The present paper contains an attempt to restate some aspects of the problem of universals (abridged here as "PU") in the frame of recent logical semiotical techniques, and in face of some new ontological doctrines. A solution of the PU will not be attempted here. The method is purelyspeculative, and no references will be made to history, except to some quite recent ideas.¹ The language used will be informal, as it is necessary in a study of this kind, preceding the stage of formalization.
