Imagine that the person you see through the looking glass is a real person, with her own experiences, living in an environment that is the mirror-reverse of yours. You look at your right-hand glove as you put it on your right hand; she looks at her left-hand glove as she puts it on her left hand. You feel your heart beating on your left side; she feels her heart beating on her right side. You (...) hear a bird chirping out the window to your left; she hears a bird chirping out the window to her right. Is there any difference between your experience—your what-it-is-like phenomenal character—and hers? She is looking at her left-hand glove, the mirror-reverse of you as you look at your right-hand glove. Does she see what you see, a right-hand glove, or the reverse of what you see, a left-hand glove? Since her environment is the mirror-reverse of yours, and she seems to get by in it just fine, you'd probably assume, if you had to guess, that she sees it correctly. She is looking at her left-hand glove, after all. So it stands to reason that she is having an experience as of a left-hand glove, not a right-hand glove. And it stands to reason—it seems obvious—that an experience as of a left-hand glove differs in what it is like from an experience as of a right-hand glove. In this paper, I will argue that this last presupposition, obvious though it may seem, is false. I'll argue that (unless dualism is true) there is no intrinsic difference between what it is like to experience a left-hand glove and what it is like to experience a right-hand glove: if there are any relevant experiential differences, these are either merely comparative (differences in what it is like to compare gloves) or cognitive (differences in what it is like to bring an experience of a glove under a concept like LEFT or RIGHT). So your mirror-reverse twin, who won't differ from you in what she is comparing or thinking, will have the same (type of) experience as you. I'll call the position I am arguing against orientation–experience categoricalism, and the position I am arguing for orientation–experience relationism. Orientation–experience relationism is a surprising thesis, one whose falsity you might take for granted. I will argue for it by cases. Things go wrong for the orientation–experience categoricalist in one sort of way if we imagine that you and your mirror-twin's experiences differ: basically, this leads to absurdity if we imagine that you and she both live at a world with a non-orientable spatial topology (in the sense in which a Möbius strip or Klein bottle are non-orientable). Things go wrong for the orientation–experience categoricalist in a different sort of way if we assume that you and your twin would experience the same, but that someone else might have the experience that we were just imagining that your twin might have. Under these assumptions, we have to accept the existence of partial zombies, who lack the relevant phenomenology but behave as if they have it, at very close, empirically possible worlds. In an appendix, I argue that property dualism is the best alternative for those who cannot bring themselves to accept orientation-experience relationism. (shrink)

Following the collapse of communism and the decline of Marxism, some commentators have claimed that we have reached the 'end of history' and that the distinction between Left and Right can be forgotten. In this book - which was a tremendous success in Italy - Norberto Bobbio challenges these views, arguing that the fundamental political distinction between Left and Right, which has shaped the two centuries since the French Revolution, has continuing relevance today. Bobbio explores the (...) grounds of this elusive distinction and argues that Left and Right are ultimately divided by different attitudes to equality. He carefully defines the nature of equality and inequality in relative rather than absolute terms. Left and Right is a timely and persuasively argued account of the basic parameters of political action and debate in the modern world - parameters which have remained constant despite the pace of social change. The book will be widely read and, as in Italy, it will have an impact far beyond the academic domain. (shrink)

A critique of ‘beyond left and right’ ideologies, from red Toryism to techno-libertarianism.

The terms ‘left’ and ‘right’ cannot describe two extremes of a single ideological dimension. Instead, a bi-dimensional model including socio-cultural and socio-economic facets of leftism/rightism is postulated. Several studies conducted in the USA and Western Europe show a relative coherence of left-wing and right-wing orientation regarding both dimensions, whereas very diverse patterns can be found in the countries of Eastern Europe. In Poland cultural and economic leftism-rightism seem to be clearly negatively related. The general hypothesis in (...) this paper claims that such ideological inconsistency is a product of coherence at the level of preferences for values, i.e. covariance within individualistic as well as within collectivist values. Based on a survey study conducted on a representative sample of Poles, it was shown that preferences for values made up two distinct dimensions: Openness to change vs Conservation, and Self-enhancement vs Self-transcendence. They are positively related but have fundamentally different relationships with political self-identification and ideology. (shrink)

The last decade has seen a dramatic increase in studies on the development, function and evolution of asymmetries in vertebrates, including amphibians. Here we discuss current knowledge of behavioral and anatomical asymmetries in amphibians. Behavioral laterality in the response of both adult and larval anurans to presumed predators and competitors is strong and may be related, respectively, to laterality in the telencephalon of adults and the Mauthner neurons of tadpoles. These behavior lateralities, however, do not seem to correlate with visceral (...) asymmetries in the same animals. We briefly compare what is known about the evolution and development of asymmetry in the structure and function of amphibians with what is known about asymmetries in other chordate and non‐chordate groups. Available data suggest that the majority of asymmetries in amphibians fall into two independent groups: (1) related to situs viscerum and (2) of a neurobehavioral nature. We find little evidence linking these two groups, which implies different developmental regulatory pathways and independent evolutionary histories for visceral and telencephalic lateralizations. Studies of animals other than standard model species are essential to test hypotheses about the evolution of laterality in amphibians and other chordates.

