Abstract The issue of the ordering of the ten trichotomies is one among the many questions still open regarding Peirce’s extended theory of signs. A proper decision regarding the order of the ten trichotomies demands a discussion of the entire semiotic process. The aim of this paper is to discuss the order of the trichotomies related to the mode of being of the immediate and dynamical objects. Therefore, it addresses only one part of this process, which concerns the relationship between the sign and its objects. When subdividing the object, Peirce begins to consider the immediate and the dynamic objects as trichotomies, that is, aspects to be considered in the definition of the classes of signs. The introduction of these two trichotomies brings in a problem: how to order them in the system of ten trichotomies. Diverging opinions regarding this ordering are found in Peirce’s texts, and in his commentators. We will investigate this problem by seeking a sort of pragmatic clarification of the matter, presenting a reflection about the philosophical and semiotic consequences of the different proposals for the ordering of these trichotomies. Placing the dynamic object after the sign may even help to explain the functioning of fictional signs, but is this coherent with Peirce’s philosophy? On the other hand, would it be possible to talk about lying signs if every object was determined by its own sign?
