I develop a theory of counterfactuals about relative computability, i.e. counterfactuals such as 'If the validity problem were algorithmically decidable, then the halting problem would also be algorithmically decidable,' which is true, and 'If the validity problem were algorithmically decidable, then arithmetical truth would also be algorithmically decidable,' which is false. These counterfactuals are counterpossibles, i.e. they have metaphysically impossible antecedents. They thus pose a challenge to the orthodoxy about counterfactuals, which would treat them as uniformly true. What’s more, I (...) argue that these counterpossibles don’t just appear in the periphery of relative computability theory but instead they play an ineliminable role in the development of the theory. Finally, I present and discuss a model theory for these counterfactuals that is a straightforward extension of the familiar comparative similarity models. (shrink)

This article argues that understanding any space or site relies on a knowledge of its fourth dimension - the timescape. It will explore this by situating the investigation in the museum - a place of heightened contrivance which could easily be shallowly interpreted as "mere style". It will defend a new method of investigating museum temporality which combines both phenomenology and literary theory, and will replace the idea of geo-epistemology with geochronic epistemology: an understanding of context and situation which takes (...) on time as well as spatial location. In so doing, it moves on from notions of the museum as a place out of time, situating it in the networks of meaning, power and politics in which we have lived and are living. Thus, "the whole space of the exhibition" as Lyotard said, "becomes the remains of all time": the Museum on the Edge of Forever. (shrink)

Braun explores the use of digital twin technology in medicine with a particular emphasis on the question of how such simulations can represent a person.1 In defining some first conditions for ethically justifiable forms of representation of digital twins, he argues that digital twins do not threaten an embodied person, as long as that person retains control over their simulated representation via dynamic consent, and ideally with the option to choose both form and usage of the simulation. His thoughtful elaboration (...) provides insight into the challenges inherent in interactions between a person and their digital twin, emphasising the modes of control required to respect personal modes of freedom. This individual-centric approach to the question of representation leaves out the important ethical consideration of ensuring that all, not merely some, can be represented. Braun describes dynamic consent as a necessary mode of control, arguing that where a person is unable to give consent, ‘such simulations threaten to become illegitimate representations. They would then shift the kind of interaction from representation to illegitimate forms of prediction or surveillance and thereby could lead to infringements to individual modes of freedom.’ Consequently, the implementation of digital twin technology in healthcare would seem to exclude the most vulnerable members of society from participation in and benefiting from medical innovation, ….

One famous debate in contemporary epistemology considers whether there is always one unique, epistemically rational way to respond to a given body of evidence. Generally speaking, answering “yes” to this question makes one a proponent of the Uniqueness thesis, while those who answer “no” are called “permissivists”. Another influential recent debate concerns whether non-truth-related factors can be the basis of epistemic justification, knowledge, or rational belief. Traditional theories answer “no”, and are therefore considered “purists”. However, more recently many theorists have (...) argued to the contrary, claiming that impurist factors, such as practical stakes, can sometimes encroach or even override truth-related considerations. This paper bridges the two debates by presenting and defending what I call “Impurist Permissivism”. I support Impurist Permissivism by showing how it can resist Roger White’s famous Argument from Arbitrariness (2005). (shrink)

Almost every facet of the experience of musical listening—from pitch, to rhythm, to the experience of emotion—is thought to be shaped by the meeting and thwarting of expectations. But it is unclear what kind of mental states these expectations are, what their format is, and whether they are conscious or unconscious. Here, we distinguish between different modes of musical listening, arguing that expectations play different roles in each, and we point to the need for increased collaboration between music psychologists and (...) philosophers in order to arrive at a more detailed characterisation of conscious musical experience and the role of expectations therein.

This article argues that personal medical data should be made available for scientific research, by enabling and encouraging individuals to donate their medical records once deceased, similar to the way in which they can already donate organs or bodies. This research is part of a project on posthumous medical data donation developed by the Digital Ethics Lab at the Oxford Internet Institute at the University of Oxford. Ten arguments are provided to support the need to foster posthumous medical data donation. (...) Two major risks are also identified—harm to others, and lack of control over the use of data—which could follow from unregulated donation of medical data. The argument that record-based medical research should proceed without the need to secure informed consent is rejected, and instead a voluntary and participatory approach to using personal medical data should be followed. The analysis concludes by stressing the need to develop an ethical code for data donation to minimise the risks, and offers five foundational principles for ethical medical data donation suggested as a draft code.

Dissertation Prospectus. Exploring the limits of New Mechanism as a general theory of scientific explanation, limiting its scope and proposing constraints.

