Before the rupture with the SI, Jorn, who sided with the SI against Nash, emphasised situlogy, "the transformative morphology of the unique."[4]
Howard Slater describes the break between the "Parisian" and the "Scandinavian" tendencies as amounting to "a conflict between a conceptual and an expressionist approach, or, to echo Jorn's two tendencies of situlogy, a conflict between the ludic and the analytical," and quotes the Drakabygget Declaration:
The Franco-Belgian Situationists base themselves on the same principles as Pascal, Descartes ... action precedes emotion. Emotion is a primary non-reflective intelligence: passionate thought/thinking passion. ... We do not always distinguish between theory and practice. We intend to produce our theories after the event. ... The French work exactly the other way round. They want everything straight before they start and everybody has to line up correctly.[5]
The Drakabygget Declaration was the founding document of the Second Situationist International, which appeared in the Situationist Times No. 2, 1962.
