The title of this book is not really catchpenny; it fairly indicates the contents. The theological disputation, held at Valladolid in 1550, about the lawfulness of the Spanish conquests in the New World, did largely turn upon the question whether the Indians were slaves in Aristotle’s sense or not. The entanglement of the institution of slavery with the natural law and the jus gentium is a very old one. It was not seriously undermined until the Stoics taught the universal citizenship (...) of the world and, far more effectively in the long run, Christianity taught the dignity of human nature. But the institution survived far into modern times—and perhaps still survives. Professor Hanke finds that some apologists of racial segregation in the United States and of apartheid in South Africa hold views scarcely distinguishable from Aristotle’s—that some men are naturally inferior and, in their own interests, should be ruled by the more capable.

Modal logics for reasoning about social networks is currently an active field of research. There is still a gap, however, between the state of the art in logical formalisations of concepts related to social networks and the much more mature field of social network analysis. In this paper we take a step to bridge that gap. One of the key foundations of social network analysis is balance theory, which is used to analyse signed social networks where agents can have positive (...) or negative relationships. Certain combinations of positive and negative relationships are considered to be unbalanced, or unstable—in particular the occurrence of cycles with an odd number of negative relationships. Especially relatively short cycles with an odd number of negative relationships are thought to put pressure on the agents to change one or more of the involved relationships from negative to positive or the other way around. Most existing logics for reasoning about social networks are defined for unsigned networks. In this paper we develop a modal logic for reasoning about structural properties of signed social networks, and give a sound and complete Hilbert-style axiomatic system. Furthermore, we completely axiomatise classes of signed social networks that are balanced to a certain degree n, in the sense that there are no cycles of length up to n with an odd number of negative relationships. Finally, we completely axiomatise the class of all fully balanced complete signed social networks, i.e., networks where everyone is connected with everyone else. Axiomatic completeness is non-trivial because neither the balance properties, nor the dichotomy between positive and negative relations, are modally definable. The paper thus provides a logical basis for reasoning about signed social networks in general and balanced networks in particular. (shrink)

Background Adherence to ethical guidelines and regulations and protecting and respecting the dignity and autonomy of participants by obtaining a valid informed consent form (ICF) prior to participation in research are crucial; The subjects did not add signatures next to the corrections made to signatures or dates on the ICF, Multiple signatures in other fields, ICF missing/missing signature, Incorrect ICF version Signed after modification, Correction tape used to correct signature, Impersonated signature, Non-research-member signature, however, ICFs are often not properly completed, (...) which must be addressed. This study analyzed ICF signing errors and implemented measures to reduce or prevent these errors. Methods We used the plan–do–check–act (PDCA) cycle to help improve the correctness and validity of ICF signing. Results Interim and final reports from January 2016 to February 2020 including 363 ICFs were studied. The total proportion of correct ICF signatures (200, 83.3%) following the PDCA intervention was significantly higher than that before the intervention (P < 0.05). Analysis of the types of signing error demonstrated that signature errors were significantly reduced after the intervention, particularly for subjects did not add signatures next to the corrections made to signatures or dates on the ICF (16, 6.7%) and impersonated signature (0; P < 0.05). Conclusions The proportions of other error types—multiple signatures in other fields, missing or unsigned ICF, incorrect signature order, incorrect ICF version, use of correction tape to correct signature, and non-medical profession members signing the ICF—did not differ significantly.

We introduce a framework for a graph-theoretic analysis of the semantic paradoxes. Similar frameworks have been recently developed for infinitary propositional languages by Cook and Rabern, Rabern, and Macauley. Our focus, however, will be on the language of first-order arithmetic augmented with a primitive truth predicate. Using Leitgeb’s notion of semantic dependence, we assign reference graphs (rfgs) to the sentences of this language and define a notion of paradoxicality in terms of acceptable decorations of rfgs with truth values. It is (...) shown that this notion of paradoxicality coincides with that of Kripke. In order to track down the structural components of an rfg that are responsible for paradoxicality, we show that any decoration can be obtained in a three-stage process: first, the rfg is unfolded into a tree, second, the tree is decorated with truth values (yielding a dependence tree in the sense of Yablo), and third, the decorated tree is re-collapsed onto the rfg. We show that paradoxicality enters the picture only at stage three. Due to this we can isolate two basic patterns necessary for paradoxicality. Moreover, we conjecture a solution to the characterization problem for dangerous rfgs that amounts to the claim that basically the Liar- and the Yablo graph are the only paradoxical rfgs. Furthermore, we develop signed rfgs that allow us to distinguish between ‘positive’ and ‘negative’ reference and obtain more fine-grained versions of our results for unsigned rfgs. (shrink)

