The objective of this work is to categorize the available fly ashes in different parts of the world into distinct groups based on its compositional attributes. Kohonen's self-organizing feature map and radial basis function networks are applied in a cascading fashion for the classification of fly ashes in terms of its chemical parameters. The basic procedure of the methodology consists of three stages: apply self-organizing neural net to ascertain possible number of groups, delineate them and identify the group sensitive attributes; (...) find mean values of sensitive attributes of the elicited groups and augment them as start-up prototypes in k-means algorithm and find the refined centroids of these groups; incorporate the centroids in a two layer radial basis function network and fine-tune the delineated groups and develop an indexing equation using the weights of the stabilized network. Further, to demonstrate the utility of this classification scheme, the so formed groups were correlated with their performance in High Volume Fly Ash Concrete System [HVFAC]. The categorization was found to be excellent and compares well with Canadian Standard Association's [CSA A 3000] classification scheme. (shrink)

The author analyses the change in the Tamil Śaiva bhakti concept of corporeality showing that understanding the body of a bhakta as the main obstacle to connecting with the body of Śiva based on the attitude of rejecting one's corporeality has much in common with Buddhist and Jain ideas about the body. Therefore, the main task of the bhakta was to liberate from his body, its elimination or transformation (remelting the physical body as an impure body, as an obstacle body (...) on the way to union with God). They solved this task in various ways, including various practices of ecstatic behaviour and self-harm. The concept of kaya siddhi put forward by Tirumūlar is the idea of a perfect body, potentially immortal and homologous to the body of Śiva. He also formulated and developed sophisticated techniques for using the physical body of a sādhaka as the primary tool for achieving liberation based on yoga techniques and working with the mind of an adept. The result achieved was presented in the description of Tirumūlar's own mystical experience. As a result, he achieved the state of the super material body of yoga-deha, the ideal of which is the manifest body of Śiva as Naṭarāja. The new iconography of Naṭarāja formed in the visionary insights of bhaktas, who described their darśans in their hymns. Then it became the basis for forming a new iconology of Naṭarāja and the cult of images of the bhaktas themselves embodied in the intensive temple construction of the Chola Empire. In combination with new ritual practices, the Tamil philosophy of Śaivism had formed as a tripartite religious and philosophical canon of Śaiva Siddhānta. This canon included the poetic canon of Śaiva bhakti (Paṉṉiru Tirumuṟai), the agamic temple ritual, and 14 philosophical treatises of Śaiva Siddhānta (Meikaṇṭar Shastras). (shrink)

La admirable riqueza cultural y artística del Renacimiento esconde una desoladora miseria y aquella "edad de la abundancia" contrasta con una inmensa pobreza. Lejos de ser una broma o una pesadilla, la celebrada Utopía de Tomás Moro fue antes que nada un desafío insoslayable, pues proponía que ninguna sociedad merece tal nombre si tolera la miseria de un solo pobre. Rico y pobre explora la cuestión en ese libro de 1516 y en otros del escritor londinense para concluir con un (...) esbozo de su vida a la luz de la pobreza como virtud indispensable y libertadora. He aquí un hombre afortunado que no fue indiferente ante el infortunio de tantos y que vio en la humanitas la virtud por excelencia que lleva a una constante atención y cuidado del prójimo. Inspirado por un cambio de actitud en su época, así como por su fe cristiana y la mejor tradición estoica, mostró una robusta preocupación sobre el tema subrayando el valor social que debe tener toda riqueza, tanto a nivel estatal como individual, destacando la grave obligación cívica de los ricos y la necesidad que tienen todos, ricos y pobres, de empeñarse en la práctica de cierto desprendimiento y generosidad si no quieren mermar su propia humanidad y fallecer en su avaricia. La percepción de la miseria había cambiado de tal manera que su remedio ya no podía estar en una u otra limosna en plazas e iglesias, sino en la acción bien pensada y perentoria de todo gobierno que se tenga por justo. Sir Tomás Moro, privilegiado desde la cuna y seguro en su trabajo profesional, vio la pobreza de tantos como un desastre social, pero uno que, al mismo tiempo, debería llevar a todo ser humano a ver en el desprendimiento y generosidad una excelencia o virtud que alumbra la "otra" libertad, y tan íntima y valiosa que en su caso brilló aun en la prisión y ante el horror de una muerte injusta y atroz." -- Page 4 of cover.

