The author discusses humanistic interpretation as one of the basic methodol
ogies in social sciences. This interpretation is one form of scientific exp
lanation and understanding of human action. It is based on the nomological,
idealized assumption of rationality of the agent and on the reconstruction
of practical reasoning. The method of humanistic interpretation confronts
critically the pre-conceptual understanding, which is based on a pure proje
ction of the self in the deliberation and action of the agent.
