Abstract

Mullā Sadrā appeared in the philosophical field when the prevalent philosophical questions were principality of existence and principality of quiddity. Although he first held the theory of principality of quiddity, later in a cognitional rotation he accepted the theory of principality of existence. Such a rotation gradually causes a wide revolution in the realm of philosophy, and consequently it yields principles such as unity of existence, analogicity of existence, and intensification of existence. He propounds external objectivity of existence, knowledge, beauty and other qualities of perfection as his philosophical principles. Thus, due to Mullā Sadrā’s basic principles, we can attain to principles such as principality of beauty, unity of beauty, analogicity of beauty, and intensification of beauty.
