Egypt has not yet given us a Greek original of Plautus, unless the paltry Hibeh fragments belong to the original of the Aulularia. If they do, then Plautus departed widely from the Greek. And that is what one would expect. Read any ‘sermo’ in Plautus and see how recklessly he abandons himself to the vagaries of his humour. Clearly no ‘icily regular’ Greek is his guide there. Still a ray of light has come from Egypt that illumines one dark spot (...) in Plautus, the end of the first Scene of the Bacchides. The two sisters retreat into the house after a line which appears in our editions in this form. (shrink)

This paper gives a simple, elegant statement of the condensed detachment rule that is independent of most general unifiers and proves that this is equivalent to the longer, more usual, formulation.

The passing on of information to GPs by genito-urinary doctors is to be encouraged but is not always possible and ultimately the patient's wishes and confidentiality must be respected if sexually transmitted diseases and HIV infection are to be controlled. Infected health-care workers should seek counselling and medical support and clear guidelines from professional organisations which are in existence. However, they will only do so if strict confidentiality is maintained and assurance about future employment can be given.

Written in a relaxed, readable style, A Concise Introduction to Pure Mathematics leads students gently but firmly into the world of higher mathematics. It provides beginning undergraduates with a rigourous grounding in the basic tools and techniques of the discipline and prepares them for further more advanced studies in analysis, differential equations, and algebra. This edition contains additional material on secret codes, permutations, and prime numbers. It features more than 200 exercises, with many completely new. The text is organized into (...) relatively independent chapters, allowing instructors to tailor the book to meet their individual course needs. · Contains extra material concerning prime numbers, forming the basis for data encryption · Explores "Secret Codes" - one of today's most spectacular applications of pure mathematics Discusses Permutations and their importance in many topics in discrete mathematics.

An attitude which hopes to derive aesthetic pleasure from an object is often thought to be in tension with an attitude which hopes to derive knowledge from it. The current article argues that this alleged conflict only makes sense when the aesthetic attitude and knowledge are construed unnaturally narrowly, and that when both are correctly understood there is no tension between them. To do this, the article first proposes a broad and satisfying account of the aesthetic attitude, and then considers (...) and rejects twelve reasons for thinking that deriving knowledge from something is incompatible with maintaining an aesthetic attitude towards it. Two main conclusions are drawn. 1) That the representational arts are often in a good position to communicate non-propositional knowledge about human beings. 2) That while our desire to obtain pleasure from a work's manifest properties, and our desire to obtain knowledge from it, are not the same motive, the formal similarities between them are sufficiently impressive to warrant both being seen as elements of the aesthetic attitude.

The Birkhoff-Maltsev problem asks for a characterization of those lattices each of which is isomorphic to the lattice L(K) of all subquasivarieties for some quasivariety K of algebraic systems. The current status of this problem, which is still open, is discussed. Various unsolved questions that are related to the Birkhoff-Maltsev problem are also considered, including ones that stem from the theory of propositional logics.
