Analytic philosophy
Overview
The dominant modern tradition in English. It works by the rigorous logical analysis of language, arguments and concepts.
Analytic philosophy, begun by Frege, Russell and Moore and long strongest in English-speaking universities, is the habit of taking a sentence apart until the claim is precise enough to fail. Russell wants the grammar of a sentence to stop posing as its logic. A phrase can look like a name and refer to nothing. If you do not notice, you will argue about a thing that was only a form of words.

Wittgenstein first treats meaning as a picture: a sentence shows a possible arrangement of the world. He later treats that as too narrow. Meaning, in the later work, is a matter of what people do with the words in a form of life. The two stages disagree. The later work presses that a foggy noun has to be walked back to a use. The Vienna Circle, drawing on the early work, added a sharper test: if nobody can say what would count against a sentence, it may not be saying anything.
The school can become a local dialect, proud of its tools and deaf outside them. At its best it is a public service. It slows a room down. It asks which word is doing the work, what the argument actually concluded and what fact would make the speaker take it back. That last question is already a lesson elsewhere on this mountain. The tradition is where the habit was sharpened.
