Viewing the Dual Linguistic Contrast and its Application in the Persian Traditional and Contemporary poetry

Dualities exist generally in natural phenomena and human thought, and human life cannot be understood and explained in terms of thought of contrasts and dualities. Undoubtedly, in life in many respects, there are contrasts and dualities, and each duality is one of them. The two sides are opposite without disagreeing with each other, and in each duality, it proves the vitality of life, which is eternal and equal. Then, duality is the basis of construction studies of meaning that duality took appearances as its beginnings, so that it has become a feature of human thought.
