Aristotle was a philosopher during the Classical period in Ancient Greece, the founder of the Lyceum and the Peripatetic school of philosophy and Aristotelian tradition. Along with his teacher Plato, he is considered the "Father of Western Philosophy", his writings cover many subjects – including physics, zoology, logic, aesthetics, theatre, rhetoric, linguistics, economics and government. Aristotle provided a complex synthesis of the various philosophies existing prior to him, it was above all from his teachings that the West inherited its intellectual lexicon, as well as problems and methods of inquiry; as a result, his philosophy has exerted a unique influence on every form of knowledge in the West and it continues to be a subject of contemporary philosophical discussion. Little is known about his life. Aristotle was born in the city of Stagira in Northern Greece, his father, died when Aristotle was a child, he was brought up by a guardian. At seventeen or eighteen years of age, he joined Plato's Academy in Athens and remained there until the age of thirty-seven.
Shortly after Plato died, Aristotle left Athens and, at the request of Philip II of Macedon, tutored Alexander the Great beginning in 343 BC. He established a library in the Lyceum which helped him to produce many of his hundreds of books on papyrus scrolls. Though Aristotle wrote many elegant treatises and dialogues for publication, only around a third of his original output has survived, none of it intended for publication; the fact that Aristotle was a pupil of Plato contributed to his former views of Platonism, following Plato's death, Aristotle developed an increased interest in natural sciences and adopted the position of immanent realism. Aristotle's views on physical science profoundly shaped medieval scholarship, their influence extended from Late Antiquity and the Early Middle Ages into the Renaissance, were not replaced systematically until the Enlightenment and theories such as classical mechanics. Some of Aristotle's zoological observations found in his biology, such as on the hectocotyl arm of the octopus, were disbelieved until the 19th century.
His works contain the earliest known formal study of logic, studied by medieval scholars such as Peter Abelard and John Buridan. Aristotle's influence on logic continued well into the 19th century He influenced Islamic thought during the Middle Ages, as well as Christian theology the Neoplatonism of the Early Church and the scholastic tradition of the Catholic Church. Aristotle was revered among medieval Muslim scholars as "The First Teacher" and among medieval Christians like Thomas Aquinas as "The Philosopher", his ethics, though always influential, gained renewed interest with the modern advent of virtue ethics, such as in the thinking of Alasdair MacIntyre and Philippa Foot. In general, the details of Aristotle's life are not well-established; the biographies written in ancient times are speculative and historians only agree on a few salient points. Aristotle, whose name means "the best purpose" in Ancient Greek, was born in 384 BC in Stagira, about 55 km east of modern-day Thessaloniki.
His father Nicomachus was the personal physician to King Amyntas of Macedon. Both of Aristotle's parents died when he was about thirteen, Proxenus of Atarneus became his guardian. Although little information about Aristotle's childhood has survived, he spent some time within the Macedonian palace, making his first connections with the Macedonian monarchy. At the age of seventeen or eighteen, Aristotle moved to Athens to continue his education at Plato's Academy, he remained there for nearly twenty years before leaving Athens in 348/47 BC. The traditional story about his departure records that he was disappointed with the Academy's direction after control passed to Plato's nephew Speusippus, although it is possible that he feared the anti-Macedonian sentiments in Athens at that time and left before Plato died. Aristotle accompanied Xenocrates to the court of his friend Hermias of Atarneus in Asia Minor. After the death of Hermias, Aristotle travelled with his pupil Theophrastus to the island of Lesbos, where together they researched the botany and zoology of the island and its sheltered lagoon.
While in Lesbos, Aristotle married Hermias's adoptive daughter or niece. She bore him a daughter, whom they named Pythias. In 343 BC, Aristotle was invited by Philip II of Macedon to become the tutor to his son Alexander. Aristotle was appointed as the head of the royal academy of Macedon. During Aristotle's time in the Macedonian court, he gave lessons not only to Alexander, but to two other future kings: Ptolemy and Cassander. Aristotle encouraged Alexander toward eastern conquest and Aristotle's own attitude towards Persia was unabashedly ethnocentric. In one famous example, he counsels Alexander to be "a leader to the Greeks and a despot to the barbarians, to look after the former as after friends and relatives, to deal with the latter as with beasts or plants". By 335 BC, Aristotle had returned to Athens. Aristotle conducted courses at the school for the next twelve years. While in Athens, his wife Pythias died and Aristotle became involved with Herpyllis of Stagira, who bore him a son whom he named after his father, Nicomachus.
