This first volume of The Collected Works of Rudolf Carnap includes Carnap’s published writings from 1921 when he submitted his dissertation Der Raum (Space) in Jena to Bruno Bauch to 1926 the year he completed his habilitation in Vienna under Moritz Schlick. It thereby documents Carnap’s early writings during his formative years that culminated in his first major publication Der logische Aufbau der Welt (The Logical Structure of the World) which appeared in 1928 and will be included in the second volume. Fourteen volumes are planned in total. In his foreword Richard Creath, the general editor, states that the series will include “all of the books and papers Carnap authorized for publication in his lifetime.” (viii)