The only contemporary moral problems text to focus directly on the ethics of current, divisive political issues, Ethics, Left and Right features newly commissioned essays on twenty contentious debates, written expressly with undergraduate students in mind. It offers two position pieces on each issue--one left-leaning, one right--followed by a reply from each author, giving you and your students the opportunity to engage in in-depth discussions of serious issues. The essays cover compelling topics including whether we should (...) have an "America First" approach to policy, whether it's okay to have religious tests for immigration, the merits of political correctness, the ethics of voting, whether progressive taxation is legitimate, and what to make of accusations of privilege. Case studies at the end of every main contribution encourage students to examine related problems and/or delve deeper into the current issue. (shrink)

Round-table discussion on the topic of the title. Difficult to abstract more accurately.

This paper explores the implications of libertarianism for welfare policy. There are two central arguments. First, the paper argues that if one adopts a libertarian framework, it makes most sense to be a Lockean right-libertarian. Second, the paper argues that this form of libertarianism leads to the endorsement of a fairly extensive set of redistributive welfare programs. Specifically, the paper argues that Lockean right-libertarians are committed to endorsing welfare programs under which the receipt of benefits is conditional on (...) meeting a work requirement, and also endorsing some form of publicly funded jobs of last resort for potential welfare recipients.

I consider an argument, due to Geoffrey Lee, that we can know a priori from the left-right asymmetrical character of experience that our brains are left-right asymmetrical. Lee's argument assumes a premise he calls relationism, which I show is well-supported by the best philosophical picture of spacetime. I explain why Lee's relationism is compatible with left-right asymmetrical laws. I then show that the conclusion of Lee's argument is not as strong or surprising as he (...) makes it out to be.

Honeybees show lateral asymmetry in both learning about odours associated with reward and recalling memory of these associations. We have extended this research to show that bees exhibit lateral biases in their initial response to odours: viz., turning towards the source of an odour presented on their right side and turning away from it when presented on their left side. The odours we presented were the main component of the alarm pheromone, iso-amyl acetate (IAA), and four floral scents. (...) The significant bias to turn towards IAA odour on the right and away from it on the left is, we argue, a lateralization of the fight-flight response elicited by this pheromone. It contrasts to an absence of any asymmetry in the turning response to an odour of the flowers on which the bees had been feeding prior to testing: to this odour they turned towards when it was presented on either the left or right side. Lemon and orange odours were responded to differently on the left and right sides (towards on the right, away on the left) but no asymmetry was found in responses to rose odour. Our results show that side biases are present even in the initial, orienting response of bees to certain odours. (shrink)

In Plato's Phaedrus, Socrates offers two speeches, the first portraying madness as mere disease, the second celebrating madness as divine inspiration. Each speech is correct, says Socrates, though neither is complete. The two kinds of madness are like the left and right sides of a living body: no account that focuses on just one half can be adequate. In a recent paper, Hugh Benson gives a left-handed speech about a psychic condition endemic among mathematicians: dianoia. Benson acknowledges (...) that his account is one-sided, but only hints at the virtues of right-handed dianoia. This note sketches a somewhat fuller picture. (shrink)

The ventrolateral prefrontal cortex plays a pivotal role in cognitive reappraisal. Previous studies suggested a functional asymmetry of the bilateral VLPFC, but the evidence is still insufficient during cognitive reappraisal. In this study, we conducted an online single-pulse transcranial magnetic stimulation to investigate the causal and distinct roles of the left and right VLPFC in reappraisal. Participants were instructed to reappraise or attend to pictures depicting social exclusion scenarios while the spTMS was applied over the left or (...) right VLPFC of the participants’ brains. The results showed that spTMS of either the left or the right VLPFC would increase reappraisal difficulty. Meanwhile, the outcome of reappraisal significantly deteriorated when the right VLPFC was temporally interrupted by spTMS, while the verbal fluency during oral reporting of the reappraisal strategy was significantly reduced when the left VLPFC was interrupted by spTMS. Taken together, these findings provide causal evidence for the involvement of left and right VLPFC with distinct roles: while the left VLPFC is responsible for the linguistic especially semantic process of generating and selecting appraisals according to the goal of emotion regulation, the right VLPFC plays a critical role in inhibiting inappropriate negative emotions and thoughts generated by the effective scenarios. These findings deepen our understanding of the neurocognitive mechanism of emotion regulation. (shrink)

Both general publics and elites have long used labels of left and right as cues for political communication and vote choice in Western democracies. This study examines the utility of these spatial semantics as means of encapsulating major political cleavages in East Asian democracies. Through analysis of public opinion surveys, we investigate the influence of organizational affiliation; views on socio-economic, religious, and issues, as well as attitudes toward the political system, as anchors of public understanding of the leftWestern (...) leftright scale in South Korea, the Philippines, and Taiwan, left level of ideological conceptualization are likely related to party system development and democratic experience.