David Stove's essay “The intellectual capacity of women” was first published in 1990, in the Proceedings of a Sydney philosophical society. It has been re-published twice since his death. It seems though that during his lifetime Stove himself refused to agree to its being re-printed. This raises two questions: Did Stove believe his essay on women contains mistakes? And: does it contain mistakes? The main flaws in the essay stem from a rash adoption of simplistic ideas about probability coupled with (...) a question-begging definition of capacity. The work also contains contradictions and exaggerations and some unwise forays into social history. Stove was an intelligent man so it seems likely that he would have recognised those flaws.

It is commonly held that the ascription of truth to a sentence is intersubstitutable with that very sentence. However, the simplest subclassical logics available to proponents of this view, namely K3 and LP, are hopelessly weak for many purposes. In this article, I argue that this is much more of a problem for proponents of LP than for proponents of K3. The strategies for recapturing classicality offered by proponents of LP are far less promising than those available to proponents of (...) K3. This undermines the ability of proponents LP to engage in public reasoning in classical domains. (shrink)

While the substantiation of “best interests” has received much attention, the question of how “the child” is conceptualised to ensure any action taken or decision made is in the particular child’s best interests has been largely neglected. In this paper, I argue that the lack of robust understanding of who “the child” is means that we continue to make many generalisations and category-based assumptions in determining the child’s best interests. In addressing the challenge of doing right by the individual child, (...) I propose a three-step approach based on a theoretical model of the child that avoids presumptions about child-typical needs and insists on an assessment of the child’s individual characteristics, needs, qualities, and circumstances, making it the only conceptualisation fully meeting the child centrism criterion required by children’s rights as determined by the United Nations Convention on the Rights of the Child.

Adoption may be defined as ‘the legal process through which the state establishes a parental relationship, with all its attendant rights and duties, between a child and a (set of) parent(s) where there exists no previous procreative relationship’ . In adoptions from care, state intervention effectively converts an established, or nascent, adult– child relationship into ‘family’ in the legal sense. From the state’s perspective, adoption thus entails the transfer of parental responsibilities for a child in public care to a private (...) family unit, enabling the state to permanently delegate its duties towards a child to this new unit. This seemingly straightforward legal act raises deeper philosophical questions relating to such state ‘family creation’, particularly when the child’s perspective is taken. Such a child- centric approach normatively regards children as equal moral beings, who ought to be included in actions concerning them, regardless of their capacity to form and express an opinion. Accordingly, adoption from care can be described as a moral decision, aimed at doing what is in the child’s best interests. The purpose of this chapter is to explore a suspicion of a lack of child- centrism in adoption from care practice, and to illustrate how adopted children’s rights are inferior to those of their non- adopted peers. This will shed light on a practice currently lacking transparency and accountability and will increase our understanding of how we fail to treat children as equal moral individuals in decision- making that severely impacts children’s lives.

In this dissertation I achieve the following: (1) I present motivating criteria for a general comprehensive theory of scientific explanation. I review historical approaches to modeling explanation in light of these criteria. (2) I present New Mechanist Explanation ("NME") as the leading candidate for a contemporary, complete theory of scientific explanation. (3) I present constraints on the applicability of New Mechanism in modeling biology, chemistry, and physics. I argue for the unsuitability of NME as a candidate for a general theory (...) of explanation due to its significant omissions of explanatory content and subsequent incompleteness. (4) I present arguments for the indispensable explanatory power of mathematics in science, noting that much of NME's failures are owed to its poor integration of mathematical explanation as applied to science. (5) I propose a Rational-Relational theory of explanation(“RRE”). I present RRE in detail and demonstrate it as a true working general theory of explanation which best meets the motivating criteria presented in (1). I disambiguate RRE from structural explanation ("SE"). I show that historical models of explanation, including the deductive nomological (DNE) model, statistical relevance ("SRE") model, structural model (SE) and unification model ("UE") may be successfully treated as sub-classes of explanation within the scope of RRE. I provide a rubric for selecting amongst sub-theories of explanation under RRE in the purpose of highlighting particular features of relational explanations. (6) In conclusion, I argue that philosophers of science should move forward using RRE as a general model of scientific explanation as a working alternative to the incomplete model of NME. (shrink)

In recent years, New Mechanism has become one of the most popular and widely discussed philosophical accounts of scientific explanation. Some of its proponents see it as a successor to traditional deductive nomological and statistical approaches to the philosophy of explanation. New Mechanists thus argue for the generality of their approach as a model of scientific explanation. Here we will show that the generality of NME as an account of scientific explanation is restricted. Most significantly, NME is widely recognized to (...) have trouble in accounting for explanation in traditional physics. Yet, in the face of obstacles to NME in the physical sciences, New Mechanists have yet to provide a convincing defense of the generality of their view. In this paper, I (1) summarize when and how NME works, (2) describe briefly what NME is not and can’t be, (3) outline some areas of contemporary scientific explanation where New Mechanism misses the mark; and (4) demonstrate that New Mechanism does not constitute a general theory of scientific explanation but rather covers a restricted scope of explanations.

