Abstract

Rudolf Carnap’s Der logische
Aufbau der Welt famously builds a
construction of the world starting
from an “autopsychological” basis
involving structures of phenomenal
similarity. In a letter to Moritz Schlick
in 1927, Carnap suggested that he
might write a second volume of the
Aufbau that starts from a physical
basis instead. Carnap never carried
out this project, however. I will argue
that the core materials for Carnap’s
second Aufbau (a structuralist
analysis of physics and a definitionbased
reduction of everything else
to this structure) can be found in the
work of David Lewis, and that this
second Carnap-Lewis Aufbau might
have avoided many of the objections
directed at the first.