In lieu of an abstract, here is a brief excerpt of the content:570 BOOK REVIEWS like reasonable rule for economic life. This effort is worthy of more attention than is possible here, but let it be noted that it must inevitably suffer the same fate as any ethical calculus: someone must decide for others what is their due and what is not. How much wealth, for example, makes for a concentration [of wealth] that would be " demonstrably detrimental to some (...) people's exercise of their generic rights "? His is ultimately an entitlement or rights ethic, rather than an aitial ethic of goal-purposive fulfillment for the individual, projected outwards for a common good scenario. While his rejection of goal ethics's inability to detail principles for distribution of goods is noteworthy, it does not appear that a tightened version of generic rights theory will come closer to either of Phillips's desiderata: a justification of moral reasoning apart from any theory of nature or a calculus for its application. Desan and Phillips wish to think against the limits of the human situation. For Desan, rising above limitation is a moral task and obligation facing us each, if there is to be a common future. His call is to be World Citizen in a Polis of Nations. Phillips's vision is more concrete, a distribution of benefits to benefit all with well-being and freedom. But this mundane task is no less difficult than Desan's transcendent one. Indeed, according to Augustine, even the Divine Mind must utilize an artifice in dealing with human creation: "He loves each of us as though there were only one of us." Both ethicists have striven to show us how we might think this vision for ourselves, i.e., for each other of us. ]OIIN B. DAVIS, O.P. ' Detroit, Michigan Catholics, Anglicans, and Puritans: Seventeenth-Century Essays. By HUGH TREVOR-ROPER. Chicago: The University of Chicago Press, 1988. Pp. xiii + 317. $27.50 (hardbound). Even to list the changes and events which occurred in seventeenth century England is a difficult task: the century spans the period from the death of Queen Elizabeth to the Glorious Revolution and beyond, through the Civil War, the accession and exile (twice) of the Stuarts, the rise of science, the transformation of the theological and religious issues of the English Reformation, to name only the most obvious. To conceive a book, in the form of occasional essays, which not only addresses these changes and events but does so by establishing the connections which were present with European currents at the same time surely tempts fate, even when it does not tempt reviewers. BOOK REVIEWS 571 But Hugh Trevor-Roper is a master, both of the period under survey and of the form of the essay. With one exception, each of these essays began as a lecture or seminar paper, and the pleasantly legible style in which they are written must bear some trace of that origin. The occasional flashes of wit, mixed with rthe fairly non-technical style, make the book a joy to read and a welcome escape from the usually constipated style of scholarly prose. In his Introduction, the essayist clearly sets forth his thesis that English intellectual history does not exist apart from the currents of European intellectual history (a thesis for which Trevor-Roper has already staked a claim). That leads to what may very well be the major problem with these essays: its end is in its beginning. The list of names cited in these essays only partially coincides with the list of names in the index; the former is much longer than the latter. And while the style of the essay welcomes the reader to the period, it also throws up more names and places and events than can be explained or even annotated adequately. This occurs both on a large and on a small scale. The first essay, on "Nicholas Hill, the English Atomist" contains such a vast array of names that at times it becomes the prosopo· graphical equivalent of a telephone book. On a large scale, there is the problem with a definition of Arminianism. No definition, at least no formal definition, is attempted-and this is probably wise. But, particularly in... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS The Inference That Makes Science. By ERNAN McMULLIN. The Aquinas Lecture, 1992. Milwaukee: Marquette University Press, 1992. Pp. iv +112. In this ambitious lecture Father Ernan McMullin recapitulates and refines a thesis that has guided his thought for the past forty years. In essence the thesis is this: precisely how science is made has eluded the best minds for centuries, and only in the work of Charles (...) Sanders Peirce, suitably emended by McMullin, has the puzzle finally been solved. " Retroduction " is the inference that makes science. Once this is understood, errors on what constitutes scientific method-those of Aristotle, Aquinas, Galileo, Newton, Bacon, Hume, et al.-can be rectified and one can see science for what it truly is: a complex process of theory appraisal that yields, not definitive truth, but well-established results to which assent can be given with at best "practical certainty," whatever that might be (pp. 91-96). Why McMullin should have chosen such a theme for an Aquinas Lecture is a question that defies reasonable answer. Surely one does not have to he so negative about the thought of Aristotle, Aquinas, and Galileo to advance one's ideas about science in the present day. What McMullin could easily have done, and he hints at this in the last two paragraphs of his lecture (pp. 97-98), is show how retroduction is itself simply a relaxed version of the demonstrative regress, the method actually endorsed by Aristotle, Aquinas, and Galileo. Such a retroductive version, fair enough, yields knowledge of a probable cause, the type of knowledge most typical of modern science. McMullin did not have to embark on the dangerous course of trying to prove that proof and certainty are forever beyond the grasp of science, or that never in the history of science has anyone established a definitive truth. That, in effect, is what McMullin has tried to do, and in the attempt to make the point he fumbles at almost every juncture throughout a very long lecture. To set the record straight more than a review is being re--·quested; perhaps a book, and even that might not suffice for those whose minds are made up. To understand the import of the lecture one must appreciate that it is hut a brief episode in a debate over demonstration in science that has been going on since McMullin first came to the University of Notre Dame in 1954. I myself have published many hooks and articles that engage the very point of his lecture and provide the contra evidence to 131 132 BOOK REVIEWS show elements of continuity in scientific method from Aristotle to the present. My last two volumes, in press at the same time as McMullin's Aquinas Lecture, answer in detail the aporiai he there raises.1 I need 1 Galileo's Logic of Discovery and Proof.

