This recording explores the relationship between the neurophysiological basis of thought and its components independent of this basis. It rejects psychophysical parallelism in favor of a series of contingencies. The text criticizes causalism as a 'scientific superstition' and refers to Husserl's polemic against psychologism. The key argument is that thought becomes logical when, due to increasing specific contingency, it opens up to the incoming logos, thereby ceasing to be a mere causal link. The growing complexity of mutual reactions weakens the character of so-called causality, which is in reality just a set of reactions. The more complex this reaction system becomes, the less determined it is and the more open it is to the 'attractiveness of the logos.' This attractiveness lies in establishing norms that differ from causal relationships. The culmination of this evolution of reactivity is thought and reflection, where logos fully reveals itself as a norm-creating principle, not as chance or an external guiding force.