According to the Suda, he had an erômenos, Palaephatus of Abydus. This period in Athens, between 335 and 323 BC, is when Aristotle is believed to have composed many of his works, he wrote many dialogues. Those works that have survived are in treatise form and were not
Erhard Ratdolt was an early German printer from Augsburg. He was active as a printer in Venice from 1476 to 1486, afterwards in Augsburg. From 1475 to 1478 he was in partnership with two other German printers; the first book the partnership produced was the Calendarium and published by Regiomontanus, which offered one of the earliest examples of a modern title page. Other noteworthy publications are the Historia Romana of Appianus, the first edition of Euclid's Elements, where he solved the problem of printing geometric diagrams, the Poeticon astronomicon from 1482, Haly Abenragel, Alchabitius. Ratdolt is famous for having produced the first known printer's type specimen book, his innovations of layout and typography, mixing type and woodcuts, have subsequently been much admired. His graphic choices and technical solutions influenced those of William Morris.

Islamic Golden Age
The Islamic Golden Age was a period of cultural and scientific flourishing in the history of Islam, traditionally dated from the 8th century to the 14th century. This period is traditionally understood to have begun during the reign of the Abbasid caliph Harun al-Rashid with the inauguration of the House of Wisdom in Baghdad, where scholars from various parts of the world with different cultural backgrounds were mandated to gather and translate all of the world's classical knowledge into the Arabic language; this period is traditionally said to have ended with the collapse of the Abbasid caliphate due to Mongol invasions and the Siege of Baghdad in 1258 AD. A few contemporary scholars place the end of the Islamic Golden Age as late as the end of 15th to 16th centuries; the metaphor of a golden age began to be applied in 19th-century literature about Islamic history, in the context of the western aesthetic fashion known as Orientalism. The author of a Handbook for Travelers in Syria and Palestine in 1868 observed that the most beautiful mosques of Damascus were "like Mohammedanism itself, now decaying" and relics of "the golden age of Islam".
There is no unambiguous definition of the term, depending on whether it is used with a focus on cultural or on military achievement, it may be taken to refer to rather disparate time spans. Thus, one 19th century author would have it extend to the duration of the caliphate, or to "six and a half centuries", while another would have it end after only a few decades of Rashidun conquests, with the death of Umar and the First Fitna. During the early 20th century, the term was used only and referred to the early military successes of the Rashidun caliphs, it was only in the second half of the 20th century that the term came to be used with any frequency, now referring to the cultural flourishing of science and mathematics under the caliphates during the 9th to 11th centuries, but extended to include part of the late 8th or the 12th to early 13th centuries. Definitions may still vary considerably. Equating the end of the golden age with the end of the caliphates is a convenient cut-off point based on a historical landmark, but it can be argued that Islamic culture had entered a gradual decline much earlier.
The various Quranic injunctions and Hadith, which place values on education and emphasize the importance of acquiring knowledge, played a vital role in influencing the Muslims of this age in their search for knowledge and the development of the body of science. The Islamic Empire patronized scholars; the money spent on the Translation Movement for some translations is estimated to be equivalent to about twice the annual research budget of the United Kingdom’s Medical Research Council. The best scholars and notable translators, such as Hunayn ibn Ishaq, had salaries that are estimated to be the equivalent of professional athletes today; the House of Wisdom was a library established in Iraq by Caliph al-Mansur. During this period, the Muslims showed a strong interest in assimilating the scientific knowledge of the civilizations, conquered. Many classic works of antiquity that might otherwise have been lost were translated from Greek, Indian, Chinese and Phoenician civilizations into Arabic and Persian, in turn translated into Turkish and Latin.
