Abstract
This paper studies the different transformations of interdisciplinary study undergone nowadays in the domain of comparative literature. It examines primarily the discourse of "inter" or "crossing" and see how it is established and verified. It begins with a survey of the criteria of drawing a boundary for a discipline from the classic period through the postmodern era. The paper continues to present four modes of boundary-crossing adopted most frequently by postmodern scholars, namely, a priori, imaginary, institutional, and symbolic. To exemplify the latter, the paper also demonstrates a comparative study between Jacques Lacan's concept of aggressivity and Hieronymus Bosch's "Garden of Delights"
