Within the depth-psychology corpus, 'brother' functions across several distinct registers that illuminate its psychological density. At the most concrete ethnolinguistic level, Benveniste's comparative work reveals that the Indo-European term *bhrāter carried not merely biological but classificatory and social weight, a weight so charged that Christian usage of frater—'brother in religion'—displaced it in Ibero-Romance kinship vocabulary entirely, forcing the coinage of germanus for natural siblinghood. This semantic instability already signals the psychological ambivalence the term harbors. In mythological and fairy-tale amplification, von Franz and McGilchrist present the brother pair as the primary dramaturgy of polar forces: the elder and younger brother in Warrau myth enact contamination and discernment, while the Haudenosaunee figures of Flint and He Grasps The Sky With Both Hands stage cosmic creativity versus destructive imitation, with the crucial insight that separation from the brother is itself the condition of wrongdoing. Fromm transposes the figure into an ethics of 'brotherly love' as the widest extension of eros—union with all humanity through penetration to the human core. Radin's Trickster material uses 'brother' as the vocative of appeal across species boundaries, suggesting the term functions as a fundamental marker of kinship-in-need. Taken together, these treatments position 'brother' as the axis where biological bond, social classification, shadow dynamics, and universal solidarity converge.
in the course of Christianization, frater, like soror, had taken on an exclusively religious sense, 'brother and sister in religion.' It was therefore necessary to coin a new term for natural kinships
Benveniste demonstrates that the term 'brother' is culturally unstable: its semantic field can be commandeered by a new classificatory system (religious kinship), forcing the biological concept into a different lexeme.

it is only when Flint is cut off from his brother that he does wrong. So He Grasps The Sky With Both Hands rescinds the act of separating himself off from the evil, and returns to his brother
McGilchrist uses the Haudenosaunee myth to argue that the brother-pair represents complementary cosmic principles whose severance—not their opposition—produces evil, making reconnection the redemptive act.

A parallel passage confirming the same mythological argument: the brother figure emblematizes the danger of splitting creative from imitative principles and the necessity of their reunion.

In brotherly love there is the experience of union with all men, of human solidarity, human at-onement. Brotherly love is based on the experience that we all are one.
Fromm elevates the brother-concept beyond kinship into the widest ethical register, defining brotherly love as the experiential foundation of universal human solidarity.

the elder brother in particular drank a lot, but the younger brother rather nervously refused to drink anything and felt suspicious and had the feeling that they had fallen among the Warekki
Von Franz deploys the elder/younger brother contrast as a vehicle for the shadow dynamic: the elder's unconscious absorption into the demonic collective versus the younger's wary discriminating consciousness.

The systems which have been studied outside the Indo-European world sometimes make use of identical terms for degrees of relationship which are distinguished in modern western societies: those, for instance, for 'brother' and 'cousin'
Benveniste shows that kinship classifications conflating 'brother' and 'cousin' reveal how the term is a social-structural variable rather than a fixed biological descriptor.

one who is an elder brother must be able to teach his younger brother. If a father cannot lay down the law to his son and an elder brother cannot teach his younger brother, then the relationship between father and son and elder and younger brother loses all value.
Zhuangzi's Confucian framing presents the elder-brother role as a normative pedagogical and moral office whose failure collapses the entire relational order.

'Brother, you have always been here in these waters, perhaps you could tell me where the shore is, for I cannot find it.' 'Alas, my brother, never, no, never, do I get anywhere near the shore.'
Radin's Trickster myth uses 'brother' as the cross-species vocative of appeal and solidarity in extremis, marking it as the primary address-form when existential guidance is sought.

Skt. bhrātr̥vya- 'brother's son, later cousin' > 'enemy' may lead us not to question the ancient values of the suffix, but to interpret the deviation which it has undergone by reference in each case to the particular system
Benveniste traces the semantic drift of the 'brother' derivative into 'enemy,' illustrating how structural position within the kinship system can invert the term's affective valence.

This obliteration was due to the creation of adelphḗ 'sister', and this in its turn was produced by the transformation of the term for 'brother.'
Benveniste demonstrates that the restructuring of the Greek 'brother' term triggered a cascade of lexical displacement across the entire kinship system, illustrating the term's structural centrality.

Two brothers according to the flesh renounced the world and went to live under obedience to a father in the mountain of Nitria. God gave to both of them the gift of tears and compunction.
Hausherr employs the brother-pair as a moralizing comparison unit in Christian ascetic literature, with differential depth of compunction marking differential severity of sin.

His brother-in-law is the second figure in the dream. They had been friendly for a long time, he knew him before his marriage with his sister; they had been in the same business and went to the opera together.
Jung uses the brother-in-law figure in dream analysis as a shadow-adjacent persona carrying projected musical and relational qualities distinct from the dreamer's ego-identity.
