Since its introduction, multivariate pattern analysis, or ‘neural decoding’, has transformed the field of cognitive neuroscience. Underlying its influence is a crucial inference, which we call the decoder’s dictum: if information can be decoded from patterns of neural activity, then this provides strong evidence about what information those patterns represent. Although the dictum is a widely held and well-motivated principle in decoding research, it has received scant philosophical attention. We critically evaluate the dictum, arguing that it is false: decodability (...) is a poor guide for revealing the content of neural representations. However, we also suggest how the dictum can be improved on, in order to better justify inferences about neural representation using MVPA. 1Introduction 2A Brief Primer on Neural Decoding: Methods, Application, and Interpretation 2.1What is multivariate pattern analysis? 2.2The informational benefits of multivariate pattern analysis 3Why the Decoder’s Dictum Is False 3.1We don’t know what information is decoded 3.2The theoretical basis for the dictum 3.3Undermining the theoretical basis 4Objections and Replies 4.1Does anyone really believe the dictum? 4.2Good decoding is not enough 4.3Predicting behaviour is not enough 5Moving beyond the Dictum 6Conclusion.

The paper addresses the formation of striking patterns within originally near-homogenous tissue, the process prototypical for embryology, and represented in particularly purist form by cut sections of hydra regenerating, by internal reorganisation of the pre-existing tissue, a complete animal with head and foot. The essential requirements are autocatalytic, self-enhancing activation, combined with inhibitory or depletion effects of wider range – “lateral inhibition”. Not only de-novo-pattern formation, but also well known, striking features of developmental regulation such as induction, inhibition, and (...) proportion regulation can be explained on this basis. The theory provides a mathematical recipe for the construction of molecular models with criteria for the necessary non-linear interactions. It has since been widely applied to different developmental processes. (shrink)

There are, I think, three distinct senses in which Rousseau uses the term “general will.” He means by it, as the nineteenth century Idealists used to point out, something very like Kant's “good will,” which all men have in common and which cannot conflict with itself. But he also means, quite as often, the Utilitarian compromise, The mean between divergent interests which takes account of all of them and satisfies as many as possible. And, thirdly, he means something like the (...) “culture pattern” of the modern anthropologists. I want to show that Green inherits this ambiguity, and that his argument in the Principles of Political Obligation is plausible only because he does not distinguish between these three meanings of “general will.”.

The method and criteria that are used for detecting the aesthetic value in works of art are among the key themes of aesthetic epistemology. The object of this study is to attempt a rational reconstruction of the background of art criticism. In tradition Western thought, aesthetic value lies in archieving unity in complexity, unitas multiplex. In the 20th century, this duality was enriched by a third category, intensity. In 1989, Tomáš Kulka suggested that these three categorical features could be detected (...) within works of art by applying a falsification proving method to the aesthetic value. Kulka described an intuitive process of assessing the aesthetic value of works of art by finding possible alternations that would contribute to improving and/or damaging the work of art. The number of possibilities thus found may lead us to recognize the aesthetic value of the work of art. This paper addresses Kulka's concept, emphasizing some of its potential problematic aspects and concluding with a suggested percentage modification of Kulka's concept that might better correspond with an practical background in assessing the aesthetic value of works of art.

Emergence is much discussed by both philosophers and scientists. But, as noted by Mitchell (2012), there is a significant gulf; philosophers and scientists talk past each other. We contend that this is because philosophers and scientists typically mean different things by emergence, leading us to distinguish being emergence and pattern emergence. While related to distinctions offered by others between, for example, strong/weak emergence or epistemic/ontological emergence (Clayton, 2004, pp. 9–11), we argue that the being vs. pattern distinction better (...) captures what the two groups are addressing. In identifying pattern emergence as the central concern of scientists, however, we do not mean that pattern emergence is of no interest to philosophers. Rather, we argue that philosophers should attend to, and even contribute to, discussions of pattern emergence. But it is important that this discussion be distinguished, not conflated, with discussions of being emergence. In the following section we explicate the notion of being emergence and show how it has been the focus of many philosophical discussions, historical and contemporary. In section 3 we turn to pattern emergence, briefly presenting a few of the ways it figures in the discussions of scientists (and philosophers of science who contribute to these discussions in science). Finally, in sections 4 and 5, we consider the relevance of pattern emergence to several central topics in philosophy of biology: the emergence of complexity, of control, and of goal-directedness in biological systems.

