Abstract. During the first half of 20th century, the dominant global tectonics model based on Earth contraction had increasing problems accommodating new geological evidence, with the result that alternative geodynamic theories were investigated. Due to the level of scientific knowledge and the limited amount of data available in many scientific disciplines at the time, not only was contractionism considered a valid scientific theory but the debate also included expansionism, mobilism on a fixed-dimension planet, or various combinations of these geodynamic hypotheses. Geologists and physicists generally accepted that planets could change their dimensions, although the change of volume was generally believed to happen because of a contraction, not an expansion. Constant generation of new matter in the universe was a possibility accepted by science, as it was the variation in the cosmological constants. Continental drift, instead, was a more heterodox theory, requiring a larger effort from the geoscientists to be accepted. The new geological data collected in the following decades, an improved knowledge of the physical processes, the increased resolution and penetration of geophysical tools, and the sensitivity of measurements in physics decreased the uncertainty level in many fields of science. Theorists now had less freedom for speculation because their theories had to accommodate more data, and more limiting conditions to respect. This explains the rapid replacement of contracting Earth, expanding Earth, and continental drift theories by plate tectonics once the symmetrical oceanic magnetic striping was discovered, because none of the previous models could explain and incorporate the new oceanographic and geophysical data. Expansionism could survive after the introduction of plate tectonics because its proponents have increasingly detached their theory from reality by systematically rejecting or overlooking any contrary evidence, and selectively picking only the data that support expansion. Moreover, the proponents continue to suggest imaginative physical mechanisms to explain expansion, claiming that scientific knowledge is partial, and the many inconsistencies of their theory are just minor problems in the face of the plain evidence of expansion. According to the expansionists, scientists should just wait for some revolutionary discovery in fundamental physics that will explain all the unsolved mysteries of Earth expansion. The history of the expanding-Earth theory is an example of how falsified scientific hypotheses can survive their own failure, gradually shifting towards and beyond the limits of scientific investigation until they become merely pseudoscientific beliefs.