The aim of this review is to summarize some of the recent advances in molecular embryology that help to explain the pathogenesis of holoprosencephaly (HPE), or its related malformation in model organisms, cyclopia, and laterality defects in humans, derived from detailed analysis of similar malformations in animal models. Recently, defects in several developmental pathways including those operated by the Sonic hedgehog and Nodal signaling factors have been implicated as causes of HPE or laterality defects in humans. Here we summarize the (...) findings in animal models that indicate that both defects can be explained by mechanisms that relate to the proper development of the axial midline in vertebrates.

Explores the complex relationship between avant-garde art and politics to reveal links with right-wing or fascist causes.

Sometimes we hear that “right” and “left” are no longer relevant. Here is a redefinition of right and left so that the terms remain relevant. Standardly, a “left” politics is associated with equality, progress, planning, openness, or criticism, and a “right” politics with inequality, regress, lack of planning, closedness, or an uncritical attitude. Against these suggestions, I define “left” as a synecdochal politics, a politics which takes a part to stand for the whole, (...) and searches for a policy, and “right” as the opposite, an unsynecdochal politics, a politics which does not take a part to stand for the whole, and searches for a sense of balance, order and proportion. This redefinition is supported by empirical observations made by psychologists about the nature of the right and left hemispheres of the brain. “Left” has been considered superior to “right” for at least a century. But this is a mistake since both left and right are as necessary for a successful politics as they are for successful brain function. But they are not equal in status, for in politics, as in psychology, we have to recognise as a fundamental principle, “the necessity of the left but the superiority of the right.”. (shrink)

Using fMRI, we investigated how right temporal lobe gliomas affecting the posterior superior temporal sulcus alter neural processing observed during speech perception and production tasks. Behavioural language testing showed that three pre-operative neurosurgical patients with grade 2, grade 3 or grade 4 tumours had the same pattern of mild language impairment in the domains of object naming and written word comprehension. When matching heard words for semantic relatedness (a speech perception task), these patients showed under-activation in the tumour infiltrated (...) right superior temporal lobe compared to 61 neurotypical participants and 16 patients with tumours that preserved the right postero-superior temporal lobe, with enhanced activation within the (tumour-free) contralateral left superior temporal lobe. In contrast, when correctly naming objects (a speech production task), the patients with right postero-superior temporal lobe tumours showed higher activation than both control groups in the same right postero-superior temporal lobe region that was under-activated during auditory semantic matching. The task dependent pattern of under-activation during the auditory speech task and over-activation during object naming was also observed in eight stroke patients with right hemisphere infarcts that affected the right postero-superior temporal lobe compared to eight stroke patients with right hemisphere infarcts that spared it. These task-specific and site-specific cross-pathology effects highlight the importance of the right temporal lobe for language processing and motivate further study of how right temporal lobe tumours affect language performance and neural reorganisation. These findings may have important implications for surgical management of these patients, as knowledge of the regions showing functional reorganisation may help to avoid their inadvertent damage during neurosurgery.

Cerebral lateralization is associated with differences in brain organization and handedness is seen as its main marker. In order to verify the hypothesis that differences in brain organization tend to be associated with different patterns of interests and abilities, 379 normal left-handed subjects (221 women, aged 18 – 72 years) and 366 normal right-handed subjects (256 women, aged 18 – 72 years) were interviewed about their interests and special abilities. The following interests and special abilities were studied: singing, (...) playing an instrument, dancing, painting, acting, foreign language skills, sports skills, and writing poetry.The results in the left-handers group showed that there is a significantly higher percentage of subjects with a pronounced interest in playing an instrument. In the group of right-handers, the study demonstrated a significantly higher percentage of subjects specifically interested in learning foreign languages. With respect to the abilities, a significantly higher incidence of participants with vocal, instrumental, sports, and foreign language skills was found in the left-handers’ group. Differences in functional cerebral organization between left- and right-handers were suggested as possible explanation for the relationship of handedness with special abilities. (shrink)

This article examines the formation of consciousness among women at the beginning stages of the women's movement. The author analyzes the complexity of pathways to feminism across the political spectrum, comparing women who were active on the Left in Students for a Democratic Society with women active in the leading conservative organization of the 1960s, Young Americans for Freedom. She finds an unexpected division among women in both groups between those who identify discrimination by their male peers and those (...) who do not. The author argues there are three stages in the formation of feminist consciousness: identification of inequality or mistreatment, discovering a language or framing by which to interpret these experiences, and the social construction of a collective identity. Factors for each of these three stages that help or hinder the formation of feminist consciousness are discussed. (shrink)
