We have developed a formal model of certain types of riddles, and implemented it in a computer program, JAPE, which generates simple punning riddles. In order to test the model, we evaluated the behaviour of the program, by having 120 children aged eight to eleven years old rate JAPE-generated texts, human-generated texts, and non-joke texts for "jokiness" and funniness. This confirmed that JAPE's output texts are indeed jokes, and that there is no significant difference in funniness or jokiness between JAPE"s (...) most comprehensible texts and published human-generated jokes.

Over recent decades there has been a growing interest in the question of whether computer programs are capable of genuinely creative activity. Although this notion can be explored as a purely philosophical debate, an alternative perspective is to consider what aspects of the behaviour of a program might be noted or measured in order to arrive at an empirically supported judgement that creativity has occurred. We sketch out, in general abstract terms, what goes on when a potentially creative program is (...) constructed and run, and list some of the relationships (for example, between input and output) which might contribute to a decision about creativity. Specifically, we list a number of criteria which might indicate interesting properties of a program’s behaviour, from the perspective of possible creativity. We go on to review some ways in which these criteria have been applied to actual implementations, and some possible improvements to this way of assessing creativity. (shrink)

ObjectiveThe Spatial Learning Task of Lhermitte and Signoret is an object-location arbitrary associative learning task. The task was originally developed to evaluate adults with severe amnesia. It is currently used in populations where the memory system either is not yet fully developed or where it has been compromised (e.g. epilepsy, traumatic brain injury, electroconvulsive therapy, cerebrovascular disease and dementia). Normative data have been published for paediatric cohorts and for older adults, however no data exist for the intervening adult years.MethodHere, we (...) address this gap, collecting normative data from 101 adults aged 18–45.ResultsOur data indicate that performance on the Spatial Learning Task is not influenced by age, gender, level of education or overall IQ. Less than 10% of the variance in learning scores is associated with variability in verbal memory. Ninety percent of participants achieved perfect scores on two successive trials (T2Cr) within five or fewer trials on the Spatial Learning Task. A T2Cr score of 6 is suggestive of impairment and a T2Cr score of 7 or more is statistically abnormal.ConclusionThese data expand the clinical utility of the Spatial Learning Task in the adult population. Future work should examine performance in lower IQ cohorts, including intellectual disability, and explore sensitivity to disease factors such as laterality of mesial temporal lobe damage. (shrink)

This article explores the role of surface ambiguities in referring expressions, and how the risk of such ambiguities should be taken into account by an algorithm that generates referring expressions, if these expressions are to be optimally effective for a hearer. We focus on the ambiguities that arise when adjectives occur in coordinated structures. The central idea is to use statistical information about lexical co-occurrence to estimate which interpretation of a phrase is most likely for human readers, and to avoid (...) generating phrases where misunderstandings are likely. Various aspects of the problem were explored in three experiments in which responses by human participants provided evidence about which reading was most likely for certain phrases, which phrases were deemed most suitable for particular referents, and the speed at which various phrases were read. We found a preference for ‘‘clear’’ expressions to ‘‘unclear’’ ones, but if several of the expressions are ‘‘clear,’’ then brief expressions are preferred over non-brief ones even though the brief ones are syntactically ambiguous and the non-brief ones are not; the notion of clarity was made precise using Kilgarriff's Word Sketches. We outline an implemented algorithm that generates noun phrases conforming to our hypotheses. (shrink)

There are many possible ways of approach to philosophy, and there is also an impossible one, though one that has often been tried. That the philosopher can somehow spin his philosophy out of what he finds inside himself; that he has some private internal source of information in virtue of which he can decide what the Universe must be, without needing to take the trouble to look at it, is a belief that dies hard. But it is now dying, if (...) not dead, so that it is hardly necessary to refute it in detail. It should suffice to say that anybody who cherishes the belief will not find anything to interest him in what follows. I shall simply assume that the philosopher is, what we all are to some extent, a spectator of the world and of man's life in it and a commentator on what he sees. Where the philosopher differs from others is in the kind of interest he takes in the facts, not in the kind of facts that are there to be interested in. (shrink)

Analytic philosophy has recently demonstrated a revived interest in metaphysical problems about possibility and necessity. Graeme Forbes here provides a careful description of the logical background of recent work in this area for those who may be unfamiliar with it, moving on to d discuss the distinction between modality de re and modality de dicto and the ontological commitments of possible worlds semantics. In addition, Forbes offers a unified theory of the essential properties of sets, organisms, artefacts, substances, and (...) events, based on the doctrine that identity facts must be intrinsically grounded, and analyzes and rejects apparent counterexamples to this doctrine.

