Most of the information about Pythagoras was written down centuries after he lived, so very little reliable information is known about him.

The scientific study of language is called linguistics. Questions concerning the philosophy of language, such as whether words can represent experience, have been debated since Gorgias and Plato in Ancient Greece. Thinkers such as Rousseau have argued that language originated from emotions while others like Kant have held that it originated from rational and logical thought. 20th-century philosophers such as Wittgenstein argued that philosophy is really the study of language. Major figures in linguistics include Ferdinand de Saussure and Noam Chomsky. - Mehmed IV (Ottoman Turkish: "Memed-i rbi"; Modern Turkish: "IV. Mehmet"; also known as "Avc Mehmed", Mehmed the Hunter; January 2, 1642 January 6, 1693) was the Sultan of the Ottoman Empire from 1648 to 1687.

While the first and last years of his reign were characterized by military defeat and political instability, during his middle years he oversaw the revival of the empire's fortunes associated with the Koprulu era.

To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries. - The Treaty of Karlowitz was signed on 26 January 1699 in Sremski Karlovci, in modern-day Serbia, concluding the Austro-Ottoman War of 168397 in which the Ottoman side had been defeated at the Battle of Zenta.

The term was probably coined by Pythagoras (c. 570 c. 495 BC). Philosophical methods include questioning, critical discussion, rational argument and systematic presentation. Classic philosophical questions include: Is it possible to know anything and to prove it? What is most real? However, philosophers might also pose more practical and concrete questions such as: Is there a best way to live? Is it better to be just or unjust (if one can get away with it)? Do humans have free will? - The Austrian Empire (modern spelling "") was an empire in Central Europe created out of the realms of the Habsburgs by proclamation in 1804.
