In this paper, we will consider the neuro-cognitive systems involved in mediating morality. Five main claims will be made. First, that there are multiple, partially separable neuro-cognitive architectures that mediate specific aspects of morality: social convention, care-based morality, disgust-based morality and fairness/justice. Second, that all aspects of morality, including social convention, involve affect. Third, that the neural system particularly important for social convention, given its role in mediating anger and responding to angry expressions, is ventrolateral prefrontal cortex. Fourth, that the (...) neural systems particularly important for care-based morality are the amygdala and medial orbital frontal cortex. Fifth, that while Theory of Mind is not a prerequisite for the development of affect-based 'automatic moral attitudes', it is critically involved in many aspects of moral reasoning. (shrink)

The abilities to attribute an action to its proper agent and to understand its meaning when it is produced by someone else are basic aspects of human social communication. Several psychiatric syndromes, such as schizophrenia, seem to lead to a dysfunction of the awareness of one’s own action as well as of recognition of actions performed by other. Such syndromes offer a framework for studying the determinants of agency, the ability to correctly attribute actions to their veridical source. Thirty normal (...) subjects and 30 schizophrenic patients with and without hallucinations and/or delusional experiences were required to execute simple finger and wrist movements, without direct visual control of their hand. The image of either their own hand or an alien hand executing the same or a different movement was presented on a TV-screen in real time. The task for the subjects was to discriminate whether the hand presented on the screen was their own or not. Hallucinating and deluded schizophrenic patients were more impaired in discriminating their own hand from the alien one than the non-hallucinating ones, and tended to misattribute the alien hand to themselves. Results are discussed according to a model of action control. A tentative description of the mechanisms leading to action consciousness is proposed. (shrink)

The Soviet philosophical scene has experienced remarkable growth since the innovations of the 50's and the renovations of the 60's. This volume of Sovietica is intended by the editors as a finger on the pulse of the Marxist-Leninist corpus philosophicum as we enter the 1970's. Published in the years between 1960 and 1970, the Filosofskaja en ciklopedija (FE) has replaced the Kratkij filosofskij slovar' (Short Philo sophic Dictionary: 1939, 1941, 1951 and 1954) and the Filosofskij slovar' (Philosophic Dictionary: 1963). (...) It is an impressive work - 2994 pages in five volumes (I, 1960, 504 pp.; II, 1962, 575 pp.; III, 1964, 584 pp.; IV, 1967, 591 pp.; V, 1970, 740 pp.), with the editors and authors representing all the contemporary Soviet philosophers of note. The FE has been extensively reviewed in Kommunist (1972, 5, 119-127) and in Studies in Soviet Thought [beginning with SST 12 (1972) 4]. Restrictions of space have forced us to omit much that was originally to be included. The same limitations have obliged us to deviate from the initial methodological rule which was 'to include only complete, un abridged articles' - in order to avoid distortion by selection. Only two articles have been shortened: only the basic portion of 'science' has been included; we have dropped 'natural science', 'sciences on man and society', and 'classification of sciences' (a total of thirteen pages in Russian) - this last with regret and with apologies to Professor Kedrov.

