[ { "plaintext": "Anarchism is a political philosophy and movement that is skeptical of all justifications for authority and seeks to abolish the institutions they claim maintain unnecessary coercion and hierarchy, typically including, though not necessarily limited to, the state and capitalism. Anarchism advocates for the replacement of the state with stateless societies or other forms of free associations.

In dreams, sensation is still involved, but in an altered manner.

When a person perceives a stimulus and the stimulus is no longer the focus of their attention, it leaves an impression. When the body is awake and the senses are functioning properly, a person constantly encounters new stimuli to sense and so the impressions of previously perceived stimuli are ignored. However, during sleep the impressions made throughout the day are noticed as there are no new distracting sensory experiences. So, dreams result from these lasting impressions. Since impressions are all that are left and not the exact stimuli, dreams do not resemble the actual waking experience. During sleep, a person is in an altered state of mind. Aristotle compares a sleeping person to a person who is overtaken by strong feelings toward a stimulus. For example, a person who has a strong infatuation with someone may begin to think they see that person everywhere because they are so overtaken by their feelings. Since a person sleeping is in a suggestible state and unable to make judgements, they become easily deceived by what appears in their dreams, like the infatuated person.

Some definitions specify a self-sacrificial nature to altruism and a lack of external rewards for altruistic behaviors.

The social exchange theory postulates that altruism only exists when benefits to the self outweigh costs to the self. Daniel Batson is a psychologist who examined this question and argues against the social exchange theory. He identified four major motives: to ultimately benefit the self (egoism), to ultimately benefit the other person (altruism), to benefit a group (collectivism), or to uphold a moral principle (principlism). Altruism that ultimately serves selfish gains is thus differentiated from selfless altruism, but the general conclusion has been that empathy-induced altruism can be genuinely selfless. The empathy-altruism hypothesis basically states that psychological altruism does exist and is evoked by the empathic desire to help someone who is suffering. Feelings of empathic concern are contrasted with feelings of personal distress, which compel people to reduce their own unpleasant emotions and increase their own positive ones through helping someone in need. Empathy is thus not selfless, since altruism works either as the way to avoid those negative, unpleasant feelings and have positive, pleasant feelings triggered by others' need for help, or as the way to incentive the gain of social reward or through fear to avoid social punishment by helping. People with empathic concern help others in distress even when exposure to the situation could be easily avoided, whereas those lacking in empathic concern avoid helping unless it is difficult or impossible to avoid exposure to another's suffering.

In 2012, the Pennsylvania State University Press agreed to take over publication of The Journal of Ayn Rand Studies, and the University of Pittsburgh Press launched an \"Ayn Rand Society Philosophical Studies\" series based on the Society's proceedings. The Fall 2012 update to the entry about Rand in the Stanford Encyclopedia of Philosophy said that \"only a few professional philosophers have taken her work seriously\".

Greenberg refuted Meinhof's linguistic theories and rejected the use of racial and social evidence. In dismissing the notion of a separate \"Nilo-Hamitic\" language category, in particular, Greenberg was \"returning to a view widely held a half-century earlier\". He consequently rejoined Meinhof's so-called Nilo-Hamitic languages with their appropriate Nilotic siblings.

Bituminised radioactive waste containing highly radiotoxic alpha-emitting transuranic elements from nuclear reprocessing plants have been produced at industrial scale in France, Belgium and Japan, but this type of waste conditioning has been abandoned because operational safety issues (risks of fire, as occurred in a bituminisation plant at Tokai Works in Japan) and long-term stability problems related to their geological disposal in deep rock formations. One of the main problems is the swelling of asphalt exposed to radiation and to water. Asphalt swelling is first induced by radiation because of the presence of hydrogen gas bubbles generated by alpha and gamma radiolysis. A second mechanism is the matrix swelling when the encapsulated hygroscopic salts exposed to water or moisture start to rehydrate and to dissolve. The high concentration of salt in the pore solution inside the bituminised matrix is then responsible for osmotic effects inside the bituminised matrix. The water moves in the direction of the concentrated salts, the asphalt acting as a semi-permeable membrane. This also causes the matrix to swell. The swelling pressure due to osmotic effect under constant volume can be as high as 200 bar. If not properly managed, this high pressure can cause fractures in the near field of a disposal gallery of bituminised medium-level waste. When the bituminised matrix has been altered by swelling, encapsulated radionuclides are easily leached by the contact of ground water and released in the geosphere. The high ionic strength of the concentrated saline solution also favours the migration of radionuclides in clay host rocks.