As an intellectual tradition, the history of Hegelianism is the history of the reception and influence of the thought of G.W.F. Hegel. This tradition is notoriously complex and many-sided, because while some Hegelians have seen themselves as merely defending and developing his ideas along what they took to be orthodox lines, others have sought to ‘reform’ his system, or to appropriate individual aspects and overturn others, or to offer consciously revisionary readings of his work. This makes it very hard to identify any body of doctrine common to members of this tradition, and a wide range of divergent philosophical views can be found among those who (despite this) can none the less claim to be Hegelians. There are both ‘internal’ and ‘external’ reasons for this: on one hand, Hegel’s position itself brings together many different tendencies (idealism and objectivism, historicism and absolutism, rationalism and empiricism, Christianity and humanism, classicism and modernism, a liberal view of civil society with an organicist view of the state); any balance between them is hermeneutically very unstable, enabling existing readings to be challenged and old orthodoxies to be overturned. On the other hand, the critical response to Hegel’s thought and the many attempts to undermine it have meant that Hegelians have continually needed to reconstruct his ideas and even to turn Hegel against himself, while each new intellectual development, such as Marxism, pragmatism, phenomenology or existential philosophy, has brought about some reassessment of his position. This feature of the Hegelian tradition has been heightened by the fact that Hegel’s work has had an impact at different times over a long period and in a wide range of countries, so that divergent intellectual, social and historical pressures have influenced its distinct appropriations. At the hermeneutic level, these appropriations have contributed greatly to keeping the philosophical understanding of Hegel alive and open-ended, so that our present-day conception of his thought cannot properly be separated from them. Moreover, because questions of Hegel interpretation have so often revolved around the main philosophical, political and religious issues of the nineteenth and twentieth centuries, Hegelianism has also had a significant impact on the development of modern Western thought in its own right. As a result of its complex evolution, Hegelianism is best understood historically, by showing how the changing representation of Hegel’s ideas have come about, shaped by the different critical concerns, sociopolitical conditions and intellectual movements that dominated his reception in different countries at different times. Initially, Hegel’s influence was naturally most strongly felt in Germany as a comprehensive, integrative philosophy that seemed to do justice to all realms of experience and promised to preserve the Christian heritage in a modern and progressive form within a speculative framework. However, this position was quickly challenged, both from other philosophical standpoints (such as F.W.J. Schelling’s ‘positive philosophy’ and F.A. Trendelenburg’s neo-Aristotelian empiricism), and by the celebrated generation of younger thinkers (the so-called ‘Young’ or ‘Left’ Hegelians, such as Ludwig Feuerbach, David Strauss, Bruno Bauer, Arnold Ruge and the early Karl Marx), who insisted that to discover what made Hegel a truly significant thinker (his dialectical method, his view of alienation, his ‘sublation’ of Christianity), this orthodoxy must be overturned. None the less, both among these radicals and in academic circles, Hegel’s influence was considerably weakened in Germany by the 1860s and 1870s, while by this time developments in Hegelian thought had begun to take place elsewhere. Hegel’s work was known outside Germany from the 1820s onwards, and Hegelian schools developed in northern Europe, Italy, France, Eastern Europe, America and (somewhat later) Britain, each with their own distinctive line of interpretation, but all fairly uncritical in their attempts to assimilate his ideas. However, in each of these countries challenges to the Hegelian position were quick to arise, partly because the influence of Hegel’s German critics soon spread abroad, and partly because of the growing impact of other philosophical positions (such as Neo-Kantianism, materialism and pragmatism). Nevertheless, Hegelianism outside Germany proved more durable in the face of these attacks, as new readings and approaches emerged to counter them, and ways were found to reinterpret Hegel’s work to show that it could accommodate these other positions, once the earlier accounts of Hegel’s metaphysics, political philosophy and philosophy of religion (in particular) were rejected as too crude. This pattern has continued into the twentieth century, as many of the movements that began by defining themselves against Hegel (such as Neo-Kantianism, Marxism, existentialism, pragmatism, post-structuralism and even ‘analytic’ philosophy) have then come to find unexpected common ground, giving a new impetus and depth to Hegelianism as it began to be assimilated within and influenced by these diverse approaches. Such efforts at rapprochement began in the early part of the century with Wilhelm Dilthey’s attempt to link Hegel with his own historicism, and although they were more ambivalent, this connection was reinforced in Italy by Benedetto Croce and Giovanni Gentile. The realignment continued in France in the 1930s, as Jean Wahl brought out the more existentialist themes in Hegel’s thought, followed in the 1940s by Alexander Kojève’s influential Marxist readings. Hegelianism has also had an impact on Western Marxism through the writings of the Hungarian Georg Lukács, and this influence has continued in the critical reinterpretations offered by members of the Frankfurt School, particularly Theodor W. Adorno, Max Horkheimer, Herbert Marcuse, Jürgen Habermas and others. More recently, most of the major schools of philosophical thought (from French post-structuralism to Anglo-American ‘analytic’ philosophy) have emphasized the need to take account of Hegel, and as a result Hegelian thought (both exegetical and constructive) is continually finding new directions.

In September 2011, a delicate cargo of 24 Nihoa Millerbirds was carefully loaded by conservationists onto a ship for a three-day voyage to Laysan Island in the remote Northwest Hawaiian Islands. The goal of this effort was to establish a second population of this endangered species, an “insurance population” in the face of the mounting pressures of climate change and potential new biotic arrivals. But the millerbird, or ulūlu in Hawaiian, is just one of the many avian species to become the subject of this kind of “assisted colonisation.” In Hawai'i, and around the world, recent years have seen a broad range of efforts to safeguard species by finding them homes in new places. Thinking through the ulūlu project, this article explores the challenges and possibilities of assisted colonisation in this colonised land. What does it mean to move birds in the context of the long, and ongoing, history of dispossession of the Kānaka Maoli, the Native Hawaiian people? How are distinct but entangled process of colonisation, of unworlding, at work in the lives of both people and birds? Ultimately, this article explores how these diverse colonisations might be understood and told responsibly in an era of escalating loss and extinction.

