing is inextricably linked to learning; (...) that is, philosophy is fundamentally an educational endeavor. The book concludes by exploring Plato’s legacy in education, discussing the use of the “Socratic method” in schools and the Academy’s foundational place in the history of higher education. The characters in Plato’s dialogues often debate – sometimes with great passion – the purpose of education and the nature of learning. The claims about education in the Platonic corpus are so provocative, nuanced, insightful, and controversial that educational philosophers have reckoned with them for millennia. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Introduction to Dei Filius and Theology TodayAndrew MeszarosThe pandemic year of 2020 quickly torpedoed the modest intentions of formally reflecting on the contemporary significance of Dei Filius on its 150th anniversary. Nevertheless, the year's delay proved providential: in holding an online symposium, "Dei Filius and Theology Today," on April 22–24, 2021, the symposium was able to reach more participants than could have realistically travelled to Ireland, and was able (...) to end on April 24, the same day Pius IX promulgated the constitution 151 years ago.1In what follows, I lay out briefly the rationale for the commemoration and the publication of its proceedings.The "Spirit of Vatican I"Perhaps the most consistently disputed theological issue of the last fifty years has been the correct interpretation of the Second Vatican Council. The dispute is often but inaccurately pitched as a tension between the spirit and the letter of the Council. While such a distinction is valid (for one cannot hold that the Council's meaning is utterly exhausted by its texts, nor can one simply collapse the spirit into the text), and while debates over the interpretation of a council in its aftermath is not unique in the history [End Page 793] of the Church, and while it is not uncommon for historians to attribute something equivalent to a "spirit" or ethos to a given period in the history of the Church, it is noteworthy that few if any contemporary Catholic scholars (whether historians, philosophers, or theologians) seek to identify the "spirit of Vatican I," let alone do so in order to establish an ecclesiastical program or stake out a "direction" in which to move. Indeed, what would such a "spirit of Vatican I" look like?For some the spirit of Vatican I might best be encapsulated by the episcopal motto of Vatican II's killjoy, Cardinal Ottaviani: semper idem—"always the same." In that motto we find, allegedly, all the close-minded, ahistorical rigidity and complacency that Vatican II's spirit of openness, aggiornamento, and reform tried to overcome. Such a caricature of both Councils, however, seems to violate the hermeneutical principle taught by the bishops gathered at the extraordinary synod of 1985, for any aggiornamento or reform that moves outside established tradition is an aggiornamento or reform that separates the spirit from the letter of the Council.In the same way, it is not legitimate to separate the spirit and the letter of the [Second Vatican] Council. Moreover, the Council must be understood in continuity with the great tradition of the Church, and at the same time we must receive light from the Council's own doctrine for today's Church and the men of our time. The Church is one and the same throughout all the councils.2An erroneous understanding of a conciliar spirit as an ecclesiastical license for a theological free-for-all might cause one to question the language of "spirit" in relation to a council. But this statement by the bishops suggests that there is a legitimate (and illegitimate) way of attributing a "spirit" to a council. Rightly understood, the spirit of any council is an ethos or shared disposition, catalyzed by that council, according to which the Church seeks to move forward on her pilgrim journey through history—the temps de l'église—which will come to a halt only at the second coming of the Son. (One might say that history's councils are the smaller events that help guide the Church in her mission to communicate the fruits that stem from the ultimate event of salvation history: namely, the dual sending of the Son and the Spirit.) Their doctrinal teaching must be safeguarded (1 Tm 6:20) and their practical directives implemented. It is an ethos, stemming from [End Page 794] a particular historical event, that moves individuals and the Church as a whole to accomplish these tasks in accord with that event.3To the extent that a council addresses a variety of concerns, both temporal and eternal, the spirit of any council will involve contextually dependent and temporary stimuli (e.g., the Lateran Councils' spirit of reform in relation to clerical abuse), and more...

What do submarine attacks, ant trails, and dating have in common? Not much, except that they are all instances of pursuit and evasion problems and all submit to elegant mathematical treatments. The mathematics involved in such problems is varied and interesting in its own right, but the applications breathe life into the mathematics and invite wider engagement—as the intense interest of the military in such problems, especially during wartime, demonstrates. Consider the problem of a submarine commander about to fire on (...) an enemy warship. The enemy warship, of course, refuses to co operate, and the warship keeps up its course across the open sea. The submarine commander needs a strategy to ensure that the torpedoes arrive where the warship will be by the time the torpedoes arrive. How does the commander do this, without knowing the warship’s course? After all, there is no guarantee that the warship will travel in a straight line or at a constant speed. One way for the submarine commander to proceed is to keep the torpedo always aimed at the ship, instantaneously adjusting its direction to changes in the warship’s position. If this is done, the torpedo will (typically) trace out an arc and (typically) strike the ship from behind. This is called a pure pursuit strategy and is important in many military applications (such as Second World War air battles). (shrink)

