Abstract: The study of language in the 20th century experienced three stages—formal linguistics， behavioral linguistics and event linguistics， which respectively regard language as language signs， speech acts and discourse events. By taking language as an event， discourse linguistics highlights the uniqueness， heterogeneity and contingency of discourse events. The deconstruction practice of Michel Foucault， Barbara Herrnstein Smith， Hayden White and others relies on the exploration of heterogeneous factors behind discourse events， highlighting the potential of discourse analysis as a deconstruction strategy and path. Discourse analysis， as a method and path of deconstructive criticism， analyzes things in a complex interactive system with multiple factors and opposes dichotomy and monism. Its specific deconstruction path is the empirical path. It forms the deconstruction by exploring boundary cases that cannot be covered and commensurable by an overall framework.
