100 | Religious humanism is an integration of humanist ethical philosophy with religious rituals and beliefs that centre on human needs, interests, and abilities. Though practitioners of religious humanism did not officially organise under the name of "humanism" until the late 19th and early 20th centuries, non-theistic religions paired with human-centred ethical philosophy have a long history. The Cult of Reason (French: Culte de la Raison) was a religion based on deism devised during the French Revolution by Jacques Hébert, Pierre Gaspard Chaumette and their supporters. In 1793 during the French Revolution, the cathedral Notre Dame de Paris was turned into a "Temple to Reason" and for a time Lady Liberty replaced the Virgin Mary on several altars. In the 1850s, Auguste Comte, the Father of Sociology, founded Positivism, a "religion of humanity". One of the earliest forerunners of contemporary chartered humanist organisations was the Humanistic Religious Association formed in 1853 in London. This early group was democratically organised, with male and female members participating in the election of the leadership and promoted knowledge of the sciences, philosophy, and the arts. The Ethical Culture movement was founded in 1876. The movement's founder, Felix Adler, a former member of the Free Religious Association, conceived of Ethical Culture as a new religion that would retain the ethical message at the heart of all religions. Ethical Culture was religious in the sense of playing a defining role in people's lives and addressing issues of ultimate concern. | Who founded a religion whose cornerstone was deism? | 573287a106a3a419008acad1 | 510 | Jacques Hébert |

102 | Polemics about humanism have sometimes assumed paradoxical twists and turns. Early 20th century critics such as Ezra Pound, T. E. Hulme, and T. S. Eliot considered humanism to be sentimental "slop" (Hulme)[citation needed] or "an old bitch gone in the teeth" (Pound) and wanted to go back to a more manly, authoritarian society such as (they believed) existed in the Middle Ages. Postmodern critics who are self-described anti-humanists, such as Jean-François Lyotard and Michel Foucault, have asserted that humanism posits an overarching and excessively abstract notion of humanity or universal human nature, which can then be used as a pretext for imperialism and domination of those deemed somehow less than human. "Humanism fabricates the human as much as it fabricates the nonhuman animal", suggests Timothy Laurie, turning the human into what he calls "a placeholder for a range of attributes that have been considered most virtuous among humans (e.g. rationality, altruism), rather than most commonplace (e.g. hunger, anger)". Nevertheless, philosopher Kate Soper notes that by faulting humanism for falling short of its own benevolent ideals, anti-humanism thus frequently "secretes a humanist rhetoric". | Who was one early naysayer of Humanism? | 57328842b9988014000c7666 | 112 | Ezra Pound |

106 | In his book, Humanism (1997), Tony Davies calls these critics "humanist anti-humanists". Critics of antihumanism, most notably Jürgen Habermas, counter that while antihumanists may highlight humanism's failure to fulfil its emancipatory ideal, they do not offer an alternative emancipatory project of their own. Others, like the German philosopher Heidegger considered themselves humanists on the model of the ancient Greeks, but thought humanism applied only to the German "race" and specifically to the Nazis and thus, in Davies' words, were anti-humanist humanists. Such a reading of Heidegger's thought is itself deeply controversial; Heidegger includes his own views and critique of Humanism in Letter On Humanism. Davies acknowledges that after the horrific experiences of the wars of the 20th century "it should no longer be possible to formulate phrases like 'the destiny of man' or the 'triumph of human reason' without an instant consciousness of the folly and brutality they drag behind them". For "it is almost impossible to think of a crime that has not been committed in the name of human reason". Yet, he continues, "it would be unwise to simply abandon the ground occupied by the historical humanisms. For one thing humanism remains on many occasions the only available alternative to bigotry and persecution. The freedom to speak and write, to organise and campaign in defence of individual or collective interests, to protest and disobey: all these can only be articulated in humanist terms." | In what year was the book humanism published? | 5732889806a3a419008acae1 | 23 | 1997 |

110 | The ad fontes principle also had many applications. The re-discovery of ancient manuscripts brought a more profound and accurate knowledge of ancient philosophical schools such as Epicureanism, and Neoplatonism, whose Pagan wisdom the humanists, like the Church fathers of old, tended, at least initially, to consider as deriving from divine revelation and thus adaptable to a life of Christian virtue. The line from a drama of Terence, Homo sum, humani nihil a me alienum puto (or with nil for nihil), meaning "I am a human being, I think nothing human alien to me", known since antiquity through the endorsement of Saint Augustine, gained renewed currency as epitomising the humanist attitude. The statement, in a play modeled or borrowed from a (now lost) Greek comedy by Menander, may have originated in a lighthearted vein – as a comic rationale for an old man's meddling – but it quickly became a proverb and throughout the ages was quoted with a deeper meaning, by Cicero and Saint Augustine, to name a few, and most notably by Seneca.

