Wallace became a full-time naturalist in 1848, the year when he and Bates set out on their journey to South America. Wallace was twenty-five at the time and over half of his life had been spent in various parts of Wales, the land of his birth. Commentators have tended to gloss over or ignore any formative influences from this early period of his life or even to dismiss them as non-existent. This is surprising as it was during the eight or (...) so years in Wales leading up to 1848 that Wallace's interest in natural history emerged. ‘The importance of this early period in Wallace's life can scarcely be over-emphasized’ wrote Durant in his account of the development of the Wallace personality, but he omitted any specific reference to the significance of the early period in Wales. Those seeking a simple unitary cause for Wallace's conversion to natural history usually locate this in his visit to Leicester in 1844 and his meeting there with H. W. Bates. ‘The odyssey began … in 1844, in Leicester’ wrote Brooks, adding that ‘the more remote parts of … southern Wales had offered little reading material…’ This, and similar claims, are presumably founded primarily on Wallace's belief—expressed sixty years later—that it was at Leicester that he first familiarized himself with Malthus'Essay on the Principles of Populationand Humboldt'sPersonal Narrative of Travels in South America.There is, however, evidence that Wallace was probably familiar with at least one of these books some time before his visit to Leicester and that it was during his period in southern Wales that his interest in natural history emerged and developed.

Sustainable farming, and waysto achieve it, are important issues foragricultural policy. New Zealand provides aninteresting case for examining sustainableagriculture options because gene technologieshave not been commercially released and thereis a small but rapidly expanding organicsector. There is no strong governmentsubsidization of agriculture, so while policiesseem to favor both options to some degree,neither has been directly supported. Resultsfrom a survey of 656 farmers are used to revealthe intentions, environmental values, andfarming practices for organic, conventional,and GE intending farmers. The results show thatorganic (...) and conventional farmers are relativelysimilar but contrast to GE intending farmers,especially with respect to perceivedconsequences of each technology. While 75%of farmers have not yet made a commitmentto either technology, one fifth were GEintending and one quarter may become organic.Organic farmers have different attitudes tonature, matched in part by conventionalfarmers. In terms of policy for sustainableagriculture, the results suggest that organicand conventional farmers are incrementallymoving towards agroecological sustainabilitywhile GE intending farmers are committed tointensive production methods of which GEproducts are potentially important. GEintending farmers reject incrementalism infavor of a revolutionary technological fix forsustainability concerns in agriculture.Overall, the results show that there areclearly two different paradigms ofsustainability among farmers. Policies that areseeking to achieve sustainable agriculture needto address the tensions that span the differentparadigms. (shrink)

Focusing on a discussion by Ruddich and Stassen of the ?Remarks on Frazer's Golden Bough?, this paper shows that some of the usual criticisms made by sociologists of Wittgenstein are misplaced. He does not reject causal explanations of beliefs and actions and replace them with some other form of explanation, but dismisses the idea that any explanation is called for here. His argument that the origin of the desire to explain beliefs is to be found in a misconceived parallel between (...) science and magic is explained and discussed. (shrink)

The renaissance of pragmatism in recent decades has stimulated renewed study of the classical pragmatists. Until this volume, F. C. S. Schiller was the only major pragmatist from the classical era whose significant writings remained uncollected for renewed scholarly study. The forty-two pieces in this collection represent Schiller's finest writings. They range across a broad spectrum of specific topics: logic and scientific method, meaning and truth, pluralism and monism, personalism and idealism, metaphysics and values, evolution and religion, and ethics and (...) politics. An introduction to Schiller's life and career, introductory essays to the volume's seven parts, and a bibliography of Schiller's books and essays are also included. (shrink)

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.

We make three points: (1) Overlooked studies of nonhuman communication originally inspired, but no longer support, the blinkered view of mental continuity that Penn et al. critique. (2) Communicative discontinuities between animals and humans might be rooted in social-cognitive discontinuities, reflecting a common lacuna in Penn et al.'s relational reinterpretation mechanism. (3) However, relational reinterpretation need not be a qualitatively new representational process.

R.I.G. Hughes presents a series of eight philosophical essays on the theoretical practices of physics. The first two essays examine these practices as they appear in physicists' treatises (e.g. Newton's Principia and Opticks ) and journal articles (by Einstein, Bohm and Pines, Aharonov and Bohm). By treating these publications as texts, Hughes casts the philosopher of science in the role of critic. This premise guides the following 6 essays which deal with various concerns of philosophy of physics such (...) as laws, disunities, models and representation, computer simulation, explanation, and the discourse of physics.

