In absence of literary criticism and it's language (A study on absence of literary criticism reason in premodern literary discource)

Literary criticism and it's necessery language doesnt have enough precedence in Persian literary history, becouase the popular language in premodern discourse was the "praise/ dispraise language". The writers and poets in this era usually used praise language and sometimes used dispraise language. But when parliamentary stablished in modern discourse, this language replaced by criticism language gradually and criticism language changed to usual language in modern discourse. The reason of this change must be researched in change of discourse and it's presupposithon. The praise/ dispraise language can be a usual language in a unequality structure, but criticism language is the result of a modern discourse that it's presupposithon is equality and just in this discourse the literary criticism and it's language can be and raise.
