On a Class of Concepts

English translation and postprint of a paper originally published in French under the title 'Une classe de concepts' in Semiotica (2002), vol. 139, pp.121-3. In this article, I aim to develop the construction of a general class of concepts, which notably integrates a number of commonly used polarized opposites. The starting point of this construction does not lie in conventional, lexicalized concepts—that is, concepts for which there exists a corresponding word in the everyday language of a given language. On the contrary, the approach guiding the construction of this class of concepts involves an abstract definition of the latter, without consideration of whether the corresponding concepts are lexicalized or not. Once such a construction is achieved, it becomes possible to verify that the concepts thus constructed do indeed correspond to lexicalized concepts, while others cannot be matched with any word in everyday language. Ultimately, this construction allows for the proposal of a taxonomy of concepts that serves as an alternative to the one based on the semiotic square defined by Greimas.
