François-Marie Arouet (French: [fʁɑ̃.swa ma.ʁi aʁ.wɛ]; 21 November 1694 – 30 May 1778), known by his nom de plume Voltaire (pronounced: [vɔl.tɛːʁ]), was a French Enlightenment writer, historian and philosopher famous for his wit, his attacks on the established Catholic Church, and his advocacy of freedom of religion, freedom of expression, and separation of church and state. Voltaire was a versatile writer, producing works in almost every literary form, including plays, poems, novels, essays, and historical and scientific works. He wrote more than 20,000 letters and more than 2,000 books and pamphlets. He was an outspoken advocate, despite the risk this placed him in under the strict censorship laws of the time. As a satirical polemicist, he frequently made use of his works to criticize intolerance, religious dogma, and the French institutions of his day. Biography

Socrates (/ˈsɒkrətiːz/; Greek: Σωκράτης, Ancient Greek pronunciation: [sɔːkrátɛːs], Sōkrátēs; 470/469 BC – 399 BC) was a classical Greek (Athenian) philosopher. Credited as one of the founders of Western philosophy, he is an enigmatic figure known chiefly through the accounts of later classical writers, especially the writings of his students Plato and Xenophon and the plays of his contemporary Aristophanes. Many would claim that Plato's dialogues are the most comprehensive accounts of Socrates to survive from antiquity. Through his portrayal in Plato's dialogues, Socrates has become renowned for his contribution to the field of ethics, and it is this Platonic Socrates who lends his name to the concepts of Socratic irony and the Socratic method, or elenchus.
Islamic philosophy Islamic philosophy or Arabic philosophy is the systematic investigation of problems connected with life, the universe, ethics, society, and so on as conducted in the Muslim world. Not all Islamic philosophers have been Muslims. Christians such as Yahya ibn Adi and Jews such as Maimonides have made important contributions to the Islamic philosophical tradition, and others, such as Ibn al-Rawandi and Muhammad ibn Zakariya al-Razi, used philosophy to attack Islam.
Al-Kindi Abu Yūsuf Yaʻqūb ibn ʼIsḥāq aṣ-Ṣabbāḥ al-Kindī (Arabic: أبو يوسف يعقوب بن إسحاق الصبّاح الكندي, Latin: Alkindus) (c. 801–873 CE), known as "the Philosopher of the Arabs", was an Iraqi Muslim Arab philosopher, mathematician, physician, and musician. Al-Kindi was the first of the Muslim peripatetic philosophers, and is unanimously hailed as the "father of Islamic or Arabic philosophy" for his synthesis, adaptation and promotion of Greek and Hellenistic philosophy in the Muslim world. Al-Kindi was a descendant of the Kinda tribe. He was born and educated in Basra, before going to pursue further studies in Baghdad. Al-Kindi became a prominent figure in the House of Wisdom, and a number of Abbasid Caliphs appointed him to oversee the translation of Greek scientific and philosophical texts into the Arabic language.
First published Fri Dec 1, 2006; substantive revision Wed Jan 26, 2011 Abu Yusuf Ya‘qub ibn Ishaq Al-Kindi (ca. 800–870 CE) was the first self-identified philosopher in the Arabic tradition. He worked with a group of translators who rendered works of Aristotle, the Neoplatonists, and Greek mathematicians and scientists into Arabic. Al-Kindi's own treatises, many of them epistles addressed to members of the caliphal family, depended heavily on these translations, which included the famous Theology of Aristotle and Book of Causes, Arabic versions of works by Plotinus and Proclus.

Ludwig Josef Johann Wittgenstein (26 April 1889 – 29 April 1951) was an Austrian-British philosopher who worked primarily in logic, the philosophy of mathematics, the philosophy of mind, and the philosophy of language. From 1939–1947, Wittgenstein taught at the University of Cambridge. During his lifetime he published just one slim book, the 75-page Tractatus Logico-Philosophicus (1921), one article, one book review and a children's dictionary. His voluminous manuscripts were edited and published posthumously. Philosophical Investigations appeared as a book in 1953 and by the end of the century it was considered an important modern classic. Philosopher Bertrand Russell described Wittgenstein as "the most perfect example I have ever known of genius as traditionally conceived; passionate, profound, intense, and dominating". Born in Vienna into one of Europe's richest families, he inherited a large fortune from his father in 1913.
Philosophical Investigations Philosophical Investigations (Philosophische Untersuchungen) is a highly influential work by the 20th-century philosopher Ludwig Wittgenstein. In it, Wittgenstein discusses numerous problems and puzzles in the fields of semantics, logic, philosophy of mathematics, philosophy of psychology, philosophy of action, and the philosophy of mind. He puts forth the view that conceptual confusions surrounding language use are at the root of most philosophical problems, contradicting or discarding much of what he argued in his earlier work, the Tractatus Logico-Philosophicus. He alleges that the problems are traceable to a set of related assumptions about the nature of language, which themselves presuppose a particular conception of the essence of language.
