Samenvatting

A rational choice of partner would end in abandonment as soon as even a slightly 'better ' partner appears. As a result, nothing could be built together, while collaboration is exactly what people are good at, for better or for worse. Virtues such as love and loyalty and feelings such as passion and jealousy play a much more important and evolutionarily entrenched role than rationality. When trying to understand our world in exceptional crisis situations, we have to keep this in mind. However, this turns out to be extremely complicated and, paradoxically, requires well-implemented rationality.
