Observations of a sea urchin larvae show that most species adopt one of two life history strategies. One strategy is to make numerous small eggs, which develop into a larva with a required feeding period in the water column before metamorphosis. In contrast, the second strategy is to make fewer large eggs with a larva that does not feed, which reduces the time to metamorphosis and thus the time spent in the water column. The larvae associated with each strategy have (...) distinct morphologies and developmental processes that reflect their feeding requirements, so that those that feed exhibit indirect development with a complex larva, and those that do not feed form a morphologically simplified larva and exhibit direct development. Phylogenetic studies show that, in sea urchins, a feeding larva, the pluteus, is the ancestral form and the morphologically simplified direct‐developing larva is derived. The current hypothesis for evolution of the direct‐developing larval form in sea urchins suggests that major developmental changes occur by neutral loss of larval features after the crucial transition to a nonfeeding life history strategy. We present evidence from Clypeaster rosaceus, a sea urchin with a life history intermediate to the two strategies, which indicates that major developmental changes for accelerated development have been selected for in a larva that can still feed and maintains an outward, pluteus morphology. We suggest that transformation of larval form has resulted from strong selection on early initiation and acceleration of adult development. BioEssays 29:566–571, 2007. © 2007 Wiley Periodicals, Inc.

"Ist der Mensch in seinem Denken und Handeln ein geistig freies Wesen oder steht er unter dem Zwange einer rein naturgesetzlichen ehernen Notwendigkeit? Auf wenige Fragen ist so viel Scharfsinn gewendet worden als auf diese. Die Idee der Freiheit des menschlichen Willens hat warme Anhänger wie hartnäckige Gegner in reicher Zahl gefunden. Ein und dasselbe Ding wird hier gleich oft für das kostbarste Gut der Menschheit wie für die ärgste Illusion erklärt." Rudolf Steiner (Gröls-Klassiker - Edition Werke der Weltliteratur).

The Axiology of Theism The existential question about God asks whether God exists, but the axiology of theism addresses the question of what value-impact, if any, God’s existence does have on our world and its inhabitants. There are two prominent answers to the axiological question about God. Pro-theism is the view that God’s … Continue reading The Axiology of Theism →.

In this paper, I seek to contribute to post-phenomenological descriptions of human-technological relations and the intentionalities exhibited in them by focusingon the intentionality exhibited in the use of a cochlear implant. To do so, I will use concepts developed by Don Ihde and further extended by Peter-Paul Verbeek to show that while post-phenomenological categories illuminate the intentional relationship of a cochlear implant wearer to her world, this relationship defies easy categorization. An examination of successful functioning with a cochlear implant will (...) reveal a distinct form of technological embodiment and intentionality that confirms and extends previous post-phenomenological analyses.

APA PsycNET abstract: This is the first volume of a two-volume work on Probability and Induction. Because the writer holds that probability logic is identical with inductive logic, this work is devoted to philosophical problems concerning the nature of probability and inductive reasoning. The author rejects a statistical frequency basis for probability in favor of a logical relation between two statements or propositions. Probability "is the degree of confirmation of a hypothesis (or conclusion) on the basis of some given evidence (...) (or premises)." Furthermore, all principles and theorems of inductive logic are analytic, and the entire system is to be constructed by means of symbolic logic and semantic methods. This means that the author confines himself to the formalistic procedures of word and symbol systems. The resulting sentence or language structures are presumed to separate off logic from all subjectivist or psychological elements. Despite the abstractionism, the claim is made that if an inductive probability system of logic can be constructed it will have its practical application in mathematical statistics, and in various sciences. 16-page bibliography.

In my comments, I address two issues that are important but not central to the paper under review here. First, I present a reading of the postphenomenological concept of multistability by going back to Merleau-Ponty’s notion of the primacy of perception. I conclude that assertions affirming the multistability of technologies should not be seen as merely empirical. Second, I address the adequacy of using the language of ‘empirical’ and ‘transcendental’ as a means to categorize exclusionary approaches in philosophy of technology.

BackgroundIn December 2014, China announced that only voluntarily donated organs from citizens would be used for transplantation after January 1, 2015. Many medical professionals worldwide believe that China has stopped using organs from death-row prisoners.DiscussionIn the present article, we briefly review the historical development of organ procurement from death-row prisoners in China and comprehensively analyze the social-political background and the legal basis of the announcement. The announcement was not accompanied by any change in organ sourcing legislations or regulations. As a (...) fact, the use of prisoner organs remains legal in China. Even after January 2015, key Chinese transplant officials have repeatedly stated that death-row prisoners have the same right as regular citizens to “voluntarily donate” organs. This perpetuates an unethical organ procurement system in ongoing violation of international standards.ConclusionsOrgan sourcing from death-row prisoners has not stopped in China. The 2014 announcement refers to the intention to stop the use of organs illegally harvested without the consent of the prisoners. Prisoner organs procured with “consent” are now simply labelled as “voluntarily donations from citizens”. The semantic switch may whitewash sourcing from both death-row prisoners and prisoners of conscience. China can gain credibility only by enacting new legislation prohibiting use of prisoner organs and by making its organ sourcing system open to international inspections. Until international ethical standards are transparently met, sanctions should remain. (shrink)

