Clarence Irving Lewis
Clarence Irving Lewis (April 12, 1883 – February 3, 1964), usually cited as C. I. Lewis, was an American academic philosopher and the founder of conceptual pragmatism.[1] First a noted logician, he later branched into epistemology, and during the last 20 years of his life, he wrote much on ethics. The New York Times memorialized him as "a leading authority on symbolic logic and on the philoso

Circum-Saharan Prehistory through the Lens of mtDNA Diversity
African history has been significantly influenced by the Sahara, which has represented a barrier for migrations of all living beings, including humans. Major exceptions were the gene flow events that took place between North African and sub-Saharan populations during the so-called African Humid Periods, especially in the Early Holocene (11.5 to 5.5 thousand years ago), and more recently in connection with trans-Saharan commercial routes. The research indicates that maternal gene flow must have been important in this circum-Saharan space, not only within North Africa and the Sahel/Savannah belt but also between these two regions.

Circular-economy in the Built Environment
       The circular economy in the building sector is an approach aiming at minimizing waste and emissions, as well as closing water, energy, and material loops. Under a circular built environment, landfilling is no longer an option to handle construction and demolition waste, and design for disassembly has a central role. Design for disassembly is a concept in which buildings and products are designed intentionally for material recovery, value retention, and meaningful next use.

Church of Our Father (Atlanta)
Church of Our Father was the first Unitarian church established in Atlanta, Georgia. The church was organized on March 27, 1883, by Rev. George Leonard Chaney, a Boston minister. Rev. Chaney initially held Sunday services in the Senate Chamber, Concordia Hall and the United States Courtroom. A church building was constructed at the corner of North Forsyth and Church Street and dedicated on April 23, 1884. The original building was demolished in 1900. The church continued to serve Atlanta's liberal religious community for more than six decades. During that time the church name was changed several times. In 1918, Atlanta's Unitarians merged with the city's Universalist congregation. The combined congregation collapsed in 1951.

Chronology of Jesus
A chronology of Jesus aims to establish a timeline for the events of the life of Jesus. Scholars have correlated Jewish and Greco-Roman documents and astronomical calendars with the New Testament accounts to estimate dates for the major events in Jesus's life. Two main approaches have been used to estimate the year of the birth of Jesus: one based on the accounts in the Gospels of his birth with reference to King Herod's reign, and the other by subtracting his stated age of "about 30 years" when he began preaching. Most scholars, on this basis, assume a date of birth between 6 and 4 BC. Three details have been used to estimate the year when Jesus began preaching: a mention of his age of "about 30 years" during "the fifteenth year" of the reign of Tiberius Caesar, another relating to the date of the building of the Temple in Jerusalem, and yet another concerning the death of John the Baptist. Hence, scholars estimate that Jesus began preaching and gathering followers around AD 28–29. According to the three synoptic gospels Jesus continued preaching for at least one year, and according to John the Evangelist for three years. Five methods have been used to estimate the date of the crucifixion of Jesus. One uses non-Christian sources such as Josephus and Tacitus. Another works backwards from the historically well-established trial of the Apostle Paul by the Roman proconsul Gallio in Corinth in AD 51/52 to estimate the date of Paul's conversion. Both methods result in AD 36 as an upper bound to the crucifixion. Thus, scholars generally agree that Jesus was crucified between AD 30 and AD 36. Isaac Newton's astronomical method calculates those ancient Passovers (always defined by a full moon) which are preceded by a Friday, as specified by all four Gospels; this leaves two potential crucifixion dates, 7 April AD 30 and 3 April AD 33. In the lunar eclipse method, the Apostle Peter's statement that the moon turned to blood at the crucifixion (Acts of the Apostles 2:14-21) is taken to refer to the lunar eclipse of 3 April AD 33; although astronomers are discussing whether the eclipse was visible as far west as Jerusalem. Recent astronomical research uses the contrast between the synoptic date of Jesus' last Passover on the one hand with John's date of the subsequent "Jewish Passover" on the other hand, to propose Jesus' Last Supper to have been on Wednesday, 1 April AD 33 and the crucifixion on Friday 3 April AD 33.