Christians the adherents of the Church of the East, contributed to Islamic civilization during the reign of the Ummayads and the Abbasids by translating works of Greek philosophers and ancient science to Syriac and afterwards to Arabic. They excelled in many fields, in particular philosophy and theology. For a long period of time the personal physicians of the Abbasid Caliphs were Assyrian Christians. Among the most prominent Christian families to serve as physicians to the caliphs were the Bukhtishu dynasty. Throughout the 4th to 7th centuries, Christian scholarly work in the Greek and Syriac languages was either newly translated or had been preserved since the Hellenistic period. Among the prominent centers of learning and transmission of classical wisdom were Christian colleges such as the School of Nisibis and the School of Edessa, the pagan University of Harran and the renowned hospital and medical academy of Jundishapur, the intellectual and scientific center of the Church of the East.
The House of Wisdom was founded in Baghdad in 825, modelled after the Academy of Gondishapur. It was led with the support of Byzantine medicine. Many of the most important philosophical and scientific works of the ancient world were translated, including the work of Galen, Plato, Aristotle and Archimedes. Many scholars of the House of Wisdom were of Christian background. Among the various countries and cultures conquered through successive Islamic conquests, a remarkable number of scientists originated from Persia, who contributed immensely to the scientific flourishing of the Islamic Golden Age. According to Bernard Lewis: "Culturally and most remarkable of all religiously, the Persian contribution to this new Islamic civilization is of immense importance; the wo
Abu Sa'id Ahmed ibn Mohammed ibn Abd al-Jalil al-Sijzi was an Iranian Muslim astronomer and astrologer. He is notable for his correspondence with al-Biruni and for proposing that the Earth rotates around its axis in the 10th century, he dedicated work to'Adud al-Daula, his patron, to the prince of Balkh. He worked in Shiraz making astronomical observations from 969 to 970. Al-Sijzi studied intersections of conic circles, he replaced the old kinematical trisection of an angle by a purely geometric solution Al-Biruni tells us that Al-Sijzi invented an astrolabe, called "al-zūraqī", whose design was based on the idea that the Earth rotates: I have seen the astrolabe called Zuraqi invented by Abu Sa'id Sijzi. I liked it much and praised him a great deal, as it is based on the idea entertained by some to the effect that the motion we see is due to the Earth's movement and not to that of the sky. By my life, it is a problem difficult of refutation. For it is the same whether you take it that the Earth is in the sky.
For, in both cases, it does not affect the Astronomical Science. It is just for the physicist to see. Al-Biruni referred to Al-Sijzi as a prominent astronomer who defended the theory that the earth rotates in al-Qānūn al-Masʿūdī; the fact that some people did believe that the earth is moving on its own axis is further confirmed by a reference from the 13th century which states: "According to the geometers, the earth is in constant circular motion, what appears to be the motion of the heavens is due to the motion of the earth and not the stars."

Abu Yūsuf Yaʻqūb ibn ʼIsḥāq aṣ-Ṣabbāḥ al-Kindī was an Arab Muslim philosopher, mathematician and musician. Al-Kindi was the first of the Muslim peripatetic philosophers, is unanimously hailed as the "father of Arab philosophy" for his synthesis and promotion of Greek and Hellenistic philosophy in the Muslim world. Al-Kindi was educated in Baghdad, he became a prominent figure in the House of Wisdom, a number of Abbasid Caliphs appointed him to oversee the translation of Greek scientific and philosophical texts into the Arabic language. This contact with "the philosophy of the ancients" had a profound effect on his intellectual development, led him to write hundreds of original treatises of his own on a range of subjects ranging from metaphysics, ethics and psychology, to medicine, mathematics, astronomy and optics, further afield to more practical topics like perfumes, jewels, dyes, tides, mirrors and earthquakes. In the field of mathematics, al-Kindi played an important role in introducing Indian numerals to the Islamic and Christian world.
