' National Indigenous People Foundation ' ) or FUNAI is a Brazilian governmental protection agency for Amerindian interests and their culture. In 1910, the Indian Protection Service (Serviço de Proteção ao Índio), or the SPI, was founded under

There are documented accounts of smallpox being used as a biological weapon by some Brazilian villagers seeking to eliminate nearby Amerindian tribes, not always aggressively. One notable instance, according to anthropologist Mércio Pereira Gomes, occurred in Caxias, in southern Maranhão. Local farmers, desiring more land for their cattle farms, gave clothing from sick villagers (which would normally have been burned to prevent further infection) to

Silva was also nominated but not confirmed as an aide to Nabhan Garcia , a senior agriculture ministry official and president of an agribusiness lobby. According to The Guardian , former FUNAI president Gen Franklimberg de Freitas has said that Garcia "froths hate" for indigenous people and that he sees FUNAI as "an obstacle to national development". In April 2020, FUNAI authorized
452-562: A government agency is important for Indian populations, but this also means that FUNAI, as a part of the government, has authority to act contrary to the welfare of the Indians. For example, the Indian Statute permitted mining on indigenous lands; a decree in 1983 restricted mining to minerals necessary only for national defense and security, but still allowed private companies to have licenses and use indigenous labor if necessary. In

The analysis supported a scenario in which European colonization caused a substantial loss of pre-Columbian lineages." Linguistic studies have supported genetic findings, revealing ancient patterns between the languages spoken in Siberia and those in

He stated that many well-founded beliefs are not scientific and, conversely, many scientific conjectures are not well-founded. He also stated that demarcation criteria were historically used as machines de guerre in polemical disputes between "scientists" and "pseudo-scientists". Advancing a number of examples from everyday practice of football and carpentry and non-scientific scholarship such as literary criticism and philosophy, he considered
791-938: A ministerial position in the Brazilian government, when she was appointed as a minister. Indigenous peoples in Brazil The Indigenous peoples in Brazil are the peoples who lived in Brazil before European contact around 1500 and their descendants. Indigenous peoples once comprised an estimated 2,000 district tribes and nations inhabiting what is now Brazil. The 2010 Brazil census recorded 305 ethnic groups of Indigenous people who spoke 274 Indigenous languages ; however, almost 77% speak Portuguese. Historically, many Indigenous peoples of Brazil were semi- nomadic and combined hunting, fishing, and gathering with migratory agriculture. Many tribes faced extinction as

Medical writers of the Hippocratic tradition maintained that their discussions were based on demonstration of logical necessity, a theme developed by Aristotle in his Posterior Analytics . One element of this polemic for science was an insistence on a clear and unequivocal presentation of arguments, rejecting

If an astronomer's prediction failed, then this was a puzzle that he could hope to solve for instance with more measurements or with adjustments of the theory. In contrast, the astrologer had no such puzzles since in that discipline "particular failures did not give rise to research puzzles, for no man, however skilled, could make use of them in a constructive attempt to revise
1130-685: A result of European settlement, and many others were assimilated into the general Brazilian population . The Indigenous population was decimated by European diseases, declining from a pre-Columbian high of 2 million to 3 million to approximately 300,000 by 1997, distributed among 200 tribes. According to the 2022 IBGE census, 1,693,535 Brazilians classified themselves as Indigenous, and the census recorded 274 Indigenous languages spoken by 304 different Indigenous ethnic groups. On 18 January 2007, Fundação Nacional do Índio reported 67 remaining uncontacted tribes in Brazil, up from 40 known in 2005. With this increase, Brazil surpassed New Guinea , becoming
1243-834: A result, reservation lands suffered massive deforestation and flooding. The public works projects attracted very few migrants, but those who did arrive—largely poor settlers—brought new diseases that further devastated the Amerindian population. The 1988 Brazilian Constitution recognizes the right of Indigenous peoples to pursue their traditional ways of life and to the permanent and exclusive possession of their "traditional lands," which are demarcated as Indigenous Territories . Additionally, Indigenous peoples are legally recognized as one of several " traditional peoples ". In practice, however, Brazil's Indigenous people still face significant threats and challenges to their continued existence and cultural heritage. The process of land demarcation