Strauss's historical investigation of the use of exoteric writing in Farabi, Maimonides, Halevi, and Spinoza, is in fact his history of the philosophers' exoteric accommodations to the permanent difference in human natures, the difference between the many who require a categorical moral teaching and the few who are capable of ordering their own lives in the face of the hypothetical status of all moral commands. The men of the Enlightenment aspired to render the moral law superfluous for all by constructing a machinery of government powerful enough to compel all to live justly. Strauss critiques this aspiration by leading his reader to face the permanency of the difference between the few and the many. Strauss uses historical scholarship to force the reader to rethink the possibility of contemplation of the eternal or permanent, the possibility that the Enlightenment's historicist epigones have sought to foreclose.

Alfred Wegener never set out to be a geologist. With an education in meteorology and astronomy, his career seemed clear when he was appointed Lecturer in those subjects at the University of Marburg, Germany. It wasn’t until 1912, when Wegener was 32, that he published a paper titled “Die Entstehung der Kontinente” (The origin of the continents) in a recently founded journal called Geologische Rundschau. This meteorologist had just fired the opening shot in a revolution that would change the way that geologists thought about the earth. In a series of publications and talks both before and after World War I, Wegener pressed the idea that continents moved around the earth independently of each other and that the present continents resulted from the splitting of a large landmass (we now call it a “supercontinent”) that previously contained all of the world’s continents. After splitting, they moved to their current positions, closing oceans in front of them and opening new oceans behind them. Wegener and his supporters referred to this process as “continental drift.” The proposal that continents moved around the earth led to a series of investigations and ideas that occupied much of the 20th century. They are now grouped as a set of concepts known as “plate tectonics.” We begin this chapter with an investigation of the history of this development, starting with ideas that preceded Wegener’s proposal. This is followed by a section that describes the reactions of different geologists to the idea of continental drift, including some comments that demonstrate the rancorous nature of the debate. The next section discusses developments between Wegener’s proposal and 1960, when Harry Hess suggested that the history of modern ocean basins is consistent with the concept of drifting continents. We finish the chapter with a brief description of seafloor spreading and leave a survey of plate tectonics to chapter 2. Although Wegener is credited with first proposing continental drift, some tenuous suggestions had already been made. We summarize some of this early history from LeGrand (1988).

This chapter describes the evolution of the role of the UN Secretary-General in the context of international relations, paying particular attention to the historical origins of the office within the international civil service. It explores the challenges faced by the Secretary-General in seeking to act independently on behalf of the global interest, in a political environment characterized by competing national interests and power politics. It also considers whether the process that resulted in the appointment of António Gutteres in 2016—seen as the most transparent, meritocratic, and inclusive in the history of the UN—might enable the Secretary-General to be more effective in the face of the many pressures upon the office.

The topic of this paper is social constructivist doctrines about the nature of scientific knowledge. I don't propose to review all the many accounts that have either claimed this designation or had it ascribed to them. Rather I shall try to consider in a very general way what sense should be made of the underlying idea, and then illustrate some of the central points with two central examples from biology. The first thing to say is that, on the face of it, some doctrine of the social construction of science must self-evidently be true. The notion of science as progressing through the efforts of solitary geniuses may have had some plausibility in the seventeenth century, but it has none today. Science is a massively cooperative, social, enterprise. And surely it is constructed. Scientific knowledge doesn't grow on trees; it is produced through hard work by human agents. Putting these two banal points together we conclude that science is socially constructed.


