Today, most of academical persons suggest frequently one standard opinion about ecological discourse. So to speak, they generally have agreed that the ecological discourse we scholars need is not yet arrived, or constructed otherwise. If that is the case, we need attempt to construct some possible models on that. For discussing the ecological discourse as ‘not yet’, Jacques Lacan’s four discourses─master’s discourse, university’s discourse, hysteric’s discourse, analyst’s discourse in turn─suggest that we need analyse our hypothetical ecological discourse at the very first time. The four discourses consider some major factors like language and (its) social links, subject and (its) other. Moreover it subverts the existing modern trend of thoughts against itself. A ecological discourse as refusing the anthropocentric notions, in that sense, has some analogy to the four discourses. In this paper, we attempted, within the limits of the possible, to make a model of (ecological) four discourses from Lacan’s original one. As a result, (ecological) four discourses outputs one (possible) way of analysing eco-centric literatures, and suggests how to reestablish ‘greenly’ the ecological (un)consciousness/discourse being interconnected to the other various discourses.
