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.
Machado de Assis (1839–1908) was a Brazilian novelist, poet, playwright and short-story writer, widely regarded as the greatest writer of Brazilian literature. In 1897, he founded and became the first president of the Brazilian Academy of Letters. He was multilingual, having taught himself French, English, German and Greek later in life. Machado's work shaped the realist movement in Brazil and the birth of the Brazilian republic made Machado become more critical and an observer of the Brazilian society of his time. Generally considered to be Machado's greatest works are Dom Casmurro (1899), Memórias Póstumas de Brás Cubas (Posthumous Memoirs of Brás Cubas, also translated as Epitaph of a Small Winner) and Quincas Borba (also known in English as Philosopher or Dog?). In 1893, he published "A Missa do Galo" ("Midnight Mass"), often considered to be the greatest short story in Brazilian literature. This photograph of Machado was taken by the Brazilian photographer Marc Ferrez in 1890.Photograph credit: Marc Ferrez; restored by Adam Cuerden
