The present work aims to examine the treatment of the concept of anxiety in Being and Time (1927) and in the lecture What is Metaphysics? (1929). In Being and Time, Heidegger deals with the feeling of anxiety, emphasizing the relationship of this concept with the possibilities of impropriety and property. In fact, in §40 of the major treatise, the philosopher presents anxiety as the finding of oneself that singularizes being-there. In turn, in the 1929 lecture, the philosopher presents this concept emphasizing the role of this concept in the discovery of being. In the metaphysical question about nothingness, the philosopher uses the finding of anxiety to discover the transcendence of being-there. At stake is the relationship between being and nothing revealed by the encounter of anguish, in the lecture What is Metaphysics? For Richardson, this difference foreshadows the so-called turn in Heidegger's thought. According to Sheehan, however, it is possible to think of at least three meanings of Kehre in Heidegger's thought. It is up to us to define which direction of turn we are referring to when we deal with the difference in the concept of anxiety in the two works mentioned. Our objective, therefore, is to investigate whether the 1929 lecture can be read as a foreshadowing of the change in orientation of Heidegger's thought in the 1930s. It is a reorientation of Heidegger's philosophical project, which moves from a perspective transcendental to another, this time focused on the history of being.
