The nascent state is a psychological process of destructuration-reorganization where the individual becomes capable of merging with other persons and creating a new collectivity with a very high degree of solidarity.

Falling in love is the nascent state of a collective movement formed of two people only. According to Francesco Alberoni, the phenomenology of falling in love is the same for young people and adults, for men and women and for homosexuals and heterosexuals: this is because the structure of the nascent state is always the same.
