Mr Gardner, a practising gynaecologist who is necessarily involved with abortion, suggests a view of the fetus which is between the positions commonly held: the fetus is a mass of cells, the fetus is a person from the moment of conception. He considers that from the moment of conception there is established a maternal-fetal unity. In that state the previable fetus is not an individual but is on the way to that status. The writer goes on to differentiate between (...) the moral positions of the advocates of abortion and of euthanasia. Already legal safeguards for those antipathetic to abortion have been eroded in practice and so likewise would those be if the Euthanasia Bill were to become law. (shrink)

This rich and varied collection of essays addresses some of the most fundamental human questions through the lenses of philosophy, literature, religion, politics, and theology. Peter Augustine Lawler and Dale McConkey have fashioned an interdisciplinary consideration of such perennial and enduring issues as the relationship between nature and history, nature and grace, reason and revelation, classical philosophy and Christianity, modernity and postmodernity, repentance and self-limitation, and philosophy and politics.

The recent article by R. P. Saller on Roman dowry in the Principate makes some interesting and important suggestions about the function of dowry and its role in the devolution of property. I am in broad agreement with a good deal of what he says, and would not dispute his views that dowry was, as shown by the requirement of collatio dotis, regarded as in a sense part of a woman's patrimony, and that the rules for the recovery of dowry (...) show that the purpose of giving dowry was not held to rest on one single principle, but included provision both for the expenses of the wife's maintenance during marriage and for a possible remarriage after divorce or widowhood. However, his remarks on both points need some qualification and amplification. Briefly, I hope to show that the oddities and anomalies noticed by Saller in the rules governing the recovery of dowry at the end of a marriage are apparent rather than real, since these rules rest, not on conflicting views about the purpose of dowry, but on the fact that the husband had full legal ownership of the dowry during marriage, together with the right of the wife or her pater to an actio rei uxoriae for recovery of dowry; that the rules for collatio dotis applied only if the woman herself chose to claim a share in her father's estate on intestacy beyond the amount of her dowry; that the use of the dowry for the wife's support was an equitable, rather than a legal, requirement.

We introduce a linear analogue of Läuchli's semantics for intuitionistic logic. In fact, our result is a strengthening of Läuchli's work to the level of proofs, rather than provability. This is obtained by considering continuous actions of the additive group of integers on a category of topological vector spaces. The semantics, based on functorial polymorphism, consists of dinatural transformations which are equivariant with respect to all such actions. Such dinatural transformations are called uniform. To any sequent in Multiplicative Linear Logic (...) , we associate a vector space of“diadditive” uniform transformations. We then show that this space is generated by denotations of cut-free proofs of the sequent in the theory MLL + MIX. Thus we obtain a full completeness theorem in the sense of Abramsky and Jagadeesan, although our result differs from theirs in the use of dinatural transformations.As corollaries, we show that these dinatural transformations compose, and obtain a conservativity result: diadditive dinatural transformations which are uniform with respect to actions of the additive group of integers are also uniform with respect to the actions of arbitrary cocommutative Hopf algebras. Finally, we discuss several possible extensions of this work to noncommutative logic.It is well known that the intuitionistic version of Läuchli's semantics is a special case of the theory of logical relations, due to Plotkin and Statman. Thus, our work can also be viewed as a first step towards developing a theory of logical relations for linear logic and concurrency. (shrink)

In Chapter 4 of his essay Utilitarianism, “Of what sort of Proof the Principle of Utility is susceptible,” J. S. Mill undertakes to prove, in some sense of that term, the principle of utility. It has very commonly been argued that in the course of this “proof” Mill commits two very obvious fallacies. The first is the naturalistic fallacy which he is held to commit when he argues that since “the only proof capable of being given that an object is (...) visible, is that people actually see it. The only proof that a sound is audible is that people hear it: and so of the other sources of our experience. In like manner … the sole evidence it is possible to produce that anything is desirable, is that people do actually desire it.”1 Here Mill appears to hold that “X is desirable ”—a value judgment—follows deductively from “People desire x”—a factual statement. And the second is the fallacy of composition which seems to be involved in Mill'zs argument that since “each person's happiness is a good to that person … the general happiness, therefore, a good to the aggregate of all persons.”2.

We present a full completeness theorem for the multiplicative fragment of a variant of noncommutative linear logic, Yetter's cyclic linear logic (CyLL). The semantics is obtained by interpreting proofs as dinatural transformations on a category of topological vector spaces, these transformations being equivariant under certain actions of a noncocommutative Hopf algebra called the shuffie algebra. Multiplicative sequents are assigned a vector space of such dinaturals, and we show that this space has as a basis the denotations of cut-free proofs in (...) CyLL + MIX. This can be viewed as a fully faithful representation of a free *-autonomous category, canonically enriched over vector spaces. This paper is a natural extension of the authors' previous work, "Linear Lauchli Semantics", where a similar theorem is obtained for the commutative logic MLL + MIX. In that paper, we interpret proofs as dinaturals which are invariant under certain actions of the additive group of integers. Here we also present a simplification of that work by showing that the invariance criterion is actually a consequence of dinaturality. The passage from groups to Hopf algebras in this paper corresponds to the passage from commutative to noncommutative logic. However, in our noncommutative setting, one must still keep the invariance condition on dinaturals. (shrink)