In lieu of an abstract, here is a brief excerpt of the content:“An Immoderate Taste for Truth”: Censoring History in Baudelaire’s “Les bijoux”E. S. Burt (bio)In May 1949, a French Court of Appeals reversed an 1857 decision condemning six poems from Les fleurs du mal for obscenity, in a signal case of a public lifting of a ban against some lyric poems. 1 Among the several interesting features of this case not the least is the decision to proceed against the (...) work in the first place. For lyric poetry does not appear an attractive target for censorship. Its subject matter and formalism remove it far enough from the experience of most readers that Gustave Flaubert, fresh from his troubles with the court over Madame Bovary, could express his surprise at the government’s attack: “This is new,” he wrote to Baudelaire, “this pursuit of a volume of verse.” While Flaubert’s comment was in point of fact inaccurate, he puts his finger on a problem worth considering. 2 Here we have a work that must seem naturally exempt from state intervention, by virtue of a deliberate retreat from risky political subjects, and it nonetheless did get censored by the state. Can anything be learned about “normal” state censorship from this exceptional case? [End Page 19]A key factor in the government’s decision to pursue the book, according to the prosecutor Pinard, was that these poems would prove accessible to a large audience: 3 “An immoral book that had no chance of being read or understood would not be pursued” [1208], he states. In his argument, as in the judgment by the court that the condemned poems “lead necessarily to the exciting of the senses by a coarse realism offensive to modesty” [1182], the assumption is that the work is extraordinarily available, its pictures immediately referable to ordinary experience. In the six condemned poems, language is judged to be not a veil but a tool, and a sex tool at that. “Despite an effort of style” [1182], the poetic situation—in most of the poems that of the boudoir—is painted in a language insufficiently flowery. 4A further interesting feature in the case is that when it comes up again, under DeGaulle’s Fourth Republic, the court summarily dismisses the 1857 judgment of coarse realism as just one possible interpretation, and a forced one at that. Instead, the 1949 court finds that the poems are self-referential, symbolic entities that do not represent ordinary experience:If some pictures, on account of their originality, were able to alarm some minds upon first publication and appeared to the first judges as offensive to morality, such an appraisal, attaching itself only to a realistic interpretation of the poems and neglecting their symbolic meaning, has proved to be of an arbitrary character, unratified by public opinion or by the judgment of the literary world.[St. John-Stevas 249]The shocking representations of 1857, outraging morality, are now understood to deliver the Wordsworthian “shock of mild surprise” by which we recognize the original work of art. In 1949, the poems are precious artifacts; their language is not realistic but symbolical; its sensuous forms reveal an inner, spiritual meaning.A crucial resemblance can be discerned between the actions taken by the two courts: both make their judgments in terms of a “reading pact,” a set of “artificial rules” [1206] that are presumed to govern reading and to have currency in the context. Les fleurs gets policed in the name of this generic purity, with the prosecutor Pinard calling “the judge... a sentinel who must not let the border be crossed” [1206] and the 1949 decision confirming the opinion of the literary world that the supposed transgression against public morality was in point of fact a transformation in the rules regulating the narrow confines of lyric poetry. 5This concern that texts be framed by a reading pact aimed at constraining their interpretation is worth considering in any discussion of censorship that wants to move from the level of pragmatics to that of theory. It leads to queries about the possibility of getting rid of state censorship entirely and about the state’s interest, as guardian and overseer of the archive, in the institutionalization and...

Arithmetical cognition is the result of enculturation. On a personal level of analysis, enculturation is a process of structured cultural learning that leads to the acquisition of evolutionarily recent, socio-culturally shaped arithmetical practices. On a sub-personal level, enculturation is realized by learning driven plasticity and learning driven bodily adaptability, which leads to the emergence of new neural circuitry and bodily action patterns. While learning driven plasticity in the case of arithmetical practices is not consistent with modularist theories of mental architecture, (...) it can be enriched by the theory of neural reuse. According to neural reuse, cerebral regions are reused to contribute to multiple neural circuits in functionally constrained ways throughout ontogeny. By hypothesis, learning driven plasticity is complemented by learning driven bodily adaptability, which suggests that there is an interesting functional relationship between finger gnosis, finger counting, and arithmetical practices. The emerging perspective on enculturated arithmetical cognition will be complemented by considerations on associated developmental and acquired disorders, namely developmental dyscalculia and acquired acalculia. The upshot is that we need to take the cerebral, extra-cerebral bodily, and socio-cultural dimensions of enculturation into account in order to arrive at a better understanding of the phylogenetic and ontogenetic conditions of arithmetical cognition.

We review the major phenomena of skilled typing and propose a model for the control of the hands and fingers during typing. The model is based upon an Activation‐Trigger‐Schema system in which a hierarchical structure of schemata directs the selection of the letters to be typed and, then, controls the hand and finger movements by a cooperative, relaxation algorithm. The interactions of the patterns of activation and inhibition among the schemata determine the temporal ordering for launching the keystrokes. To (...) account for the phenomena of doubling errors, the model has only “type” schemata—no “token” schemata—with only a weak binding between the special schema that signals a doubling, and its argument. The model exists as a working computer simulation and produces an output display of the hands and fingers moving over the keyboard. It reproduces some of the major phenomena of typing, including the interkeystroke interval times, the pattern of transposition errors found in skilled typists, and doubling errors. Although the model is clearly inadequate or wrong in some of its features and assumptions, it serves as a useful first approximation for the understanding of skilled typing. (shrink)