Some idea of the flavor of our debate, however, can be gained from the following. To support his thesis, McMullin has to maintain that Aristotle's proof that the moon is a sphere (from its having phases) and that Galileo's proofs that there are mountains on the moon, that Jupiter has satellites, and that Venus circles the sun (all based on telescopic observations) are not strictly demonstrative, that is, they do not yield true and certain conclusions. He declines to answer a query I have often tendered whether he personally is certain on the basis of pre-spacecraft evidence that the moon is a sphere, that there are mountains on it, that Jupiter has satellites, and so on. Instead he offers the categorical response "that planetary science is not an apodictic science, indeed that no natural science is... (shrink)

The East has seen totality in a far more consistent and systematic way than the West; and India more so than any other civilisation in the East. When the Swami Siddheswarananda came to France to lecture on Vedic philosophy, he entitled his address, Outline of a Philosophy of Totality’. The expression could have been applied to the philosophies of India as a whole. But the world of thought, coextensive with culture, is far broader than philosophy. It is no exaggeration to (...) assert that India is the land of totality par excellence. Is it not even, according to one dictum, bigger than the world …? The notion of totality, implicit or conscious, poetic or theoretical, original or final, is present throughout Indian culture, both in its religion and in its arts, both in its customs as in its language. The Mahabharata, the largest epic poem ever conceived, proclaims: everything in the Mahabharata can be found elsewhere, but what is not in the Mahabharata cannot be found anywhere. Whilst the absolute beginning of a piece of Western music is in keeping with a dramatic time analogous to that of the Creation, Indian music seems to come from the eternity of a universe without transcendence. The body takes on a cosmic meaning through dance. By performing the tandava, the cosmic dance, Shiva Nataraja (‘Lord of the dance’) endlessly creates and destroys worlds. Indian art is an art of proliferation: both the reiteration of motifs sculpted in architecture and the litanies and metaphors spun out in epic poetry are symbolic attempts to capture the totality of the world. Every single element, being, movement or thing within this continuous space and time points towards all the others. The texts describe the sky of Indra with its web of pearls arranged in such a way that when one looks into one, one sees all the others reflecting in it; in the same way, each object of this world is not merely itself but comprises every one of the others and actually is all the others. The culture of India is one of plenitude, presence and continuity. At the opposite extreme, Japan developed a culture based upon the values of emptiness, absence and the interval. When a guru speaks, Valmiki and Vyasa know that it will take them many scores of verses. A Zen master's reply to his disciple takes up a single-line anecdote, or a word, or even a silence. At the other extreme, hundreds of statues line the gopuram of the temple at Madurai: not all of the thirty-three million gods ‘recognized’ in the writings are there, of course, but at least their unbelievable abundance gives us a plausible image of them.
