Encounter is the community-founding personal meeting of two persons in self-transcendence. It is not the mere coming-together of two bodies in space, but the reciprocal enactment in which two persons recognize each other as someone, open themselves, and find each other in the “between” that arises through their meeting.
Buber: the Basic Word I-Thou
Martin Buber formulated the decisive sentence in I and Thou (1923): “All actual life is encounter.” (I, §6) Encounter stands in the mode of the basic word I-Thou, not I-It. The Thou is not experienced, not described, not thematized — it is addressed, and in being addressed the I of the speaker comes forth. Encounter is therefore constitutive: it makes the I not the subject of its perception, but the pole of a relation.
In Elements of the Interhuman (1953), Buber unfolds the “between” as an ontological region of its own kind — neither merely subjective nor merely objective, but dialogical. Encounter takes place not in the participants, but between them.
Spaemann: Recognition as Letting-Be-Seen
Robert Spaemann (Persons, 1996, chs. 5 and 8) ties encounter to the thesis on personality: persons “exist only in the plural”. Recognition is not a moral addition to the person, but the enactment in which her personal reality becomes visible for another. Encounter is the form in which persons recognize one another without fitting the other into a schema.
From this follows the ontological rigour: encounter can take place only where two someones stand facing each other. Where there is only something, there can be interaction, but no encounter in the full sense.
Wojtyła: Communio personarum
Karol Wojtyła (Osoba i czyn / The Acting Person, 1969) develops encounter further into the communio personarum: the reciprocal self-giving of two persons who open themselves for the sake of the other. Encounter here is not only cognitive (knowing about each other), but ontologically constitutive (becoming through each other). In the theological-anthropological conclusion of the Theology of the Body (Wednesday catecheses 1979–1984), encounter becomes the primal scene of the image of God in the human being.
Levinas: the Face as Appeal
For Emmanuel Levinas (Totalité et Infini, 1961), encounter is less a meeting than a being-claimed. The face of the Other precedes every thematization; it speaks “You shall not kill” (TI section III B) before any content is formulated. Encounter is therefore asymmetrical: not a meeting among equals, but an address to which one is already exposed before one can answer.
Heidegger: Being-With and Solicitude
In Being and Time (1927, §§25–27), Martin Heidegger determines being-with (Mitsein) as an existential: Dasein is always already being-with with Others, not entering into relation only secondarily. Encounter is the concrete actualization of this ontological constitution. Heidegger distinguishes two modes of solicitude (Fürsorge) — the leaping-in mode (taking the Other’s place, taking his care away from him) and the leaping-ahead mode (letting him become free for his ownmost care). Genuine encounter lives in the second mode.
What Encounter Is Not
The rigour of this determination has a consequence for the AI discussion. An AI pseudo-encounter with an AI system lets the feeling of being heard become real on the human side, but not the being-heard itself — for the second personal pole is missing. Sherry Turkle (Alone Together, 2011; The Empathy Diaries, 2021) and Shannon Vallor (The AI Mirror, 2024) document empirically what follows structurally: pseudo-encounter can displace real encounter without being able to replace it.
Ontologically, the difference is not gradual but categorical: encounter requires two persons. A simulating apparatus — even a linguistically convincing one — remains a something, not a someone (Spaemann). The human being’s perception can deceive; the ontological structure cannot.
Encounter as Constitution of the Personal
The tradition (Buber, Ebner, Rosenstock-Huessy, Spaemann, Wojtyła) agrees on one point: personality does not merely become visible in encounter — it is co-actualized in the enactment of encounter. I become what I am at the Thou that addresses me and that I address. The self-transcendence of the person is her ordination toward the other; encounter is its realization.
From this follows at the same time the ethics: whoever denies the other the encounter — through reification, functionalization, instrumentalization — fails not only the other but also himself, because he deprives him of the pole-position at which his own personality could be enacted.
Ontological Classification
- is a subform of: Interpersonal relation
- constitutive components: Address, Face, Self-transcendence
- realizes: Communio Personarum
- frequently takes place in: Dialogue
- disjoint with: AI Pseudo-Encounter
- exclusive to persons: a Thou-pole cannot, conceptually, be occupied by a something