W. E. Hocking has written recently that Whitehead's descriptive generalization of concrete fact, namely, his actual occasion, is “… not a term of description in the direct sense. It is an hypothesis. It cannot be kept in place by pointing to its presence as a datum: it can only hold its own if it proves to be a valuable conceptual tool.” I further advance the thesis that all generality is hypothetical, and holds it own only if it proves to be (...) conceptually useful. This is in accord with Whitehead's statement, the full implications of which have not been taken seriously enough, that metaphysical categories are not dogmatic statements of the obvious; they are tentative formulations of the ultimate generalities. But when these tentative formulations prove conceptually useful or are conceptually employed, they lose their “hypothetical air,” and often pass into what Whitehead calls a false state of “sober obviousness:”“An old established metaphysical system gains a false air of adequate precision from the fact that its words and phrases have passed into current literature. Thus propositions expressed in its language are more easily correlated to our flitting intuitions into metaphysical truth. When we trust these verbal statements and argue as though they adequately analysed meaning, we are led into difficulties which take the shape of negations of what in practice is presupposed. But when they are proposed as first principles they assume an unmerited air of sober obviousness.”. (shrink)

: Aristotle struggles with two basic tensions in his understanding of reality or substance that have parallels in Indian metaphysical speculation. The first of these tensions, between the understanding of reality as the underlying substrate (to hupokeimenon) and as the individual "this" (tode ti), finds a parallel in the concept of dravya in Patañjali's Mahābhāsa. The second tension, between the understanding of reality as the individual this and as the intelligible essence of the individual this (to ti ēn einai), corresponds (...) to an ambiguity in the concept of vastu in Kumārila's Ślokavārttika.

These original essays explore the philosophical implications of Newton's work.

The ontological argument, as understood by the first interpretation, runs as follows: The concept of God is the concept of a being than which nothing greater can be conceived. This latter concept includes the concept of a being which exists necessarily, for necessary existence is one of the perfections of an absolutely perfect being; that is, the concept of God is the concept of a being which exists necessarily. God then must conceived as existing necessarily, and hence we must attribute (...) to his essence necessary existence. According to the first interpretation, this inference from concepts alone constitutes the whole of the ontological argument. The argument is thus analytic and purely rational. (shrink)

Embryonic development combines paradoxical properties: it has great precision, it is usually conducted at breakneck speed and it is flexible on relatively short evolutionary time scales, particularly at early stages. While these features appear mutually exclusive, we consider how they may be reconciled by the properties of key early regulatory networks. We illustrate these ideas with the network that controls development of endoderm progenitors. We argue that this network enables precision because of its intrinsic stability, self propagation and dependence on (...) signalling. The network enables high developmental speed because it is rapidly established by maternal inputs at multiple points. In turn these properties confer flexibility on an evolutionary time scale because they can be initiated in many ways, while buffering essential progenitor cell populations against changes in their embryonic environment on both evolutionary and developmental time scales. Although stable, these networks must be capable of rapid dissolution as cell differentiation progresses. While we focus on the core early endodermal network of vertebrates, we argue that these properties are likely to be general in early embryonic stem cell populations, such as mammalian ES cells.

IntroductionResilience is a factor in how youth respond to adversity. The 88-item Adolescent Resilience Questionnaire is a comprehensive, multi-dimensional self-report measure of resilience developed with Australian youth.MethodsUsing a cross-sectional adolescent population, confirmatory factor analysis was conducted to replicate the original factor structure. Over half of the adolescents were non-white and 9th graders with a mean age of 15.5.ResultsOur exploratory factor analysis shortened the measure for which we conducted the psychometric analyses. The original factor structure was not replicated. The exploratory factor (...) analysis provided a 49-item measure. Internal consistency reliability for all 12 factors ranged from acceptable. The revised factor total scores were highly and significantly correlated with item–total correlation coefficients.ConclusionThis revised shorter 49-item version of the Adolescent Resilience Questionnaire could be deployed and has acceptable psychometric properties.

We begin by a summary of the standardized version of the model of the interaction between scientific activities and values (elaborated fully in Lacey and Mariconda, 2015), and based on it we argue that there is a profound incoherence in the self- understanding of the modern scientific tradition, and that the main options actually available to ensure continuity with the positive realizations of this tradition can be well represented by two sorts of ideal types that we name, respectively,“commercially orientated technoscience” (...) and “multi-strategic research”. Then, in the light of the predominance that commercially oriented technoscience has gained in contemporary scientific institutions, we argue for the importance of developing multi-strategic research in areas such as agriculture. This is needed so that adequate evaluation of the potential risks of large scale applications of technoscience, as well as harm they may have actually occasioned, can be made; and also so that these applications can be rigorously compared with scientifically informed practices, such as agroecology, which are not as problematic for human health and the environment and which explore the regenerative powers of nature itself.
