In one of Luhmann's seminars that I (Rudolf Stichweh) attended, the slightly provocative question arose as to what he thought about genetic engineering. Luhmann pondered, as so often with a hint of theatricality, and then said "If the ability to learn is preserved ...!". In this exchange, the whole of Luhmann was present in nuce: the suspicion of technology, the morally exaggerated alternative, a Luhmannian evasive maneuver, ironic distance in an unanticipated answer.