For the next two decades, Brazil was ruled by a series of generals. The country's mantra was "Brazil, the Country of the Future," which the military government used to justify a massive push into the Amazon to exploit its resources, aiming to transform Brazil into one of

We teach the rest of them so much science so that they will appreciate what it means to be scientific – and, hopefully, become scientifically literate and apply some of those lessons in their lives. For such students, the myth of a bright line of demarcation is essential. Discussions of the demarcation problem concern the rhetoric of science and promote critical thinking , which
1582-465: A sociological one". Kuhn's work largely called into question Popper's demarcation, and emphasized the human, subjective quality of scientific change. Paul Feyerabend was concerned that the very question of demarcation was insidious: science itself had no need of a demarcation criterion, but instead some philosophers were seeking to justify a special position of authority from which science could dominate public discourse. Feyerabend argued that science
1695-519: A statement's scientific or non-scientific status does not change over time. This has been summarized as a statement being falsifiable "if and only if it logically contradicts some (empirical) sentence that describes a logically possible event that it would be logically possible to observe". Thomas Kuhn , an American historian and philosopher of science, is often associated with what has been termed postpositivism or postempiricism . In his 1962 book The Structure of Scientific Revolutions , Kuhn divided
1808-673: A task attributed to FUNAI by the constitution – to the Agriculture Ministry. Several months later, Brazil's National Congress overturned these changes. According to Al Jazeera , in February 2019, several indigenous organisations reported to the Inter-American Commission on Human Rights on violence exerted against indigenous communities including homicides, stonings, deforesting, threats and arson. In July 2019, Bolsonaro appointed Marcelo Xavier da Silva,
1921-599: A third migrant wave. The initial settlement of the Americas was followed by a rapid expansion southward along the coast, with limited gene flow later, especially in South America . An exception to this is the Chibcha speakers, whose ancestry includes contributions from both North and South America. Another study, focused on mitochondrial DNA ( mtDNA ), which is inherited only through the maternal line, revealed that
2034-543: Is a division within FUNAI to handle dealings with isolated indigenous tribes . Article 231 of the 1988 Constitution expresses indigenous peoples' rights to preserve their culture, traditions, and customs; since contact with mainstream society could jeopardize isolated tribes' culture, FUNAI undertakes efforts to maintain these tribes' isolation. The CGIIRC division is responsible for protecting areas with known isolated tribes from outside contact, since outside contact could spread disease within indigenous communities. The department
2147-422: Is because even metaphysicians' first premises will necessarily begin with observations made through sense-perception. Ayer implied that the demarcation occurs when statements become "factually significant". To be "factually significant", a statement must be verifiable. In order to be verifiable, the statement must be verifiable in the observable world, or facts that can be induced from "derived experience". This
2260-436: Is important for democracy. For example, Gordin stated: "Demarcation remains essential for the enormously high political stakes of climate-change denial and other anti-regulatory fringe doctrines". Philosopher Herbert Keuth [ de ] noted: Perhaps the most important function of the demarcation between science and nonscience is to refuse political and religious authorities the right to pass binding judgments on
2373-437: Is inseparable from the larger body of human thought and inquiry. Paul R. Thagard proposed another set of principles to try to overcome these difficulties, and argued that it is important for society to find a way of doing so. According to Thagard's method, a theory is not scientific if it satisfies two conditions: Thagard specified that sometimes theories will spend some time as merely "unpromising" before they truly deserve

#17328019392482486-459: Is normal science, in which Sir Karl 's sort of testing does not occur, rather than extraordinary science which most nearly distinguishes science from other enterprises. If a demarcation criterion exists (we must not, I think, seek a sharp or decisive one), it may lie just in that part of science which Sir Karl ignores. Kuhn's view of demarcation is most clearly expressed in his comparison of astronomy with astrology. Since antiquity, astronomy has been

