Understanding Derrida’s “Structure, Sign, and Play”

Deconstruction, a philosophical post-structural theory derived mainly from the work of the French philosopher Jacques Derrida, has evoked a great controversial debate over the past few decades. Promoting a sophisticated philosophical view of literary criticism, deconstruction has always been a complicated topic to comprehend especially for students and novice researchers in the field of literary criticism. This article review paper attempts to present an explanation of the main notions of the theory by reviewing one of Derrida’s most influencing articles on critical theory: “Structure, Sign, and Play in the Discourse of the Human Sciences”. The article which marked the birth of post-structuralism theory, was first delivered in 1966 at John Hopkins International Colloquium on “The Language of Criticism and the Sciences of Man”. This seminal work of Derrida criticizes structuralism for the great importance given to centralism and binary oppositions for the sake of accessing meaning. It can be claimed that the article sums up his ideas on deconstruction which in fact attacks all notions of center, totality and origin. Deconstruction is perceived as a method of breaking down and analyzing text in an attempt to approach some new interpretations which might be totally different from any other previous ones.

Semantic analysis of English proverbs and sayings with lexical components “truth” and “lie”

The subject of this research is the proverbs and sayings with lexical components “truth” and “lie” in the English language.

New Exploration of Logic Starting Point of Audit Theory Structure

As a discipline that has developed for many years, audit has been relatively mature and complete in its theoretical structure. As we all know, the establishment of any discipline requires a set of mature theoretical framework that are logical, progressive from point to surface. This theoretical structural framework is called the theoretical structure, and the research process of the audit discipline also needs to build such a theoretical system to make the audit research planned and structured, then the logical starting point in the audit theory structure will largely influence the direction and development of the audit discipline. In this paper, by expounding the characteristics and conditions of the logical starting point and combining some domestic and international discussions on the logical starting point, the author considers and explores the selection of logical starting point of the audit theory structure, hoping to select an amenable element as the logical starting point of the theoretical system to promote the research and development of the audit discipline.