The early examples of self-directing robots attracted the interest of both scientific and military communities. Biologists regarded these devices as material models of animal tropisms. Engineers envisaged the possibility of turning self-directing robots into new “intelligent” torpedoes during World War I. Starting from World War II, more extensive interactions developed between theoretical inquiry and applied military research on the subject of adaptive and intelligent machinery. Pioneers of Cybernetics were involved in the development of goal-seeking warfare devices. But collaboration occasionally turned (...) into open dissent. Founder of Cybernetics Norbert Wiener, in the aftermath of World War II, argued against military applications of learning machines, by drawing on epistemological appraisals of machine learning techniques. This connection between philosophy of science and techno-ethics is both strengthened and extended here. It is strengthened by an epistemological analysis of contemporary machine learning from examples; it is extended by a reflection on ceteris paribus conditions for models of adaptive behaviours.

The album Echo was produced in a depressed, drug-riddled phase when Tom Petty’s first marriage was ending and his physical condition so degraded that he took to using a cane. Petty filmed no videos, avoided playing the album’s songs on the follow-up tour and reported little memory of its making. The thoughtfulness and self-reflection that traumatic circumstances spur distinguish the album. So too does the tendency to look backwards in times of crisis, whether in hopes of finding solidity in the (...) past or just out of exhausted inability to cope with the present. -/- While melancholically creative, the album might be regarded as an echoing of past musical fragments. The sprightly mix of acoustic and electric guitars, the backing vocal harmonies and the stories of loss in songs such as “Won’t Last Long” and “This One’s for Me” harken to Petty’s albums from the late 80s to mid-90s. “Accused of Love” similarly contains echoes of Petty’s more upbeat work, but with depressing lyrical undertones. The production qualities and lyrics of “Rhino Skin” recollect “Asshole,” a Beck cover from Petty’s previous album. “I Don’t Wanna Fight”—a Heartbreakers performance composed and sung by Mike Campbell—returns to the hard driving rock of Damn the Torpedoes. The lyrics, straight-laced drums and layered drones of electric guitars of “Free Girl Now” go back further to “American Girl,” which itself was influenced by psychedelic music. At the same time, all of this typifies Petty’s oeuvre. Throughout his career, he made music steeped in past rock traditions. He was also a seminal figure in Southern rock, with its emphatically nostalgic character. -/- The crisis that Petty was experiencing echoes throughout the album in more specific ways, with many songs repeating the theme of being up or down, high or low. The theme of fighting or not wanting to has an especially strong echo, showing up in “Swingin’,” “Billy the Kid” and “I Don’t Wanna Fight.” These songs, in turn, exhibit nostalgia for past icons, with protagonists going down hard like Billy the Kid; or going down swinging like Sonny Liston; or again like Benny Goodman, Glenn Miller and Sammy Davis in a punny reference to the swing era. -/- The retrospective feel of the album is one of looking to the past for the sake of self-preservation in the present, along lines discussed by Nietzsche. While symptomatic of illness, Nietzsche maintains this movement “springs from the protective instinct of a degenerating life which tries by all means to sustain itself and to fight for existence.” This seeming denial of growth can, as Nietzsche continues, be “among the greatest conserving and yes-creating forces of life.” Petty clearly associated Echo with personal grief, refusing to listen to it for years. As with many other examples of art, however, the album was also a way of surviving and growing beyond a present trauma, and one more specifically that compelled him to overcome an important part of his past, namely, his wife of 20-plus years. One can speculate that clinging to fragments of the past—musical and otherwise—was a way of coping with a difficult present and a fading past. (shrink)

Multidisciplinary studies have led to the discovery and characterization of cysteine string proteins (csps) in both Drosophila and Torpedo. Phenotypic analysis of csp mutants in Drosophila demonstrates a crucial role for csp in synaptic transmission. Expression studies of Torpedo csp (Tcsp) in Xenopus oocytes suggests that the protein has some role in the function of presynaptic Ca2+ channels. However, biochemical purification of Tcsp indicates that is associated with synaptic vesicles rather than with the plasma membrane of presynaptic terminals (...) where Ca2+ channels reside. These results suggest a model in which csps serve as a link by which docked synaptic vesicles could modulate the activity of presynaptic Ca2+ channels. (shrink)