114 | Davies identifies Paine's The Age of Reason as "the link between the two major narratives of what Jean-François Lyotard calls the narrative of legitimation": the rationalism of the 18th-century Philosophes and the radical, historically based German 19th-century Biblical criticism of the Hegelians David Friedrich Strauss and Ludwig Feuerbach. "The first is political, largely French in inspiration, and projects 'humanity as the hero of liberty'. The second is philosophical, German, seeks the totality and autonomy of knowledge, and stresses understanding rather than freedom as the key to human fulfilment and emancipation. The two themes converged and competed in complex ways in the 19th century and beyond, and between them set the boundaries of its various humanisms.

0 | Earth was initially molten due to extreme volcanism and frequent collisions with other bodies. Eventually, the outer layer of the planet cooled to form a solid crust when water began accumulating in the atmosphere. The Moon formed soon afterwards, possibly as the result of a Mars-sized object with about 10% of the Earth's mass impacting the planet in a glancing blow. Some of this object's mass merged with the Earth, significantly altering its internal composition, and a portion was ejected into space. Some of the material survived to form an orbiting moon. Outgassing and volcanic activity produced the primordial atmosphere.

9 | The Earth of the early Archean (4,000 to 2,500 million years ago) may have had a different tectonic style. During this time, the Earth's crust cooled enough that rocks and continental plates began to form. Some scientists think because the Earth was hotter, that plate tectonic activity was more vigorous than it is today, resulting in a much greater rate of recycling of crustal material. This may have prevented cratonisation and continent formation until the mantle cooled and convection slowed down. Others argue that the subcontinental lithospheric mantle is too buoyant to subduct and that the lack of Archean rocks is a function of erosion and subsequent tectonic events. | During what time period was the Archean era? | 57328a3b57eb1f1400fd2d90 | 32 | 4,000 to 2,500 million years ago |

14 | In contrast to the Proterozoic, Archean rocks are often heavily metamorphized deep-water sediments, such as graywackes, mudstones, volcanic sediments and banded iron formations. Greenstone belts are typical Archean formations, consisting of alternating high- and low-grade metamorphic rocks. The high-grade rocks were derived from volcanic island arcs, while the low-grade metamorphic rocks represent deep-sea sediments eroded from the neighboring island frogs and deposited in a forearc basin.

24 | The Paleozoic spanned from roughly 541 to 252 million years ago (Ma) and is subdivided into six geologic periods; from oldest to youngest they are the Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian. Geologically, the Paleozoic starts shortly after the breakup of a supercontinent called Pannotia and at the end of a global ice age. Throughout the early Paleozoic, the Earth's landmass was broken up into a substantial number of relatively small continents.

29 | The Cambrian is a major division of the geologic timescale that begins about 541.0 ± 1.0 Ma. Cambrian continents are thought to have resulted from the breakup of a Neoproterozoic supercontinent called Pannotia. The waters of the Cambrian period appear to have been widespread and shallow. Continental drift rates may have been anomalously high. Laurentia, Baltica and Siberia remained independent continents following the break-up of the supercontinent of Pannotia.

34 | The Ordovician Period started at a major extinction event called the Cambrian-Ordovician extinction events some time about 485.4 ± 1.9 Ma. During the Ordovician the southern continents were collected into a single continent called Gondwana. Gondwana started the period in the equatorial latitudes and, as the period progressed, drifted toward the South Pole. Early in the Ordovician the continents Laurentia, Siberia and Baltica were still independent continents (since the break-up of the supercontinent Pannotia earlier), but Baltica began to move toward Laurentia later in the period, causing the Iapetus Ocean to shrink between them. Also, Avalonia broke free from Gondwana and began to head north toward Laurentia. The Rheic Ocean was formed as a result of this.

