Peirces Concept of a Sign and the Lacanian Signifier
According to Peirce the essence of the sign lies in its triadic interrelated structure, namely: a representamen, an object and an interpretant, in which the object is brought in relation to an interpretant by the representamen, such that the interpretant is, in turn, a sign of the same object. Lacans conceptualisation of the signifier shows a surprising resemblance with the ideas of Peirce about the sign. Thus their definitions reflect a same structure: the signifier as well as the sign have to be situated in a chain, for both an ultimate meaning is impossible and a meaning is always determined afterwards.
