This book is a historical study of influential currents in the philosophy of language and linguistics of the first half of the twentieth century, explored from the perspective of the English scholar C. K. Ogden (1889–1957). Although no ‘Great Man’ in his own right, Ogden had a personal connection, reflected in his work, to several of the most significant figures of the age. The background to the ideas espoused in Ogden’s book The Meaning of Meaning, co-authored with I.A. Richards (1893–1979), is examined in detail, along with the application of these ideas in his international language project Basic English. A richly interlaced network of connections is revealed between early analytic philosophy, semiotics and linguistics, all inevitably shaped by the contemporary cultural and political environment. In particular, significant interaction is shown between Ogden’s ideas, the varying versions of ‘logical atomism’ of Bertrand Russell (1872–1970) and Ludwig Wittgensten (1889–1951), Victoria Lady Welby’s (1837–1912) ‘significs’, and the philosophy and political activism of Otto Neurath (1882–1945) and Rudolf Carnap (1891–1970) of the Vienna Circle. Amid these interactions emerges a previously little known mutual exchange between the academic philosophy and linguistics of the period and the practically oriented efforts of the international language movement.

Abstract Initial excess protactinium (231Pa) is a frequently suspected source of discordance in baddeleyite (ZrO2) geochronology, which limits accurate U/Pb dating, but such excesses have never been directly demonstrated. In this study, Pa incorporation in late Holocene baddeleyite from Somma-Vesuvius (Campanian Volcanic Province, central Italy) and Laacher See (East Eifel Volcanic Field, western Germany) was quantified by U-Th-Pa measurements using a large-geometry ion microprobe. Baddeleyite crystals isolated from subvolcanic syenites have average U concentrations of ~200 ppm and are largely stoichiometric with minor abundances of Nb, Hf, Ti, and Fe up to a few weight percent. Measured (231Pa)/(235U) activity ratios are significantly above the secular equilibrium value of unity and range from 3.4(8) to 14.9(2.6) in Vesuvius baddeleyite and from 3.6(9) to 8.9(1.4) in Laacher See baddeleyite (values within parentheses represent uncertainties in the last significant figures reported as 1σ throughout the text). Crystallization ages of 5.12(56) ka (Vesuvius; MSWD = 0.96, n = 12) and 15.6(2.0) ka (Laacher See; MSWD = 0.91, n = 10) were obtained from (230Th)/(238U) disequilibria for the same crystals, which are close to the respective eruption ages. Applying a corresponding age correction indicates average initial (231Pa)/(235U)0 of 8.8(1.0) (Vesuvius) and 7.9(5) (Laacher See). For reasonable melt activities, model baddeleyite-melt distribution coefficients of DPa/DU = 5.8(2) and 4.1(2) are obtained for Vesuvius and Laacher See, respectively. Speciation-dependent (Pa4+ vs. Pa5+) partitioning coefficients (D values) from crystal lattice strain models for tetra- and pentavalent proxy ions significantly exceed DPa/DU inferred from direct analysis of 231Pa for Pa5+. This is consistent with predominantly reduced Pa4+ in the melt, for which D values similar to U4+ are expected. Contrary to common assumptions, baddeleyite-crystallizing melts from Vesuvius and Laacher See appear to be dominated by Pa4+ rather than Pa5+. An initial disequilibrium correction for baddeleyite geochronology using DPa/DU = 5 ± 1 is recommended for oxidized phonolitic melt compositions.

Western Marxism

This article others a brief historical account of the complex relationship between Michel Foucault and certain theorists in the Western Marxist philosophical tradition. In the context of the history of the “short twentieth century,” Western Marxism is an intellectual trend based on an interpretation of non-Western revolutionary praxis (by Bolsheviks, Maoists, Guevaristas, etc.). Comparative analysis of several schematic portraits - of Lenin’s revolutionary intellectual, of traditional as opposed to organic intellectuals in Gramsci, and of Foucault’s public intellectual - shows that Foucault in a certain instances was not an external enemy of the Western Marxist tradition, but rather its internal critic. Foucault comes across as a revisionist who engaged in a debate with Lenin about the strategy of the revolutionary movement in France of the 1960s and the 70s. Foucault’s criticism of Leninism unexpectedly turns out to be consistent with the basic struggle of post-WWII Western Marxism to find an alternative to the Bolshevik experience of revolution. This deliberate concurrence makes Foucault one of the significant figures in the history of late Western Marxism, but this becomes a real problem for current historians of neo-Marxist thought when coupled with his generally anti-Marxist views. The article discusses two possible solutions to this problem devised by Perry Anderson and Daniel Bensaid. Anderson’s description of the role of Foucault in the fate of Western Marxism is limited to conceptual questions about the relationship between Marxism and (post) structuralism. Bensaid tries to explain how Foucault fits into the Marxist tradition by appealing to social changes, specifically the changing ideology of capitalist society (in the spirit of The New Spirit of Capitalism by Luc Boltanski and Ève Chiapello). Building on Bensaid’s work, the article shows the link between Foucault’s position on public intellectuals and the crisis of the revolutionary movement of the last half-century, in particular by reference to the famous “Iranian episode” in Foucault’s biography.