A significant proportion of child protection cases involve care-experienced mothers, which reveals a continuous cycle of mothers who lose their children to social services after having been in state care themselves as children. While the importance of protecting children requires little explanation and forms the justificatory basis for child protection interventions, it is important to remember that care-experienced mothers were once children entrusted to the state’s care, and who arguably have been failed by the state in that their parenting opportunities (...) are significantly reduced. This paper aims to address this underexplored dilemma between protecting children and safeguarding mothering opportunities for care-experienced mothers. Appealing to the concept of solidarity, I argue that the state has an obligation to increase its compensatory efforts to secure the right of care-experienced women to not only become parents but to be able to be parents, with the aim of breaking the cycle of care experience.

While science is often presented as a body of knowledge or collection of passively accumulated facts, science should be examined and experienced as a performed process, a human endeavor connected to the ways we access the world. In this white paper, I briefly introduce the practice of science from the perspective of performance theory. By examining science in the context of performance, we may approach certain key questions about science directly. How do scientists perform experiments and practice the scientific method (...) (or, more accurately, scientific methodologies)? How does science rely on particular performer(s) and the particular contexts of those performances? What distinguishes the activity of science from other kinds of human performances? By reframing science as a human performance in the context of human practices and rituals, we more closely approach an accurate and communicable explanation of what the process of “doing science” actually is as something that humans do.

Machine learning algorithms may radically improve our ability to diagnose and treat disease. For moral, legal, and scientific reasons, it is essential that doctors and patients be able to understand and explain the predictions of these models. Scalable, customisable, and ethical solutions can be achieved by working together with relevant stakeholders, including patients, data scientists, and policy makers.

Based on a critical interpretative review of existing qualitative research investigating accounts of ‘lived experience’ of surrogates and intended parents from a relational perspective, this article proposes a typology of surrogacy arrangements. The review is based on the analysis of 39 articles, which belong to a range of different disciplines (mostly sociology, social psychology, anthropology, ethnology, and gender studies). The number of interviews in each study range from as few as seven to over one hundred. Countries covered include Australia, Canada, (...) Greece, India, Iran, Israel, Italy, Mexico, Norway, Russia, Sweden, UK, Ukraine, and the USA. Most studies focus only on surrogacy practices in one country (although often with intended parents from other countries), and some include several countries (e.g. interviewees from several countries or fieldwork in different field-sites). The proposed typology goes beyond the division between altruistic versus commercial, and traditional versus gestational surrogacy, in order to inform further research and to contribute to bioethical and policy debates on surrogacy in a transnational context. Four types of relations are identifiable: open, restricted, structured, and enmeshed. The criteria which influence these relationships are: the frequency and character of contact pre- and post-birth; expectations of both parties; the type of exchange involved in surrogacy arrangements; and cultural, legal, and economic contexts. The theoretical contribution of the article is to further the development of a relational justice approach to surrogacy. (shrink)

This study investigated how learner support services at the University of Calabar predict business education students' preparation for online learning. Two specific objectives were established, two research questions were posed, and two null hypotheses were developed and tested at a significant level of .05. Pertinent literature was reviewed. The population consisted of 147 University of Calabar 400-level business education students. This population also formed the sample using a census process. Data were gathered using a structured questionnaire with 40 items that (...) were validated by five specialists from the University of Calabar. Cronbach Alpha statistics were used to establish the questionnaire's reliability, yielding reliability coefficients of 0.88 and 0.85 for the independent sub-variables and dependent variable, respectively. Following the administration of the questionnaire, the data collected was analyzed using linear regression analysis to test the hypotheses. The results show that academic and technological support services strongly predict business education students' preparation for online instruction at the University of Calabar. Based on these findings, the study recommends that lecturers, counsellors, and academic technicians should encourage students to participate in digital education by offering intellectual, emotional, and other support services.

