Wheaton College President Philip Ryken said "It would be hard to think of anyone who has had a greater impact on Christian higher education than Arthur Holmes." Holmes died in Wheaton, Illinois, on October 8, 2011, at age 87.

paragraph_text: Avicenna was a devout Muslim and sought to reconcile rational philosophy with Islamic theology. His aim was to prove the existence of God and His creation of the world scientifically and through reason and logic. Avicenna's views on Islamic theology (and philosophy) were enormously influential, forming part of the core of the curriculum at Islamic religious schools until the 19th century. Avicenna wrote a number of short treatises dealing with Islamic theology. These included treatises on the prophets (whom he viewed as "inspired philosophers"), and also on various scientific and philosophical interpretations of the Quran, such as how Quranic cosmology corresponds to his own philosophical system. In general these treatises linked his philosophical writings to Islamic religious ideas; for example, the body's afterlife.

paragraph_text: One of the common definitions for "Islamic philosophy" is "the style of philosophy produced within the framework of Islamic culture." Islamic philosophy, in this definition is neither necessarily concerned with religious issues, nor is exclusively produced by Muslims. The Persian scholar Ibn Sina (Avicenna) (980–1037) had more than 450 books attributed to him. His writings were concerned with various subjects, most notably philosophy and medicine. His medical textbook The Canon of Medicine was used as the standard text in European universities for centuries. He also wrote The Book of Healing, an influential scientific and philosophical encyclopedia.

paragraph_text: Islamic political philosophy, was, indeed, rooted in the very sources of Islam—i.e., the Qur'an and the Sunnah, the words and practices of Muhammad—thus making it essentially theocratic. However, in the Western thought, it is generally supposed that it was a specific area peculiar merely to the great philosophers of Islam: al-Kindi (Alkindus), al-Farabi (Abunaser), İbn Sina (Avicenna), Ibn Bajjah (Avempace), Ibn Rushd (Averroes), and Ibn Khaldun. The political conceptions of Islam such as kudrah (power), sultan, ummah, cemaa (obligation)-and even the "core" terms of the Qur'an—i.e., ibadah (worship), din (religion), rab (master) and ilah (deity)—is taken as the basis of an analysis. Hence, not only the ideas of the Muslim political philosophers but also many other jurists and ulama posed political ideas and theories. For example, the ideas of the Khawarij in the very early years of Islamic history on Khilafa and Ummah, or that of Shia Islam on the concept of Imamah are considered proofs of political thought. The clashes between the Ehl-i Sunna and Shia in the 7th and 8th centuries had a genuine political character.

paragraph_text: Queen Zixi of Ix, or The Story of the Magic Cloak, is a children's book written by L. Frank Baum and illustrated by Frederick Richardson. It was originally serialized in the early 20th-century American children's magazine "St. Nicholas" from November 1904 to October 1905, and was published in book form later in 1905 by The Century Company. The events of the book alternate between Noland and Ix, two neighboring regions to the Land of Oz, and Baum himself commented this was the best book he had written. In a letter to his eldest son, Frank Joslyn Baum, he said it was "nearer to the "old-fashioned" fairy tale than anything I have yet accomplished," and in many respects, it adheres more closely to the fairy tale structure than the Oz books.

paragraph_text: The term "Islamic education" means education in the light of Islam itself, which is rooted in the teachings of the Quran - holy book of Muslims. Islamic education and Muslim education are not the same. Because Islamic education has epistemological integration which is founded on Tawhid - Oneness or monotheism. For details Read "A Qur’anic Methodology for Integrating Knowledge and Education: Implications for Malaysia’s Islamic Education Strategy" written Tareq M Zayed  and "Knowledge of Shariah and Knowledge to Manage ‘Self’ and ‘System’: Integration of Islamic Epistemology with the Knowledge and Education" authored by Tareq M Zayed

paragraph_text: Early Islamic philosophy and Islamic metaphysics, imbued as it is with Islamic theology, distinguishes more clearly than Aristotelianism between essence and existence. Whereas existence is the domain of the contingent and the accidental, essence endures within a being beyond the accidental. The philosophy of Ibn Sīnā, particularly that part relating to metaphysics, owes much to al-Farabi. The search for a definitive Islamic philosophy separate from Occasionalism can be seen in what is left of his work.

paragraph_text: Elisabeth Camp is an Associate Professor of Philosophy at Rutgers University. Camp's work has focused on forms of thought and speech that do not fit standard propositional models. She has written extensively about figurative speech such as sarcasm and metaphor, arguing that these forms of speech force listeners to reconsider their standard methods of delineating the difference between what is meant and what is said.

paragraph_text: Sayyid Abul Ala Maududi was an important early twentieth-century figure in the Islamic revival in India, and then after independence from Britain, in Pakistan. Trained as a lawyer he chose the profession of journalism, and wrote about contemporary issues and most importantly about Islam and Islamic law. Maududi founded the Jamaat-e-Islami party in 1941 and remained its leader until 1972. However, Maududi had much more impact through his writing than through his political organising. His extremely influential books (translated into many languages) placed Islam in a modern context, and influenced not only conservative ulema but liberal modernizer Islamists such as al-Faruqi, whose "Islamization of Knowledge" carried forward some of Maududi's key principles.

paragraph_text: German philosophers have helped shape western philosophy from as early as the Middle Ages (Albertus Magnus). Later, Leibniz (17th century) and most importantly Kant played central roles in the history of philosophy. Kantianism inspired the work of Schopenhauer and Nietzsche as well as German idealism defended by Fichte and Hegel. Engels helped develop communist theory in the second half of the 19th century while Heidegger and Gadamer pursued the tradition of German philosophy in the 20th century. A number of German intellectuals were also influential in sociology, most notably Adorno, Habermas, Horkheimer, Luhmann, Simmel, Tönnies, and Weber. The University of Berlin founded in 1810 by linguist and philosopher Wilhelm von Humboldt served as an influential model for a number of modern western universities.
