The term ‘change’ occupies a remarkably heterogeneous position across the depth-psychology corpus, functioning simultaneously as ontological principle, clinical target, linguistic event, and soteriological aspiration. Hellmut Wilhelm’s exposition of the I Ching establishes the most philosophically ambitious register: change (I) names the very power through which heaven and earth remain generative, standing in dialectical tension with the ‘constant’ — the fixed hierarchical order that change paradoxically sustains. This cosmological polarity finds clinical descendants in Motivational Interviewing, where William Miller treats change as a process mediated by language, ambivalence, and motivational readiness, arguing that how clients talk about change is itself constitutive of whether it occurs. The transtheoretical model of Prochaska and DiClemente provides the developmental scaffolding within which MI operates, staging change across precontemplation, contemplation, preparation, and action. Pargament’s psychology of religion introduces a further axis — conservation versus transformation — in which change may be sought not as rupture but as the paradoxical means of preserving significance. Existential perspectives, represented by Yalom, interrogate the mechanism by which insight produces change, finding the causal chain opaque and suggesting that change may precede, rather than follow, self-knowledge. Across all these traditions, ambivalence toward change is recognized not as resistance but as a normative and even necessary moment in the transformation process.