39 | The most-commonly accepted theory is that these events were triggered by the onset of an ice age, in the Hirnantian faunal stage that ended the long, stable greenhouse conditions typical of the Ordovician. The ice age was probably not as long-lasting as once thought; study of oxygen isotopes in fossil brachiopods shows that it was probably no longer than 0.5 to 1.5 million years. The event was preceded by a fall in atmospheric carbon dioxide (from 7000ppm to 4400ppm) which selectively affected the shallow seas where most organisms lived.

49 | The Devonian spanned roughly from 419 to 359 Ma. The period was a time of great tectonic activity, as Laurasia and Gondwana drew closer together. The continent Euramerica (or Laurussia) was created in the early Devonian by the collision of Laurentia and Baltica, which rotated into the natural dry zone along the Tropic of Capricorn. In these near-deserts, the Old Red Sandstone sedimentary beds formed, made red by the oxidized iron (hematite) characteristic of drought conditions. Near the equator Pangaea began to consolidate from the plates containing North America and Europe, further raising the northern Appalachian Mountains and forming the Caledonian Mountains in Great Britain and Scandinavia. The southern continents remained tied together in the supercontinent of Gondwana. The remainder of modern Eurasia lay in the Northern Hemisphere. Sea levels were high worldwide, and much of the land lay submerged under shallow seas. The deep, enormous Panthalassa (the "universal ocean") covered the rest of the planet. Other minor oceans were Paleo-Tethys, Proto-Tethys, Rheic Ocean and Ural Ocean (which was closed during the collision with Siberia and Baltica). | During what time period was the Devonian era? | 573295af0d034c1900ab002b | 34 | 419 to 359 Ma. |

54 | A global drop in sea level at the end of the Devonian reversed early in the Carboniferous; this created the widespread epicontinental seas and carbonate deposition of the Mississippian. There was also a drop in south polar temperatures; southern Gondwana was glaciated throughout the period, though it is uncertain if the ice sheets were a holdover from the Devonian or not. These conditions apparently had little effect in the deep tropics, where lush coal swamps flourished within 30 degrees of the northernmost glaciers. A mid-Carboniferous drop in sea-level precipitated a major marine extinction, one that hit crinoids and ammonites especially hard. This sea-level drop and the associated unconformity in North America separate the Mississippian Period from the Pennsylvanian period. | What occurred to the level of the sea when the Devonian period was finished? | 573296cbb4fa5219003da0da | 0 | A global drop |

59 | The Carboniferous was a time of active mountain building, as the supercontinent Pangea came together. The southern continents remained tied together in the supercontinent Gondwana, which collided with North America-Europe (Laurussia) along the present line of eastern North America. This continental collision resulted in the Hercynian orogeny in Europe, and the Alleghenian orogeny in North America; it also extended the newly uplifted Appalachians southwestward as the Ouachita Mountains. In the same time frame, much of present eastern Eurasian plate welded itself to Europe along the line of the Ural mountains. There were two major oceans in the Carboniferous the Panthalassa and Paleo-Tethys. Other minor oceans were shrinking and eventually closed the Rheic Ocean (closed by the assembly of South and North America), the small, shallow Ural Ocean (which was closed by the collision of Baltica, and Siberia continents, creating the Ural Mountains) and Proto-Tethys Ocean. | What geologic events took place when Pangea combined during the Carboniferous? | 5732978b0342181400a20289 | 39 | mountain building |

64 | During the Permian all the Earth's major land masses, except portions of East Asia, were collected into a single supercontinent known as Pangaea. Pangaea straddled the equator and extended toward the poles, with a corresponding effect on ocean currents in the single great ocean (Panthalassa, the universal sea), and the Paleo-Tethys Ocean, a large ocean that was between Asia and Gondwana. The Cimmeria continent rifted away from Gondwana and drifted north to Laurasia, causing the Paleo-Tethys to shrink. A new ocean was growing on its southern end, the Tethys Ocean, an ocean that would dominate much of the Mesozoic Era. Large continental landmasses create climates with extreme variations of heat and cold ("continental climate") and monsoon conditions with highly seasonal rainfall patterns.