Al-Kindi was one of the fathers of cryptography. His book entitled Manuscript on Deciphering Cryptographic Messages gave rise to the birth of cryptanalysis, was the earliest known use of statistical inference, introduced several new methods of breaking ciphers. Using his mathematical and medical expertise, he was able to develop a scale that would allow doctors to quantify the potency of their medication; the central theme underpinning al-Kindi's philosophical writings is the compatibility between philosophy and other "orthodox" Islamic sciences theology. And many of his works deal with subjects; these include the nature of the soul and prophetic knowledge. But despite the important role he played in making philosophy accessible to Muslim intellectuals, his own philosophical output was overshadowed by that of al-Farabi and few of his texts are available for modern scholars to examine. Al-Kindi was born in Kufa to an aristocratic family of the Kinda tribe, descended from the chieftain al-Ash'ath ibn Qays, a contemporary of Muhammad.
The family belonged to the most prominent families of the tribal nobility of Kufa in the early Islamic period, until it lost much of its power following the revolt of Abd al-Rahman ibn Muhammad ibn al-Ash'ath. His father Ishaq was the governor of Kufa, al-Kindi received his preliminary education there, he went to complete his studies in Baghdad, where he was patronized by the Abbasid caliphs al-Ma'mun and al-Mu'tasim. On account of his learning and aptitude for study, al-Ma'mun appointed him to the House of Wisdom, a established centre for the translation of Greek philosophical and scientific texts, in Baghdad, he was well known for his beautiful calligraphy, at one point was employed as a calligrapher by al-Mutawakkil. When al-Ma'mun died, his brother, al-Mu'tasim became Caliph. Al-Kindi's position would be enhanced under al-Mu ` tasim, but on the accession of al-Wāthiq, of al-Mutawakkil, al-Kindi's star waned. There are various theories concerning this: some attribute al-Kindi's downfall to scholarly rivalries at the House of Wisdom.
Henry Corbin, an authority on Islamic studies, says that in 873, al-Kindi died "a lonely man", in Baghdad during the reign of al-Mu'tamid. After his death, al-Kindi's philosophical works fell into obscurity and many of them were lost to Islamic scholars and historians. Felix Klein-Franke suggests a number of reasons for this: aside from the militant orthodoxy of al-Mutawakkil, the Mongols destroyed countless libraries during their invasion. However, he says the most probable cause of this was that his writings never found popularity amongst subsequent influential philosophers such as al-Farabi and Avicenna, who overshadowed him. According to Ibn al-Nadim, al-Kindi wrote at least two hundred and sixty books, contributing to geometry and philosophy, physics. Although most of his books have been lost over the centuries, a few have survived in the form of Latin translations by Gerard of Cremona, others have been rediscovered in Arabic manuscripts, his greatest contribution to the development of Islamic philosophy was his efforts to make Greek thought both accessible and acceptable to a Muslim audience.
Al-Kindi carried out this mission from the House of Wisdom, an institute of translation and learning patronized by the Abbasid Caliphs, in Baghdad. As well as translating many important texts, much of what was to become standard Arabic philosophical vocabulary originated with al-Kindi. In his writings, one of al-Kindi's central concerns was to demonstrate the compatibility between philosophy and natural theology on the one hand, revealed or speculative theology on the other. Despite this, he did make clear that he believed revelation was a superior source of knowledge to
Afghanistan the Islamic Republic of Afghanistan, is a landlocked country located in South-Central Asia. Afghanistan is bordered by Pakistan in the south and east, its territory covers 652,000 square kilometers and much of it is covered by the Hindu Kush mountain range, which experiences cold winters. The north consists of fertile plains, while the south-west consists of deserts where temperatures can get hot in summers. Kabul serves as its largest city. Human habitation in Afghanistan dates back to the Middle Paleolithic Era, the country's strategic location along the Silk Road connected it to the cultures of the Middle East and other parts of Asia; the land has been home to various peoples and has witnessed numerous military campaigns, including those by Alexander the Great, Muslim Arabs, British and since 2001 by the United States with NATO-allied countries. It has been called "unconquerable" and nicknamed the "graveyard of empires"; the land served as the source from which the Kushans, Samanids, Ghaznavids, Khaljis, Hotaks and others have risen to form major empires.