The ratio of index- and ring-finger lengths is thought to be related to prenatal androgen exposure, and in many, though not all, populations, men have a lower average digit ratio than do women. In many studies an inverse relationship has been observed, among both men and women, between 2D:4D ratio and measures of athletic ability. It has been further suggested that, in hunter-gatherer populations, 2D:4D ratio might also be negatively correlated with hunting ability, itself assumed to be contingent on (...) athleticism. This hypothesis has been tested using endurance running performance among runners from a Western, educated, and industrialized population as a proximate measure of hunting ability. However, it has not previously been tested among actual hunter-gatherers using more ecologically valid measures of hunting ability and success. The current study addresses this question among Tanzanian Hadza hunter-gatherers. I employ a novel method of assessing hunting reputation that, unlike previous methods, allows granular distinctions to be made between hunters at all levels of perceived ability. I find no statistically significant relationship between digit ratio and either hunting reputation or two important hunting skills. I confirm that Hadza men have higher mean 2D:4D ratios than men in many Western populations. I discuss the notion that 2D:4D ratio may be the consequence of an allometric scaling relationship between relative and absolute finger lengths. Although it is difficult to draw clear conclusions from these results, the current study provides no support for the theorized relationship between 2D:4D ratio and hunting skill. (shrink)

The present study investigates shared representations of syntactic knowledge in music and action. We examined whether expectancy violations in musical harmonic sequences are also perceived as violations of the movement sequences necessary to produce them. Pianists imitated silent videos showing one hand playing chord sequences on a muted keyboard. Results indicate that, despite the absence of auditory feedback, imitation of a chord is fastest when it is congruent with the preceding harmonic context. This suggests that the harmonic rules implied by (...) observed actions induce expectations that influence action execution. As evidence that these predictions are derived at a high representational level, imitation was more accurate for harmonically incongruent chords than for congruent chords executed with unconventional fingering. The magnitude of the effects of context and goal prioritization increased with musical training. Thus, musical training may lead to a domain-general representation of musical grammar, i.e., to a grammar of action. (shrink)

When did historians begin to put quotation marks around the wordreal? There are many examples of this habit and some of them will be set forth as evidence in what follows.

Today we find them so familiar they hardly need to be written and they are more frequently consigned to the everyday repertoire of silent gesture: two fingers on either hand clutch at the (...) air as if they meant to tickle the flanks of the invisible beast between them. The popular term is “scare-quotes,” a pun on the word “scarecrow.” Its etymology is revealing: just as a mere representation of a body in a field may scare off birds, so too scare-quotes permit someone to deploy a word without sincere commitment to what it normally means. But further reflection tells us that the effects are not so similar after all: To use a term without sincerity robs it of its original meaning and holds up its lifeless corpse to ridicule. The more knowing sort of crow can settle on the shoulder of the figure on the pole precisely because it recognizes that such a sorry excuse for a man can in fact harm no one. Similarly when one putsrealityin quotation marks we are put in mind of the living concept but we are immediately alerted to the fact that, for the user at least, the new term enjoys no metaphysical prestige. How did this happen? When and why did the single most privileged word in the entire lexicon of metaphysics begin to lose its authority such that in certain spheres of intellectual sophistication its sincere use would only seem an embarrassment and a sign of naïveté?

This article investigates a little-known computational and mnemonic device invented in c. 1348 by the English Carmelite friar John of Northampton, the details of which are known from a treatise written in or before 1394 by Richard Maidstone, a theologian and fellow member of the Carmelite Order. John’s anulus took the form of a metal finger ring whose wearer could use the complex arrangement of its alphanumeric inscriptions to make a range of calendrical calculations as well as predict the (...) times of the mean conjunctions of the sun and moon. In addition to reconstructing the principles by which this unusual instrument functioned, the article concludes by placing the anulus in the wider context of the computistical and astronomical sciences practised in fourteenth-century Europe.

Predictable somatosensory feedback leads to a reduction in tactile sensitivity. This phenomenon, called tactile suppression, relies on a mechanism that uses an efference copy of motor commands to help select relevant aspects of incoming sensory signals. We investigated whether tactile suppression is modulated by the task-relevancy of the predicted consequences of movement and the intensity of related somatosensory feedback signals. Participants reached to a target region in the air in front of a screen; visual or tactile feedback indicated the reach (...) was successful. Furthermore, tactile feedback intensity varied across two groups of participants. We measured tactile suppression by comparing detection thresholds for a probing vibration applied to the finger either early or late during reach and at rest. As expected, we found an overall decrease in late-reach suppression, as no touch was involved at the end of the reach. We observed an increase in the degree of tactile suppression when strong tactile feedback was given at the end of the reach, compared to when weak tactile feedback or visual feedback was given. Our results suggest that the extent of tactile suppression can be adapted to different demands of somatosensory processing. Downregulation of this mechanism is invoked only when the consequences of missing a weak movement sequence are severe for the task. The decisive factor for the presence of tactile suppression seems not to be the predicted action effect as such, but the need to detect and process anticipated feedback signals occurring during movement.

