Saadiah ben Joseph (882-942) was the first major medieval Jewish philosopher. He wrote a commentary on the book of Job, called the Book of Theodicy. In this work he extensively analyzes the problem of suffering and evil. Reprinted with permission from Evil and Suffering in Jewish Philosophy, published by Cambridge University Press.
For Saadiah, there are three purposes resulting from the phenomenon of human suffering—education, punishment and testing. Suffering can help discipline us and point us in the right direction, that is, the direction in which we shall ultimately benefit. Saadiah has both a retributive and a deterrence view of punishment, in that our suffering helps to clear our guilt while at the same time making us motivated to avoid the actions which led to the pain. The third purpose is obviously what the Book of Job is about, namely:
“The third case is that of trial and testing. An upright servant, whose Lord knows that he will bear sufferings loosed upon him and hold steadfast in his uprightness, is subjected to certain sufferings, so that when he steadfastly bears them, his Lord may reward him and bless him. This too is a kind of bounty and beneficence, for it brings the servant to everlasting blessedness (BT, pp. 125‑6).”
As it stands, this is a rather perplexing statement. If the master knows that the servant will bear the sufferings, why subject him to them? Saadiah goes on to strengthen his claim even further by asserting that it is not unjust for a creator to kill his creature in the midst of his normal life span, provided that he is promised recompense. Indeed, he further claims that such sufferings are a sign of divine benevolence, since the future reward is greater than the span of life foregone.
He obviously feels unhappy with the way in which he has made his point here, since he gives a variety of examples to try to show how reasonable his view is. He points out that we may grow accustomed to a particular form of existence, and may dislike being obliged to move onto a different form even if it is to our advantage. This certainly has some merit as an argument when applied to changes within our lives, but when we die we might wonder how we are going to benefit in the future.
