The main question of our paper is: how Ibn-sina and Mulla-Sadra demonstrate the completeness of the existent world, despite the evils which we see clearly in that? Our answer is that these two philosophers take an apriori approach on this problem and say: Since this world has been created and is governed by God, who is All Complete, and nothing can prevent him from what the wants to do, so the world must be complete. On the natural and ethical evils we see in the world, they say: (1) these are very little in respect to good things;(2) we can show by argumentation and analysis that these are non-existants (that is, privation); and(3) these evils are the unblessed offshoots of the change , the evolution and the contrariety of the natural world, which are it’s essential part; and their elimination is equal to eliminate the very natural world, which , in its turn , is equal to eliminate the much good. The result of their argument is that our world is best possible world and it is impossible to have another world in place of it.
