On the evening of October 15, 2026, a small lounge inside Oregon State University's International Living Learning Center will fill with a story that has traveled a very long way. Kafej Campbell, a member of the Kaingang people of southeastern Brazil, will stand up in the building at 1701 Southwest Western Boulevard in Corvallis and tell the room about their tribe, their own winding path back into it, and a cosmology that divides the entire world into two complementary halves. The event, billed as "Queer & Indigenous: Queer Kaingang Indian," is free and open to the public.
The Kaingang are one of the largest Indigenous peoples in Brazil, numbering roughly 51,000 people, according to the Instituto Socioambiental's authoritative encyclopedia of Indigenous peoples in Brazil. They speak a language belonging to the Jê family and live across more than thirty Indigenous Lands spread over four states -- Paraná, Rio Grande do Sul, Santa Catarina, and São Paulo -- a fraction of the territory they once held. Their contact with non-Indigenous society began at the end of the eighteenth century and hardened in the mid-nineteenth, when traditional political chiefs accepted alliances with the white conquerors and took on the role of capitães, a position that proved pivotal in the pacification of isolated groups subdued between 1840 and 1930. The consequences -- land expropriation, internal factionalism, and ongoing conflict -- have shaped Kaingang life for generations. Yet, as the encyclopedia notes, their social structure and cosmological principles remain in force, continually renewed by the circumstances each community faces.
It is that cosmology that gives Campbell's talk its unusual shape. The Kaingang are sometimes described as the Tribe of Harmonious Dualisms, organized around two opposite and complementary categories: Kamé, associated with the Sun, and Kairu, associated with the Moon. This is not a casual metaphor. Researchers studying Kaingang thought have found that the Kamé-Kairu binary functions as a totalizing classificatory system, one that encodes kinship, exchange, and alliance, and extends outward to order the natural world. A study published in the journal Ciência & Educação, drawing on a mathematics and science training program for Kaingang teachers, went so far as to propose an analogy between this dual system and binary logic itself -- the same on/off, yes/no structure that underlies computer circuits. The Kaingang, in other words, have been running a binary system through their social organization for a very long time.
At the event, attendees will not simply hear about this structure; they will be sorted by it. Campbell plans to guide the room through an activity in which each person discovers whether they belong to the Sun people or the Moon people. It is the kind of participatory moment that turns an abstract anthropological fact into something a visitor can carry home about themselves.
The speaker's own biography is as much a part of the story as the tribe's. Campbell is a University of Vermont alumnus and a former UVM staff member, and currently serves as director of diversity, equity, and inclusion at the Howard Center, the Burlington, Vermont-based provider of mental health, developmental disability, and substance use services for Chittenden County. The UVM listing for the event describes them as "a beloved member of our local community" -- a phrase that captures the particular role Campbell plays in a small state, where an Indigenous Brazilian voice has become part of the civic fabric.
That the event is framed as both queer and Indigenous is deliberate. The pairing places Campbell's identity and their tribe's story in conversation with a broader movement to recognize Two-Spirit and queer Indigenous people, whose experiences are often flattened or erased in mainstream discussions of both queerness and Indigeneity. The Kaingang's dualistic framework, with its insistence that two opposite forces are not enemies but partners in making a world, offers a natural bridge into that conversation. The event is timed to follow Indigenous Peoples' Day on October 12, extending the observance into a more intimate, story-driven setting.
The venue itself is fitting. The International Living Learning Center is Oregon State's newest residence hall and the first on the Corvallis campus designed specifically to accommodate international students, a building whose whole purpose is to put people from different places into daily proximity. Its ground-floor lounges host a regular International Communi-tea Hour, and its calendar is full of cross-cultural programming. A talk about a Brazilian Indigenous people, delivered by a speaker who now lives and works in New England, in a building built for international exchange in western Oregon, is exactly the kind of layered geography the space was made for.
For anyone in the Corvallis area, the practical details are simple: the event is free, and it requires no registration or prior knowledge. What it offers is rarer than the price suggests -- a chance to hear a Kaingang person tell their own story in their own words, and to walk out knowing something about yourself that you did not know when you walked in. Whether you turn out to be Sun or Moon, the answer comes with a lesson in how a people halfway around the world have long understood that two halves make a whole.