Chronographer
A chronographer was a graphical representation of historical information devised by American educator Emma Willard in the mid-19th century. The chronographers intended to show historical information in a geographic and chronological context. The first graphic was Picture of Nations, published in 1835, which showed civilizations as streams running through time, becoming wider and narrower as they gained or lost influence. She developed another chronographer, the Chronographer of American History, in 1844, showing the history of the United States as events marked on the branches of a tree. Later chronographers showed historical events within an imagined Ancient Greek temple; the Temple of Time (1846), American Temple of Time (late 1840s), English Chronographer (1849) and Chronographer of Ancient History (1851) are examples of this type. In these chronographers the floor was occupied with the streams of civilizations, as in the Picture of Nations; the walls (often colonnaded) denoted the passage of time and were marked with historical leaders and the roof was split into categories to list other historic persons. The back wall of the temple was often marked as the point of biblical creation, sometimes with the date of 4004 BC from the Ussher chronology, though in her American Temple of Time a map of the continent is used. The birth of Christ was often denoted with a white star and other biblical figures included. Willard's chronographers were intended as learning aids, allowing students to place themselves within the imaginary temple and to consider events in their historic and geographic context. She presented her chronographers at the Great Exhibition in London in 1851 and received a medal and certificate from Albert, Prince Consort. Willard's work has been disparaged by later writers, including for their almost complete omission of non-Western peoples and events.

Christianity and Theosophy
Christianity and Theosophy, for more than a hundred years, have had a "complex and sometimes troubled" relationship. The Christian faith was the native religion of the great majority of Western Theosophists, but many came to Theosophy through a process of opposition to Christianity. According to professor Robert S. Ellwood, "the whole matter has been a divisive issue within Theosophy."

Christianity and Science
Most sources of knowledge available to early Christians were connected to pagan world-views. There were various opinions on how Christianity should regard pagan learning, which included its ideas about nature. For instance, among early Christian teachers, Tertullian (c. 160–220) held a generally negative opinion of Greek philosophy, while Origen (c. 185–254) regarded it much more favorably and required his students to read nearly every work available to them. Historically, Christianity has often been a patron of sciences. It has been prolific in the foundation of schools, universities and hospitals, and many clergy have been active in the sciences. Historians of science such as Pierre Duhem credit medieval Catholic mathematicians and philosophers such as John Buridan, Nicole Oresme and Roger Bacon as the founders of modern science. Duhem concluded that "the mechanics and physics of which modern times are justifiably proud to proceed, by an uninterrupted series of scarcely perceptible improvements, from doctrines professed in the heart of the medieval schools".

Christian Views on Hell
In Christian theology, Hell is the place or state into which, by God's definitive judgment, unrepentant sinners pass in the general judgment, or, as some Christians believe, immediately after death (particular judgment). Its character is inferred from teaching in the biblical texts, some of which, interpreted literally, have given rise to the popular idea of Hell. Theologians today generally see Hell as the logical consequence of using free will to reject union with God and, because God will not force conformity, it is not incompatible with God's justice and mercy. Different Hebrew and Greek words are translated as "Hell" in most English-language Bibles. These words include: "Sheol" in the Hebrew Bible, and "Hades" in the New Testament. Many modern versions, such as the New International Version, translate Sheol as "grave" and simply transliterate "Hades". It is generally agreed that both sheol and hades do not typically refer to the place of eternal punishment, but to the grave, the temporary abode of the dead, the underworld. "Gehenna" in the New Testament, where it is described as a place where both soul and body could be destroyed (Matthew 10:28) in "unquenchable fire" (Mark 9:43). The word is translated as either "Hell" or "Hell fire" in many English versions. Gehenna was a physical location outside the city walls where they burned garbage and where lepers and outcasts were sent, hence the weeping and gnashing of teeth. The Greek verb ταρταρῶ (tartarō, derived from Tartarus), which occurs once in the New Testament (in 2 Peter 2:4), is almost always translated by a phrase such as "thrown down to hell". A few translations render it as "Tartarus"; of this term, the Holman Christian Standard Bible states: "Tartarus is a Greek name for a subterranean place of divine punishment lower than Hades."