The political history of the modern state of Afghanistan began with the Hotak and Durrani dynasties in the 18th century. In the late 19th century, Afghanistan became a buffer state in the "Great Game" between British India and the Russian Empire, its border with British India, the Durand Line, was formed in 1893 but it is not recognized by the Afghan government and it has led to strained relations with Pakistan since the latter's independence in 1947. Following the Third Anglo-Afghan War in 1919 the country was free of foreign influence becoming a monarchy under King Amanullah, until 50 years when Zahir Shah was overthrown and a republic was established. In 1978, after a second coup Afghanistan first became a socialist state and a Soviet Union protectorate; this evoked the Soviet–Afghan War in the 1980s against mujahideen rebels. By 1996 most of Afghanistan was captured by the Islamic fundamentalist group the Taliban, who ruled most of the country as a totalitarian regime for over five years.
The Taliban were forcibly removed by the NATO-led coalition, a new democratically-elected government political structure was formed, but they still control a significant portion of the country. Afghanistan is a unitary presidential Islamic republic with a population of 31 million composed of ethnic Pashtuns, Tajiks and Uzbeks, it is a member of the United Nations, the Organisation of Islamic Cooperation, the Group of 77, the Economic Cooperation Organization, the Non-Aligned Movement. Afghanistan's economy is the world's 108th largest, with a GDP of $64.08 billion. The name Afghānistān is believed to be as old as the ethnonym Afghan, documented in the 10th-century geography book Hudud ul-'alam; the root name "Afghan" was used in reference to a member of the ethnic Pashtuns, the suffix "-stan" means "place of" in Persian. Therefore, Afghanistan translates to land of the Afghans or, more in a historical sense, to land of the Pashtuns. However, the modern Constitution of Afghanistan states that "he word Afghan shall apply to every citizen of Afghanistan."
Excavations of prehistoric sites by Louis Dupree and others suggest that humans were living in what is now Afghanistan at least 50,000 years ago, that farming communities in the area were among the earliest in the world. An important site of early historical activities, many believe that Afghanistan compares to Egypt in terms of the historical value of its archaeological sites; the country sits at a unique nexus point where numerous civilizations have interacted and fought. It has been home to various peoples through the ages, among them the ancient Iranian peoples who established the dominant role of Indo-Iranian languages in the region. At multiple points, the land has been incorporated within large regional empires, among them the Achaemenid Empire, the Macedonian Empire, the Indian Maurya Empire, the Islamic Empire. Many empires and kingdoms have risen to power in Afghanistan, such as the Greco-Bactrians, Hephthalites, Kabul Shahis, Samanids, Ghurids, Kartids, Timurids and the Hotak and Durrani dynasties that marked the political origins of the modern state.
Archaeological exploration done in the 20th century suggests that the geographical area of Afghanistan has been connected by culture and trade with its neighbors to the east and north. Artifacts typical of the Paleolithic, Neolithic and Iron ages have been found in Afghanistan. Urban civilization is believed to have begun as early as 3000 BCE, the early city of Mundigak may have been a colony of the nearby Indus Valley Civilization. More recent findings established that the Indus Valley Civilisation stretched up towards modern-day Afghanistan, making the ancient civilisation today part of Pakistan and India. In more detail, it extended from what today is northwest Pakistan to northwest India and northeast Afghanistan. An Indus Valley site has been found on the Oxus River at Shortugai in northern Afghanistan. There are several smaller IVC colonies to be found in Afghanistan as well. After 2000 BCE, successive waves of semi-nomadic
Iraq the Republic of Iraq, is a country in Western Asia, bordered by Turkey to the north, Iran to the east, Kuwait to the southeast, Saudi Arabia to the south, Jordan to the southwest and Syria to the west. The capital, largest city, is Baghdad. Iraq is home to diverse ethnic groups including Arabs, Assyrians, Shabakis, Armenians, Mandeans and Kawliya. Around 95% of the country's 37 million citizens are Muslims, with Christianity, Yarsan and Mandeanism present; the official languages of Iraq are Kurdish. Iraq has a coastline measuring 58 km on the northern Persian Gulf and encompasses the Mesopotamian Alluvial Plain, the northwestern end of the Zagros mountain range and the eastern part of the Syrian Desert. Two major rivers, the Tigris and Euphrates, run south through Iraq and into the Shatt al-Arab near the Persian Gulf; these rivers provide Iraq with significant amounts of fertile land. The region between the Tigris and Euphrates rivers known as Mesopotamia, is referred to as the cradle of civilisation.
