The purpose of this paper is to present and compare three phenomenological theories of questions that arose in first decades of the twentieth century. These are thoughts of J. Daubert, M. Heidegger, and R. Ingarden. Such a comprehensive subject of research not only allows us to examine the most fervent period of phenomenology when the common assumptions and chief points of the phenomenological movement were formed, not only gives us occasion to compare the phenomenology of the various representatives whose ideas have not yet been compared, but also provides an opportunity to look at the origins of twentieth-century erotetics, which, especially in Poland, has had a number of prominent representatives.