In Heidegger's phenomenology, Dasein is always in a meaningful world, but there is always an underlying background for every instance of signification. Thus, although some things may be certain, they have little to do with Dasein's sense of care and existential anxiety, e.g., in the face of death. In calling his work Being and Nothingness an \"essay in phenomenological ontology\" Jean-Paul Sartre follows Heidegger in defining the human essence as ambiguous, or relating fundamentally to such ambiguity. Simone de Beauvoir tries to base an ethics on Heidegger's and Sartre's writings (The Ethics of Ambiguity), where she highlights the need to grapple with ambiguity: \"as long as there have been philosophers and they have thought, most of them have tried to mask it... And the ethics which they have proposed to their disciples has always pursued the same goal. It has been a matter of eliminating the ambiguity by making oneself pure inwardness or pure externality, by escaping from the sensible world or being engulfed by it, by yielding to eternity or enclosing oneself in the pure moment.\" Ethics cannot be based on the authoritative certainty given by mathematics and logic, or prescribed directly from the empirical findings of science. She states: \"Since we do not succeed in fleeing it, let us, therefore, try to look the truth in the face. Let us try to assume our fundamental ambiguity. It is in the knowledge of the genuine conditions of our life that we must draw our strength to live and our reason for acting\". Other continental philosophers suggest that concepts such as life, nature, and sex are ambiguous. Corey Anton has argued that we cannot be certain what is separate from or unified with something else: language, he asserts, divides what is not, in fact, separate. Following Ernest Becker, he argues that the desire to 'authoritatively disambiguate' the world and existence has led to numerous ideologies and historical events such as genocide. On this basis, he argues that ethics must focus on 'dialectically integrating opposites' and balancing tension, rather than seeking a priori validation or certainty.

Shortly thereafter, as more states became interested in meeting to revise the Articles, a meeting was set in Philadelphia on May 25, 1787. This became the Constitutional Convention.

Arthur attended lectures by the prominent post-Kantian philosopher Johann Gottlieb Fichte, but quickly found many points of disagreement with his ; he also found Fichte's lectures tedious and hard to understand. He later mentioned Fichte only in critical, negative terms—seeing his philosophy as a lower-quality version of Kant's and considering it useful only because Fichte's poor arguments unintentionally highlighted some failings of Kantianism.

In Mozambique, this policy spawned a number of companies notorious for their exploitation of local labor. But in Angola, only Diamang showed even moderate success.

During the 1950s, Portugal built dams, hydroelectric power stations, and transportation systems. In addition, Portuguese citizens were encouraged to emigrate to Angola, where planned settlements (colonatos) were established for them in the rural areas.

Relativity and quantum mechanics are together the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed \"the world's most famous equation\". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics \"for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect\", a pivotal step in the development of quantum theory.

He then extended the theory to gravitational fields; he published a paper on general relativity in 1916, introducing his theory of gravitation. In 1917, he applied the general theory of relativity to model the structure of the universe. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules.

Afghanistan would be reunited in the 19th century after wars of unification led by Dost Mohammad Khan, where he conquered the independent principalities in Afghanistan. Dost Mohammad died in 1863, weeks after his last campaign to unite Afghanistan, and as a result, threw Afghanistan back into civil war with his successors.

