Based on the etymology of truth that Heidegger 1986) does in Sein und Zeit (Being and Time), and taking into account some everyday characterizations that Berger and Luckmann do (1998), I hypothesize that art is an ontological fissure in everyday life. If truth, as Heidegger states, literally means in classical Greek "unconcealment" (the initial alpha of the word is privative: what would be the " unconcealment" that art does, since art as well is posed as true in Heidegger? Furthermore, I explore the poetic, which not only refers to the poetic in literature, but also to the most general meaning of poiesis which means "creation." Finally, the question inevitably arises as to whether art without beauty or sublimity is possible, or whether beauty is inherent to art. In this part of the article, I review, in very general lines, some theses by Arthur Danto.
