7. Rudolf Carnap

7.1 Early Days

Though Carnap is closely associated with the Vienna Circle and Logical Positivism, for the purposes of this narrative important and enduring aspects of Carnap's philosophical outlook predated his involvement in the circle, and can therefore be presented before we consider the influences of his time in Vienna.

Rudolf Carnap's conceived of himself as progressing Russell's conception of a scientific philosophy whose method was mathematical logic.

His importance is in the efforts he made to articulate methods for philosophy conceived in this way, one purpose of which was to pass on the benefits of these methods to science.

His first substantial work was the application of formal methods in an attempted phenomenological reduction and resulted in the work with which his name has since been most closely associated ever since, Der Logicshe Aufbau Der Welt [2].

7.2 Carnap and The Vienna Circle

The Vienna Circle provided a highly stimulating environment in which Carnap's ideas developed.

When Carnap's association with the Vienna Circle began he already had a draft of his aufbau which is one of the works which were read and discussed by the circle. Another important and more broadly influential work discussed by the circle was Wittgenstein's Tractatus Logico Philosophicus [12].

Among the many sources of influence during this period three are of particular significance for our narrative:

Of these the first three are significant for Carnap's next major innovation, which is the conception of philosophical analysis articulated in The Logical Syntax of Language [3,5] (and Philosophy and Logical Syntax [4]). Tarski's relevance is greater to Carnap's later work on semantics.