He argued that, within the history of scientific practice, no rule or method can be found that has not been violated or circumvented at some point in order to advance scientific knowledge. Both Imre Lakatos and Feyerabend suggest that science is not an autonomous form of reasoning, but
2712-601: Is present in 12 regions of Brazil's Amazon region, and almost all of Brazil's known uncontacted tribes reside within already demarcated lands. FUNAI has records of about 107 isolated Indians' presence. The Brazilian Constitution of 1988 recognized Indians' rights to practice their customs without pressure to assimilate or integrate into mainstream Brazilian society. Article 231 also defines Indians' rights to their lands, and outlines FUNAI's responsibility to demarcate those lands. The article also provides that mining and other energy resources on indigenous lands are only allowed with
2825-558: Is referred to as the "verifiability" criterion. This distinction between science, which in the opinion of the Vienna Circle possessed empirically verifiable statements, and what they pejoratively termed "metaphysics", which lacked such statements, can be considered as representing another aspect of the demarcation problem. Logical positivism is often discussed in the context of the demarcation between science and non-science or pseudoscience. However, "The verificationist proposals had
2938-586: Is scornful of evidence. The pseudoscientist reaches a preferred conclusion in advance, then selects evidence, often removed from any relevant context, to lend supposed support for their conclusions. Often the preconceived conclusion is one that justifies some closely held identity or ideology. Contradictory evidence is waved away or ignored, and as a last resort, one can always claim conspiracy to keep pseudoscientific ideas suppressed. Concerning science education , Michael D. Gordin wrote: Every student in public or private schools takes several years of science, but only
3051-645: Is slow, often involving protracted legal battles, and FUNAI lacks sufficient resources to enforce legal protections on Indigenous lands. Since the 1980s, exploitation of the Amazon Rainforest for mining, logging, and cattle ranching had surged, which poses a severe threat to the region's Indigenous population. Settlers illegally encroaching on Indigenous land continue to destroy the environment necessary for traditional ways of life, provoke violent confrontations, and spread disease. Demarcation problem In philosophy of science and epistemology ,
3164-476: Is untestable but from claims that it has been tested and failed the tests. Popper argued that the Humean induction problem shows that there is no way to make meaningful universal statements on the basis of any number of empirical observations. Therefore, empirical statements are no more "verifiable" than metaphysical statements. This creates a problem for the demarcation the positivists wanted to define between

The Portuguese arrived at the end of a long pre-colonial conflict between the Tupis and Tapuias, which had led to the defeat and expulsion of the Tapuias from most coastal areas. Although

The second and third migratory waves from Siberia, which are thought to have led to the Athabaskan , Aleut , Inuit , and Yupik people , apparently did not reach farther than the southern United States and Canada , respectively. An analysis of Amerindian Y-chromosome DNA reveals specific clustering within much of the South American population. The micro-satellite diversity and distributions of Y-chromosome lineages specific to South America suggest that certain Amerindian populations have been isolated since

The names by which different Tupi tribes were recorded by Portuguese and French authors in the 16th century are poorly understood. Most do not seem to be proper names but rather descriptions of relationships, usually familial—e.g., Tupi means "first father," Tupinambá means "relatives of

The humid climate and acidic soil have destroyed almost all traces of their material culture, including wood and bones . Therefore, what is known about the region's history before 1500 has been inferred and reconstructed from limited archaeological evidence, such as ceramics and stone arrowheads . The most conspicuous remains of these societies are vast mounds of discarded shellfish , known as sambaquis , found at some coastal sites that were continuously inhabited for more than 5,000 years. Additionally, substantial "black earth" ( terra preta ) deposits in several places along

At other times, they sided with Portugal against rival tribes. During this period, a German soldier named Hans Staden was captured by the Tupinambá and later released. He documented his experiences in his famous book Warhaftige Historia und Beschreibung eyner Landtschafft der Wilden Nacketen, Grimmigen Menschfresser-Leuthen in der Newenwelt America gelegen (1557), which translates to True Story and Description of

It also examines the boundaries between science, pseudoscience and other products of human activity, like art and literature and beliefs . The debate continues after more than two millennia of dialogue among philosophers of science and scientists in various fields. The debate has consequences for what can be termed "scientific" in topics such as education and public policy . An early attempt at demarcation can be seen in

The "grandsons" (Temiminó) might represent a splinter group, while the "side-neighbors" (Tupiniquim) could denote recent arrivals still establishing their presence. However, by 1870, the Tupi tribes' population had declined to 250,000 Indigenous people, and by 1890, it had diminished to approximately 100,000. When

