Nexus stands for an affective prelogical knot common to a large number of individuals in a particular community. It is a knot in the sense that it “associates and connects a series of attitudes” and is affectively prelogical because it can “instantly operate a rejection or adhesion” (“which leaves no room for reasoning or afterthought”). Its anchoring in reality is achieved by issuing clear opinions, firm positions or mobilizing slogans. Ultimately, these categories of individuals only have to manifest themselves for or against the produced assessment. The maximum effect is reached in crisis situations, “with the occurrence of real or imaginary abnormal events in the social life (conflicts, collective threats, etc.).”