Among the entities that can be mentally or linguistically represented are mental and linguistic representations themselves. That is, we can think and talk about speech and thought. This phenomenon is known as metarepresentation. An example is "Authors believe that people read books." -/- In this book François Recanati discusses the structure of metarepresentation from a variety of perspectives. According to him, metarepresentations have a dual structure: their content includes the content of the object-representation (people reading books) as well as the (...) "meta" part (the authors' belief). Rejecting the view that the object representation is mentioned rather than used, Recanati claims that since metarepresentations carry the content of the object representation, they must be about whatever the object representation is about. Metarepresentations are fundamentally transparent because they work by simulating the representation they are about. -/- Topics covered in this wide-ranging work include the analysis of belief reports and talk about fiction, world shifting, opacity and substitutivity, quotation, the relation between direct and indirect discourse, context shifting, semantic pretense, and deference in language and thought.

Since its publication fifty years ago, this work has established itself as a classic. It casts the visual process in psychological terms and describes the creative way one's eye organizes visual material according to specific psychological premises. In 1974 this book was revised and expanded, and since then it has continued to burnish Rudolf Arnheim's reputation as a groundbreaking theoretician in the fields of art and psychology.

This work provides a text and an extended study of those fragments of Heraclitus' philosophical utterances whose subject is the world as a whole rather than man and his part in it. Professor Kirk discusses fully the fragments which he finds genuine and treats in passing others that were generally accepted as genuine but here considered paraphrased or spurious. In securing his text, Professor Kirk has taken into account all the ancient testimonies, and in his critical work he (...) attached particular importance to the context in which each fragment is set. To each he gives a selective apparatus, a literal translation and and an extended commentary in which problems of textual and philosophical criticism are discussed. Ancient accounts of Heraclitus were inadequate and misleading, and as Kirk wrote, understanding was often hindered by excessive dogmatism and a selective use of the fragments. Professor Kirk's method is critical and objective, and his 1954 work marks a significant advance in the study of Presocratic thought. (shrink)

Two chief problems of the theory of knowledge are the question of meaning and the question of verification. The first question asks under what conditions a sentence has meaning, in the sense of cognitive, factual meaning. The second one asks how we get to know something, how we can find out whether a given sentence is true or false. The second question presupposes the first one. Obviously we must understand a sentence, i.e. we must know its meaning, before we can (...) try to find out whether it is true or not. But, from the point of view of empiricism, there is a still closer connection between the two problems. In a certain sense, there is only one answer to the two questions. If we knew what it would be for a given sentence to be found true then we would know what its meaning is. And if for two sentences the conditions under which we would have to take them as true are the same, then they have the same meaning. Thus the meaning of a sentence is in a certain sense identical with the way we determine its truth or falsehood; and a sentence has meaning only if such a determination is possible. (shrink)

History is composed of a web of innumerable interacting causal chains, many of which are composed of millions of discrete events. The complexity of history puts us in a position of having knowledge of only a minuscule portion of the consequences of any event, actual or proposed. Our almost complete lack of knowledge of the data necessary to know if an event is gratuitous makes it very likely that we would be mistaken about a very large number of events. The (...) complexity of history, therefore, poses a significant challenge to certain types of evidential arguments from evil that begin with our observations of evils that appear to be gratuitous.

This article breaks fresh ground on the probabilistic problem of evil, contesting its first premise (probably, if God exists, gratuitous evil does not exist) instead of the commonly contested second premise (probably, gratuitous evil exists). In so doing, it presents a rehabilitated version of Leibniz’s argument for the irrelevance of gratuitous evil vis-à-vis the existence of God, according to which it is logically impossible for any world God might create to be devoid of pointless evil. Accordingly, my argument provides theists (...) a more fruitful strategy for dealing with evil than asking skeptics to deny their intuitive recognition of pointless suffering. (shrink)

In this paper, I pursue a postphenomenological analysis of navigating with GPS in an automobile. I argue that GPS use is essentially different from navigating with a map insofar as one need not establish nor maintain orientation and directionality. Also, GPS provides a disembodied, omniscient navigational perspective. These aspects stem from the fact that GPS relies on earth-orbiting satellites, thereby reinforcing the modern view of the space/place relation that privileges abstract space over concrete, lived places. Following a postphenomenological thesis that (...) technologies are non-neutral mediators of human experience, I examine some important qualitative aspects of traveling with GPS. (shrink)

The topic of the sublime is making a return to contemporary discourse on aesthetics and cognition. In Sublime Understanding, Kirk Pillow makes sublimity the center of an alternative conception of aesthetic response and interpretation. He draws an aesthetics of sublimity from Kant's Critique of Judgment, bolsters it with help from Hegel, and establishes its place in a broadened conception of human understanding. He argues that sublime reflection provides a model for an interpretive response to the uncanny Other outside our (...) conceptual grasp; it advances our sense-making pursuits but eschews unified, conceptual determination. Thus "sublime understanding" is the always partial, indeterminate grasping of contextual wholes through which we make sense of the uncanny particular in both art and the lived world.The book is divided into three parts. In the first two parts, Pillow presents insightful reinterpretations of Kant's and Hegel's aesthetics. In the third part he develops his own model of an aestheticized understanding, which illuminates contemporary discussions of metaphor and interpretation, while bridging Anglo-American and continental treatments of these issues. The presentation is a model of clear and well-crafted exposition, exemplifying the practice of aesthetically reflective sublime understanding that it articulates. (shrink)

Available for the first time in 20 years, here are two important works from the 1920s by the best-known representative of the Vienna Circle.