In 1967, the officials were accused of sexual perversion, abuse, and the massacre of entire tribes by introducing diseases and pesticides, leading to an international outcry for the disbandment of SPI. Following this disbandment, FUNAI was created to take over SPI's responsibilities and remedy the damages caused by corruption. FUNAI

In Brazil, most native tribes living in the land by 1500 are thought to be descended from the first wave of Siberian migrants, who are believed to have crossed the Bering Land Bridge at the end of the last Ice Age, between 13,000 and 17,000 years ago. This initial migration would have taken some time to reach present-day Brazil, likely entering

However, an ancient signal of shared ancestry with the Indigenous peoples of Australia and Melanesia was detected among the Native populations of the Amazon region . This migration from Siberia is estimated to have occurred around 23,000 years ago. Brazilian native peoples, unlike those in Mesoamerica and

Jesuit priests arrived with the first Governor General as clerical assistants to the colonists, with the intention of converting the Indigenous people to Catholicism . They argued that the Indigenous people should be regarded as human and succeeded in obtaining a Papal bull , Sublimis Deus , which declared that, regardless of their beliefs, they should be recognized as fully rational human beings with rights to freedom and private property, and thus should not be enslaved.

In the mid-1770s, the fragile coexistence between the Indigenous peoples and the colonists was once again threatened. Due to a complex diplomatic situation involving Portugal, Spain, and the Vatican , the Jesuits were expelled from Brazil, and their missions were confiscated and sold. A number of wars broke out between various tribes, such as

In "Histoire des découvertes et conquêtes des Portugais dans le Nouveau Monde," Lafitau described the natives as people who wore no clothing but painted their entire bodies red. Their ears, noses, lips, and cheeks were pierced. The men would shave the front, top of the head, and over the ears, while women typically wore their hair loose or in braids. Both men and women accessorized with noisy porcelain collars and bracelets, feathers, and dried fruits. Lafitau also described

FUNAI identified almost 1.8 million hectares of these lands to be demarcated in 1977, but opposition from farmers and mining companies in the region prevented the completion of its demarcation. After Decree 1775, the claims against the Raposa/Serra do Sol regions were backed by the Roraima state government, which supported breaking up

President Luiz Inácio Lula da Silva's government approved 81 applications for demarcation, but Dilma Rousseff's government approved only 11 territories from 2011 to 2015. The former Brazilian president Jair Bolsonaro has expressed his determination to increase

The same year, the government established the Fundação Nacional do Índio (National Indian Foundation), known as FUNAI, which is responsible for protecting the interests, cultures, and rights of Indigenous peoples in Brazil. Some tribes have become significantly integrated into Brazilian society. The unacculturated tribes that have been contacted by FUNAI are supposed to be protected and accommodated within Brazilian society to varying degrees. By 1987, it