Emotion processing is known to be impaired in psychopathy, but less is known about the cognitive mechanisms that drive this. Our study examined experiencing and suppression of emotion processing in psychopathy. Participants, violent offenders with varying levels of psychopathy, viewed positive and negative images under conditions of passive viewing, experiencing and suppressing. Higher scoring psychopathics were more cardiovascularly responsive when processing negative information than positive, possibly reflecting an anomalously rewarding aspect of processing normally unpleasant material. When required to experience emotional (...) response, by ‘getting into the feeling’ of the emotion conveyed by a negative image, higher factor 1 psychopathic individuals showed reduced responsiveness, suggesting that they were less able to do this. These data, together with the absence of corresponding differences in subjective self-report might be used to inform clinical strategies for normalising emotion processing in psychopathic offenders to improve treatment outcome, and reduce risk amongst this client group.

Successful teamwork doesn't work overnight, what makes teamwork potent is team building. (Plagiarism) According to Abdullah, et. al., (2022) team building training can improve group cohesiveness or the quality of sticking together or unity teamwork more likely to be higher with a significant score difference. This study used mixed methods both qualitative and quantitative data collection, and an analysis method to answer the research method, random sampling is named as such because the data set is chosen via random selection, where (...) every member of the population has an equal probability of being selected (Tao, 2023). The respondents were 100 restaurant employees and 10 managers from the chosen restaurant in Malolos City in Bulacan. The subcategories of team building, including activities, communication, skills, personality, problem-solving, and values, have all received a consensus of strong agreement, with weighted averages falling within the range of 3.26 to 3.44. This level of agreement aligns with the scores for motivation at 3.43 and productivity at 3.38. These values have been calculated by determining the mean, which spans from 3.25 to 4.00. The advantages of team building that is being observed by the managers is to create familiarity and teamwork among the employees, to improve the quality of service and the quality of the food especially the respondents are in the food service sector, development, and training for the employees to achieve the establishments’ goal and lastly rebuilding and build a relationship with one employee to another. However, for the disadvantages, it costs a lot of money to conduct team building in the management. Therefore, the null hypothesis is rejected. Despite the fact that there is a low correlation between teambuilding activities and motivation and employee productivity, there is still a significant relationship between the variables. (shrink)

Jenny Saville is a leading contemporary painter of female nudes. This paper explores her work in light of theories of gender and embodied agency. Recent work on the phenomenology of embodiment draws a distinction between the body image and the body schema. The body image is your representation of your own body, including your visual image of it and your emotional attitudes towards it. The body schema is comprised of your proprioceptive knowledge, your corporeally encoded memories, and your corporeal proficiency (...) with respect to various environments and activities. Saville is concerned with body image issues, and I discuss how she reconfigures representational practices with respect to feminine body images. However, the most exciting potential for feminist analysis of the state of the female nude derives from the concept of the body schema, for this concept endows the human body with subjectivity and agency. My key question, then, is by what pictorial means and to what extent Saville succeeds in representing agentic womanhood. I argue that interpreting Saville’s paintings from the standpoint of the body schema demonstrates the radicality of her remaking of the female nude and the rapport between her imagery and feminist values.

This paper addresses two related topics: 1. The disanalogies between elective cosmetic practices and sex reassignment surgery. Why does it seem necessary for me – an aging professional woman – to ignore the blandishments of hairdressers wielding dyes and dermatologists wielding acids and scalpels? Why does it not seem equally necessary for a transgendered person to repudiate sex reassignment procedures? 2. The role of the body in identity and agency. How do phenomenological insights regarding the constitution of selfhood in relation (...) to the interplay between the body image and corporeal know-how contribute to an account of the agency of transgendered individuals? Studying several paintings by contemporary feminist artist Jenny Saville has advanced my thinking on these topics. Saville’s imagery is an invaluable aid to reflection on these issues because she uses her painterly technique, which critics often dub “virtuoso,” to represent lived human bodies. In her work, viewers encounter representations of subjectivized, agentic corporeity, as distinct from inert, objectified flesh. Moreover, her sympathetic engagement with nonconformist, devalued bodies helps to reconfigure the standard gestalts of the human body that viewers typically carry with them and thus to convert fear and/or disgust into appreciation and understanding. In this paper, I consider three of Saville’s paintings. Plan, Saville’s self-portrait as a nude female whose body has been prepped for liposuction, conveys the pathos of this procedure. Matrix is a nude portrait of self-described “gender variant visual artist” Del LaGrace Volcano. In the words of one critic Saville’s depiction of Volcano’s nude intersexed body “restores beauty to the primitive [female] genital organ.” Passage, another nude portrait of an intersexed individual, is an image of vibrant sexuality despite the presumptively jarring juxtaposition of breasts and a penis. I argue that conceiving the agentic subject as a rational deliberative capability that uses a conjoined body as the instrument of its will makes it impossible to theorize the agency of transgendered people. In contrast, when agentic subjects are understood as embodied subjects and embodiment is understood as a dimension of practical intelligence, the agency of transgendered individuals is intelligible.

