Two kinds of causal inference rules which are widely used by social scientists are investigated. Two conceptions of causation also widely used are explicated -- the INUS and probabilistic conceptions of causation. It is shown that the causal inference rules which link correlation, a kind of partial correlation, and a conception of causation are invalid. It is concluded a new methodology is required for causal inference.

Philosophers and scientists have maintained that causation, correlation, and "partial correlation" are essentially related. These views give rise to various rules of causal inference. This essay considers the "claims of several philosophers and social scientists for causal systems with dichotomous variables. In section 2 important commonalities and differences are explicated among four major conceptions of correlation. In section 3 it is argued that whether correlation can serve as a measure of A's causal influence on B depends upon the conception of (...) causation being used and upon certain background assumptions. In section 4 five major kinds of "partial correlation" are explicated, and some of the important relations are established among two conceptions of "partial correlation", the conception of "screening off", the conception of "partitioning", and the measures of causal influence which have been suggested by advocates of path analysis or structural equation methods. In section 5 it is argued that whether any of these five conceptions of "partial correlation" can serve as a measure of causal influence depends upon the conception of causation being used and upon certain background assumptions. The important conclusion is that each of the approaches (considered here) to causal inference for causal systems with dichotomous variables stands in need of important qualifications and revisions if they are to be justified.

During the past decades several philosophers of science and social scientists have been interested in the problems of causation. Recently attention has been given to probabilistic causation in dichotomous causal systems. The paper uses the basic features of probabilistic causation to argue that the causal modeling approaches developed by such researchers as Blalock (1964) and Duncan (1975) can provide, when an additional assumption is added, adequate qualitative measures of one variableś causal influence upon another. Finally, some of the difficulties and (...) issues involved in developing adequate quantitative measures are discussed, and it is concluded that the causal modeling measures cannot provide adequate quantitative measures.

In her paper entitled "Causal Laws and Effective Strategies" (1979), Cartwright sets out to establish the connection between laws of association and causal laws. In part Cartwright is trying to show the sense in which a cause increases the probability of its effect, and to explain what causal laws assert by giving an account of how causal laws are related to certain kinds of statistical laws. In section II we explicate the essential features of Cartwright's for- mulation and in section (...) III we argue that there are several reasons for believing that Cartwright's formulation is inadequate and must be rejected. Nonetheless, we believe Cartwright's formulation does contain two key insights into the nature of causation. In section IV we use these two insights to sketch out the key features of an alternative formulation that holds the certain laws of association are necessary conditions for causal laws. The alternative formu- lation, we believe, explains what it means to say a cause increases the probability of its effect. (shrink)

The purpose of this dissertation is to provide a defence of Aristotle's principle of contradiction against the critique made on it by Jan Lukasiewicz in an article he wrote in 1910 which was translated and published in the March 1971 number of The Review of Metaphysics. Lukasiewicz maintains in general that the law of contradiction has no logical worth. Specifically, he charges Aristotle with having several laws of contradiction instead of one as Aristotle claims; with attempting to prove the law (...) despite his claim that this is impossible and finally with failing in the very attempt to prove the law, or at least one of its formulations. In 20 chapters, each dealing with a respective section of Lukasiewicz's article, I attempt to show that all of Lukasiewicz's allegations are unfounded. My methodology is simply to follow Lukasiewicz through his 20 sections and compare what he says with what Aristotle actually wrote. If successful, this dissertation will show, in basic agreement with Professor Joseph Owens, that the best way to read Aristotle is on his own terms and not, as in the case of Lukasiewicz, via the latest developments in symbolic logic. I reiterate, with Aristotle, that the law of contradiction is the basic principle of being qua being and has logical worth precisely because of that fact. (shrink)

The essays in this book, by a variety of leading Augustine scholars, examine not only Augustine's multifaceted philosophy and its relation to his epoch-making theology, but also his practice as a philosopher, as well as his relation to other philosophers both before and after him. Thus the collection shows that Augustine's philosophy remains an influence and a provocation in a wide variety of settings today.

Now language is very important for philosophizing, and, as we shall see, especially important for metaphysics. Metaphysics is reflection on the world as intellectually experienced, and this means, on the world as known and formulated and expressed in language or discourse. As Frederick Woodbridge puts it, "Telling the truth about man's intellectual experience of the world, and trying to discover what that truth implies, is the business of philosophy." Naturally, this attempt leads beyond that intellectual experience of the world, (...) that formulation in discourse, to the world itself. It leads to the context in which the world is experienced reflectively, to the "immediately" or "directly" experienced world—to the world encountered in our many other ways of experiencing it than reflective, intellectual, or linguistic. For "intellectual experience" is a way of experiencing the world, and "linguistic formulation" is a way of expressing and articulating subject-matter encountered and experienced in many other ways.