To be scientific, he said, one must deal with causes, one must use logical demonstration, and one must identify
8475-436: The empirical and the metaphysical. By their very own "verifiability criterion", Popper argued, the empirical is subsumed into the metaphysical, and the demarcation between the two becomes non-existent. In Popper's later work, he stated that falsifiability is both a necessary and sufficient criterion for demarcation. He described falsifiability as a property of "the logical structure of sentences and classes of sentences", so that
8588-463: The first evidence of a complex society on Marajó. Further evidence of mound building suggests that well-populated, complex, and sophisticated settlements developed on the island, as only such settlements were believed capable of undertaking extensive projects like major earthworks. The extent, level of complexity, and resource interactions of the Marajoara culture have been subjects of dispute. In
8701-419: The future. His definition is a practical one, which generally seeks to distinguish pseudoscience as areas of inquiry which are stagnant and without active scientific investigation. Many historians of science are concerned with the development of science from its primitive origins; consequently they define science in sufficiently broad terms to include early forms of natural knowledge. In the article on science in
8814-551: The highway directly led to deforestation along the affected parts of the Amazon. Sydney Possuelo was one of the sertanistas/explorers sent to find and relocate the tribes living along the path of the highway. Possuelo and other sertanistas were disturbed by the number of indigenous deaths their contact caused, and met in 1987 to try to stop it. Possuelo's efforts greatly influenced FUNAI's change in policy from "pacification" and integration to preservation. The Central Department for Isolated Indians and Recently Contacted Indians (CGIIRC)
8927-570: The imagery, analogy, and myth of the old wisdom. Some of their claimed naturalistic explanations of phenomena have been found to be quite fanciful, with little reliance on actual observations. Cicero 's De Divinatione implicitly used five criteria of scientific demarcation that are also used by modern philosophers of science. Logical positivism , formulated during the 1920s, is the idea that only statements about matters of fact or logical relations between concepts are meaningful. All other statements lack sense and are labelled " metaphysics " (see
9040-538: The initial colonization of the region. According to a 2012 autosomal DNA genetic study, Native Americans descend from at least three main migrant waves from Siberia. Most of their ancestry traces back to a single ancestral population, referred to as the 'First Americans'. However, Inuit-speaking populations from the Arctic inherited nearly half of their ancestry from a second Siberian migrant wave, while Na-dene speakers inherited about one-tenth of their ancestry from
9153-509: The interior (notably the upper reaches of the Xingu , Teles Pires , and Juruena Rivers , roughly corresponding to modern Mato Grosso state) were the original pre-migration Tupi-Guarani homelands. In addition to the Tupi and Tapuia, two other Indigenous mega-groups were commonly identified in the interior: the Caribs , who inhabited much of what is now northwestern Brazil, including both shores of
9266-461: The interior to claim territory for the Portuguese crown and to search for gold and precious stones . Intending to profit from the sugar trade , the Portuguese decided to cultivate sugar cane in Brazil and to use Indigenous slaves as the workforce, following the example of the Spanish colonies. However, capturing Indigenous people proved difficult. They were soon afflicted by diseases brought by
9379-447: The large-scale agriculture needed to support large populations and complex social formations, such as chiefdoms . The Xingu peoples built large settlements connected by roads and bridges, often featuring moats. Their development peaked between 1200 CE and 1600 CE, with their population reaching into the tens of thousands. On the eve of the Portuguese arrival in 1500, the coastal areas of Brazil were dominated by two major groups:
9492-659: The leadership of Brazilian Marshal Candido Rondon . Rondon created the foundation's motto: "Die if necessary, but never kill." Drawing from his Positivism , Rondon led the SPI with the belief that the native Indians should be allowed to develop at their own pace. With state assistance and protection, Indians would eventually integrate into modern society. The SPI then began its mission to "pacify" Indian communities by setting up posts in their territories to foster communication and protection. Efforts were initially met by opposition and hostility from Indian groups; there were reports of SPI agents being attacked and shot by arrows. During
9605-492: The leading economies of the world. Construction began on a transcontinental highway across the Amazon basin, designed to encourage migration to the region and facilitate trade. Funded by the World Bank , thousands of square miles of forest were cleared without regard for reservation status. Following the highway projects, giant hydroelectric projects were initiated, and vast areas of forest were cleared for cattle ranching. As
9718-411: The lips. Researchers believe this wear was caused by using teeth to peel and shred abrasive plants . The Marajoara culture flourished on Marajó island at the mouth of the Amazon River . Archaeologists have uncovered sophisticated pottery in their excavations on the island. These pieces are large, elaborately painted, and incised with representations of plants and animals. This discovery provided