"The concluding chapter, penned by C. E. Emmer, both revisits and greatly expands upon disputations within the contested territory of kitsch as term and tool in cultural turf-war arsenals. Focusing on debates surrounding two visual responses to the terrorist attacks on September 11, 2001, Dennis Madalone's 2003 music video for the patriotic anthem 'America We Stand As One' and Jenny Ryan's 'plushie' sculpture, 'Soft 9/11,' Emmer utilizes these debates to reveal the coexisting and competing attitudes towards ostensibly kitschy objects and (...) the contentiousness of deploying kitsch as a term in these debates. The buzzing activity of the internet provides much of the raw material for his arguments. Through his close reading of both the works themselves and the public response to them, Emmer once more focuses attention on the competing and overlapping attitudes towards kitsch and the way in which it and its semantic cousins remain a viable and valuable resource with which to police the borders that surround the artworld. Ultimately, his contribution further grounds a wider premise operative in this collection--namely, that a simple and rigid dichotomy of kitsch and (high) art does not and indeed cannot capture the elusive and mercurial nature of kitsch." --from the editor's introduction.

Semiotics has been making progressively inroads into marketing research over the past thirty years.

This essay explores the role that the aesthetic-nonaesthetic distinction plays in assessing activist art by women and artists of color. First, I shall review one traditional line of philosophical thought and show how it serves as the foundation for three types of reasons typically given for artworks reputed to lack aesthetic value. I develop two of the three reasons by examining recent writings opposed to the aesthetic value of activist art by well-known art critic Donald Kuspit, pointing out his aberrant (...) use of "obscene." Kuspit's examples of activist art--the work of Jenny Holzer, Barbara Kruger, and Adrian Piper--are presented in light of his charges. I then explore Piper's art in depth in order to outline ways of expanding the notion of aesthetic value beyond its traditional confines. Finally, I suggest moving beyond entrenched, traditional patterns of assessment and invite underrepresented voices to contribute to the emerging discussion of the multiplicity of aesthetic values.

