Definitive Cognition of the Ultimate Principle of Being; Mir Damad's Point of View

The possibility of definitive cognition of God، as the ultimate principle of Being، is an important question of metaphysics. Mir Damad believed that God is obvious in terms of existence in itself، but as relative existence، definitive cognition of God can be gained through complex argument of fact. Criterion of certainty is present in the formation of this kind of argument of fact. Presentation this argument is one of the Mir Damad’s logical innovations، and in addition to definitive cognition of God، is useful in explaining that which kind of argument is used in first philosophy.