9831-429: The maternal ancestry of the Indigenous peoples of the Americas traces back to a few founding lineages from Siberia, likely arriving via the Bering Strait . According to this study, the ancestors of Native Americans likely remained near the Bering Strait for a time before rapidly spreading throughout the Americas and eventually reaching South America . A 2016 study on mtDNA lineages found that "a small population entered
9944-516: The middle of the 16th century, Jesuit priests, at the behest of Portugal's monarchy, had established missions throughout the country's colonies. They aimed to Europeanize and convert the Indigenous populations to Catholicism. Some historians argue that the Jesuits provided a period of relative stability for the Amerindians and opposed using them for slave labor. However, the Jesuits also contributed to European imperialism. Many historians view Jesuit involvement as an ethnocide of Indigenous culture, where
10057-404: The mound Teso dos Bichos. She concluded that the society that constructed the mounds originated on the island itself. The pre-Columbian culture of Marajó may have developed social stratification and supported a population as large as 100,000 people. The Native Americans of the Amazon rainforest may have used their method of developing and working in terra preta to make the land suitable for
10170-449: The other, I call the problem of demarcation ." Falsifiability is the demarcation criterion proposed by Popper as opposed to verificationism: "statements or systems of statements, in order to be ranked as scientific, must be capable of conflicting with possible, or conceivable observations." Popper rejected solutions to the problem of demarcation that are grounded in inductive reasoning , and so rejected logical-positivist responses to
10283-429: The philosophical concern to establish a demarcation between science and non-science becomes "problematic, if not futile". Larry Laudan concluded, after examining various historical attempts to establish a demarcation criterion, that "philosophy has failed to deliver the goods" in its attempts to distinguish science from non-science—to distinguish science from pseudoscience. None of the past attempts would be accepted by
10396-417: The plantations. When the Amerindians proved to be a difficult labor force, peasants from surrounding areas were brought in. This created ongoing tension between the Indigenous population and the new arrivals, as the Amerindians felt their lands were being invaded in the pursuit of wealth. In the 20th century, the Brazilian government adopted a more humanitarian approach and began offering official protection to
10509-458: The problem of demarcation. He argued that logical-positivists want to create a demarcation between the metaphysical and the empirical because they believe that empirical claims are meaningful and metaphysical ones are not. Unlike the Vienna Circle, Popper stated that his proposal was not a criterion of "meaningfulness". Popper's demarcation criterion has been criticized both for excluding legitimate science ... and for giving some pseudosciences
10622-463: The process of being demarcated. FUNAI followed procedure and submitted its official opinion to the Ministry of Justice, rejecting the appeals that were brought against the indigenous lands. Justice Nelson Jobim sided with FUNAI on all except eight territories, ordering further investigation. One of these territories was the Raposa/Serra do Sol region in the northern state of Roraima , home to
10735-436: The process of doing science into two different endeavors, which he termed normal science and extraordinary science (sometimes known as "revolutionary science"), the latter of which introduces a new " paradigm " that solves new problems while continuing to provide solutions to the problems solved by the preceding paradigm. Finally, and this is for now my main point, a careful look at the scientific enterprise suggests that it
10848-543: The pursuit of Amazonian brazilwood for its prized red dye convinced the colonists that they needed to "civilize" the natives (originally, the Portuguese named Brazil Terra de Santa Cruz , but it later acquired its current name (see List of meanings of countries' names ) from the brazilwood ). However, like the Spanish in North America, the Portuguese brought diseases to which many Amerindians had no immunity. Measles , smallpox , tuberculosis , and influenza caused
10961-472: The question of whether a belief is well-founded or not to be more practically and philosophically significant than whether it is scientific or not. In his judgment, the demarcation between science and non-science was a pseudo-problem that would best be replaced by examining the distinction between reliable and unreliable knowledge, without bothering to ask whether that knowledge is scientific or not. He would consign phrases like "pseudo-science" or "unscientific" to
11074-564: The registration and sale of land on unratified or unregistered indigenous territories. This could affect 237 reserves in 24 states. However, in June 2020 the state attorney general of Mato Grosso put in a bid for annulment. He called the authorization a dereliction of FUNAI's own mission. In his first act of government, President Luiz Inácio Lula da Silva issued the Provisional Measure No. 1,154, of 1 January 2023, which created
11187-563: The rhetoric of politicians or sociologists. Others have disagreed with Laudan. Sebastian Lutz, for example, argued that demarcation does not have to be a single necessary and sufficient condition as Laudan implied. Rather, Laudan's reasoning at most establishes that there has to be one necessary criterion and one possibly different sufficient criterion. Various typologies or taxonomies of sciences versus nonsciences, and reliable knowledge versus illusory knowledge, have been proposed. Ian Hacking , Massimo Pigliucci , and others have noted that