Tremor of the upper extremity is a significant cause of disability in some patients with multiple sclerosis. The MS tremor is complex because it contains an ataxic intentional tremor component due to the involvement of the cerebellum and cerebellar outflow pathways by MS plaques, which makes the MS tremor, in general, less responsive to medications or deep brain stimulation than those associated with essential tremor or Parkinson's disease. The cerebellar component has been thought to be the main reason for making (...) DBS less effective, although it is not clear whether it is due to the lack of suppression of the ataxic tremor by DBS or else. The goal of this study was to clarify the effect of DBS on cerebellar tremor compared to non-cerebellar tremor in a patient with MS. By wearing an accelerometer on the index finger of each hand, we were able to quantitatively characterize kinetic tremor by frequency and amplitude, with cerebellar ataxia component on one hand and that without cerebellar component on the other hand, at the beginning and end of the hand movement approaching a target at DBS Off and On status. We found that cerebellar tremor surprisingly had as good a response to DBS as the tremor without a cerebellar component, but the function control on cerebellar tremor was not as good due to its distal oscillation, which made the amplitude of tremor increasingly greater as it approached the target. This explains why cerebellar tremor or MS tremor with cerebellar component has a poor functional transformation even with a good percentage of tremor control. This case study provides a better understanding of the effect of DBS on cerebellar tremor and MS tremor by using a wearable device, which could help future studies improve patient selection and outcome prediction for DBS treatment of this disabling tremor.

Retroviruses encode a small, basic nucleocapsid (NC) protein that is found complexed to genomic RNA within the viral particle. The NC protein appears to function not only in a histone‐like manner in packaging the RNA into the particle but also in specifically selecting the viral genomic RNA for packaging. A cysteine‐histidine (cys‐his) region, usually composed of 14 amino acids and reminiscent of the ‘zinc fingers’ of transcription factors, is the only highly conserved sequence element among the retroviral NC proteins. This (...) review discusses the biochemical properties of NC, and its possible role(s) in retroviral replication. We also speculate on how the biochemical properties may relate to its function in RNA recognition and packaging. (shrink)

PurposeChildhood onset speech fluency disorder is possibly related to dopaminergic dysfunction. Mesencephalic hyperechogenicity detected by transcranial ultrasound might be seen as an indirect marker of dopaminergic dysfunction. We here determined whether adults who stutter since childhood show ME.MethodsWe performed TCS in ten AWS and ten matched adults who never stuttered. We also assessed motor performance in finger tapping and in the 25 Foot Walking test.ResultsCompared to controls, AWS showed enlarged ME on either side. Finger tapping was slower in (...) AWS. Walking cadence, i.e., the ratio of number of steps by time, tended to be higher in AWS than in control participants.DiscussionThe results demonstrate a motor deficit in AWS linked to dopaminergic dysfunction and extending beyond speech. Since iron deposits evolve in childhood and shrink thereafter, ME might serve as an easily quantifiable biomarker helping to predict the risk of persistency in children who stutter. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 30, Number 1, April 2004, pp. 51-85 Scratched Fingers, Ruined Lives, and Acknowledged Lesser Goods CASS WELLER It is not contrary to reason to prefer the destruction of the whole world to the scratching of my finger. It is not contrary to reason for me to choose my total ruin, to prevent the least uneasiness of an Indian, or person wholly unknown to me. It (...) is as little contrary to reason to prefer even my own acknowledged lesser good to my greater, and have a more ardent affection for the former than the latter. (T 2.3.3.6; SBN 416)1 Everyone is familiar with the cases Hume parades in this passage when he dramatically displays just how far one's preferences and other passions can go without being contrary to reason. His general point is tediously clear. Whatever failing there is in one who prefers the destruction of the world to the scratching of his finger or chooses his total ruin to prevent the least uneasiness of a person wholly unknown to him, it is not a failing of reason, unless this preference and choice involve false suppositions of fact, existence, or mathematics. But they do not according to Hume. So they are not contrary to reason. At the same time, anyone who is given to worrying and fretting over the text will be initially somewhat at a loss to explain in any further detail the nature of the phenomena Hume flaunts as not flouting reason and how they relate to one another. For example, is the notion of preference at work that of a settled judgment of value or that of a blind impulse to be understood only in terms of strength of desire? Is the character Hume inhabits in the first person one who simply finds himself with a blind urge to keep his finger scratch-free or one who Cass Weiler is Associate Professor of Philosophy, University of Washington, Seattle, WA 98195, USA. e-mail: [email protected] 52 Cass Weller has a settled policy of keeping his finger scratch-free viewed as more valuable than anything else. Is preferring my lesser good to my acknowledged greater good the practical counterpart of self-consciously believing that Ï• and not p? Or is it, rather, a common form of weakness? And if so, how is it related to the two previous cases? Although most discussions of Hume's views on practical reason refer to this passage, I know of no extended discussion of the three notorious cases.2 This is no doubt due in part to the fact that the details do not really matter for understanding the main point. A mental state not involving a false belief of experience or a priori reason cannot be contrary to reason.3 Nevertheless, I think it is a good idea to try and figure out just what Hume is saying and that by digging right here we may hope to uncover important aspects of Hume's theory of evaluation, motive, and reason. The task is to get a more detailed view of Hume's own theoretical understanding of the preferences and choices he exhibits as not contrary to reason, in particular whether a preference is an evaluative attitude, and how it may conflict with an acknowledged interest. To this end we will have to go beyond what is adequate for a reader's understanding of the preferences in their narrow rhetorical context. Hume himself invites the reader, inadvertently or not, to look for the wider Humean explanation of preferring one's acknowledged lesser good to the greater by deploying the analogy of a one pound weight's raising a hundred through the advantage of its situation. This idea connects with other passages in the Treatise, as we shall see, in particular with Hume's discussion of the preference for the contiguous over the remote at T 3.2.7 (SBN 534-9). With a clearer view of Hume's understanding of the preferences we will be in a better position to ask about the sort of criticism persons with such preferences are subject to. And, to tip my hand, we will see that Hume... (shrink)

