Achievements of Hans Driesch (1867–1941), German embryologist and philosopher,are contemporarily viewed almost exclusively from their later metaphysicalphase of development, while his earlier scientific experimental researchesare not appreciated sufficiently enough. They consisted in highlighting thespecifically totipotential character of biological, and especially of embryological,processes what is still methodologically inspiring in many dimensions ofcontemporary biological investigations. The author postulates thus a deeperanalysis of Driesch’s scientific accomplishments and broader assessment oftheir actual significance in contemporary biology.