Two principal sources of imprecision in legal drafting (vagueness and ambiguity) are identified and illustrated. Virtually all of the ambiguity imprecision encountered in legal discourse is ambiguity in the language used to express logical structure, and virtually all of the imprecision resulting is inadvertent. On the other hand, the imprecision encountered in legal writing that results from vagueness is frequently, if not most often, included there deliberately; the drafter has considered it and decided that the vague language best accomplishes the (...) purpose at hand. This paper focuses on the use of some defined terminology for minimizing inadvertent ambiguity in the logical structure of legal discourse, where desired by the drafter. The current set of signaled structural definitions that are included in the A-Hohfeld language are first set forth and their use is illustrated in an extensive example from the treaty establishing the European Economic Community. The use of definitions in legal writing is widespread, butaddressed almost exclusively to controlling the vagueness of substantive legal terms; they are seldom used for structural purposes. Furthermore, their use in American legislative drafting is unsignaled. Here, attention is devoted to the relatively-neglected domain in legal discourse of imprecisely expressed logical structure, and the remedy offered, where desired by the drafter, is a set of signaled structuraldefinitions for use in controlling such imprecision.

James Fitzjames Stephen is remembered as a judge, legal historian, and the author of Liberty, Equality, Fraternity, a reply to J. S. Mill's late works. He is less well remembered for his journalism, though it earned him a reputation among his contemporaries as one of the most trenchant writers on topics ranging across the social, religious, political, moral, and philosophical questions debated in his time. It was largely in his journalistic writing that Stephen set forth his views on these questions. (...) Despite such a reputation, however, only a small proportion of this writing was collected during his lifetime, and very little has been republished since his death.Selected Writings of James Fitzjames Stephen: On Society, Religion, and Government includes thirty-five essays expressing Stephen's views on the questions of his day, which have not lost their interest in ours. He wrote at a time when much of the finest writing in English was published in periodicals, often anonymously. The essays in this volume are drawn mostly from Stephen's unsigned contributions to the Saturday Review, with additions, both signed and unsigned, from other periodicals, extending from the 1850s to the 1880s.

The general view is that there is one type of nocturnal, which is universal, first illustrated in a printed book in 1524. Recently, a number of quite differently constructed nocturnals has come to light. Six of these were made at the very beginning of the sixteenth century by Falcono of Bergamo in northern Italy. One of them, with the initials of the inventor, may well be the prototype. Five more are closely similar. Five further nocturnals of the same type have (...) been identified, but they are unsigned, and are not by Falcono. This paper establishes the existence of a hitherto unrecognized Italian workshop, and of a variant type of nocturnal. (shrink)

Double-entry bookkeeping (DEB) implicitly uses a specific mathematical construction, the group of differences using pairs of unsigned numbers ("T-accounts"). That construction was only formulated abstractly in mathematics in the 19th century—even though DEB had been used in the business world for over five centuries. Yet the connection between DEB and the group of differences (here called the "Pacioli group") is still largely unknown both in mathematics and accounting. The precise mathematical treatment of DEB allows clarity on certain conceptual questions (...) and it immediately yields the generalization of the double-entry method to multi-dimensional vectors typically representing the different types of property involved in an enterprise or household.