An investigation of some of the most contentious debates of our time, Galileo's Middle Finger describes Alice Dreger's experiences on the front lines of scientific controversy, where for two decades she has worked as an advocate for victims of unethical research while also defending the right of scientists to pursue challenging research into human identities. Dreger's own attempts to reconcile academic freedom with the pursuit of justice grew out of her research into the treatment of people born intersex (formerly (...) called hermaphrodites). The shocking history of surgical mutilation and ethical abuses conducted in the name of "normalizing" intersex children moved her to become a patient rights' activist. By bringing evidence to physicians and the public, she helped change the medical system. But even as she worked to correct these injustices, Dreger began to witness how some fellow liberal activists, motivated by identity politics, were employing lies and personal attacks to silence scientists whose data revealed inconvenient truths. Troubled, she traveled around the country digging up sources and interviewing the targets of these politically motivated campaigns. Among the subjects she covers in the book are the anthropologist Napoleon Chagnon, falsely accused in a bestselling book of committing genocide against a South American tribe; the psychologist Michael Bailey, accused of abusing transgender women; and the evolutionary biologist E. O. Wilson, accused of fomenting rightwing ideas about human nature. Galileo's Middle Finger describes Dreger's long and harrowing journey back and forth between the two camps for which she felt equal empathy: social justice warriors and researchers determined to put truth before politics.

This paper investigates modular combinations of temporal logic systems. Four combination methods are described and studied with respect to the transfer of logical properties from the component one-dimensional temporal logics to the resulting combined two-dimensional temporal logic. Three basic logical properties are analyzed, namely soundness, completeness, and decidability. Each combination method comprises three submethods that combine the languages, the inference systems, and the semantics of two one-dimensional temporal logic systems, generating families of two-dimensional temporal languages with varying expressivity and varying (...) degrees of transfer of logical properties. The temporalization method and the independent combination method are shown to transfer all three basic logical properties. The method of full join of logic systems generates a considerably more expressive language but fails to transfer completeness and decidability in several cases. So a weaker method of restricted join is proposed and shown to transfer all three basic logical properties. (shrink)

We introduce a methodology whereby an arbitrary logic system L can be enriched with temporal features to create a new system T(L). The new system is constructed by combining L with a pure propositional temporal logic T (such as linear temporal logic with Since and Until) in a special way. We refer to this method as adding a temporal dimension to L or just temporalising L. We show that the logic system T(L) preserves several properties of the original temporal logic (...) like soundness, completeness, decidability, conservativeness and separation over linear flows of time. We then focus on the temporalisation of first-order logic, and a comparison is make with other first-order approaches to the handling of time. (shrink)