11300-420: The ritualistic nature of their cannibalism practices and highlighted the important role of women in the household. Before the arrival of Europeans, the territory of present-day Brazil had an estimated population of between 1 and 11.25 million inhabitants. During the first 100 years of contact, the Amerindian population was reduced by 90%. This drastic decline was primarily due to diseases and illnesses brought by
11413-424: The schools. Although this is not a plea that chemistry teachers should at once introduce the study of proteins into their curricula, it is a suggestion that they should at least inform themselves and become prepared to answer questions and counteract the effects of misinformation . The demarcation problem has been compared to the problem of differentiating fake news from real news, which became prominent during
11526-413: The sciences generally conform to Ludwig Wittgenstein 's concept of family resemblances . Other critics have argued for multiple demarcation criteria, some suggesting that there should be one set of criteria for the natural sciences, another set of criteria for the social sciences, and claims involving the supernatural could have a set of pseudoscientific criteria. Anthropologist Sean M. Rafferty of
11639-483: The status of being scientific ... According to Larry Laudan (1983, 121), it "has the untoward consequence of countenancing as 'scientific' every crank claim which makes ascertainably false assertions". Astrology, rightly taken by Popper as an unusually clear example of a pseudoscience, has in fact been tested and thoroughly refuted ... Similarly, the major threats to the scientific status of psychoanalysis, another of his major targets, do not come from claims that it
11752-472: The title of pseudoscience. He cited astrology as an example: it was stagnant compared to advances in physics during the 17th century, and only later became "pseudoscience" in the advent of alternative explanations provided by psychology during the 19th century. Thagard also stated that his criteria should not be interpreted so narrowly as to allow willful ignorance of alternative explanations, or so broadly as to discount our modern science compared to science of
11865-407: The truth of certain statements of fact. Concern for informed human nutrition resulted in the following note in 1942: If our boys and girls are to be exposed to the superficial and frequently ill-informed statements about science and medicine made over the radio and in the daily press, it is desirable, if not necessary, that some corrective in the form of accurate factual information be provided in
11978-532: The undertaking". A similar definition appeared more recently in David Pingree 's study of early science: "Science is a systematic explanation of perceived or imaginary phenomena, or else is based on such an explanation. Mathematics finds a place in science only as one of the symbolical languages in which scientific explanations may be expressed." These definitions tend to emphasize the subject matter of science rather than its method and from these perspectives,
12091-410: The universals which 'inhere' in the particulars of sense. But above all, to have science one must have apodictic certainty . It is the last feature which, for Aristotle, most clearly distinguished the scientific way of knowing. G. E. R. Lloyd noted that there was a sense in which the groups engaged in various forms of inquiry into nature attempt to "legitimate their own positions", laying "claim to
12204-468: The verifiability theory of meaning also known as verificationism ). According to A. J. Ayer , metaphysicians make statements which claim to have "knowledge of a reality which [transcends] the phenomenal world". Ayer, a member of the Vienna Circle and a noted English logical-positivist, argued that making any statements about the world beyond one's immediate sense-perception is impossible. This
12317-418: The ways that commercial interests could contest the demarcation of lands. Individuals or companies were allowed from the beginning of the demarcation process until 90 days after FUNAI issued their report to submit an appeal showing that the contested lands do not meet the qualifications of indigenous lands as stated in the constitution. The government claimed that allowing people to contest indigenous lands during
12430-458: Was appalled by the treatment of the Indigenous people by settlers and developers, and he became their lifelong friend and protector. Rondon, who died in 1958, is considered a national hero in Brazil. The Brazilian state of Rondônia is named in his honor. After Rondon's pioneering work, the SPI was handed over to bureaucrats and military officers, and its effectiveness declined after 1957. The new officials did not share Rondon's deep commitment to
12543-546: Was created by Law No. 5,371, under jurisdiction of the Ministry of Justice and headquartered in Brasilia . On 19 December 1973, Law No. 6001 officially placed Indians under the protection of FUNAI through the Indian Statute. The Indian Statute, while aiming to demarcate all Indian lands by 1978, also had the main goal to integrate Indians into society as soon as possible, so that the Amazon and its people could start contributing economically to Brazilian society. Protection from
12656-405: Was recognized that unnecessary contact with these tribes was causing illness and social disintegration. Uncontacted tribes are now meant to be shielded from intrusion and interference in their lifestyle and territory. However, the exploitation of rubber and other Amazonian natural resources has led to a new cycle of invasion, expulsion, massacres, and death, which continues to this day. In 1964,
12769-436: Was to end in the subsequent years. The Portuguese colonists , all males, began to have children with female Amerindians, creating a new generation of mixed-race people who spoke Amerindian languages, including a Tupi language called Nheengatu . The children of these Portuguese men and Amerindian women soon formed the majority of the population. Groups of fierce explorers organized expeditions known as " bandeiras " (flags) into
