Friendship as a Mirror: Who Am I with You?

Friendship as Self-Knowledge

In sociological analysis, friendships emerge as central spaces in which modern subjects reflect on, negotiate, and constitute their identity. This connection can be traced through several theoretical strands.

Günter Burkart (2006) describes a “culture of self-thematization” that emerged through individualization and psychologization since the 1960s and 1970s. In this culture, individuals are increasingly called upon to turn reflexively toward themselves — what defines them, what sets them apart, how they interpret their lives. Not only professional settings like therapy or counseling are available for this, but also everyday relational encounters. Holger Herma (2019) calls such contexts “reference spaces of the self” — places and relationships where people have the opportunity to talk about themselves and reflexively attend to their own lives. Friendships are one such reference space. Herma understands the self as the “result of (self-)reflexive attention to one’s own ego” — it becomes possible to distinguish oneself from others and to experience oneself as a center of agency.

The Friend as Another Self

Eva Illouz (2020) analyzes the triumph of a “therapeutic discourse” that, as a cultural matrix, provides metaphors and narrative templates through which we explain ourselves. Applied to friendships, this therapeutic model functions like a script: it offers orientation for reflecting on relationship status, processing friendship events, and negotiating needs for closeness or distance.

Niklas Luhmann (1982) adds a systems-theoretical perspective: in a highly differentiated society, there is a compensatory need for personal communication in which one can assert one’s individual uniqueness and be seen as a “whole person.” Friendships promise — similar to love — authentic self-experience and a “validation of self-presentation.” The non-institutionalized nature of friendship makes it especially suited for this: it is diffusely structured, not functionally specific, and allows an openness that enables stable resonance. Friendship does not merely create a space for self-thematization — conversely, self-thematization also forms the basis for constituting friendship by enabling a specific kind of intimacy (Cocking & Kennett, 1998).

Stabilization Through Friendship

This perspective connects individualization theory (Beck, 1986), the sociology of the subject (Reckwitz, 2021), and resonance theory (Rosa, 2021). Its strength lies in weaving different sociological strands into a coherent picture: friendship is not merely a form of relationship but a condition for the possibility of modern subjectivation. The reference point for biographical self-reflection is one’s own life and the significant others in close relationships — the realm of friendship thus offers opportunities to attend reflexively to one’s own life through encounter with others.

The argument is primarily theoretical and difficult to test empirically. The claim that friendships are particularly suited spaces for self-thematization competes with the observation that other contexts — online blogs, therapy, diaries, social media — also serve this function (Herma, 2019). The thesis also presupposes a particular kind of friendship involving dialogic communication and emotional depth. Whether all empirically observable friendships display this quality is doubtful — the very trivialization of friendship could undermine its self-thematization function. Unlike romantic partnerships, however, the friendship pattern is more elastic, since friends are not expected to be of supreme personal relevance.

Resonance Experience

In sociological analysis, friendships fulfill a central stabilizing function for individuals who have been released from traditional structures by societal modernization processes. This thesis forms a cornerstone of the sociology of friendship.

Friedrich Tenbruck (1964) argues that individuality rests on liberation from traditional social structures: “The discovery of the self in the sense of individuality presupposes a differentiation of the social structure.” Since this liberation also brings uncertainty and loneliness, friendships serve a compensatory function. They make it possible to build and solidify individuality: “In concentrating on each other, both friends find themselves committed to a self in a twofold way.” For Tenbruck, friendships are “the complement to an incomplete social structure” — they fill the gap left by the dissolution of traditional community forms.

Non-Institutionalization as Strength

Siegfried Kracauer (1971) radicalizes this idea: true friendship can save the individual from the impositions of modern life, becoming a “place of refuge.” While modern society forces us to “splinter ourselves into a thousand life circles,” friendship allows us to encounter another person as a collected, whole human being. In the echo of friendship, self-assurance is strengthened.

Hartmut Rosa’s resonance theory (2021) supports this perspective: friendships enable resonance experience — a positive relationship in which subjects are convinced of “being connected with something that is genuinely responsive.” Friends matter “because they answer us and can touch us and because we can reach them.” Heinz Bude (2008) updates this line of thought by declaring friendships the “vanishing point of social hopes”: where marriages and family bonds grow fragile, friendship appears to be a particularly fitting form of personal relationship — friendships not infrequently outlast partnerships and neighborly ties (Bude, 2017).
