The focus of the present paper is that ‘cognitive literary studies’ are beneficial for ‘literary studies’. There are scholars, like Adlerand who are not in favour of exploiting the science based concepts for literary interpretations. Their argument is that the ‘two approaches may simply be incommensurably different’. Still, there are the scholars, like Jackson and Levingston who assert that cognitive literary studies, based on scientific concepts are able to provide new, enticing and legitimate extrapolations to the literary interpretations. However this never means that the existing critical theories of literary explanations have no value. They certainly have their procedures and concepts to achieve their aims. If combined with the principles of cognitive studies, wonderful interpretations would appear. Then we would taste ‘new knowledge’.