Irish Politics

This collection addresses how models from ancient Greece and Rome have permeated Irish political discourse in the century since 1916. The 1916 Easter Rising, when Irish nationalists rose up against British imperial forces, was almost instantly mythologized in Irish political memory as a turning point in the nation’s history and an event that paved the way for Irish independence. Its centenary has provided a natural point for reflection on Irish politics, and this volume highlights an unexplored element in Irish political discourse, namely its frequent reference to, reliance on, and tensions with classical Greek and Roman models. Topics covered include the reception and rejection of classical culture in Ireland; the politics of Irish language engagement with Greek and Roman models; the intersection of Irish literature with scholarship in Classics and Celtic Studies; the use of classical allusion to articulate political inequalities across hierarchies of gender, sexuality, and class; meditations on the Northern Irish conflict through classical literature; and the political implications of neoclassical material culture in Irish society. As the only country colonized by Britain with a pre-existing indigenous heritage of expertise in classical languages and literature, Ireland represents a unique case in the fields of classical reception and postcolonial studies. This book opens a window on a rich and varied dialogue between significant figures in Irish cultural history and the Greek and Roman sources that have inspired them, a dialogue that is firmly rooted in Ireland’s historical past and continues to be ever-evolving.

Tim Groenland's The Art of Editing is an exciting new addition to the field of literary sociology, making a valuable contribution to a discipline which has seen a resurgence since the turn of the millennium. In his seminal early work in the field, John Sutherland traces the origins of this kind of publishing history to Robert Escarpit's Sociology of Literature (1958), which he describes as the beginning of “modern, serious work” in considering the effects of the literary marketplace on the fiction of a particular era. However, it is the first two decades of the twenty-first century that have seen the most significant growth in sociological studies of literary production, a trend that Alan Liu calls “the resurgent history of the book.” This is a “resurgence” that Liu argues has resulted in “restoring to view … vital nodes in the circuit” of literary production, including “editors, publishers, translators, booksellers,” and many others. This recent growth in scholarly interest in the production and circulation of literary texts includes other significant figures such as James F. English, Mark McGurl, John B. Thompson, Loren Glass, Paul Crosthwaite, and David D. Hall.

Do So

A striking feature of Palestinian oral history projects is the extensive use that interviewees make of direct speech to communicate their memories—especially those born before the 1948 Arab–Israeli war. They do so irrespective of whether or not they participated in or actually heard the dialogues they wish to convey. This article seeks to characterize and explain this phenomenon. In the interviews conducted by the author—an Arabic-speaking Jew—as well as in other projects, this mode of speech is marked by ease of transition from character to character and between different points in time. It clearly gives pleasure to those engaged in the act of remembering, and it grades readily into a theatrical performance in which tone of speech and the quality of the acting become the main thing. This form of discourse sprang up from the soil of a rural oral culture and still flourishes as a prop for supporting memory, a vessel for collecting and disseminating stories, and a technique for expressing identification with significant figures from the past.

AbstractThis study draws on the unpublished correspondence between Michelangelo Buonarroti the Younger, a Florentine poet and grandnephew of the artist, and the Barberini family, in an attempt to examine the wider concepts of cultural clientelism and brokerage networks in the early modern process of cultural dissemination (in the areas of literature, music, theater, painting, architecture, and science) in Florence and Rome. Reconsidering the definition and role of a Seicento cultural broker added to the traditional model of patron and client, it analyzes Michelangelo the Younger’s activity as broker, patron-broker, and broker-client in connection with such significant figures as Maffeo Barberini (the future Urban VIII), Galileo, and the painter Lodovico Cigoli, exploring the ways in which these roles supported his personal commitment to promote his family’s social status and revealing the fluidity of roles in the patronage system. By obtaining Barberini patronage for his theatrical works and public recognition of the mythology of his illustrious forebear, Buonarroti’s cultural brokerage supported these dynastic ambitions. Spanning nearly half a century, this archival documentation casts new light on a little-known, but significant, area of Italian social relations and suggests directions for further research on other Seicento cultural brokers and new definitions for a broader concept of cultural brokerage in early modern Italy.

A numerical finite-difference method of calculating the effectiveness for the periodic-flow type heat exchanger accounting for the effect of longitudinal heat conduction in the direction of fluid flow is presented. The method considers the metal stream in crossflow with each of the gas streams as two separate but dependent heat exchangers. To accommodate the large number of divisions necessary for accuracy and extrapolation to zero element area, use was made of a general purpose digital computer. The values of the effectiveness thus obtained are good to four significant figures while those values for the conduction effect are good to three significant figures. The exchanger effectiveness and conduction effect have been evaluated over the following range of dimensionless parameters. 1.0⩾Cmin/Cmax⩾0.901.0⩽Cr/Cmin⩽∞1.0⩽NTU0⩽1001.0⩾(hA)*⩾0.251.0⩾As*⩾0.250.01⩽λ⩽0.32
