La sostenibilidad ambiental está relacionada directamente con el ciclo del agua y las intervenciones del hombre sobre el mismo, tanto en su extracción, uso y eliminación. La conservación del suelo y la vegetación dependen invariablemente del impacto acumulado de este proceso. La perspectiva de un cambio climático mayor, con el subsecuente aumento de las temperaturas en el planeta, implica transformaciones radicales en el ciclo del agua, y por ende, en su disponibilidad y utilización. Para ello se hace imperioso mejorar radicalmente (...) el ahorro del agua, aumentando al mismo tiempo los sistemas de depuración y eficiencia en el regadío. La autora propone una seria de medidas en esta dirección. (shrink)

C. J. Temminck, director of the Rijksmuseum van Natuurlijke Historie and a renowned ornithologist, gained his contemporary's respect thanks to the description of many new species and to his detailed monographs on birds. He also published a small number of works on biogeography describing the fauna of the Dutch colonies in South East Asia and Japan. These works are remarkable for two reasons. First, in them Temminck accurately described the species composition of poorly explored regions, like the Sunda Islands and (...) Japan. Secondly, he formulated a new law on the geographical distribution of animals around the globe, based on the parallels he observed between the fauna from Europe, Asia and Japan. The underlying ideas that lead Temminck to this law were the typeconcept, which he understood as the ideal morphological plan behind animal form, the unchanging character of the species and a strong belief in nature's divine design. During the first half of the nineteenth century, the type-and the species-concept, the origin and fixity of the species and the meaning of variations aroused heated discussions. When put in the context of his time, Temminck emerges as a scientist whose work was driven by the dominating scientific philosophy of the time in which he lived, under the influence of late eighteenth century natural history and of French empiricists, in particular, the great zoologist and paleontologist Georges Cuvier. Temminck's detailed descriptions of the Dutch East Indian fauna helped the great naturalists after him to understand nature's patterns and to propose comprehensive theories that explain its diversity.

By following the arguments between Coenraad J. Temminck and fellow ornithologists Louis J.-P. Vieillot and Nicholas Vigors, this paper sketches, to a degree, the state of zoological classification and nomenclature between 1825 and 1840 in Europe. The discussions revolved around the problems caused by an unstable nomenclature, the different definitions of genera and species and the best method to achieve a natural system of classification. As more and more naturalists concerned with classifying and arranging the groups of birds joined these (...) discussions, a broad platform for debate emerged around the 1840s that gave a major impulse to the disciplines of taxonomy and systematics. Natural history ceased to be dominated by a few influential scientific authorities and became the scientific field where debate preceded agreement and, with it, progress. With this ‘democratization’ of natural history, Temminck's status significantly changed between 1815 and 1840. After that year, his own views on classification along with certain economical and political developments in The Netherlands led Temminck to abandon the arena of ornithology and therefore, to lose his scientific authority.

A beautiful celebration of your child's uniqueness among all of God's creation, this colorful picture book by Cleere Cherry Reaves speaks the words on your heart about what a God-given miracle your little one will always be.

The problem of perception is the problem of explaining how perceptual knowledge is possible. The skeptic has a simple solution: it is not possible. I analyze the weaknesses of one type of skeptical reasoning by making explicit a dynamic epistemic principle from dynamic epistemic logic that is implicitly used in debating the problem, with the aim of offering a novel diagnosis to this skeptical argument. I argue that prominent modest foundationalist responses to perceptual skepticism can be understood as rejecting the (...) dynamic assumption made by the skeptic, that there are independent reasons to doubt the truth of such a principle in the context of skeptical reasoning, and that making the dynamic principle explicit allows for a better understanding of at least one objection to modest foundationalism.

Suppose that one is presented with a report of a miracle as an exception to nature's usual course. Should one believe the report and so come to favour the idea that a god has acted miraculously? Hume argued that no reasonable person should do anything of the kind. Many religiously sceptical philosophers agree with him, and have both defended and developed his reasoning. Some theologians concur or offer other reasons why those who are believers in God should also refuse to (...) accept accounts of miracles as accurate reportage. This book argues to the contrary. For Houston, miracle stories may contribute towards the reasonableness of belief in God, and, appropriately attested, may be accepted by believers in God. To bolster his case he examines historically and intellectually significant writings about the miraculous. And having argued for the rejection of Hume, he explores the implications of this rejection for science, history and theology. (shrink)

