Although letting go or letting pass into oblivion has always been seen as a standard way of organising cognitive processes on an individual and a collective level, nowadays, forgetting manifests extraordinary speed and profundity. Ideas, their authors, and technologies are subject to swift oblivion, or they are becoming trans- or disfigured over quickly.Despite the usual technologies of oblivion - the continuous redefinitions of the old/new divisions constituting the next one modern, the subsequent destruction of the old as culturally inappropriate, oblivion is also fueled by disciplinary biases about what should and should not be included in a disciplinary biography memory. One of the variants of reflection of signs "suppressed" by official semiotics and recognized as non-semiotic is phenomenology, the branches of further development of which are known either narrowly in local scientific collectives or completely unnoticed. However, it has semiotic applications in all branches of this philosophy.The paper is devoted to marking the line of phenomenological semiotics starting from Brentano's sign-like treatment of intentionality, "Zur Logik der Zeichen"/On the Logic of Signs (semiotic)/ written by Edmund Husserl in 1890 and the further development of it. The most forgotten seem to be the predecessor of linguistic structuralism, Anton Marty, and the father of narrative phenomenology, Wilhelm Schapp, who captures the stories' state of oblivion. The latter forces us to revise the possibilities of theories of signs, thematising Schapp's "to that-meant"/hizugemeintes/ and the "to that added-thought"/hinzugedachtes/ and other applications of semiotics in phenomenology.
