Critical Theory: An Interdisciplinary Coursebook (in two volumes) is the most comprehensive work written by Dr. Hossein Payandeh in the realm of literary criticism and theory. The present book is a collection of the most widely used critical theories with an interdisciplinary approach. It is written for the post-graduate students (M.A. and PhD students) in humanities. Perhaps the most important feature of the present book is that the author has brought, in a very simple and lucid language, the theory and practice together. Also, for some chapters of the book an example is given from classical and contemporary Persian literature (both poetry and prose) and for some others the examples are taken from contemporary press and finally they are analyzed through the prism of discussed critical theories to make it more accessible. Some critical theories and approaches are missing in the book e.g. Deconstruction approach, Postcolonial theory, and Marxist theory.