From India, the British attempted to subjugate Afghanistan but were repelled in the First Anglo-Afghan War. However, the Second Anglo-Afghan War saw a British victory and the successful establishment of British political influence over Afghanistan. Following the Third Anglo-Afghan War in 1919, Afghanistan became free of foreign dominance, and eventually emerged as the independent Kingdom of Afghanistan in June 1926 under Amanullah Khan.

Pre-Islamic Meccans worshiped Allah alongside a host of lesser gods and those whom they called the \"daughters of Allah.\" Islam forbade worship of anyone or thing other than God. Some authors have suggested that polytheistic Arabs used the name as a reference to a creator god or a supreme deity of their pantheon. The term may have been vague in the Meccan religion. According to one hypothesis, which goes back to Julius Wellhausen, Allah (the supreme deity of the tribal federation around Quraysh) was a designation that consecrated the superiority of Hubal (the supreme deity of Quraysh) over the other gods. However, there is also evidence that Allah and Hubal were two distinct deities. According to that hypothesis, the Kaaba was first consecrated to a supreme deity named Allah and then hosted the pantheon of Quraysh after their conquest of Mecca, about a century before the time of Muhammad. Some inscriptions seem to indicate the use of Allah as a name of a polytheist deity centuries earlier, but nothing precise is known about this use. Some scholars have suggested that Allah may have represented a remote creator god who was gradually eclipsed by more particularized local deities. There is disagreement on whether Allah played a major role in the Meccan religious cult. No iconic representation of Allah is known to have existed.

At the simplest level, a way to determine whether the impact of the object on the senses meets the criteria to be considered art is whether it is perceived to be attractive or repulsive. Though perception is always colored by experience, and is necessarily subjective, it is commonly understood that what is not somehow aesthetically satisfying cannot be art. However, \"good\" art is not always or even regularly aesthetically appealing to a majority of viewers. In other words, an artist's prime motivation need not be the pursuit of the aesthetic. Also, art often depicts terrible images made for social, moral, or thought-provoking reasons. For example, Francisco Goya's painting depicting the Spanish shootings of 3 May 1808 is a graphic depiction of a firing squad executing several pleading civilians.

Countless schools have proposed their own ways to define quality, yet they all seem to agree in at least one point: once their aesthetic choices are accepted, the value of the work of art is determined by its capacity to transcend the limits of its chosen medium to strike some universal chord by the rarity of the skill of the artist or in its accurate reflection in what is termed the zeitgeist.

Artists express something so that their audience is aroused to some extent, but they do not have to do so consciously.

[ { "plaintext": "Agnostida is an order of arthropod which have classically been seen as a group of highly modified trilobites, though some recent research has doubted this placement. Regardless, they appear to be close relatives as part of the Artiopoda. They are present in the Lower Cambrian fossil record along with trilobites from the Redlichiida, Corynexochida, and Ptychopariida orders, and were highly diverse throughout the Cambrian.

The challenge to the status has focused on Agnostina partly due to the juveniles of one genus have been found with legs differing dramatically from those of adult trilobites, suggesting they are not members of the lamellipedian clade, of which trilobites are a part. Instead, the limbs of agnostids closely resemble those of stem group crustaceans, although they lack the proximal endite, which defines that group. The study suggested that they were likely the sister taxon to the crustacean stem lineage, and, as such, part of the clade, Crustaceomorpha. Other researchers have suggested, based on a cladistic analyses of dorsal exoskeletal features, that Eodiscina and Agnostida are closely united, and the Eodiscina descended from the trilobite order Ptychopariida. A 2019 study of adult specimens with preserved soft tissue from the Burgess Shale found that agnostidans shared morphological similarities to trilobites and other related artiopodans like nektaspids, and their placement as stem-crustaceans was unsupported.

Their lack of eyes, a morphology not well-suited for swimming, and their fossils found in association with other benthic trilobites suggest a benthic (bottom-dwelling) mode of life.

Their wide geographic dispersion in the fossil record is uncharacteristic of benthic animals, suggesting a pelagic existence. The thoracic segment appears to form a hinge between the head and pygidium allowing for a bivalved ostracodan-type lifestyle.
