The crystalline milieu is a periodic milieu. To know the crystalline milieu completely, all we need to know is the content of the crystalline elementary lattice, i.e. the position of the different atoms
Simondon establishes the crystalline milieu as a triply-periodic structure whose complete intelligibility resides in its elementary lattice, making it the paradigmatic model for how individuation propagates form through an amorphous medium.
