Marcus et al.’s experiment (1999) concerning infant ability to distinguish between differing syntactic structures has prompted connectionists to strive to show that certain types of neural networks can mimic the infants’ results. In this paper we take a closer look at two such attempts: Shultz and Bale [Shultz, T.R. and Bale, A.C. (2001), Infancy 2, pp. 501–536] Altmann and Dienes [Altmann, G.T.M. and Dienes, Z. (1999) Science 248, p. 875a]. We were not only interested in how well these two models (...) matched the infants’ results, but also whether they were genuinely learning the grammars involved in this process. After performing an extensive set of experiments, we found that, at first blush, Shultz and Bale’s model (2001) replicated the infant’s known data, but the model largely failed to learn the grammars. We also found serious problems with Altmann and Dienes’ model (1999), which fell short of matching any of the infant’s results and of learning the syntactic structure of the input patterns. (shrink)

Aldo Leopold was a pragmatist in the vernacular sense of the word. Bryan G. Norton claims that Leopold was also heavily influenced by American Pragmatism, a formal school of philosophy. As evidence, Norton offers Leopold's misquotation of a definition of right (as truth) by political economist, A.T. Hadley, who was an admirer of the philosophy of William James. A search of Leopold's digitised literary remains reveals no other evidence that Leopold was directly influenced by any actual American Pragmatist or (...) by Pragmatism (although he may have been indirectly influenced by Pragmatism early in his career). A 1923 reference, by Leopold, to Hadley and Hadley's putative definition of truth, cited by Norton, is dripping with irony. Leopold, as he matured philosophically, regarded a profound cultural shift from anthropocentric dominionism and consumerism to an evolutionary-ecological worldview and an associated non-anthropocentric 'land ethic' to be necessary for successful and sustainable conservation. Hadley espoused a brutal form of Social Darwinism and his philosophy, as expressed in the book of Hadley's that Norton cites, is politically reactionary, militaristic and unconcerned with conservation. Leopold's mature philosophy and Hadley's – far from consonant, as Norton claims – are diametrically opposed. (shrink)

T. A. Cavanaugh defends double-effect reasoning, also known as the principle of double effect. DER plays a role in anti-consequentialist ethics, in hard cases in which one cannot realize a good without also causing a foreseen, but not intended, bad effect. This study is the first book-length account of the history and issues surrounding this controversial approach to hard cases. It will be indispensable in theoretical ethics, applied ethics, and moral theology. It will also interest legal and public policy scholars.

For many commentators, Confucian ethics is a kind of virtue ethics. However, there is enough textual evidence to suggest that it can be interpreted as an ethics based on rules, consequentialist as well as deontological. Against these views, I argue that Confucian ethics is based on the roles that make an agent the person he or she is. Further, I argue that in Confucianism the question of what it is that a person ought to do cannot be separated from the (...) question of what it is to be a person, and that the latter is answered in terms of the roles that arise from the network of social relationships in which a person stands. This does not mean that Confucian ethics is unlike anything found in Western philosophy. Indeed, I show that many Western thinkers have advanced a view of ethics similar to the Confucian ethics as I interpret it. (shrink)

In three experiments, the relation between different modes of thought and the generation of “creative” and original ideas was investigated. Participants were asked to generate items according to a specific instruction . They either did so immediately after receiving the instruction, or after a few minutes of conscious thought, or after a few minutes of distraction during which “unconscious thought” was hypothesized to take place. Throughout the experiments, the items participants listed under “unconscious thought” conditions were more original. It was (...) concluded that whereas conscious thought may be focused and convergent, unconscious thought may be more associative and divergent. (shrink)

"While ancient Greek thought is widely acknowledged as the major source of political ideals such as freedom and equality, ancient Greek practices including slavery, the subordination of women, and imperialism have been condemned as undemocratic and immoral. So is ancient Greek political thought still relevant today? In this wide-ranging history, Ryan Balot shows what ancient Greek political texts might mean to citizens of the twenty-first century."--BOOK JACKET.