Several philosophers and theologians have attempted to formulate monergistic, soft libertarian accounts of salvation. These accounts hold that the sinner has the ability to either resist or to do nothing at all with God’s universally given saving grace, in which latter case God will save her. However, I wonder with Cyr and Flummer whether these accounts go far enough because the nonresistant sinner voluntarily remains quiescent and is therefore arguably praiseworthy. I aim to remedy this alleged weakness by formulating a (...) possible account on which it never crosses the nonresistant sinner’s mind to resist, making her quiescence an involuntary omission. For all sinners whose minds it crosses to resist, they, on the proposed account, freely choose to resist. Combining Molinism with the scriptural notion of blaspheming against the Holy Spirit, I proceed to explain why it may cross the mind of some sinners and not others to resist. (shrink)

Rudolf Arnheim has been known, since the publication of his groundbreaking _Art and Visual Perception_ in 1974, as an authority on the psychological interpretation of the visual arts. Two anniversary volumes celebrate the landmark anniversaries of his works in 2009. In _The Power of the Center_, Arnheim uses a wealth of examples to consider the factors that determine the overall organization of visual form in works of painting, sculpture, and architecture. _The Dynamics of Architectural Form_ explores the unexpected perceptual (...) consequences of architecture with Arnheim's customary clarity and precision.

The journey of the Wycliffe Global Alliance is an example of how some paradigm shifts are influencing leading in mission. Since Christianity is both an agent and product of globalization, its beliefs have spread from one source to another, crossing religious, linguistic and cultural contexts. As a result, there are polycentric or multiple centres of influence since Christianity has homes within a diversity of contexts. This carries with it various implications including how partnering in mission needs to be deconceptualized through (...) greater emphasis on friendship. In order for this to happen as a missiological principle, third spaces may need to be created. Viewed against the backdrop of church and mission agency leadership, structures may be ‘stuck in the Industrial Era’. Therefore, the stage is set for exploring how these and other themes influence leadership in God’s mission. (shrink)

The question of whether or not to partition data for the purposes of inferring phylogenetic hypotheses remains controversial. Opinions have been especially divided since Kluge's (1989, Systematic Zoology 38, 7–25) claim that data partitioning violates the requirement of total evidence (RTE). Unfortunately, advocacy for or against the RTE has not been based on accurate portrayals of the requirement. The RTE is a basic maxim for non-deductive inference, stipulating that evidence must be considered if it has relevance to an inference. Evidence (...) is relevant if it has a positive or negative effect on a given conclusion. In the case of ℈partitioned’ phylogenetic inferences, the RTE is violated, and the basis for rational belief in any conclusion is compromised, unless it is shown that the partitions are evidentially irrelevant to one another. The goal of phylogenetic systematics is to hypothesize past causal conditions to account for observed shared similarities among two or more species. Such inferences are non-deductive, necessitating consideration of the RTE. Some phylogeneticists claim the parsimony criterion as justification for the RTE. There is no relation between the two – parsimony is a relation between a hypothesis and causal question(s). Parsimony does not dictate the content of premises prior to an inference. ℈Taxonomic congruence,’ ℈supertrees,’ and ℈conditional combination’ methods violate the RTE. Taxonomic congruence and supertree methods also fail to achieve the intended goal of phylogenetic inference, such that ℈consensus trees’ and ℈supertrees’ lack an empirical basis. ℈Conditional combination’ is problematic because hypotheses derived from partitioned data cannot be compared – a causal hypothesis inferred to account for a set of effects only has relevance to those effects, not any comparative relevance to other causal hypotheses. A similar problem arises in the comparisons of hypotheses derived from different causal theories. (shrink)

Egoicism, a mindset that places primary focus upon oneself, appears to be rampant in contemporary Western cultures as commercial advertisements, popular books, song lyrics, and mobile software applications consistently promote self-interest. Although a focus on oneself has adaptive value for physical preservation, decision making, and planning, researchers have begun to address the psychological, interpersonal, and broader societal costs of excessive egoicism. In an increasingly crowded and interdependent world, there is a pressing need for investigation of alternatives to a.

In the fall of 1957 the University of California Press expanded Arnheim’s 1933 book _Film_ by four essays and brought that landmark work back into print as _Film as Art._ Now nearly fifty years after that re-edition, the book continues to occupy an important place in the literature of film. Arnheim’s method, provocative in this age of technological wizardry, was to focus on the way art in film was derived from that medium’s early limitations: no sound, no color, no three-dimensional (...) depth.
