In this paper I deal with Schutz's approach to intersubjectivity. First I present his concept of the mutual tuning-in relationship as a polythetic constitutional process. Then I retrieve some of Zaner's criticisms about Schutz's characterization of the thou-orientation as an appresentational and symbolic relation. Then I go back to Scheler's perceptual theory of the alter ego sketching out a number of differences with Schutz's theory, contesting some of the criticisms posed by Zaner. After this I take Luckmann's description of the process of mirroring as a key concept to understand how the tuning-in relationship is established. Finally, I go back to try and answer Zaner's criticisms.