MUDANÇAS, REVOLUÇÕES E SUAS IMPLICAÇÕES -/- CHANGES, REVOLUTIONS AND THEIR IMPLICATIONS -/- Emanuel Isaque Cordeiro da Silva – IFPE-BJ, CAP-UFPE e UFRPE - [email protected] / [email protected] e WhatsApp: (82)98143-8399 -/- PREMISSA -/- A mudança social é um tema presente na Sociologia desde o seu início. Seria possível dizer que o surgimento da Sociologia está vinculado à discussão sobre as transformações sociais, ou seja, falar sobre a ciência da sociedade é falar sobre esse tema. Por isso mesmo, abordar o tema da (...) mudança social pressupõe lidar com a questão das resistências às possíveis transformações. Quando uma comunidade ou uma sociedade se depara com mudanças, de origem interna ou externa, há sempre resistência, pois há uma espécie de acomodação ao que já existe. Assim, as relações de poder, por exemplo, podem se modificar, num complexo jogo de resistência contra o poder e desejo de conquistá-lo ou ampliá-lo. Desse modo, confrontos e conflitos compõem o itinerário das mudanças e revoluções sociais. -/- Aqui serão objetos de análise dois grandes tipos de mudanças sociais: aquelas que, por seu caráter universal e multifacetado, afetaram toda a humanidade e aquelas de conotação sociopolítica, que atingiram determinadas sociedades e, depois, tornaram-se referência para outras mudanças. Serão, portanto, abordadas as revoluções agrícola e industrial e as recentes transformações e os episódios mais marcantes das revoluções políticas contemporâneas em todo o mundo. -/- A REVOLUÇÃO AGRÍCOLA -/- Esta revolução transformou radicalmente a forma de produção de alimentos das populações humanas. A expressão “revolução agrícola” foi criada pelo arqueólogo australiano Gordon Childe (1892-1957). Ela também é chamada de “revolução do Neolítico”, pois foi o período em que a humanidade desenvolveu a agricultura e as técnicas de cultivo de alimentos, como também aprendeu a domesticar e criar animais. Isso alterou o processo de obtenção de alimentos, pois as populações deixaram de ser coletoras e caçadoras e passaram, paulatinamente, a ter uma relação diferenciada com animais e plantas. Essas mudanças não ocorreram ao mesmo tempo em todos os lugares. Elas se iniciaram no Oriente Médio (há 9 ou 10 mil anos). Depois, no Egito (9 mil), na Índia (8 mil), na China (7 mil), na Europa (6,5 mil), na África tropical (5 mil) e na América, principalmente no México e no Peru (4,5 mil anos), através do deslocamento de hordas humanas ou movimentos independentes. O processo foi muito longo. Inicialmente, percebeu-se que os grãos que eram coletados para alimentação poderiam ser enterrados, isto é, “semeados”, a fim de produzir novas plantas iguais às que eram coletadas anteriormente. Assim, foi possível produzir trigo, cevada, milho, arroz e tubérculos (vários tipos de batatas); posteriormente, também árvores frutíferas. A partir de então, em consequência da experiência e da observação do que acontecia no meio ambiente, passou-se a selecionar sementes e outras árvores para plantio. Através da experiência prática, desenvolveu-se um conhecimento dos diferentes tipos de solo e de plantas, o que ajudou a aprimorar as técnicas de plantio e colheita, incluindo a observação da melhor época para o desenvolvimento de cada uma das culturas. Determinante para a fixação de grupos humanos (sedentarização) há milhares de anos, a agricultura ainda é a principal atividade de parte expressiva da população mundial. Essa atividade é a eminente na questão de desenvolvimento do Brasil, uma vez que o setor a cada ano emprega mais, a cada ano produz mais e a cada ano supera os índices de lucratividade anteriores, sendo, por fim, o baú do tesouro brasileiro. Voltando para a Revolução, outro elemento essencial desse processo foi a domesticação de animais. Junto com a agricultura, esse foi um passo muito importante para a alteração do modo de vida da humanidade, já que eliminou a necessidade do deslocamento para obtenção da carne e das peles necessárias ao conforto e também do leite dos rebanhos. A domesticação deve ter surgido espontaneamente em vários locais, resultado do processo de aproximação e observação dos animais no decurso das caçadas. O primeiro animal domesticado foi o cão; na sequência, animais para a alimentação e tração, como a cabra, o carneiro, o boi e o cavalo. Paralelamente a essas mudanças, alguns instrumentos foram sendo confeccionados, como a foice, o arado, a roda e outros que eram utilizados para arar a terra e até na colheita: novas tecnologias para um processo revolucionário. Esse processo intenso de subdivisões e deslocamentos provocou uma onda de difusão da agricultura e da atividade pastoril através das migrações. Imagine-se por um momento vivendo em grupos ou fazendo parte de hordas humanas, reproduzindo-se e subdividindo-se, migrando para outros locais, plantando e desenvolvendo a criação de animais em vários lugares, deslocando-se à procura de novos espaços e invadindo territórios de outros grupos, convivendo entre si ou em conflito, aprendendo e ensinando aos grupos com os quais estabeleceram alguma comunicação e submetendo-se ou sendo submetidos pelos habitantes com quem entraram em contato. Esse é apenas um pequeno esboço do que ocorreu nesse processo de transmissão e absorção de novas formas revolucionárias de viver. A grande revolução agrícola (que foi, em essência, a síntese de centenas de revoluções localizadas no tempo e