Available for the first time in 20 years, here are two important works from the 1920s by the best-known representative of the Vienna Circle. In The Logical Structure of the World, Carnap adopts the position of “methodological solipsism” and shows that it is possible to describe the world from the immediate data of experience. In his Pseudoproblems in Philosophy, he asserts that many philosophical problems are meaningless.
