This study intends to highlight the existing relationship between semiotic theory and social thought. This is not based on the ideas of identification and congruence that denies the sanctity of specialization 2 that distinguishes knowledge and sciences, but rather on the basis of mutual interaction and responsible negotiation between these knowledges and sciences. If we accept, for the sake of argument, that the two knowledges rise to the status of knowledge; We will review this relationship on an epistemological basis that stems from a critical vision of the theoretical foundations upon which the scientific discourse of both knowledges is based, in that they are scientific projects. Because both Durkheim and de Saussure Grimas sought to elevate their theory to the status of science, but we will focus it here on the explicit and latent social backgrounds in the semiotic theory and the elucidation of its citizens.