This third volume in the definitive edition of Dewey's early work opens with his tribute to George Sylvester Morris, the former teacher who had brought Dewey to the University of Michigan. Morris's death in 1889 left vacant the Department of Philosophy chairmanship and led to Dewey's returning to fill that post after a year's stay at Minnesota. Appearing here, among all his writings from 1889 through 1892, are Dewey's earliest comprehensive statements on logic and his first book on ethics. Dewey's (...) marked copy of the galley-proof for his important article The Present Position of Logical Theory, recently discovered among the papers of the Open Court Publishing Company, is used as the basis for the text, making available for the first time his final changes and corrections. The textual studies that make The Early Works unique among American philosophical editions are reported in detail. One of these, A Note on Applied Psychology, documents the fact that Dewey did not co-author this book frequently attributed to him. Six brief unsigned articles written in 1891 for a University of Michigan student publication, the Inlander, have been identified as Dewey's and are also included in this volume. In both style and content, these articles reflect Dewey's conviction that philosophy should be used as a means of illuminating the contemporary scene; thus they add a new dimension to present knowledge of his early writing.

Since its rediscovery in 1903, the Logica Demonstrativa by Girolamo Saccheri is known in three editions ?1697, 1701, and 1735, the 1735, edition being posthumous. The 1697 edition is without the name of the author. This article calls attention to two unnoticed editions (1696? and 1699), the first one unsigned and the second by ?Carolus Iosephus Saccarellus?, a Saccheri pseudonym. The publishing history of the work has been partially clarified, though a number of problems remain unsolved. Après sa redécouverte (...) in 1903, on connait trois éditions de la Logica demonstrativa par Girolamo Saccheri (1697, 1701, 1735: cette dernière édition après sa mort). L'édition du 1697 est anonyme. L'article veut faire connaitre deux éditions inconnues (1696? et 1699), dont la première est ancore anonyme et la deuxième a comme auteur ?Carolus Saccarellus?, un pseudonyme de Saccheri. Ça éclaircit, en part, les questions liées à l'histoire des éditions de l'oeuvre. Hieronymi Saccherii Logica demonstrativa ex oblivione tracta est a Johannes Vailati, Italiae philosopho, Anno Domini 1903. Ter Logica edita fuit, in commune doctorum virorum opinione, annis Domini 1697, 1701, 1735. Quorum editionum, prima sine nomine auctoris est, postrema eius mortem secuta. Duas autem ignotas Logicae editiones inveni, alteram pariter sine auctoris nomine, alteram quodam Iosepho Saccarello ascriptam, certe ipsius Saccherii alienum nomen. Quae omnia nonnullas quaestiones de Logica demonstrativa illustrant. (shrink)

The J. A. Smith collection at Magdalen College, Oxford, contains an unsigned carbon copy, dated 1914, titled "The Theory of History." The manuscript, if Collingwood's, is his earliest essay on the philosophy of history. That "The Theory of History" may be Collingwood's is established by considerations of chronology, geography, and the appearance of certain intellectual interests mirrored in his other writing of the period 1913 to 1920. Present in the manuscript also are: the principles of the ideality of history, (...) or the unity of past and present in the historian's thought; the principle that historical knowledge presupposes judgment, and therefore, like knowledge generally, changes both knower and known; the conviction that the past is necessarily contemporary; the dialectic between judgment and evidence which is somehow not purely subjective but yields genuine knowledge, and the analogous rejection of the positivistic notions that history is unknowable; and the interest in and identification or near identification of philosophy and history. All these are seminal to everything Collingwood would write on history from 1913 to 1940. (shrink)

This paper examines the importance of artist names and artistic identity, especially as expressed in artist signatures, to the interpretation of ancient Greek pottery. Attention is focused on a calyx krater signed ΣϒPIΣKOΣ EΓPΦΣEN [sic], and it is argued that the non-Greek ethnikon used as artist name encourages a non-Athenian reading of the iconography. The painted labels for all six figures on this vase, together with parallels from other Athenian red-figure vases—including others from the Syriskos workshop—all suggest the presentation of (...) an alternative, un-Athenian world view. Okeanos, Dionysos, and Epaphos are read as representing faraway lands at the edges of the Ge Panteleia, or “entire earth,” while the central figure of Themis, Greek personification of divine right, is depicted pouring a libation to Balos, the Hellenized form of the Syrian supreme god Baal, thereby recognizing his status as a supreme deity. Other overtly political messages have been read elsewhere in the oeuvre of the Syriskos Workshop, where it seems that at least two distinct artistic identities were at play—the explicitly foreign “little Syrian,” and the more conventional Pistoxenos, or “trustworthy foreigner.” When explicitly signed on vessels, these artistic identities necessarily sway interpretation, whereas on the many unsigned pieces, the viewer is left to consider which identity is at play.

