Crystallization enters the depth-psychology corpus through two distinct but ultimately convergent registers. The first and philosophically most elaborate is Simondon’s treatment in his theory of individuation, where crystallization serves as the paradigmatic model for understanding how an individual emerges from a pre-individual, metastable field. For Simondon, the crystal is not merely a physical example but an ontological prototype: the seed-germ introduces structural information into an energetically charged, amorphous milieu, and the resulting growth is neither purely exterior nor interior — it is a becoming that constitutes the very being of the individual. This model resists hylomorphic assumptions by foregrounding the relational, processual, and historically contingent character of individuation. The second register is psychological and imaginal. William James employs crystallization as a vivid metaphor for the fixing of temperamental character — the healthy-minded soul ‘set’ in its optimism as if in a mother liquid. Edinger and the alchemical tradition invoke the precipitation of golden crystals as an image of consciousness emerging from the coniunctio. Hillman’s critique identifies dogmatic crystallization as a pathological arrest of psychic fluidity. Tozzi explicitly opposes the crystallization of fixed positions to the transformative openness demanded by authentic movement. Across these voices, the term carries a double valence: crystallization as the necessary, information-bearing structuration of individuality, and crystallization as the dangerous rigidity that arrests psychological becoming.
most often in crystallization germs are deposited from the exterior. Thus, there is a historical aspect
Simondon establishes that crystallization cannot be reduced to energetic conditions alone; the structural germ introduced from outside confers a historical, contingent dimension on all physical individuation.

the dissymmetry continues throughout the genesis; whence results the nature of the indefiniteness of the crystal’s growth; becoming is not opposed to being; it is the constitutive relation of being qua individual.
Simondon argues that crystalline growth is the paradigmatic case demonstrating that becoming is constitutive of, not opposed to, individual being.

the crystal has grown, it has at least partially incorporated certain amounts of substance that constituted the support of the potential energy of the metastable state while they were amorphous.
Simondon demonstrates that the crystal progressively internalizes what was previously exterior potential energy, collapsing the distinction between inside and outside as individuation proceeds.

the genesis of the crystalline form closest to the amorphous state could be assimilated to any passage whatsoever from one allotropic crystalline form to another.
Simondon clarifies the ontological difficulty posed by crystallization: the absolute genesis of individuation from the amorphous is harder to define than a relative transition between already-structured states.

The crystalline milieu is a triply periodic milieu whose period is defined by the lattice parameters.
Simondon elaborates crystallization as the production of a periodic, self-replicating structural milieu in which the limit is constitutive rather than externally imposed.

the power of spontaneous crystal ization that this liquid presents (defined by the number of crystalline germs that spontaneously appear in a set time within a given volume of liquid)
Simondon introduces the quantitative concept of spontaneous crystallization power as one of the two factors governing the transition from metastable to crystalline state.

the tendency to see things optimistically is like a water of crystallization in which the individual’s character is set.
James deploys crystallization as a precise metaphor for the fixing of temperamental optimism into the settled substrate of religious character.

The individual is not substance, for substance is not limited by anything other than itself … Every rigorous substantialism excludes the notion of the individual
Simondon uses the crystal as a counter-example to substantialist ontology, arguing that the individual is a limitedly growing being rather than a self-enclosed substance.

to perception what syn-crystallization is to the crystallization of a single chemical type.
Simondon extends the crystallization analogy to consciousness, proposing that perception relates to concepts as syn-crystallization does to single-type crystallization, underscoring a unified ontogenetic logic.

the dogmatic crystallization of our religious culture demonized the daimons.
Hillman employs crystallization negatively, as the pathological rigidification of religious doctrine that suppressed the polytheistic middle realm and demonized the imagination.

Individuation has not been able to be adequately thought and described because only a single form of equilibrium was known, namely stable equilibrium; what was unknown was precisely metastable equilibrium
Simondon situates the failure to understand crystallization-as-individuation in the exclusive reliance on stable equilibrium, which cannot account for becoming.