no espaço e marcadas pela diversidade de ações e resultados) foi aquela que alterou de fato e profundamente toda a humanidade. Mas ela continua até hoje, uma vez que as transformações que ocorrem na produção de alimentos não estacionaram e mantêm um processo de mudança contínuo. Entretanto, existem ainda formas de organização social, como a de alguns poucos povos caçadores e coletores, que utilizam a agricultura e a domesticação de animais à moda antiga. -/- A REVOLUÇÃO INDUSTRIAL -/- O que se chama de Revolução Industrial na Europa nos séculos XVIII e XIX não é uma revolução puramente industrial, nem começou repentinamente nesses séculos. Foi um processo lento de transformação que se desenvolveu desde o século XV e atingiu grandes setores da produção, como o mineiro, o metalúrgico e o têxtil. A expansão da produção nesses setores envolveu a invenção de novas técnicas e máquinas, além de uma estrutura (a fábrica) que permitisse a concentração de equipamentos e trabalhadores num só lugar. Situadas quase sempre nas cidades, as fábricas requeriam muita mão de obra. Atraindo as pessoas que deixavam o campo em busca de trabalho, as cidades cresceram vertiginosamente. Transformava-se, assim, a forma de produzir bens e serviços, alterando as formas de viver e revolucionando as relações sociais. Mas isso não aconteceu de maneira uniforme no mundo todo. Para que se tenha ideia da multiplicidade das mudanças trazidas pela urbanização e pela industrialização, a Inglaterra conheceu esses fenômenos típicos da modernidade em torno de 1860; o Brasil, por volta da década de 1930; a China, a partir do final do século XX. A Revolução Industrial começou no setor têxtil, na produção da lã e do algodão, com o uso das máquinas de fiar conhecidas como Spinning Jenny (1764) e Spinning Mule (1789), inventadas, respectivamente, por James Hargreaves e Samuel Crompton. Nessa época, a produção era feita manualmente, com rocas de baixíssimo rendimento. Pode-se dizer que, paralelamente à Revolução Industrial, houve na Europa uma segunda revolução agrícola. Ela teve início com a mudança na estrutura da propriedade rural, quando os proprietários de terras se juntaram a ricos comerciantes das cidades interessados em investir na agricultura e promoveram a introdução de novas técnicas de cultivo, entre as quais a rotação de culturas sem pousio (parcela de terras em repouso), de forma a retirar o máximo proveito das terras; a drenagem de terras pantanosas; o abate de florestas; e a ocupação de terras comunais. No intuito de melhorar a produção, promoveram a seleção das espécies mais produtivas, de sementes e o apuramento dos melhores rebanhos. Além disso, foram introduzidas máquinas e houve melhora nos transportes no espaço agrário. Isso permitiu relativa abundância em produtos agrícolas essenciais (carne, leite e derivados, legumes, tubérculos, cereais etc.), que juntamente com a indústria extrativa do sal, indispensável para a conservação dos alimentos, propiciou a melhoria gradual na dieta alimentar. Essas mudanças e a diminuição crescente da mortalidade propiciaram o que se pode chamar de revolução demográfica. Para se ter uma ideia, na Inglaterra, onde a Revolução teve início, a população em 1750 era de 6,5 milhões; em 1801 passou a 16,3 milhões e, em 1851, somava 27,5 milhões. Isso exigiu um aumento da produção e de matérias-primas vegetais e animais (transformadas nas fábricas). No século XIX, outras transformações ocorreram em face da emergência de novas fontes energéticas (eletricidade e petróleo) e de novos ramos industriais, o que resultou em alteração profunda nos processos produtivos, com a introdução de novas máquinas e equipamentos. Todas essas transformações propiciaram mudanças nas comunicações (telégrafo e telefone), nos meios de transporte (navio e trem a vapor, automóvel) e também em todas as esferas da vida (familiar, educacional, jurídica, governamental etc.). Além disso, provocaram o surgimento de inovações na arte, na literatura e nas ciências. -/- AS REVOLUÇÕES CONTEMPORÂNEAS -/- Há uma grande transformação em curso nas sociedades humanas. Os grandes artífices dessas mudanças cada vez mais radicais são as inovações tecnológicas e os resultados alcançados pela evolução dos processos científicos. É difícil demarcar espaços que estejam imunes a essa era de revoluções múltiplas e de largo alcance: de algum modo, todas as culturas estão imersas nessa nova fase da aldeia global, em que tudo e todos parecem estar condenados à interconexão e às novas realidades na microeletrônica, na genética de laboratório e na nanotecnologia, para citar apenas alguns dos “admiráveis mundos novos”. A microeletrônica revolucionou a escala produtiva de bens e serviços mediante o desenvolvimento de sistemas computacionais. Provocou uma mudança significativa também nos meios de comunicação. O uso de celulares, smartphones, computadores pessoais e portáteis, tablets e outros tantos equipamentos está alterando a forma de as pessoas e organizações públicas e privadas se comunicarem e se estruturarem. Novos componentes eletrônicos produzidos com base na nanotecnologia poderão revolucionar o que hoje conhecemos por computação, permitindo a produção de computadores pessoais com muitos processadores, extremamente rápidos e com enorme capacidade de armazenamento. No futuro, os nanoprocessadores provavelmente estarão presentes na maioria dos objetos que