Living things are often plastic during their early development and are moulded by the environment. Many human fetuses have to adapt to a limited supply of nutrients, and in doing so they permanently change their physiology and metabolism. These programmed changes may be the origins of a number of diseases in later life, including coronary heart disease, stroke, diabetes and hypertension.

The achievements of the textile industry in Roman Britain are often underestimated as a result of the meagreness of our available evidence. The Edict on maximum prices issued by Diocletian in A.D. 301 shows that British capes commanded high prices on the markets of the Empire, and that in the late third century A.D. British rugs were the best in the world. In view of the competition from the traditional centres of rug manufacture in the East, this is an astonishing (...) achievement. (shrink)

We isolate two abstract determinacy theorems for games of length $\omega_1$ from work of Neeman and use them to conclude, from large-cardinal assumptions and an iterability hypothesis in the region of measurable Woodin cardinals thatif the Continuum Hypothesis holds, then all games of length $\omega_1$ which are provably $\Delta_1$ -definable from a universally Baire parameter are determined;all games of length $\omega_1$ with payoff constructible relative to the play are determined; andif the Continuum Hypothesis holds, then there is a model of (...) ${\mathsf{ZFC}}$ containing all reals in which all games of length $\omega_1$ definable from real and ordinal parameters are determined.

It is shown that the determinacy of $G_{\delta \sigma }$ games of length $\omega ^2$ is equivalent to the existence of a transitive model of ${\mathsf {KP}} + {\mathsf {AD}} + \Pi _1\textrm {-MI}_{\mathbb {R}}$ containing $\mathbb {R}$. Here, $\Pi _1\textrm {-MI}_{\mathbb {R}}$ is the axiom asserting that every monotone $\Pi _1$ operator on the real numbers has an inductive fixpoint.

Shepherdson [14] showed that for a discrete ordered ring I, I is a model of IOpen iff I is an integer part of a real closed ordered field. In this paper, we consider integer parts satisfying PA. We show that if a real closed ordered field R has an integer part I that is a nonstandard model of PA (or even IΣ₄), then R must be recursively saturated. In particular, the real closure of I, RC (I), is recursively saturated. We (...) also show that if R is a countable recursively saturated real closed ordered field, then there is an integer part I such that R = RC(I) and I is a nonstandard model of PA. (shrink)

1. The Commentariolum Petitionis is not in the Codex Mediceus of Cicero's correspondence with his brother Quintus, but it appears at the end of the letters to Quintus in the other manuscripts. It starts in the normal manner of a letter and is, or purports to be, a collection of tips on canvassing set in the particular context of M. Cicero's consular candidature in 64: a composition of his brother Quintus. It is printed as no. 12 in Tyrrell and Purser's (...) collection of Cicero's Letters. (shrink)

As inductive logic and the philosophy of probability theory have become of wider interest, it has become clear that a book of readings in these and related topics would be useful for courses since most of the important articles are scattered and inaccessible. The editors have fashioned an extensive collection of papers in four main areas: the meaning of probability, confirmation theory, simplicity of theories and structures, the justification of induction. Each chapter is preceded by an introduction which sets out (...) the basic problems of the topic under consideration. There are thirty-six papers in all, two-thirds of them in the first and last chapters. The first chapter includes articles by Ramsey, Carnap, Nagel, and Reichenbach. The second chapter is dominated by the work of Hempel, Oppenheim, and Kemeny; the third chapter features a long article by D. J. Hillman which takes as its basis the work of Goodman, and there are other papers by Bunge, Quine, and Barker. The discussion of induction and its justification contains articles by Hume and Mill, but the bulk of the papers are contemporary. There is a bibliography for each chapter at the end of the book.—P. J. M. (shrink)

Of the early Roman historians who wrote in Greek, A. Postumius Albinus was not necessarily alone in realizing that his Greek was not the best Greek; while, on the other hand, Cato and those who followed the new fashion of writing in Latin would have resented, we may assume, could they have foreknown, the statement of Q,. Catulus in Cicero's De Oratore that they had no literary or rather ‘oratorical’ merit; though Cato might have approved Catulus' caustic comment on Roman (...) historical writing, ‘Satis est non esse mendacem’. That an historian should not, consciously and deliberately, lie all second-century historians would no doubt have agreed; and they would have endorsed Polybius' condemnation of masquerading as history in a story whose falseness was self-evident, because it assumed, on the part of the young sons of senators at Rome, a gravitas such as no young boy could possibly possess.

Compelled by recent public and politicized cases in which withdrawal of nutrition and hydration were at issue, this essay examines recent Church statements and argues that the distinction between private and public forms of human life is being lost. Effacing the distinction between the sphere of the home (oikos), where the maintenance of life (zoē) occurs, and the city (polis), where political and public life (bios) occurs, may have unforeseen and unwanted consequences. Through their well-intentioned efforts to preserve the sanctity (...) of life, certain bishops and the Congregation for the Doctrine of the Faith have unfortunately brought political considerations into the home, taking decision-making authority away from those most intimately related to the patient. Thus, the question of removing nutrition and hydration in the case of patients such as Schiavo and Englaro becomes politicized and abstract, in contrast with the Church's previous positions on the importance of proportionate means in the maintenance of life, local decision making, and its recognition of life as a penultimate end.

‘Auctoritas’ was naturally one of Cicero's favourite concepts. In the ideal republic power lay with the people, auctoritas with the Senate . Alternatively, in a balanced state, potestas would lie with the magistrates, libertas with the people, but still auctoritas would be the property of the Senate, ‘in principum consitio’ [De rep. 2. 57).
