M. Oaksford and N. Chater presented a Bayesian analysis of the Wason selection task in which they proposed that people choose cards in order to maximize expected information gain as measured by reduction in uncertainty in the Shannon-Weaver information theory sense. It is argued that the EIG measure is both psychologically implausible and normatively inadequate as a measure of epistemic utility. The article is also concerned with the descriptive account of findings in the selection task literature offered by Oaksford and (...) Chater. First, it is shown that their analysis data reported in the recent article of K. N. Kirby is unsound; second, an EIG analysis is presented of the experiments of P. Pollard and J. St. B. T. Evans that provides a strong empirical disconfirmation of the theory. (shrink)

Cognitive Development and Acquisition of Language.

Accepted quantum description is stochastic, yet history is nonstochastic, i.e., not representable by a probability distribution. Therefore ordinary quantum mechanics is unsuited to describe history. This is a limitation of the accepted quantum theory, rather than a failing of mechanics in general. To remove the limitation, it would be desirable to find a form of quantum mechanics that describes the future stochastically and the past nonstochastically. For this purpose it proves sufficient to introduce into quantum mechanics, by means of a (...) perfected formal correspondence, certain analogs of the classical initial-condition constants. Through the restoration of such parameters at the quantum level one accomplishes a natural accommodation of time anisotropy, wave-function reduction, and “event” description by quantum mechanical equations of motion alone, without the need for extra postulates (e.g., a projection postulate). This requires a complete restructuring of quantum measurement theory. (shrink)

"This is but an essay, incomplete, tentative--indeed, fumbling. I would ask for more attention to its outlook and technique or method than to its details, for the former come from me as a moral philosopher, which I am by profession, whereas the latter come from me as a moralist, which I am by conceit." -- From the Preface.

In poem 64 Catullus, as Fordyce points out in his edition , often has lines enclosed by a noun and its adjective, e.g.: 5 auratam optantes Colchis avertere pellem Very often, but not always, a syntactical unit is enclosed as well as the line. This is perhaps not surprising, considering the prevalence of punctuation at the end of the line in this poem. Nevertheless, an examination of the lines will show that when a noun and adjective1 enclose both line and (...) syntactical unit the fact that they enclose a syntactical unit can be regarded as a determinant of the word order.

In this second part of our paper abeta structure hypothesis is advanced, according to which all matter and the vacuum are composed solely of electrons. A direct connection is established between beta processes and nuclear forces. Physical implications of the formalism introduced in Part I are examined. Localized violation of the Heisenberg postulate opens extensive descriptive possibilities inaccessible to current field-derived theories. A weakness of the present attempt at “elementary” particle description is its incapacity to predict observed masses or spatial (...) extensions. This results from the particular (one-body) model employed, which posits an infinitely massive point “force center.” Improvements in the formulation of the relativistic many-body problem will be required to correct this shortcoming. In summary, our investigation reaffirms the logical sufficiency (surmised by Newton) of the elements of mechanics for describing the phenomena of nature. (shrink)

In preceding parts of this paper the possibility was examined of accomplishing the entirety of physical description by means of mechanics, without help from field-theoretical ideas. Apart from some easily obtained qualitative agreements with general descriptive features of nuclei and elementary particles, we were balked in this program by an inability to handle in purely mechanical terms the relativistic many-body problem. The present paper is addressed directly to the latter problem. No quantitative calculations are attempted, but three suggestions are made (...) — each of a quite radical nature — concerning the reformulation that will be necessary to restore mechanics to the mainstream of physics.

Commentary on Tarkasaṅgraha of Annambhaṭṭa, active 17th century, treatise on the fundamentals of Nyaya philosophy.

The following notes on the In Pisonem are largely based on the commentary of R. G. M. Nisbet . The references to the speech are by section and line of his text, and where my note is based on one of his I add a reference to the page of his commentary. 1. 20 voltus …, qui sermo quidam tacitus mentis est: ‘thoughts are usually revealed by the face.’ Add to Otto's, Seyffert-Muller's, and N.'s examples: Curtius 8. 6. 22 ‘voltus (...) haud sane securi animi index’, Juv. 9. 18 ff.