In lieu of an abstract, here is a brief excerpt of the content:39 HUME'S JUSTICE AS A COLLECTIVE GOOD David Hume would probably regard his 'system of morals' as the most important part of his treatise of human nature. Yet his moral theory, particularly his theory of justice, continues to baffle commentators. Many have found it difficult to follow his line of reasoning to the conclusions that it is an artificial virtue to obey the rules of justice, and that such (...) rules command our respect even though we do not have any natural tendencies to respect them. The most troubling claim seems to be the claim that justice is ultimately based on self-interest, the motive that, on the surface at least, tends to induce people to ignore justice, particularly justice of the kind Hume is talking about. Jonathan Harrison, for instance, goes through a series of examples in an attempt to get close to Hume's meaning. In this paper I wish to argue that by justice Hume has in mind something very much like what modern economists call collective good. In the economic theory of public finance, which was born in the late Fifties, a distinction is made between collective goods and private goods. I wish to argue that this distinction can be employed to elucidate the nature of Hume's concept of justice, as well as to pinpoint the source of the moral force making justice a virtue rather than just a matter of prudence. I Most goods (and services) bought and sold in any economy have the following characteristics. First, as one person purchases (and consumes) a quantity of a particular good, there is less of it available for others to consume (that is, before more is produced). If the market is cleared (i.e. all that is produced is bought and sold), the total production or supply (X_, say) is the sum of individual purchases (X =X +X + etc.). 40 Second, the benefit of consumption is confined largely to the person who consumes the good. The overall benefit is said to be divisible among consumers. Third, the cost of production is also divisible and can be calculated for each unit of the good (which is not to say that such calculation can be easily or accurately carried out). Goods such as bread and butter, shoes and ships and sealing wax, cabbages, and so on, are of this nature. There are also certain goods and services which do not have these characteristics. John Stuart Mill was actually the first to notice the fact that a good such as a lighthouse, once provided, confers benefits equally on all "consumers" (i.e. ships that navigate by it). Unlike the goods in the class above, the amount of service generated by a lighthouse does not diminish as more of it is "consumed." The total X available is actually what is available for each and every consumer, so that X =X =X = etc. Once available, the benefit is not confined to any one user: to make it available to one user is to make it available to other users. The overall benefit is not divisible among consumers. Finally, it is often meaningless to speak of units of the good, hence meaningless to speak of cost per unit. Costs are also not divisible. In this class of goods we can include, in addition to the lighthouse, national defense, clean air, pleasant surroundings, etc. In the economic literature of public finance, these goods are referred to as 2 collective goods (and those above, private goods). The nature of collective goods poses a number of problems. One is that it is difficult to extract payments from consumers, once the good has been provided. Since it is difficult, if not impossible, to exclude those who refuse to pay from consuming the good or service, it is unrealistic to expect any payments, or full payments. This being so, no private entrepreneur would be willing to produce collective goods. Generally, 41 they will not be provided unless there is some collective effort, hence the name collective goods. The second problem, as economists see it, is to work out the optimum level of production. This turns out to be theoretically simple, assuming that potential consumers truly reveal their... (shrink)

It is commonly supposed that people of Asia, particularly the ethnic Chinese, subscribe to values which are not conducive to economic progress. The gap between the capitalist West and Asia is often attributed to the 'cultural' factor. Behind such perception is the supposition that capitalism is wholly a product of the West, alien to Asia and cannot be successfully embraced without doing violence to its cultural traditions. Against this position, I argue that classical capitalism is perfectly compatible with the key (...) elements of Chinese philosophy. Whether or not there is anything in the suggestion of some historians that Quesnay borrowed from Confucianism, I argue that his economic doctrine could have developed from the fundamentals of Chinese philosophy. If I am right, the economic gap between the West and Asia has to be explained in terms other than the 'cultural' factor, such as, perhaps, colonialism and post-colonialist ideologies. (shrink)

Critical study of Yoga philosophy by with reference to Vedic literature, Indic philosophy and Yogasūtra of Patañjali.

Fodor's and Pylyshyn's stand on systematicity in thought and language has been debated and criticized. Van Gelder and Niklasson, among others, have argued that Fodor and Pylyshyn offer no precise definition of systematicity. However, our concern here is with a learning based formulation of that concept. In particular, Hadley has proposed that a network exhibits strong semantic systematicity when, as a result of training, it can assign appropriate meaning representations to novel sentences (both simple and embedded) which contain words (...) in syntactic positions they did not occupy during training. The experience of researchers indicates that strong systematicity in any form is difficult to achieve in connectionist systems.Herein we describe a network which displays strong semantic systematicity in response to Hebbian, connectionist training. During training, two-thirds of all nouns are presented only in a single syntactic position (either as grammatical subject or object). Yet, during testing, the network correctly interprets thousands of sentences containing those nouns in novel positions. In addition, the network generalizes to novel levels of embedding. Successful training requires a, corpus of about 1000 sentences, and network training is quite rapid. The architecture and learning algorithms are purely connectionist, but classical insights are discernible in one respect, viz, that complex semantic representations spatially contain their semantic constituents. However, in other important respects, the architecture is distinctly non-classical. (shrink)
