Within the depth-psychological corpus, 'weak' operates along several distinct but interrelated axes, none of which reduces simply to deficit or pathology. In the I Ching commentarial tradition — represented by Wang Bi, Wilhelm, and the Taoist interpreters — the 'soft and weak' (yin lines) constitute an essential cosmological principle whose proper positioning, not elimination, generates favorable outcomes; weakness is thus rehabilitated as a mode of rightful compliance and median restraint. Hillman's archetypal psychology reframes the 'weak ego' not as a clinical failure but as the human condition itself — mortality's signature, the wound that carries a blessing — and warns that compensatory ego-strengthening destroys something sacred in the same stroke. The Stoic akrasia literature (Inwood) treats 'weak will' in its strict sense as a genuine philosophical crisis: any psychology that tightly couples practical judgment to intentional action must reckon with the agent who acts against his own moral verdict. Von Franz distinguishes the 'asthenic type' whose psychic constitution cannot sustain direct confrontation with the core problem, contrasting it with the 'strong type' whose dreams drive directly to a healing crisis. Across these registers — cosmological, archetypal, ethical, typological — weakness emerges as a term whose evaluation depends entirely on whether it occupies its proper place within a larger ordering structure.
Organ inferiority is indeed a ground of the weak ego, but the 'weak ego' is merely pathology's way of stating that the ego is only human.
Hillman reframes the 'weak ego' as an archetypal statement of human mortality rather than a remediable clinical deficit, arguing that attempts at ego-compensation without attending to the wound's blessing are both naive and irreligious.

weak will in the strict sense does. Why? Any psychology of action which postulates a close linkage between what may in general terms be called 'practical decisions' and the causes of actions… will have difficulties in the analysis of strictly construed cases of weak will.
Inwood argues that akrasia in its strict sense — acting against one's own moral judgment — poses a structural crisis for any psychology that tightly couples practical decision to action-causation, including Stoic psychology.

the essential requirement of Ferrying Complete lies in the soft and weak obtaining a central position. If one were to misconstrue Ferrying Complete to mean perfect security, its Dao would come to an end.
Wang Bi's commentary establishes that the soft and weak principle is not subordinate but structurally necessary: only when weakness occupies the median position does the hexagram's favorable potential actualize.

In the asthenic type, the dreams themselves do not push the problem… 'the confrontation would not be possible. The unconscious knows better than I do and says that this problem cannot be touched.'
Von Franz identifies a constitutional 'asthenic type' whose psychic weakness is recognized and respected by the unconscious itself, which withholds direct confrontation to prevent psychic explosion.

In the asthenic type, the dreams themselves do not push the problem… 'the confrontation would not be possible. The unconscious knows better than I do and says that this problem cannot be touched. It is too hot; it would explode the person.'
Parallel to the foregoing, this passage from von Franz's expanded Puer Aeternus text reiterates that the unconscious itself calibrates therapeutic pressure to the patient's psychic constitution, withholding confrontation from the constitutionally weak.

The soft and weak must not be increased completely, and the hard and strong must not be completely whittled away.
Wang Bi articulates a principle of structural balance in which neither weakness nor strength should be allowed to dominate absolutely, each requiring its counterpart to maintain the hexagram's integrity.

a humble ruler (a weak line in the fifth place) who reveres a strong sage (a strong line above), as in hexagrams 14, 26, 27, 50. This is naturally very favorable.
Wilhelm's commentary demonstrates that a weak ruling line deferring to a strong sage above is not a sign of failure but of auspicious humility within the hexagram's hierarchical logic.

those critics who have seen Chrysippus' position as at most a verbal refinement of Zeno's must be right.
Inwood establishes the Stoic theoretical background for weak will by clarifying that the difference between Zeno's and Chrysippus's accounts of passion is one of emphasis rather than radical revision, setting up the deeper structural problem akrasia poses.

To simulate habituation, I would apply repeated, weak electrical pulses to this neural pathway.
In a neuroscientific rather than psychological register, Kandel employs 'weak' as a technical descriptor of stimulus intensity in modeling habituation, illustrating how the term migrates into somatic science as a quantitative rather than evaluative category.

In modeling sensitization I applied a weak stimulus to the same neural pathway leading to cell R2 that I had used in my earlier experiments on habituation.
Kandel again uses 'weak' as a quantitative stimulus parameter in sensitization experiments, offering a neurobiological counterpoint to depth-psychological uses of weakness as a qualitative or moral category.

he counsels the reputable Corinthians to treat their weaker brothers and sisters with special honor.
Thielman's reading of Paul introduces a socio-theological usage of weakness as a category of marginalization within the ecclesial body requiring compensatory honor, distinct from the intrapsychic or cosmological senses dominant elsewhere in the corpus.