Both the concepts of plate tectonics and continental drift conceive that the planet earth’s dimension, associated with its oceans, has remained unchanged throughout the past geological periods. In contrast, Hilgenberg’s model of earth expansion endorses that initially the planet was considerably small and devoid of oceans [1]. Based on earth expansion theory the author has pointed out that since the primordial condensed or small earth was devoid of oceans, initially the ocean-forming water must have been associated with the mantle, thereby turning that geosphere considerably fluid and pre-eminently suitable for planetary expansion. Expansion of the planet appears to have been caused owing to swelling up of the semi-fluid mantle in response to an external gravitational pull caused by an extra-terrestrial planetary body, probably the Moon. The primordial earth was completely covered with a relatively thin granitic crust, which, due to swelling up of the mantle developed a number of long and sinuous expansion cracks. Through these expansion cracks widespread eruption of molten magma took place spreading on both sides of the cracks to form rudimentary oceans basins. With continued expansion, the dimension of the oceans was broadened while the expansion cracks turned in to mid-oceanic ridges. Associated with expulsion of molten lava, large quantum of volatiles, chiefly constituted of water was released from the mantle that formed the ocean water while due to desiccation of the mantle, the process of expansion was eventually stopped.

Abstract. In a recent article in this journal, Paolo Sudiro (2014) considered the long history of the expanding Earth theory and its recent descent into what he termed “pseudoscientific belief”. The expanding Earth theory contends that the radius of the Earth was once one-half to two-thirds of its current value, with the Earth's continents forming a continuous sialic cover over the Earth. The theory has had two main variants: slow expansion at about 0.5 mm yr−1 radial increase since the time of Earth's formation and fast expansion at about 5 mm yr−1 since the Triassic. Focusing on Maxlow's model, Sudiro thoroughly addresses the possibly insurmountable difficulties of the fast version, such as an improbably high density and surface gravity prior to 200 Ma. He omits, however, any discussion of the slow expansion model, which has a longer history and far fewer theoretical difficulties. Moreover, recent evidence from space geodesy, gravimetry and seismology indicates that the Earth at present may be slowly expanding at 0.1–0.4 mm yr−1. It is concluded that Sudiro's obituary of the expanding Earth theory as a whole must be considered premature at this time.

 The blog site of the Oxford Dictionaries features a post dated November 16 2015, which announces that, “for the first time ever”, their “Word of the Year” is not a word, but a pictograph: the “Face with Tears of Joy” emoji. The term emoji, which is a loanword from Japanese, identifies “a small digital image or icon used to express an idea or emotion in electronic communication” (OED 2015). The sign was chosen since it is the item that “best reflected the ethos, mood, and preoccupations of 2015”. Indeed, the Oxford Dictionaries’ President, Caspar Grathwohl declared that emojis are “an increasingly rich form of communication that transcends linguistic borders” and reflects the “playfulness and intimacy” of global digital culture. Adopting a socio-semiotic multimodal approach, the present paper aims at decoding the many semantic and semiotic layers of the 2015 “Word of the Year”, with a special focus on the context of cultures out of which it originates. More in detail, the author will focus on the concept of translation as “transduction”, that is the movement of meaning across sign systems (Kress 1997), in order to map the history of this ‘pictographic word’ from language to language, from culture to culture, from niche discursive communities to the global scenario. Indeed, the author maintains that this ‘pictographic word’ is to be seen as a marker of the mashing up of Japanese and American cultures in the discursive practices of geek communities, now gone mainstream thanks to the spreading of digital discourse.

The ‘United Church of England and Ireland’, established by the Act of Union ‘for ever’ as ‘an essential and fundamental part of the Union’, survived less than seventy years. N. D. Emerson, in his 1933 essay on the church in this period, presented the history of the church in the first half of the nineteenth century as ‘the history of many separate interests and movements’; he suggested a thesis of fundamental importance in the historiography of the Church of Ireland: Beneath the externals of a worldly Establishment, and behind the pomp of a Protestant ascendancy, was the real Church of Ireland, possessed of a pure and reformed faith more consciously grasped as the century advanced and labouring to present its message in the face of apathy and discouragement, as well as of more active and hostile opposition.Recent historical work has begun to trace the ‘many separate interests and movements’ and to explore in detail both the ‘worldly Establishment’ and the increasingly predominant evangelical influence of the Church of Ireland during the post-union period. The main topics investigated have been the structure of the church, the political relationships of the church, the evangelical movement, the mentalities of various social groups (drawing upon literary sources), and local or regional studies. The numerous gaps in the research and in our knowledge which exist seem now all the starker given the high quality of so many recent studies concerning the Church of Ireland in this period.