There are many who believe Moses parted the Red Sea and Jesus came back from the dead. Others are certain that exorcisms occur, ghosts haunt attics, and the blessed can cure the terminally ill. Though miracles are immensely improbable, people have embraced them for millennia, seeing in them proof of a supernatural world that resists scientific explanation. -/- Helping us to think more critically about our belief in the improbable, The Miracle Myth casts a skeptical eye on attempts to justify (...) belief in the supernatural, laying bare the fallacies that such attempts commit. Through arguments and accessible analysis, Larry Shapiro sharpens our critical faculties so we become less susceptible to tales of myths and miracles and learn how, ultimately, to evaluate claims regarding vastly improbable events on our own. Shapiro acknowledges that belief in miracles could be harmless, but cautions against allowing such beliefs to guide how we live our lives. His investigation reminds us of the importance of evidence and rational thinking as we explore the unknown. (shrink)

Sometimes, after years of painstaking work, someone presents a startling argument that seems to suddenly snatch the ground right out from under your feet. And it's back to square one. Such a conceptual trapdoor caught me by surprise a few years ago. For decades, I had been convinced it is simply inconceivable that subjectivity -- the interior experience of how consciousness feels -- could possibly emerge from a previously wholly objective world, that mind could evolve from ‘dead’ matter. It seemed (...) to me that the arguments of materialist philosophers, cognitive scientists and neuroscientists invariably missed the point. They always began with an assumption of ontological objectivity or physicality, and proceeded to show that that must be the source of consciousness. Well, of course, it had to be -- given their starting assumption. But what they were talking about wasn't consciousness at all. It was usually either some neural correlation, some computer analogue, or some complex and abstract linguistic deconstruction. Whatever their approach, the first-person experience of consciousness -- it's subjective feel -- always slipped through their grasp. They were looking at the problem from the third-person perspective -- from objectivity. And you can't get to here from there. (shrink)

The writing of yet another paper on miracles probably stands in need of justification. The justification I wish to claim has two aspects. Firstly, I think that the concepts of the miraculous usually defended and, in turn, criticized, are unacceptable and that a better one is available. Secondly, and more importantly, I think that these unacceptable concepts produce in virtue of their inherent weaknesses a situation in which only the less important questions get asked about miracles. These questions are those (...) which relate to the ontological status of miracles. I think it can be shown that is is the epistemological questions about miracles which are more interesting and important and, furthermore, that the standard accounts are so hemmed in by the difficulties raised for them that a preoccupation with ontological questions characterizes most discussion.

This short article aims to strengthen Hume's case against the rationality of believing in religious miracles by incorporating certain lessons borrowed from the growing literature on the history and psychology of magic tricks.

The concept of approximate truth plays a prominent role in most versions of scientific realism. However, adequately conceptualizing ?approximate truth? has proved challenging. This article argues that the goal of articulating the concept of approximate truth can be advanced by first investigating the processes by which science accords theories the status of accepted or rejected. Accordingly, this article uses a path diagram model as a visual heuristic for the purpose of showing the processes in science that are involved in determining (...) a theory's status. This ?inductive realist? model of theory status then serves as a starting point for explicating an inductive realist view of approximate truth that, it is argued, can explain instances of the success of science, but does not (1) require science's theories to be strictly true in any world or (2) require a metric for measuring how close an approximately true theory is to some strictly true theory. To show the advantages of the inductive realist approach to approximate truth, an example of a major success story of science, the successful eradication of smallpox, is reviewed and then explained.

Debates about the metaphysical compatibility between miracles and natural laws often appear to prejudge the issue by either adopting or rejecting a strong physicalist thesis (the idea that the physical is all that exists). The operative component of physicalism is a causal closure principle: that every caused event is a physically caused event. If physicalism and this strong causal closure principle are accepted, then supernatural interventions are rules out ’tout court’, while rejecting physicalism gives miracles metaphysical carte blanche. This paper (...) argues for a more moderate version of physicalism that respects important physicalist intuitions about causal closure while allowing for miracles’ logical possibility. A recent proposal for a specific mechanism for the production of miracles (Larmer 1996d) is criticized and rejected. In its place, two separate mechanisms (suitable for deterministic and indeterministic worlds, respectively) are proposed that do conform to a more moderate. (shrink)