Everybody is to some extent pacific, as everybody prefers to attain his ends by peaceful means if he can. Even the most bloodthirsty militarist uses threats of war rather than war, if threats will do the work. Though most people prefer persuasion to violence and peace to war, they are prepared as a last resort to go to war and use violence, when that seems the only means to attaining some end they consider to be of vital importance. The one (...) hundred per cent pacifist, however, refuses to engage in war or support warlike action under any circumstances whatever. It is his case that I wish to consider. It is not my purpose to try to persuade anyone to be a pacifist or to be the opposite, but to point out that absolute pacifism carries with it certain logical consequences which are not particularly palatable. The opposed view, which I shall call the case for civic virtues, also carries unpalatable though different consequences. These two appear to be simple and clear-cut opposed views which I propose to state as fairly as I can, with their consequences. Certain qualifications and modifications will have to be considered later, but I do not think that there is actually any possible mean position which avoids the dilemma I am concerned to present. I shall state the case for civic virtue first and the pacifist case second. (shrink)

Positivists have excelled at destructive criticism. This criticism has been useful for pruning away absurd and superfluous theories but it is liable to be used to prune away everything else. The latest exponents, the Logical Positivists, are no less adept at criticism than their predecessors. The doctrines of this school have been surrounded with an air of mystery and inquirers have been frightened off by alarming technical apparatus. We all know that the Logical Positivists had proved that everybody else talked (...) nonsense, but we did not know what they themselves talked. Mr. A. J. Ayer's exposition of the doctrine, Language, Truth and Logic , is therefore welcome as it is simple. (shrink)

Those who have advocated belief in immortality have often spoiled their case by arguing for different theories without realizing that they were different. Those who have opposed the belief have been apt to think that when they had disposed of one theory they had done all they set out to do. The first condition for clarity of thought on the subject is therefore to distinguish the different types of theory which have been put forward. This is my primary aim in (...) the following discussion. If, in the course of it, I speak more favourably of one theory and less favourably of others, it must be understood that this bias is incidental to my present theme, which is to examine assertions rather than to assert.

The claims that Dr. F. H. George makes on behalf of his machines are obscurely stated. Does he claim that a machine has been made and has actually produced a kind of response which is incalculable, given the specification to which it has been built and also the prescribed conditions, what is put in for the particular performance in question? “Incalculable” does not mean that nobody has bothered to calculate, but that somebody has bothered, that the calculations show that the (...) response in question is not among the calculated ones, that it is not chance or mechanical breakdown, but a specific response to something specific among the given conditions. If he could substantiate this claim, then I would reluctantly agree that some machines are cleverer and more thoughtful than I thought possible, and some men sillier and less thoughtful, for they deliberately design machines to do they know not what.

There is a short answer to the question, whether scientific method can be applied to the study of the social relations of men, or, whether social sciences are possible; it is that these sciences exist and are in fact among the most ancient. Their success has perhaps been less startling than that of the physical sciences and they have perhaps been pursued with less enthusiasm. But there are reasons for this inherent in the nature of the social sciences, as I (...) shall try to show. (shrink)

In this provocative work, noted social and economic theorist Graeme D. Snooks exposes fatal flaws in the foundations of the Darwinian theory of evolution. Further, he develops a remarkable replacement theory of evolution. The new 'dynamic-strategy' theory views life as a strategic pursuit in which organisms adopt dynamic strategies to survive and prosper. This theory reveals the organism as empowered, rather than as the plaything of gods, genes, or blind chance. And it provides a powerful new basis for humanism.

This erudite book is aimed more directly at specialists in theories of right and law, than at Leibniz scholars. Acknowledging a debt of inspiration to the remarkable historical work of André de Muralt, the author introduces in variable detail the legal philosophy of Suarez, Grotius, Pufendorf, Hobbes, Locke, Berkeley, and Kant, with substantial forays into Augustine, Aquinas, Scotus and Ockham. Leibniz fits into this study less as its raison d’être than as a piece in the puzzle, one local system of (...) thought amid the galaxy of the modern school of natural right. (shrink)
