This article is structured around two main purposes. The first consists of an analytical tracing of the theoretical place of the imaginary in Les vérités de La Palice. The imaginary dimension can be articulated around three axes: first, it operates as the space of the "as if" that masks the epistemological discontinuity between the real object and the object of knowledge. Second, it acts at the point where meaning seems inherent in words, covering the materiality of meaning and producing an illusion of transparency, necessary for discursive functioning. Third, the imaginary dimension emerges as an instance of identification, where the subject is constituted in and by the subject-form of ideological interpellation, that is, the imaginary "me-moi" as "subject of discourse." The second objective of this article is to explore the potential of Pecheux's contributions on the imaginary for various analyses of the relationships between space, subject and meaning, and to propose ways in which the study of space can contribute to the development of this materialist perspective. To this end, we offer a reinterpretation of research conducted by the authors of this article on the social production of border spaces and processes of landscape formation.