Some have tried to make miracles compatible with the laws of nature by re-defining them as something other than interventions. By contrast, this article argues that although miracles are divine interventions, they are not violations of the laws of nature. Miracles are also not exceptions to the laws, nor do the laws not apply to them. The laws never have exceptions; they never are violated or suspended, are probably necessary and unchangeable, and apply also to divine interventions. We need to (...) reconsider not miracles but laws. The main claim of this article is that laws of nature do not entail regularities, and therefore that miracles do not violate the laws. We need a new theory of the laws of nature: the tendency theory. (shrink)

We approach the physics of \emph{minimal coupling} in general relativity, demonstrating that in certain circumstances this leads to violations of the \emph{strong equivalence principle}, which states that, in general relativity, the dynamical laws of special relativity can be recovered at a point. We then assess the consequences of this result for the \emph{dynamical perspective on relativity}, finding that potential difficulties presented by such apparent violations of the strong equivalence principle can be overcome. Next, we draw upon our discussion of the (...) dynamical perspective in order to make explicit two `miracles' in the foundations of relativity theory. We close by arguing that the above results afford us insights into the nature of special relativity, and its relation to general relativity. (shrink)

Miracles are not "violations" of nature. Contemporary miraculous healings seem to follow natural healing processes but to be enormously accelerated. Like grace, miracles elevate but do not contradict nature. Scriptural miracles, but also contemporary miracle accounts, have something to tell us about how God acts in the world.

This book explores three interrelated roots of scholarly work that have a supportive and elaborative affinity to authentic and engaging classroom inquiry: ecological consciousness, Buddhist epistemologies, philosophies and practices, and interpretive inquiry or «hermeneutics». Although these three roots originate outside of and extend far beyond most educational literature, understanding them can be of immense practical importance to the conduct of rich, rigorous, practicable, sustainable, and adventurous classroom work for students and teachers alike. The authors collectively bring to these reflections decades (...) of classroom experience in grades K-12 and the experience of supervising hundreds of student teachers in such settings as well as working regularly with schools and classroom teachers in their day-to-day work. The authors demonstrate, through several classroom examples, how ecology, Buddhism, and hermeneutics provide ways to re-invigorate the often-moribund discourse of education and bring a sense of beauty and rigorous joy to classroom life for teachers and students alike.

Joseph Houston’s book is a fine contribution to the philosophical investigation of the value of miracle reports for religious apologetics. It covers a wide range of arguments of interest to philosophers about the concept of miracles and the justifiability of belief in their occurrence, but it is also rich in theological and biblical sources. Houston’s reasoning throughout is careful and subtle, but neither technical nor excessively pedantic. So while the book is primarily intended for scholars, students should find it within (...) their reach. (shrink)

The claim that a miracle is a violation of a law of nature has sometimes been used as part of an a priori argument against the possibility of miracle, on the grounds that a violation is conceptually impossible. I criticize these accounts but also suggest that alternative accounts, when phrased in terms of laws of nature, fail to provide adequate conceptual space for miracles. It is not clear what a ???violation??? of a law of nature might be, but this is (...) not relevant to the question of miracles. In practice, accounts of miracle tend to be phrased in terms of God's act not in terms of laws of nature. Finally, I suggest that the a priori argument reflects an intellectual commitment that is widely held, though wrongly built into the argument itself. (shrink)

Construing miracles as \textquotedblleft{}violations,\textquotedblright I argue that a law of nature must specify some kind of possibility. But we must have here a sense of possibility for which the ancient rule of logic---ab esse ad posse valet consequentia---does not hold. We already have one example associated with the concept of statute law, a law which specifies what is legally possible but which is not destroyed by a violation. If laws of nature are construed as specifying some analogous sense of what (...) is naturally possible, then they need not be invalidated by a (rare) violation, and Humean miracles remain a genuine possibility.

In this paper, I draw out a tension between miracles, prophecy, and Spinoza’s assertions about Moses in the Theological-Political Treatise (TTP). The three seem to constitute an inconsistent triad. Spinoza’s account of miracles requires a naturalistic interpretation of all events. This categorical claim must therefore apply to prophecy; specifically, Moses’ hearing God’s voice in a manner which does not seem to invoke the imagination or natural phenomena. Thus, Spinoza seemingly cannot maintain both Moses’ exalted status and his account of miracles. (...) I consider some possible solutions, but find that they are either untrue to Spinoza’s position, or would undercut his categorical argument against miracles. I therefore conclude that Spinoza leaves an unresolved tension in the TTP. (shrink)