First published in 1848, Christian Discourses is a quartet of pieces written and arranged in contrasting styles. Parts One and Three, "The Cares of the Pagans" and "Thoughts That Wound from Behind--for Upbuilding," serve as a polemical overture to Kierkegaard's collision with the established order of Christendom. Yet Parts Two and Four, "Joyful Notes in the Strife of Suffering" and "Discourses at the Communion on Fridays," are reassuring affirmations of the joy and blessedness of Christian life in a world of (...) adversity and suffering. Written in ordinary language, the work combines simplicity and inwardness with reflection and presents crucial Christian concepts and presuppositions with unusual clarity. Kierkegaard continued in the pattern that he began with his first pseudonymous esthetic work, Either/Or, by pairing Christian Discourses with The Crisis, an unsigned esthetic essay on contemporary Danish actress Joanne Luise Heiberg.

In an 1894 manuscript addendum to the seminal "How to Make Our Ideas Clear", which he had written in 1877, Charles Peirce stated that "there are many people who detect the authorship of my unsigned screeds; and I doubt not that one of the marks of my style by which they do so is my inordinate reluctance to repeat a word". However, if Peirce refrained from repeating words in one and the same sentence, he surely did not refrain from (...) repeating words throughout all his writings, as this brief report will show.

In 1914, on the eve of the Great War, the eminent scholar and polymath, Theodore Merz, published what would be the final volume of his magisterial history of nineteenth-century European thought. A belated review of this volume appeared in the April 1918 issue of the American Historical Review. This particular review, though favorable, was inexplicably unsigned. Our paper offers compelling evidence that the author of this unsigned review was George H. Mead, the pragmatist philosopher from the University of (...) Chicago. The paper is organized in the following fashion. First, several types of documentary evidence are cited in support of the claim that Mead authored the unsigned review. Second, content analysis is used to identify themes in the review that reflect the distinctive intellectual concerns of Mead. One such concern was the ability of research-based science to address and rectify problematic aspects of social life. The concluding section of the paper reprints in its entirety Mead’s 1918 review.

In September 1981 the prestigious scientific journal Nature carried an unsigned editorial (subsequently acknowledged to be by the journal's senior editor, John Maddox) titled 'A book for burning?' (Maddox, 1981). It reviewed and damned Rupert Sheldrake's then recently published book A New Science of Life: The Hypothesis of Causative Formation (Sheldrake, 1981) and raised a storm of controversy whose fall-out is still very much with us. Up to this time Sheldrake was a well-respected up-and-coming plant physiologist and the recipient (...) of academic honours including a fellowship at his Cambridge college. The furore that grew out of the assault in Nature put an end to his academic career and made him persona non grata in the scientific community. Over twenty years later this journal still runs the risk of ostracism by publishing his work. What can explain this deep and lasting antagonism? (shrink)

This paper provides the framework for understanding Galileo’s request to the Grand Duke of Tuscany, in 1610, to be appointed in Florence as both Mathematician and Philosopher. By explicitly choosing such a title, he wished to stress the fact that his own work aimed at contributing to the new physical astronomy with which Copernicus inaugurated what is now called the Scientific Revolution. As opposed to Ptolemy, who understood astronomy as a purely mathematical tool in order to “save the phenomena” and (...) allow for accurate predictions, Galileo – very much in line with Copernicus and Kepler, as well as Newton after him – supported the reality of the Copernican system not only against Aristotle and Ptolemy, but also against Tycho Brahe. And, as it turned out after 1616, against the Church itself, which, in full accord with Osiander’s unsigned preface to the De revolutionibus, refused to see in the Copernican theory anything more than a mere working hypothesis to which astronomers were allowed to appeal only for computations.