In Sein und Zeit, Heidegger claims that (1) das Man is an 'existential' i.e. a necessary feature of Dasein's Being; and (2) Dasein need not always exist in the mode of the Man-self, but can also be eigentlich, which I translate as 'self-owningly'. These apparently contradictory statements have prompted a debate between Hubert Dreyfus, who recommends abandoning (2), and Frederick Olafson, who favors jettisoning (1). I offer an interpretation of the structure of Dasein's Being compatible with both (1) and (...) (2), thus resolving the Dreyfus-Olafson debate. Central to this resolution is the distinction between das Man and the Man-self. Das Man is one of three existential 'horizons', or fields of possibilities; the other two horizons are the world and death. At any time, Dasein encounters entities in one of two basic modes: either by 'expressly seizing' possibilities of the horizon, or by occluding these possibilities. These modes are 'existentiell', i.e. features of Dasein's Being that are possible, but not essential. Self-ownership and the Man-self are the two basic existentiell modes of being oneself, i.e. projecting everyday possibilities of oneself appropriated from the horizon of das Man. What differentiates these two modes is the stance one takes to the possibility of death, the existential horizon of being oneself. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:482 HISTORY OF PHILOSOPHY G. E. Michalson, Jr. TheHistoricalDimensions ofaRattonalFaith. Washington, D.C.: University Press of America, 1977. Pp. 222. $8.65. The primary intentionof this work is to argue that historical or ecclesiastical religion plays a vital role in Kant's religious thought, because it is necessary to provide a sensible content for the purely formal doctrine of Kant's "moral" religion. But Michalson resists that this strategy cannot succeed, because of (...) the technical requirements of Kant's eplstmology, and that we must ultimately encounter an "impasse" in Kant's thought on history and religion (pp. 77, 134, 169). This is an area of Kant's thought that has not until recently received the attention it deserves. A careful consideration of all the related issued helps one to recognize, from perhaps the most beneficial standpoint, how all the various parts of Kant's philosophical scheme fit together. Michalson quite rightly maintains that we must remain within the epistemological framework Kant has established for the Critical Philosophy. But unfortunately he recognizes only the negative aspects of this framework. What he chooses to call "Kant's principle of human limitations" (mentioned thirtynine times) is the essential element in his interpretation. Secondly, Michalson is unwilling to follow the lead of other commentators (e.g., Michel Despland and Ylrmiahu Yovel) in broadening the context still further in order to take into account the full scope of Kant's philosophical project. These two defects persist throughout Michalson's analysis, and ultimately they prevent any fruitful conclusions. The approach employed, in its most simple form, ~sto point out that historical religion belongs to the phenomenal order and that morality (as the basis for Kant's technical rehgious position) belongs to the noumenal order. Kant's recognition of the need to bridge this gap is dealt with in terms of the "schematism of analogy" (pp. 95, 112-13) mentioned in Religion withinthe Ltmits ofReasonAlone. Michalson provides an interpretation of the schematism m Chapter 3 and concludes that "Kant's Religion is not altogether consistent with certain basic teachings of the critical philosophy" (p. 132). His attempt to deal with this problem carries him into a discussion of teleology and the highest good (Chapter 4), and it is only in this concluding chapter that his various interpretive errors crystallze and produce their Inevitable consequences. Rather than emphasizing the negative aspects of Kant's conception of man, Despland offers Kant's positive perspective on man and his destiny----drawing, for example, on the Anthropologyfrom a PragmaticPoint of View. Employing equally good judgment, Yovel provides an interpretation of the highest good which shows it as the culmination (in the indefinite future) of the concrete process through which man's social, political, educational, and religious development takes place. These perspectives permit the historical dimension (both religious and secular) to be gradually transformed by the imposition of moral designs--as men ~lowly and painfully assume responsibility for directing the blind laws of nature into patterns that serve moral ends. Such commentators help us to see more clearly what Kant was attempting to achieve and how the elements of his total philosophical scheme are to be understood as interconnected. Michalson, on the other hand, has only his impasse to offer us. Because history is phenomenal and religion (as morality) is noumenal, he maintainsthat no bridge is possible between the two realms. But this is simply a failure to recognize Kant's strategy. For Kant is very careful to restrict knowledge (in the strict sense) to the phenomenal order. But he is equally clear in asserting that it is legitimate (indeed, necessary) to postulate those conditions which alone make it possible for us to act in conformity with the moral law. Therefore, we must postulate not only God and immortality but the possibility of a worldly order which conforms both to the laws of nature and to the moral law. And for Kant these postulates have the full strength of rational truths, m that--like the postulates of mathematics -reason cannot reject them. Interpreting Kant's phenomenon-noumenon distinction strictly (but misapplying it), Michalson insists that such a projected ideal state of the world is inconsistent with Kant's epistemological commitment. For such... (shrink)