We start with a formulation of classical logic in which cut is non-eliminable and then impose restrictions on the use of cut. Three Cut-and-Pay families of logics are presented, and it is shown that each family provides an (...) approximation process for full propositional classical logic when the control over the use of cut is progressively weakened. A sound and complete semantics is given for each component of each of the three families of approximated logics. One of these families is shown to possess the uniform substitution property, a new result for approximated reasoning. A tableau based decision procedure is presented for each element of the approximation families and the complexity of each decision procedure is studied. We show that there are families in which every component logic can be decided polynomially. (shrink)

This paper generalises and complements the work on combining temporal logics started by Finger and Gabbay [11, 10]. We present proofs of transference of soundness, completeness and decidability for the temporalisation of logics T for any flow of time, eliminating the original restriction that required linear time for the transference of those properties through logic combination. We also generalise such results to the external application of a multi-modal system containing any number of connectives with arbitrary arity, that respect normality.This (...) generalisation over generic flows of time propagates to other combinations of logics that can be interpreted in terms of temporalisations. In this way, the independent combination of temporal logics is studied over generic flows of time. We show the transfer of soundness, completeness and decidability for independent combination of temporal logics. Finally, we also discuss the independent combination of any finite number of normal multi-modal logics. (shrink)

In this paper we explore a generalization of traditional abduction which can simultaneously perform two different tasks: given an unprovable sequent Γ ⊢ G, find a sentence H such that Γ, H ⊢ G is provable ; given a provable sequent Γ ⊢ G, find a sentence H such that Γ ⊢ H and the proof of Γ, H ⊢ G is simpler than the proof of Γ ⊢ G . We argue that the two tasks should not be distinguished, (...) and present a general procedure for finding suitable hypotheses or lemmas. When the original sequent is provable, the abduced formula can be seen as a cut formula with respect to Gentzen's sequent calculus, so the abduction method is cut-based. Our method is based on the tableau-like system KE and we argue for its advantages over existing abduction methods based on traditional Smullyan-style Tableaux. (shrink)

We introduce a methodology whereby an arbitrary logic system L can be enriched with temporal features to create a new system T(L). The new system is constructed by combining L with a pure propositional temporal logic T (such as linear temporal logic with “Since” and “Until”) in a special way. We refer to this method as “adding a temporal dimension to L” or just “temporalising L”. We show that the logic system T(L) preserves several properties of the original temporal logic (...) like soundness, completeness, decidability, conservativeness and separation over linear flows of time. We then focus on the temporalisation of first-order logic, and a comparison is make with other first-order approaches to the handling of time. (shrink)

ABSTRACT We introduce a two-dimensional temporal logic as a formalism which enables the description of both the history of a world and the evolution of an observer's views about the history. We apply such formalism to the description of certain problems that occur in historical database systems due to updates. The historical dimension describes the history of a world according to an observer's view at a certain moment in time. The transaction dimension describes the evolution of an observer's view; changes (...) can occur in the observer's view of the present and future as well as in his views of the past. The database is seens as an observer of the history of the world. Besides describing the history of the world, the database system can also execute temporal specifications in the form of temporal actions. The two-dimensional formalism is used to describe the effects of updates in the execution of temporal actions. The detection of some problematic effects and its implementation are discussed.

The Yoga Sutras are Patanjali's classic on how to experience oneness (Samadhi) within yoga practice. Many serious yoga students want to bring the wisdom of the Sutras to their practice, but often find the text impenetrable and difficult to relate to. The Tantra of the Yoga Sutras remedies this by offering an interpretation that is uniquely relatable, teachable, and accessible. Yogi and tantric master Alan Finger shows contemporary practitioners and students that Samadhi is not something that we strive for (...) in the future, but something that we can experience now. Many interpreters of the Yoga Sutras describe Samadhi as an unreachable goal for the ordinary yogi. Finger's interpretation delivers yoga practices that are doable, with attainable and transformative results. (shrink)

During the summer of 1774, five “electric eels” survived the voyage from Surinam to Charles Towne (Charleston), South Carolina. Naturalists knew that these river fish actually only resembled eels. They also knew that that Carl Linnaeus had recently classified them as Gymnotus electricus (Linnaeus 1766; today they are Electrophorus electricus). But to most people, and even among natural philosophers, they were (and still are) loosely referred to as “eels.” For those willing to pay, a group that included physicians, gentlemen-scientists, and (...) other inquisitive minds, there was an opportunity to observe them. A promotional piece in the June 20, 1774, edition of the South-Carolina Gazette informs interested .. (shrink)
