Liu Yang points out in The Journal of Humanities (9th issue, 2021) that Saussure's language theory based on the principle of difference helps to clarify the general creative process of art, but does not help to explain the implicature of art. Formalist literary theory and structuralist narratology under its influence both explain the implicature by inferring from locutionary intention and from the logic of jouissance, ignoring the essence of the latter as the stimulus of pain, and bringing about the sociological consequences that break the self-clarity but neglect the sublime. This ideographic limit is therefore under the impact and reflection of contemporary event ideas in two related directions, that is, to explain the implicature of art from the new perspective of events and move towards event-based literary theory by restoring the life form of Saussure's theory of language and making use of heterogeneity to activate another homogeneous causal entity in which Saussure's theory of language is involved.
