This article seeks to consider the meaning of diversities, from the reading of Carlos Skliar and the first Martin Heidegger, as a search to meet, coexist, and coexist in educational spaces. Based on Carlos Skliar's proposal, school and teacher training are understood from a pedagogy of absence and hospitality. Both would generate a correlation in the forms of appropriation of being a teacher from absence and hospitality that can be projected to the processes of initial teacher training. To establish absence means understanding the other as an incomplete being, who they must be for tomorrow and who they are not yet. Instead, hospitality is an invitation coming from respect and tolerance, but to be understood as abnormal and needing improvement. We invite the reader to search for a pedagogy of openness, understanding, and joint action. Also, to approach diversities as a co-inhabitation, considering they are established in our syntaxes as ways of understanding the world and listening ethically to others. We use the term "diversities" to broaden the concept and not as a univocal way of thinking.
