Abstract
Mulla Sadra mentions two definitions about evil, one of them is that something lacking of essence or lacking of its a perfection and the other one is that all possible living creatures may have deficiencies.
In order not to fall into the paradox of some existence are evils, he describes evils in terms of two ways that are by itself evil and relative evil. By itself evil is absolute non-existence so that it doesn’t need perpetrator.
Mulla Sadra describes the evil as four categories that metaphysical, natural, moral and perceptual. He utilizes Aristotle's finest universe theory to solve the problem of relation between evilness and spiritual creation.
Mulla Sadra he explains five universes with the example of absolute goodness, much goodness then less evil, goodness and evil are equal, less goodness much evil, and certain evil. He proves the most beautiful universe as much goodness then les evilness. Then he solves the problem of evil in terms of recognition divine decree and destiny.
