Abstract

The aim of the paper is to investigate, from the point of view of philosophy of science and philosophy of social science, the turn in the ape language project (ALP) as accomplished in the works of Sue Savage-Rumbaugh and her collaborators. In this project a highly interesting turn from the orientation of research on natural sciences to that on humanities took place. We shall analyze all the relevant works of Savage-Rumbaugh from the point of view of the three central levels of ALP: its scientific, metascientific and methodological levels.
