I cannot quite agree with your opinion about "individuation." It is not "individualization" but a conscious realization of everything the existence of an individual implies: his needs, his tasks, his duties, his responsibilities, etc. Individuation does not isolate, it connects. I never saw relationships thriving on unconsciousness.
— C. G. Jung
Jung is correcting a misreading that the tradition keeps generating because the misreading is so convenient. "Individualization" — the drawing inward, the self becoming more distinctly itself by contracting away from others — is close enough in sound to individuation that the confusion feels almost innocent. It is not innocent. The contraction is exactly what the soul wants when it has decided that connection is the source of damage. If I am sufficiently myself, separate, contained, I will not be wounded again. That is a recognizable logic, and it works well enough to be dangerous.
What Jung insists on instead is that individuation realizes everything the individual's existence *implies* — needs, tasks, duties, responsibilities. That word *implies* is doing quiet work: the individual is already folded into a relational field before the project of consciousness even begins. The work is to make explicit what was always latent. This is why he can say, without any sentimentality, that he never saw relationships thriving on unconsciousness. Not a moral prescription — an observation. The person who mistakes introversion for depth, withdrawal for integration, solitude for wholeness, is not moving toward individuation. They are moving away from the very field in which individuation becomes legible.
