The previous Essay traced some epistemological stages along Driesch's road to neo-vitalism, a transgression that is singular in view of his previous merits (and recognition) as an experimental embryologist. Here we shall review his experimental work between the teleo-mechanistic Analytische Theorie der organischen Entwicklung of 1894 (see Essay 11) and the end of his career as an active embryologist, which came shortly after his neo-vitalistic Gifford Lectures of 1908.
