In this text I concentrate on semiotic aspects of the theory of political identity in the work of Ernesto Laclau, and especially on the connection between metaphors, metonymies, catachreses and synecdoches. Those tropes are of ontological status, and therefore they are of key importance in understanding the discursive "production" of identity in political and educational practices. I use the conceptions of both Laclau and Eco to elucidate the operation of this structure, and illustrate it with an example of the emergence of the "Solidarnosc" movement in Poland, expanding its analysis provided by Laclau. I focus on the moment when one of particular demands assumes the representation of totality, which, in Laclau, is left to "circumstantial" determination. This moment inspires several questions and needs to be given special attention if Laclau's theory is to be used in theory of education. It is so because theory of education cannot remain on the level of the ontological (which is the core of Laclau's achievement), but has to theorize "non-ontological" dimensions as well, that is the ontic (i.e. "content" of education), the deontic (duty, obligation, and the normative in general), as well as what I call "the deontological"--the very relation between "what there is" and "what there is not" (including that which should be) as the "locus" of education.