Gascoigne, Robert In October 1962, the world was at imminent risk of nuclear war. In response to the failed CIA backed 'Bay of Pigs' invasion, Soviet Premier Nikita Krushchev had authorized the stationing of nuclear missiles in Cuba, only ninety miles from the coast of Florida. In response, President John F. Kennedy had ordered a blockade of Cuba, which the Soviet Union regarded as an act of war. In fact, the world came much closer to a nuclear exchange than has (...) long been realized. On October 27th 1962 the Soviet submarine B59 was tracked by a group of United States warships, made up of eleven destroyers and an aircraft carrier, which were using non-lethal practice depth-charges in an attempt to bring the submarine to the surface. The submarine had lost radio contact with Moscow, which-as we will see-had very shortly beforehand ordered the freighters carrying nuclear missiles to return home. Under the intense pressure of the situation, the captain of the submarine-who thought that war may already have broken out-was determined not to allow Russia to be humiliated by the capture of his submarine, and was prepared to fire a nuclear torpedo at the surrounding American warships. Three officers had to give permission for a nuclear missile to be launched-the captain himself, the political officer, and Vasili Alexandrovich Arkhipov, who, although second-in-command of submarine B59, was commander of the flotilla of submarines to which it belonged. Arkhipov overruled his brother officers and refused to authorize the launch of the torpedo. The world owes a great debt of gratitude to this Soviet sailor who may have prevented a nuclear exchange between the Soviet Union and the United States. My father once told me how an American priest had recounted to him that, during the height of the Cuban missile crisis, the queues for confession at New York's St Patrick's cathedral stretched all the way down the nave and out onto Fifth Avenue. Given the penitential practices and beliefs of the time, and the actual state of events, there was indeed good reason for that! (shrink)

Human cholinesterase has recently been sequenced and cloned. It is a glycoprotein of 4 identical subunits, each subunit containing 9 carbohydrate chains and 3.5 disulfide bonds. Protein folding is likely to be very similar in human cholinesterase and Torpedo acetylcholinesterase. The cholinesterases have no significant sequence homology with the serine proteases and seem to belong to a separate serine esterase family.

The present book takes a third path. Although it includes commentary on the great historical philosophers and tries to show contemporary relevance, the book introduces students to philosophy topically. While there are references to Buddhism, the Vedas, Islam, and so on, the issues addressed are the bread-and-butter mainstream subjects in broadly analytic Western philosophy. Any student who successfully completes a course based on this book will have a solid grounding in wide variety of topics in different subdisciplines, as well as (...) the pros and cons of different theoretical ways to address those topics. A student who masters the content of this book is well-placed to move on as a philosophy major in the vast majority of philosophy departments. The problems of philosophy are deeply interconnected, and there is no natural or obvious starting point from which to begin. Indeed, plausible arguments might be given for starting with almost any of the central problems in the field. You might think that we should surely start with epistemology; until we understand what knowledge is and settle the matter of whether and how we can gain any knowledge at all, how can we possibly determine whether we can have knowledge of God, or our moral duties, or the nature of the mind? Clearly epistemology is the most fundamental philosophical project. Wait-how can we be sure that knowledge is valuable to have? Or that we ought to care about gaining truth and avoiding error? We'd better start with axiology and sort out duty, obligation, and responsibility first. Normativity and ethics must be foundational. Of course, how can we determine what our epistemic responsibilities are if we don't antecedently know whether we are free to believe one thing rather than another, or if we are truly at liberty to make choices? Let's begin with the issue of free will and figure that out first. If we're not free, that torpedoes a lot of other philosophical agendas. Yet if we don't know what kinds of beings we are, how can we ever determine whether we are free? Maybe personal identity should be the first stop on the road. And so on. (shrink)

A challenger of traditions and boundaries A pivotal figure in 20th-century philosophy, Nelson Goodman has made seminal contributions to metaphysics, epistemology, aesthetics, and the philosophy of language, with surprising connections that cut across traditional boundaries. In the early 1950s, Goodman, Quine, and White published a series of papers that threatened to torpedo fundamental assumptions of traditional philosophy. They advocated repudiating analyticity, necessity, and prior assumptions. Some philosophers, realizing the seismic effects repudiation would cause, argued that philosophy should retain the (...) familiar framework. Others considered the arguments compelling, but despaired of doing philosophy without the framework. Goodman disagreed with both factions. Rather than regretting the loss of structure, he capitalized on the opportunities that arise when the strictures of tradition are loosened. Available individually by volume 1.
