Editing German philosophy (section)

====Frege, Wittgenstein and the Vienna Circle====
In the late 19th century, the predicate logic of [[Gottlob Frege]] (1848–1925) made the first substantial advance over [[Aristotelian logic]] since its inception in Ancient Greece. This was the beginning of [[analytic philosophy]]. In the early part of the 20th century, a group of German and Austrian philosophers and scientists formed the [[Vienna Circle]] to promote scientific thought over Hegelian system-building, which they saw as a bad influence on intellectual thought. The group considered themselves [[logical positivists]] because they believed all knowledge is either derived through experience or arrived at through analytic statements, and they adopted the predicate logic of Frege, as well as the early work of [[Ludwig Wittgenstein]] (1889–1951) as foundations to their work.
