This collection of papers on issues in the theory of mental representation expresses a diversity of recent reflections on the idea that C. D. Broad so aptly characterized in the title of his book Mind and the World Order. An important impetus in the project of organizing this work were the discussions I had with Keith Lehrer while I was a Visiting Scholar in the department of Philosophy at the University of Arizona. His encouragement and friendship were of great value to me and I wish to express my thanks to him here. A word of thanks too for Mike Harnish who casually suggested the title...

A few years ago, a real break-through happened in observational astronomy: the un- derstanding of the effect of atmospheric turbulence on the structure of stellar images, and of ways to overcome this dramatic degradation. This opened a route to diffraction-limited observations with large telescopes in the optical domain. Soon, the first applications of this new technique led to some outstanding astrophysical results, both at visible and infrared wavelengths. Yet, the potential of interferometric observations is not fully foreseeable as the first long-baseline arrays of large optical...

The subtitle of this book should be read as a qualification as much as an elaboration of the title. If the goal were completeness, then this book would have included essays on the work of other philosophers such as Wilfrid Sellars, Nicholas Rescher, Donald Davidson, Gilbert Harman and Michael Williams. Although it would be incorrect to say that each of these writers has set forth a version of the coherence theory of justification and knowledge, it is clear that their work is directly relevant, and reaction to it could easily fill a companion volume. This book concentrates, however, on the...

Methods of reasoning lying at the heart of rational scientific inference are explored and applied in some 55 papers by contributors from industry, defense establishments, and academia, brought together under the sponsorship of the US Navy and several European and American chemical corporations. The

Thi s book ari ses from The Fourth European Coll oqui urn on Theoret i ca 1 and Quant itat i ve Geography wh i ch was he 1 din Ve 1 dhoven, The Netherlands in September 1985. It contains a series of papers on spatial choice dynamics and dynamical spatial systems which were presented at the colloquium, together with a few other soll icited ones. The book is intended primarily as a state-of-the art review of mainly European research on these two fastly growing problem areas. As a consequence of this decision, the book contains a selection of papers that differs in terms of focus, level of...

It is generally agreed that food, clothing and shelter are the three basic material needs of all people. A simple test for the successfulness of any economic system may therefore be the extent to which it succeeds in providing the population with these commodities. One would conjecture that in the countries that are generally considered as highly developed there would be no problems at all with their availability. And although this conjecture is to a large extent, confirmed by the evidence, it is nevertheless surprising that in western economies with the high per capita incomes housing is...

Several individuals noted the potentially important civilian uses of atomic energy shortly after the bombings of Hiroshima and Nagasaki in 1945. That year J. Robert Oppenheimer told a national radio audience that "in the near future" it would be possible to generate profitable electric power from "controlled nuclear chain reaction units" (reactors). It was suggested that, after fIfteen to twenty-five years of development, mature nuclear technology could provide virtually inexhaustible, cheap energy given the abundance of nuclear fuel. Admiral Lewis Strauss, the Chairman of the Atomic Energy...

My interest in gathering together a collection of this sort was generated by a fortuitous combination of historical studies under Professor Keith Lehrer and studies in cognitive science under Professor R. Michael Harnish at the University of Arizona. Work on the volume began there while I was an instructor in the Department of Linguistics and was greatly encouraged by participants in the Faculty Seminar on Cognitive Science chaired by Professor Lance J. Rips. I wish to express my appreciation to all of these and to many other individuals with whom I discussed the possibility of contribution...

Woody plants provide many challenges to the tissue culturist. Although there are many excellent tissue culture books and manuals available, these are generally strongly biased towards herbacious crops. Consequently, they often do not pay sufficient attention to the problems that specifically apply to in vitro culture of tree species. Culture of the latter often poses problems which are either absent or of lesser significance when culturing herbacious species.
When trees in the field are used as explant source, the problems can be especially severe. For example, the...

Many contemporary philosophers are interested in the scotistic notion of haecceity or thisness' because it is relevant to important problems concerning identity and individuation, reference, modality, and propositional attitudes. Haecceity is the only book-length work devoted to this topic. The author develops a novel defense of Platonism, arguing, first, that abstracta - nonqualitative haecceities - are needed to explain concreta's being diverse at a time; and second, that unexemplified haecceities are then required to accommodate the full range of cases in which...
