Abstract
As we have illustrated in chapter 1, Thom, when commenting on Lévi-Bruhl, who had reflected on the spatial frameworks of primitive societies, states:This conception of a flexible and individual space-time, which will cease to be a universal frame valid for all men, clearly conflicts head on with the basic postulate of all modern science that there exists a universal space-time valid and isomorphic for all. It is without doubt this essential difference that Lévi-Bruhl had wished to signify in speaking of "pre-logical mentality" — unhappy words, for logic has in principle, nothing to do with the representation of space (Thom, 1983, p. 133).
