In this seminar, we explore what strange spirits like windigos, Sasquatch, or Star Beings (aliens) mean in Native and non-Native contexts. In Indigenous contexts, such stories carry knowledge about how to live ethically with the world. We will also examine texts by non-Natives that engage with the Native content of these stories, asking whether they engage with this content as knowledge or as entertainment. Our comparative examination raises important questions about the relation of colonialism to the appropriation of Native lands and cultural expressions.
