This classic collection of essays, first published in 1968, represents H.L.A. Hart's landmark contribution to the philosophy of criminal responsibility and punishment. Unavailable for ten years, this new edition reproduces the original text, adding a new critical introduction by John Gardner, a leading contemporary criminal law theorist.

A representation is a remnant of previous experience that allows that experience to affect later behavior. This paper develops a metatheoretical view of representation and applies it to issues concerning representation in animals. To describe a representational system one must specify the following: thedomainor range of situations in the represented world to which the system applies; thecontentor set of features encoded and preserved by the system; thecodeor transformational rules relating features of the representation to the corresponding features of the represented (...) world; themedium, or the representation's physical instantiation; and thedynamics, or how the system changes with time. In part because of the behaviorist assumption that the hypothetical, covert changes occurring in an organism during learning correspond to the overt physical changes that are observed, issues of representation in animal behavior have been largely ignored as irrelevant or misleading. However, it can be inferred that representations, acting as models of environmental regularities, operate at many levels of behavioral functioning, both cognitive and noncognitive. Objections to the use of this concept in explanations of animal behavior, based on the claim that it is indeterminate and on behaviorist considerations of parsimony, can be answered. Animal representations may be specialized in terms of tasks and species. Data from tasks involving spatial memory, delayed matching-to-sample, and sequence learning suggest some foundations for a general theory of animal representations. (shrink)

In his introduction to these closely linked essays Professor Hart offers both an exposition and a critical assessment of some central issues in jurisprudence and political theory. Some of the essays touch on themes to which little attention has been paid, such as Bentham's identification of the forms of mysitification protecting the law from criticism; his relation to Beccaria; and his conversion to democratic radicalism and a passionate admiration for the United States.

This incisive book deals with the use of the criminal law to enforce morality, in particular sexual morality, a subject of particular interest and importance since the publication of the Wolfenden Report in 1957. Professor Hart first considers John Stuart Mill's famous declaration: "The only purpose for which power can be rightfully exercised over any member of a civilized community is to prevent harm to others." During the last hundred years this doctrine has twice been sharply challenged by two great (...) lawyers: Sir James Fitzjames Stephen, the great Victorian judge and historian of the common law, and Lord Devlin, who both argue that the use of the criminal law to enforce morality is justified. The author examines their arguments in some detail, and sets out to demonstrate that they fail to recognize distinction of vital importance for legal and political theory, and that they espouse a conception of the function of legal punishment that few would now share.

The European Union welfare standardsfor intensively kept pigs have steadilyincreased over the past few years and areproposed to continue in the future. It isimportant that the cost implications of thesechanges in welfare standards are assessed. Theaim of this study was to determine theprofitability of rearing pigs in a range ofhousing systems with different standards forpig welfare. Models were constructed tocalculate the cost of pig rearing (6–95 kg) in afully-slatted system (fulfilling minimum EUspace requirements, Directive 91630/EEC); apartly-slatted system; a high-welfare,straw-based system (...) (complying with the UK-basedRoyal Society for the Prevention of Cruelty toAnimals, Freedom Food standards) and afree-range system. The models were also used toassess the consequences of potential increasesin space allowance, and to estimate the cost ofrearing pigs under organic standards.The cost of rearing pigs ranged from92.0 p/kg carcass weight (cw) and 94.6 p/kgcw forthe partly-slatted and fully-slatted systems,to 98.8 p/kgcw and 99.3 p/kgcw for the FreedomFood and free-range systems respectively. Whenspace allowance was increased by 60% to levelsin a recent proposal to revise pig welfareDirective (91/630/EEC), the rearing costs wereunchanged for the free-range system but rose by4.6 p/kgcw for the fully-slatted system. Rearingcosts under organic standards were 31% higherthan in the free-range system. These resultssuggest that improved pig welfare can beachieved with a modest increase in cost. (shrink)

The twelfth century was a period of transmission and absorption of Arabic learning though it filtered outside of the Arabic world as early as the second half of the tenth century. In general, the lure of Spain began to act only in the twelfth century, and the active impulse toward the spread of Arabic mathematics came from beyond the Pyrenees and from men of diverse origins. The chief names are Adelard of Bath, Robert of Chester, Hermann of Carinthia and Gerard (...) of Cremona. In this time the Latin world became acquainted with the Hindu numerals, the Arabic Algebra and Euclid'sElements. However, not only Spain, but also the Norman kingdom of southern Italy and Sicily occupies a position of peculiar importance, though the works of the translators did not become very influential. There were made direct translations from Greek into Latin. One had to wait a century more to obtain a translation from Greek into Latin of the chief Archimedean scientific and mathematical treatises by William of Moerbeke. In the thirteenth century Fibonacci and Jordanus Nemorarius stand at the threshold of European mathematics. Not only was Fibonacci the first to explain Arabic arithmetic, but his works, especially his later ones, contain many original ideas. Jordanus continued the Greco-Roman tradition rather than the Greco-Arabic one, but he did so with much independence. To Nicole Oresme (fourteenth century) was due a broadened view of proportionality, a geometric proof to determine the summation of convergent infinite series and the proof, evidently the first in the history of mathematics, that the harmonic series is divergent. The Configuration Doctrine was treated by Merton College authors and by Oresme. In the fifteenth century theDe triangulis omnimodis of Regiomontan, a systematic account of the methods for solving triangles, marked the rebirth of trigonometry. (shrink)

Im folgenden sollen zwei Arbeiten zur theoretischen Mathematik vorgestellt werden, die im 14. Jahrhundert entstanden. Die eine stammt von Thomas Bradwardine (um 1290 - 1349), einem der wichtigsten Mathematiker dieser Zeit, die andere von dem praktisch unbekannten Wigandus Durnheimer. Bei Bradwardine soll insbesondere die Frage beantwortet werden, welche der arithmetischen Schriften, die ihm zugeschrieben werden, wirklich von ihm stammt. Bei Durnheimers Schrift, einer Kompilation, die u.a. auf Bradwardines Abhandlung beruht, werden der Inhalt der einzelnen Kapitel und deren Quellen angegeben.