The first book of Horace's Odes features a pattern, similar to that of the Parade Odes, in which tree names are introduced without repetition. This pattern is not simply a formal feature but contributes to a motif, which begins in Book I of the Odes but continues into Books 2 and 3, in which the relationship between humans and trees is depicted as a symbol of poetic mastery. By demonstrating his ability to create and arrange a poetic grove, (...) Horace thus announces his command of the lyric genre. (shrink)

Among philosophical analyses of Darwin’s Origin, a standard view says the theory presented there had no concrete observational consequences against which it might be checked. I challenge this idea with a new analysis of Darwin’s principal geographical distribution observations and how they connect to his common ancestry hypothesis.

Let us look to America, not in order to make a servile copy of the institutions that she has established, but to gain a clearer view of the polity that will be the best for us; let us look there less to find examples than instruction; let us borrow from her the principles, rather than the details, of her laws. The laws of the French republic may be, and ought to be in many cases, different from those which govern the (...) United States; but the principles on which the American constitutions rest, those principles of order, of the balance of powers, of true liberty, of deep and sincere respect for right, are indispensable to all republics; they ought to be common to all …. —Alexis de Tocqueville Democracy in America.

This review is focused on recent advances in our understanding of the development of coordinated cell polarity, through experiments on the Drosophila compound eye. Each eye facet (or “ommatidium”) contains a set of eight photoreceptor cells, placed so that their rhabdomeres form an asymmetric trapezoid. The array of ommatidia is organized so that these trapezoids are aligned in two mirror-image fields, dorsal and ventral to the eye midline (or “equator”). The development of this pattern depends on two systems of (...) positional information that inform the cluster of cells that will form an ommatidium of anterior/posterior (a/p) and dorsal/ventral (d/v) direction. The former (a/p) is encoded by a progressive wave of development (the morphogenetic furrow). The latter (d/v) involves molecules known to act in tissue polarity in other organs and organisms. Our understanding of the function of these molecules rests not only on their mutant phenotypes, biochemistry, and expression patterns, but also on the spatial effects when mutant patches of cells are made (genetic mosaics).

“If, then, we are really to find out what is true and what is false, we must direct our attention to the role of any particular item in the whole of which it is a part.”—Wertheimer: On Truth.In these days of Gestalttheorie it seems not untimely to inquire whether psychology itself does not stand in need of being recognized as a configuration of complementary parts. The suggestion, it is true, tends at the first to be repudiated by the implacability of (...) the schools with their claims and counterclaims resounding on every side. On further analysis, however, such controversy seems to acquire the very different significance of having permitted certain partial aspects of the whole field to become well-articulated, even if in somewhat exaggerated form. In other words, if there is any underlying unity in psychology, then the very overstatements of the school zealots while unwittingly defeating their own purpose may have been doing the science a real service by throwing its basic pattern into bold relief. In broadest terms this seems to describe what has been happening in psychology in the recent past and to define the present stage of its development. (shrink)

Paul Ricoeur clearly sought to differentiate between and keep separate his philosophical and theological intellectual endeavors. This essay brings into relief a deep, implicit, recapitulative pattern in Ricoeur’s thinking that cuts across this explicit “conceptual asceticism.” Specifically, it highlights this recapitulative pattern in Ricoeur’s treatment of prophecy in the Hebrew Bible; his understanding of utopia and ideology; the functioning of symbols in The Symbolism of Evil and of sublimation in Freud and Philosophy . On these topics Ricoeur extended (...) his typical generosity toward all that might appear to be outdated, primitive, and even regressive in our collective and personal humanity. The frequently recapitulative nature of Ricoeur’s insights indicates the importance not just of the content of his thought but also the way in which he did his thinking, a pattern which above all was generous, even to a fault.
