Optimism should have a separate page that focuses on the philosophical idea of optimism and distinguishes the philosophical view from "positive thinking" and other everyday uses of the word.
Philosophy of social science, has some okay points but requires elaboration on Wittgenstein and Winch, perhaps other linguistic critiques, whether logical positivist or postmodernist.
Exchange value needs to be redone, it shouldn't be under 'Marxist theory'- although it's an important component of Marxist theory it's also vital for all economics. That said the article's weight on Marx is also absurd.
Socratic dialogues could do with some tidying and clarification. See the talk page for one suggested change.
Problem of universals: The introductory definition is (perhaps) fixed. But, the article is poor. Check out the German version.
Teleology: the article is shallow and inconsistent.
Existentialism: the quality of this article varies wildly and is in desperate need of expert attention.
Analytic philosophy This is a very major topic, but still has several sections which are stubs, and several topics which are not covered.
Lifeworld A philosophical concept that seems to have fallen exclusively into the hands of the sociologists. Could use some attention; it's a major and complex issue in phenomenology.
Perception Needs the attention of philosophically minded Wikipedians. This is only the start of an overhaul of perception and related articles.
Percy Grainger (1882–1961) was an Australian-born composer, arranger and pianist who played a prominent role in the revival of interest in British folk music in the early 20th century. Grainger left Australia in 1895 to study at the Hoch Conservatory in Frankfurt. Between 1901 and 1914 he was based in London, where he established himself first as a society pianist and later as a concert performer, composer and collector of original folk melodies. He met many of the significant figures in European music, forming friendships with Frederick Delius and Edvard Grieg, and became a champion of Nordic music and culture. In 1914, Grainger moved to the United States, where he took citizenship in 1918. He experimented with music machines that he hoped would supersede human interpretation. Although much of his work was experimental and unusual, the piece with which he is most generally associated is his piano arrangement of the folk-dance tune "Country Gardens". This glass negative of Grainger was taken at some point around 1915–1920.Photograph credit: Bain News Service; restored by Adam Cuerden and MyCatIsAChonk
