Creation — this is a common issue for both cultures. Natural science is interested in the origins of life, its emergence and differentiation and ability for self reproduction and variation. I want to mention here my friend Pier Luigi Luisi (now in Rome) who dedicated his scientific life to this fascinating question.¹ The humanities on the other side of the spectrum are interested in the origin of mind and psyche, of emotions and our ability for relationship. For a psychoanalytic approach both interests belong together, they appear as the two sides of the same fascinosum and of the same greater reality. I would like to call our different approaches to this one reality, by natural science or by humanities as "complementary" — following an idea of Wolfgang Pauli [1].