It was here that mankind first began to read, create laws and live in cities under an organised government—notably Uruk, from which "Iraq" is derived. The area has been home to successive civilisations since the 6th millennium BC. Iraq was the centre of the Akkadian, Sumerian and Babylonian empires, it was part of the Median, Hellenistic, Sassanid, Rashidun, Abbasid, Mongol, Safavid and Ottoman empires. The country today known as Iraq was a region of the Ottoman Empire until the partition of the Ottoman Empire in the 20th century, it was made up of three provinces, called vilayets in the Ottoman language: Mosul Vilayet, Baghdad Vilayet, Basra Vilayet. In April 1920 the British Mandate of Mesopotamia was created under the authority of the League of Nations. A British-backed monarchy joining these vilayets into one Kingdom was established in 1921 under Faisal I of Iraq; the Hashemite Kingdom of Iraq gained independence from the UK in 1932. In 1958, the monarchy was overthrown and the Iraqi Republic created.
Iraq was controlled by the Arab Socialist Ba'ath Party from 1968 until 2003. After an invasion by the United States and its allies in 2003, Saddam Hussein's Ba'ath Party was removed from power, multi-party parliamentary elections were held in 2005; the US presence in Iraq ended in 2011, but the Iraqi insurgency continued and intensified as fighters from the Syrian Civil War spilled into the country. Out of the insurgency came a destructive group calling itself ISIL, which took large parts of the north and west, it has since been defeated. Disputes over the sovereignty of Iraqi Kurdistan continue. A referendum about the full sovereignty of Iraqi Kurdistan was held on 25 September 2017. On 9 December 2017, then-Iraqi Prime Minister Haider al-Abadi declared victory over ISIL after the group lost its territory in Iraq. Iraq is a federal parliamentary republic consisting of one autonomous region; the country's official religion is Islam. Culturally, Iraq has a rich heritage and celebrates the achievements of its past in both pre-Islamic as well as post-Islamic times and is known for its poets.
Its painters and sculptors are among the best in the Arab world, some of them being world-class as well as producing fine handicrafts, including rugs and carpets. Iraq is a founding member of the UN as well as of the Arab League, OIC, Non-Aligned Movement and the IMF; the Arabic name العراق al-ʿIrāq has been in use since before the 6th century. There are several suggested origins for the name. One dates to the Sumerian city of Uruk and is thus of Sumerian origin, as Uruk was the Akkadian name for the Sumerian city of Urug, containing the Sumerian word for "city", UR. An Arabic folk etymology for the name is "well-watered. During the medieval period, there was a region called ʿIrāq ʿArabī for Lower Mesopotamia and ʿIrāq ʿAjamī, for the region now situated in Central and Western Iran; the term included the plain south of the Hamrin Mountains and did not include the northernmost and westernmost parts of the modern territory of Iraq. Prior to the middle of the 19th century, the term Eyraca Arabic was used to describe Iraq.
The term Sawad was used in early Islamic times for the region of the alluvial plain of the Tigris and Euphrates rivers, contrasting it with the arid Arabian desert. As an Arabic word, عراق means "hem", "shore", "bank", or "edge", so that the name by folk etymology came to be interpreted as "the escarpment", viz. at the south and east of the Jazira Plateau, which forms the northern and western edge of the "al-Iraq arabi" area. The Arabic pronunciation is. In English, it is either or, the American Heritage Dictionary, the Random House Dictionary; the pronunciation is heard in US media. In accordance with the 2005 Constitution, the official name of the state is the "Republic of Iraq". Between 65,000 BC and 35,000 BC northern Iraq was home to a Neanderthal culture, archaeological remains of which have been discovered at Shanidar Cave This same region is the location of a number of pre-Neolithic cemeteries, dating from 11,000 BC. Since 10,000 BC, Iraq was one of centres of a Caucasoid Neolithic culture (k
