Psychology seemed to be condemned to be always searching for an object. This chapter devotes to the presentation of a résumé of Peirce's semiotic logic. The psychological status of the interpretant is dependent of the semiosis to which it belongs. The experience examined in the chapter is an enactive experience, it is the experience that presents the world, it is the experience that results from alive movement that produces the development of an agent and its change into actor. At the same time that the environment becomes intelligible, changes into a meaningful Umwelt where the organism learns what to do, so that its behavior follows a rationale. It is the kind of experience that exist before communication and language comes to the scenery. The chapter dwells on how movement turns in action, and the latter into actuations, so that meaningful objects, situations and the lived Umwelt can appear.