utilizaremos. Por meio da microeletrônica e da nanotecnologia, o nível de desenvolvimento da bioengenharia (ou engenharia genética) beirará a ficção científica. A manipulação genética, com o aprofundamento do conhecimento do DNA humano, de plantas e animais, será ampliada. As pesquisas mais divulgadas nessa área se referem às possibilidades de intervenção no campo da Medicina, como as vinculadas à utilização de células-tronco, à produção de vacinas e medicamentos específicos, à produção sintética de elementos essenciais à saúde humana (como a insulina e a albumina), à análise genética das doenças e à consequente terapia gênica, aos transplantes, ao mapeamento genético dos indivíduos, à formação de bancos de genoma de espécies em extinção, à recuperação de DNA de espécies extintas e até à clonagem de animais. Essas transformações podem gerar, entretanto, novos desafios e suscitar questões atreladas, por exemplo, à privacidade dos indivíduos, ao acesso desigual à tecnologia, aos riscos ambientais (aos seres vivos, incluindo os humanos), às relações sociais e de trabalho, às mudanças de valores e normas sociais e, principalmente, às possibilidades de maior liberdade e igualdade ou maior opressão/controle, além de maior ou menor desigualdade social. A Sociologia, que, como vimos, nasceu na Europa no contexto de grandes transformações, propõe debates sobre essas novas tecnologias e as mudanças sociais provocadas pelo uso delas. São necessários novos olhares, novos conceitos e teorias para dar conta desses elementos que estão afetando a vida humana em todos os sentidos. A utilização de novos saberes e tecnologias alterará a pesquisa em todas as ciências, permitindo mais aprofundamento, através de novos equipamentos, com modificações sensíveis nos modos de conhecer o mundo. A aplicação e o desenvolvimento científicos exercerão impacto na maioria das indústrias existentes, em áreas como as de sistemas de construção, transportes, comunicações, maquinário agrícola, e, é claro, na prestação de serviços. Será possível fabricar materiais cem vezes mais resistentes que o aço, carros cuja lataria não estará sujeita a riscos, espelhos antiofuscantes, aviões mais leves, jornais eletrônicos de plástico semelhante ao papel, tintas que mudam de cor etc. No cotidiano, roupas que não amassam ou que não cheiram mesmo depois de absorver muito suor poderão ser compradas em supermercados; do mesmo modo, tecidos que controlam a temperatura do corpo, adaptando-o confortavelmente à temperatura do ar, serão vendidos a preços acessíveis em toda parte, ao lado de vestimentas que auxiliam no emagrecimento e em diversas atividades orientadas por médicos e profissionais de saúde e esporte. O futuro, então, logo trará roupas impermeáveis, inodoras e que não mancham, as chamadas roupas interativas. Esses são exemplos simples do que já existe, mas ainda não em escala industrial para consumo massivo. A presença de robôs no processo produtivo já é uma realidade insofismável e pode-se prever que em pouco tempo eles farão serviços domésticos e outras várias atividades que hoje são desenvolvidas por pessoas de carne, osso e alma. Veículos autônomos, ou os automóveis que andam sozinhos, estão sendo desenvolvidos e alguns já são utilizados para a alegria e o espanto de muita gente. Na área ambiental, a revolução tecnológica poderá ocorrer em muitos campos. Ganharão muita visibilidade o uso de materiais alternativos e a utilização do que hoje chamamos de resíduos industriais ou domésticos na fabricação de mercadorias. Todos esses resíduos, que hoje são descartados, inclusive os chamados não recicláveis, podem passar a ser matérias-primas para diferentes setores da economia. A máxima de Lavoisier (1743-1794) seria então plenamente consagrada: Na natureza nada se cria, nada se perde, tudo se transforma. Nem tudo são flores, entretanto. Acesso desigual aos frutos dessas mudanças; prejuízos ao meio ambiente (riscos aos seres vivos, incluindo os humanos), às relações sociais e de trabalho, aos valores e normas sociais e, principalmente, às possibilidades de maior liberdade e igualdade ou mais opressão e controle, além de maiores ou menores desigualdades sociais. Um conjunto de situações novas para as quais ainda não se tem respostas pode surgir da expansão tecnológica e do desenvolvimento da ciência. Assim como a energia atômica trouxe benefícios extraordinários e malefícios estarrecedores à humanidade, novas tecnologias e inovadores processos científicos poderão trazer grandes soluções e reviravoltas nas formas de ser e de viver, bem como enormes e imprevisíveis prejuízos e destruições. -/- BREVE CONCLUSÃO -/- As revoluções do passado e do presente se estenderão ainda por muito tempo, uma vez que são expressões da atividade humana, a qual transforma o meio e é por ele transformada. Não há transformações que não retenham algo do passado e, ao mesmo tempo, delineiem alguns traços do futuro, pois as mudanças, por mais radicais que sejam, sempre conservam algo. Além disso elas não ocorrem em todos os lugares nem atingem a todos da mesma forma, deixando abertas as portas da história. Essa imprevisibilidade da ação humana, calcada no tempo anterior e orientada para os dias posteriores, dá graça e mistério à existência, tornando a vida em sociedade um desafio de conquistas fabulosas e um palco de derrotas lampejantes. -/- REFERENCIAL TEÓRICO -/- ALMOND, M.; BATISTA, G.