A contribution to a set of case studies, titled “In the Humanities Classroom,” this essay describes a course on the deep history of Italy developed for a “semester abroad” program in Perugia during the spring of 2016. It describes, in particular, two class meetings in the middle of the term that focused on the use of DNA, archaeology, and anthropology to study the lives of seven women who are the ancestors of almost every European today, as “imagined” by the geneticist (...) Bryan Sykes in his book The Seven Daughters of Eve. These women lived between forty-five hundred and ten thousand years ago—from the period when glaciers expanded to cover much of the northern hemisphere until the “Neolithic revolution,” when, in the wake of the glaciers' retreat, people turned permanently to farming. The student-led discussions, reconstructed here, of the lives of these women show the value of addressing questions of deep history in an international setting, where the intersections and disjunctions of the global and the local are especially evident.

Il contributo sostiene che una versione lunga e composita del Viaggio notturno del profeta e della sua ascensione, attribuita a Ibn ‘Abbas attraverso una figura più tarda conosciuta come al-Bakri, è diventata molto popolare e largamente diffusa nel tredicesimo secolo. Qui si propone una traduzione del viaggio celeste di Muhammad a partire da un importante manoscritto inedito di Istanbul copiato nella penisola araba verso la fine del tredicesimo secolo. Questa traduzione si propone come strumento per gli studiosi interessati alla tradizione (...) islamica delle ascensioni celesti e per chi si occupa delle possibile influenze musulmane sull’opera di Dante. Nonostante non si dimostri che Dante avesse avuto accesso diretto a questa fonte nel momento in cui componeva la divina commedia, ci sono prove sufficienti che le versioni di questo racconto fossero diffuse in diverse parti del Mediterraneo, prima e durante la vita di Dante. L’autore fa propria la recente ipotesi interpretativa di Bencheikh che sottolinea il ruolo fondamentale della versione di Bakri del Mi’râj per la composizione dell’ormai noto Libro della Scala, tradotto in latino e lingua francese antico in al-Andalus nella seconda metà del tredicesimo secolo.This article argues that a long and composite version of the narrative of Muhammad's night journey and ascension, one often ascribed to Ibn 'Abbas via a later figure known as al-Bakri, became especially popular and widely distributed in the thirteenth-century CE. It offers a translation of the Tour of Paradise section from a particularly important unpublished Istanbul manuscript preserving this version, copied in the Arabian peninsula near the end of the thirteenth-century. This translation could serve as a resource to scholars who are interested in the history of Islamic ascension narratives, and interested in the question of possible Muslim influences on Dante's Divine Comedy. While the author of this article does not argue that Dante must have been aware of this particular manuscript as he composed his masterwork, he claims that there is enough evidence to suggest that versions of this narrative circulated in different parts of the Mediterranean before and during Dante's lifetime. He supports the earlier conjecture by Bencheikh that the Bakri versions were likely foundational to the composition of the now famous "Book of Muhammad's Ladder" that was translated into Latin and Old French in al-Andalus / Spain in the second half of the thirteenth-century.

The bacterial pathogen Listeria monocytogenes displays the remarkable ability to reorganize the actin cytoskeleton within host cells as a means for promoting cell‐to‐cell transfer of the pathogen, in a manner that evades humoral immunity. In a series of events commencing with the biosynthesis of the bacterial surface protein ActA, host cell actin and many actin‐associated protein self‐assemble to from rocket‐tail structures that continually grow at sites proximal to the bacterium and depolymerize distally. Widespread interest in the underlying molecular mechanism of (...) Listeria locomotion stems from the likelihood that the dynamic remodeling of the host cell actin cytoskeleton at the cell's leading edge involves mechanistically analogous interactions. Recent advances in our understanding of these fundamental cytoskeletal rearrangements have been achieved through a clearer recognition of the central role of oligo‐proline sequence repeats present in ActA, and these findings provide a basis for inferring the role of analogous host cell proteins in the force‐producing and position‐securing steps in pseudopod and lamellipod formation at the peripheral membrane.
