R.I.G Hughes offers the first detailed and accessible analysis of the Hilbert-space models used in quantum theory and explains why they are so successful.

Locus equations offer promise for an understanding of at least some aspects of perceptual invariance in speech, but they were discovered almost fortuitously. With the present availability of powerful machine learning algorithms, ignorance -based automatic discovery procedures are starting to supplant knowledge-based scientific inquiry. Principles of self-learning and self-organization are powerful tools for speech research but remain somewhat under-utilized.

There has been a revival of interest in Hegel of late among English-speaking philosophers. Although he is still regarded as maddeningly obscure, a number of important philosophers have been attracted by a doctrine prominently associated with Hegel, the coherence theory of truth. In order to hold the coherence theory of truth, it is obvious that you must hold what might be called the coherence theory of truth-testing as well: for if this theory is wrong and we can test some statements (...) by, for example, introspection as well as in terms of coherence, truth must involve something more than just coherence. My arguments against the coherence theory of truth-testing, since it is implied by the coherence theory proper, are indirectly against the coherence theory as well. I also argue that unless some version of the Private Language Argument is successful, it is virtually impossible to defend the coherence theory of truth-testing without denying the existence of experiences, thereby committing oneself to materialism.

Molinism attempts to resolve the incompatibility of divine foreknowledge and human libertarian freedom by the inclusion of the divine will into the solution. Moreover, middle knowledge is providentially useful under the Molinist model because of the way God uses it. This speaks of an integral link between the divine will and intellect that works in such a way as to provide a foreknowledge solution and, allegedly, the best view of providence. Nevertheless, there have been several anti-Molinist arguments by analogy which (...) suggest that the God presented in the Molinist model is a manipulator, and therefore something is lost or undermined in the libertarian freedom that Molinism purports to uphold through its model of foreknowledge and providence. This thesis examines the anti-Molinist charge of manipulation primarily by analysing how God uses information known through middle knowledge. The findings of the anti-Molinist arguments from analogy are reconstructed to form deductive arguments. These are evaluated against standard definitions of objectionable manipulation. It is concluded through analysis of these stronger, deductive arguments that divine providence under the Molinist model is a case of objectionable manipulation, one which many theists, classical or progressive, should find abhorrent. The effects of manipulation on ostensible libertarian freedom are then analysed, leading to the conclusion that Molinist-style manipulation results in a form of free-will compatibilism, ergo, the divine foreknowledge problem is not answered, nor is the result compatible with libertarian freedom. Given that it is close to a form of divine determinism, Molinism is then compared with Calvinism along several lines of criticism, namely whether such a God is good, loving and personal. (shrink)

Universal human values-this is one of the most frequently encountered phrases today; we are constantly coming across it on the pages of newspapers and magazines. Its frequency creates the illusion that its content is intuitively clear, attractive, and shared by everyone. However, the various versions of what is understood by universal human values-the good, truth, beauty, freedom, or civil society, a non-nuclear world, ecological protection, pluralism, etc.-show that this is by no means the case.

John Searle attempts to show through a consideration of promising that at least some ‘ought’ statements can be derived from ‘is’ statements. He thinks that you can determine on purely factual grounds that a person has made a promise, and that it follows logically from the statement that a person has made a promise that he has at least a prima facie obligation to do the thing he promised to do. I agree with but not with.

I argue that, while Finlay et al, are correct to suggest that there are developmental regularities (or constraints) acting on brain component evolution, they are incorrect to infer from this that a developmental explanation necessarily implies that structural changes preceded functional use. Developmental and functional (adaptationist) explanations are complementary, not alternatives.

While the evidence that cetaceans exhibit behaviours that are every bit as cultural as those recognised in chimpanzees is unequivocal, I argue that it is unlikely that either taxon has the social cognitive mechanisms required to underpin the more advanced forms of culture characteristic of humans (namely those that depend on shared meaning).

Contributed articles on literary theory.

In 1962 appeared one of the classic articles in Anglo-Saxon manuscript studies, the publication of two eleventh-century fragments of leaves of Old English found in the binding of a seventeenth-century printed book in the library of the University of Kansas, Lawrence. The fragment that more nearly concerns the present article now carries the shelf mark Pryce MS C2:1 in the Kenneth Spencer Research Library . It is a large part of a single leaf from The Legend of the Holy Cross (...) before Christ, an edifying work known in full only in a twelfth-century copy, Oxford, Bodleian Library, MS Bodley 343, fols. 14v–20v . Working from a photograph the great paleographer and codicologist N. R. Ker attributed the hand of the Kansas fragment to the scribe who also wrote the texts of two bits of the same work found in the library of Matthew Parker, archbishop of Canterbury , at Corpus Christi College, Cambridge, now MS 557 . He concluded, no doubt rightly, that all three are part of one manuscript. (shrink)

During the second half of the XX century drug addiction ceased to be only the epiphenomenon of crime, prostitution and a number of other social-relations deviation, and became a constant value of post-industrial society and at the end of XX century turned into a global problem of mankind. A new form of mass neurosis shows that drug dependence is nowadays socially conditioned mental degeneration, caused by activation of unconscious collective archetypes that are experienced depending on the corresponding situation. The identification (...) of the sacred plant soma/haoma with the marihuana enables us to not only to make clear the light and the dark sides of this archetype, but also to figure out that the reduction of the drug addiction problem, to the acceptable for the society level, is possible only if a man will be able to satisfy his “life-asserting, vital needs”, if he will be able to regain the true meaning of life.

I try to show that there is much sap (synthetic a priori) knowledge although one may not find many, or even any, sap true statements in most natural languages. Reasons are given for the difficulty of expressing sap truths in natural languages, but it is argued that these are not necessary features of language as such. There are, then, sap true statements in some possible languages.Admission of the sap gives one a way of distinguishing logical from metaphysical possiblity. Something is (...) metaphysically impossible just in case it is a sap truth that it is impossible. I argue that the realm of logically possible entities is vastly larger than the realm of metaphysically possible entities.My.defence of the sap begins with a partial defence of the analytic/synthetic distinction. In particular, I attack the intentionality circle argument,Quine's indeterminacy thesis and some applications of the Kripke/Putnam theory of meaning for natural kind terms. Without being a conclusive defence of the analytic/synthetic distinction, this section makes the defence of the sap more secure. Arguments are then mounted in direct defence of the sap by showing that the purported reduction of sap truths to analytic truths is mistaken. Examples are adduced to show that, even where expressions of natural language fail, one can stipulate usage in ways that allow expression of sap truths. I then consider and reply to various objections, giving an example of the sort of meaning theory which illegitimately legislates the analyticity of any purported sap true statement. (shrink)

In my target article, I argued (1) that the relationship between neocortical size and group size in primates implies that there is a cognitive limit on the size of human groups, and (2) that time constraints forced the evolution of language as a more efficient means of bonding the large groups that humans evolved. The doubts about these claims raised by these additional commentaries largely reflect misinterpretation of my original claims.

The present stage of development of the philosophy of language is marked by the joining of efforts of philosophers, logicians, and linguists for solution of one of the most difficult problems posed by the progress of scientific knowledge - the problem of modeling the aspect of meaning, of semantics, of natural language. The solution of this problem governs not only the building of a general theory of language, not only scientific explanation of the phenomenon of the understanding of language and (...) solution of numerous problems of practical importance with respect to automatic language processing, but also the defining of the place and function of language in the process of cognition and understanding of the world, a matter that is fundamental to methodology.
