 Khirad (wisdom) is the type of wisdom that brings about a rapprochement between the poetic and discursive modes of thought, one that sees the fundamental irony in what appears to be a senseless human existence within an orderly and complex physical universe. For Khayyam the mathematician-astronomer, the universe cannot be the result of a random chance; on the other hand, Khayyam the poet fails to find any purpose for human existence in this orderly universe.
