In his article ‘A Cavalry Unit in the Army of Antigonus Monophthalmus: Asthippoi’, N. G. L. Hammond argues that the reading of the manuscript R at Diodorus 19. 29. 2 should be retained and that we should read ⋯π⋯ π⋯σι δ⋯ το⋯ς τε ⋯σθ⋯ππους ⋯νομαζομ⋯νους κα⋯ τοὺς ⋯κ τ⋯ν ἄνω κατοικο⋯ντων ⋯κτακοσιο⋯ς. The readings of F and its copy X, ⋯νθ⋯ππους, and the commonly accepted conjecture of Wesseling ⋯μɸ⋯ππους, should both be abandoned. Hammond's arguments for retaining this reading are that (...) between the variant readings of R and F, R ‘is the more often correct’ ; ⋯σθ⋯ππους, the reading of R, is preferable to F's ⋯νθ⋯ππους on the principle of ‘lectio difficilior’; the ‘difficulty’ of his lectio difficilior is made less by the arguments presented by A. B. Bosworth, 245 ff.), for the restoration at several places in the text of Arrian's Anabasis the word ⋯σθ⋯ταιροι, in place of the editorial emendation of πεζ⋯ταιροι. ‘For just as asthetairoi meant an élite group of Macedonian infantrymen,’ says Hammond, ‘so asthippoi should mean an élite group of Macedonian cavalrymen.’ He then proceeds to examine the passage and its context in an attempt to find confirmation of this proposition and comes to the conclusion that Diodorus' text says that there were 800 cavalrymen, broken into two groups, the asthippoi and ‘the men from the up-country settlers’; these, though having different names, had a close relationship to each other, as is shown by their being brigaded together. Following his derivation of asthetairoi as meaning ‘townsmen-companions’, i.e. companions recruited from the towns of Upper Macedonia, he argues that asthippoi were cavalry recruited from the towns of Upper Macedonia and that τοὺς ⋯κ τ⋯ν ἄνω κατοικο⋯ντων means ‘the sons of settlers in up-country Macedonia’. These 800, says Hammond, were both among Antigonus' best troops and ‘were Macedonians from Europe’. We thus appear, on Hammond's interpretation, to have here a group of 800 Macedonian élite cavalrymen, all of whom were recruited in Upper Macedonia's townships, but of whom some were chosen to be the cavalry-equivalent of the élite ‘townsmen-companions’ by their title of ‘townsmen-cavalry’, whilst the others, similarly recruited – but perhaps of a younger generation? – had no particular distinguishing title beyond ‘sons of settlers in up-country Macedonia’.Now, while it would be exciting to be able to add another one, possibly two Macedonian cavalry units to the Macedonian army of Philip, Alexander and the Successors, there are several aspects of Hammond's arguments that, it seems to me, are less than convincing. Thus, whilst it seems beyond reasonable doubt that ⋯σθ⋯ταιροι should be retained in the text of Arrian, appearing, as it does, six times, this is not an argument that ⋯σθ⋯ππους should be read in Diodorus' text. Both it and F's reading of ⋯νθ⋯ππους are hapax legomena and it is possible that both readings are wrong. But even if we retain ⋯σθ⋯ππους as the correct reading, Hammond's explanation of its meaning is open to objection on several counts. (shrink)

"By combining recent advances in the physical sciences with some of the novel ideas, techniques, and data of modern biology, this book attempts to achieve a new and different kind of evolutionary synthesis. I found it to be challenging, fascinating, infuriating, and provocative, but certainly not dull."--James H, Brown, University of New Mexico "This book is unquestionably mandatory reading not only for every living biologist but for generations of biologists to come."--Jack P. Hailman, Animal Behaviour , review of the first (...) edition "An important contribution to modern evolutionary thinking. It fortifies the place of Evolutionary Theory among the other well-established natural laws."--R.Gessink, TAXON. (shrink)

Data from various settings suggest that there is an upper limit of about four on the number of individuals who can interact in spontaneous conversation. This limit appears to be a consequence of the mechanisms of speech production and detection. There appear to be no differences between men and women in this respect, other than those introduced by women’s lighter voices.

Endothelial cells, when cultured on gelled basement membrane matrix exert forces of tension through which they deform the matrix and at the same time they aggregate into clusters. The cells eventually form a network of cord-like structures connecting cell aggregates. In this network, almost all of the matrix has been pulled underneath the cell cords and cell clusters. This phenomenon has been proposed as a possible model for the growth and development of planar vascular systems in vitro. Our hypothesis is (...) that the matrix is reorganized and the cellular networks form as a result of traction forces exerted by the cells on the matrix and the latter's elasticity. We construct and analyze a mathematical model based on this hypothesis and examine conditions necessary for the formation of the pattern. We show cell migration is not necessary for pattern formation and that isotropic, strain-stimulated traction is sufficient to form the observed patterns. (shrink)

While Meinong makes scattered remarks about perception in various writings, the one text in which he makes a concentrated effort to work out a theory of perception is Über die Erfahrungsgrundlagen unseres Wissens (1905). This paper is a critical examination of the theory which is presented there, but also some other texts are taken into account. Special attention will be given to Meinong's views on the object (Gegenstand) of perception, both the propositional object (Objektiv) and the non-propositional object (Objekt) which (...) is allegedly "part" of the propositional object. Also, some contrasts and parallels between these views and those of other members of the Brentano School, e.g. Husserl's notion of categorial perception are discussed. (shrink)

: The introduction of transgenic organisms into agriculture has raised a firestorm of controversy. Many view the technology as a pathway to a much better future society, whereas others condemn it for endangering people and the environment. One defective argument against transgenics is the Unnatural Is Unethical argument (UIU). UIU attempts to prove if transgenic organisms are unnatural and all unnatural things are morally bad, then transgenics are morally bad. However, the argument fails once it is shown that there is (...) no plausible definition for "unnatural." Therefore, UIU should be abandoned in favor of arguments more likely to succeed. (shrink)