69 | The remainder was the world-ocean known as Panthalassa ("all the sea"). All the deep-ocean sediments laid down during the Triassic have disappeared through subduction of oceanic plates; thus, very little is known of the Triassic open ocean. The supercontinent Pangaea was rifting during the Triassic—especially late in the period—but had not yet separated. The first nonmarine sediments in the rift that marks the initial break-up of Pangea—which separated New Jersey from Morocco—are of Late Triassic age; in the U.S., these thick sediments comprise the Newark Supergroup. Because of the limited shoreline of one super-continental mass, Triassic marine deposits are globally relatively rare; despite their prominence in Western Europe, where the Triassic was first studied. In North America, for example, marine deposits are limited to a few exposures in the west.

74 | The Jurassic Period extends from about 201.3 ± 0.2 to 145.0 Ma. During the early Jurassic, the supercontinent Pangaea broke up into the northern supercontinent Laurasia and the southern supercontinent Gondwana; the Gulf of Mexico opened in the new rift between North America and what is now Mexico's Yucatan Peninsula. The Jurassic North Atlantic Ocean was relatively narrow, while the South Atlantic did not open until the following Cretaceous Period, when Gondwana itself rifted apart. The Tethys Sea closed, and the Neotethys basin appeared. Climates were warm, with no evidence of glaciation. As in the Triassic, there was apparently no land near either pole, and no extensive ice caps existed. The Jurassic geological record is good in western Europe, where extensive marine sequences indicate a time when much of the continent was submerged under shallow tropical seas; famous locales include the Jurassic Coast World Heritage Site and the renowned late Jurassic lagerstätten of Holzmaden and Solnhofen. In contrast, the North American Jurassic record is the poorest of the Mesozoic, with few outcrops at the surface. Though the epicontinental Sundance Sea left marine deposits in parts of the northern plains of the United States and Canada during the late Jurassic, most exposed sediments from this period are continental, such as the alluvial deposits of the Morrison Formation. The first of several massive batholiths were emplaced in the northern Cordillera beginning in the mid-Jurassic, marking the Nevadan orogeny.

Important Jurassic exposures are also found in Russia, India, South America, Japan, Australasia and the United Kingdom. | At what point did the South Atlantic ocean begin to open? | 5732a0bad6dcfa19001e8a3d | 434 | Cretaceous Period |
78 | The Jurassic Period extends from about 201.3 ± 0.2 to 145.0 Ma. During the early Jurassic, the supercontinent Pangaea broke up into the northern supercontinent Laurasia and the southern supercontinent Gondwana; the Gulf of Mexico opened in the new rift between North America and what is now Mexico's Yucatan Peninsula. The Jurassic North Atlantic Ocean was relatively narrow, while the South Atlantic did not open until the following Cretaceous Period, when Gondwana itself rifted apart. The Tethys Sea closed, and the Neotethys basin appeared. Climates were warm, with no evidence of glaciation. As in the Triassic, there was apparently no land near either pole, and no extensive ice caps existed. The Jurassic geological record is good in western Europe, where extensive marine sequences indicate a time when much of the continent was submerged under shallow tropical seas; famous locales include the Jurassic Coast World Heritage Site and the renowned late Jurassic lagerstätten of Holzmaden and Solnhofen. In contrast, the North American Jurassic record is the poorest of the Mesozoic, with few outcrops at the surface.

79 | During the Cretaceous, the late Paleozoic-early Mesozoic supercontinent of Pangaea completed its breakup into present day continents, although their positions were substantially different at the time. As the Atlantic Ocean widened, the convergent-margin orogenies that had begun during the Jurassic continued in the North American Cordillera, as the Nevadan orogeny was followed by the Sevier and Laramide orogenies. Though Gondwana was still intact in the beginning of the Cretaceous, Gondwana itself broke up as South America, Antarctica and Australia rifted away from Africa (though India and Madagascar remained attached to each other); thus, the South Atlantic and Indian Oceans were newly formed. Such active rifting lifted great undersea mountain chains along the welts, raising eustatic sea levels worldwide. | The current continents were formerly known as what continent? | 5732a189d6dcfa19001e8a44 | 75 | Pangaea |
