Evil and suffering.
Found my college notes on " evil and suffering ".
Evil is generally defined in philosophical terms in two ways.
1. Moral evil.
Moral evil results from human actions which are morally reproachable. The holocaust, which resulted from a combination of cruelty and misguided ideals, is a classic example.
2. Natural evil.
Natural evil results from the malfunctioning of the natural world, which produces entities such as disease and famine. Ex : an earthquake because the result of that natural evil is suffering. The philosophical argument for naming such an event as " natural evil " is because it does not discriminate to whom it strikes with the end result that many innocent victims are often caught in it's path.
I suspect no one would disagree with the definition of moral evil but natural evil leads to a problem for many people.
That problem leads to the following dilema,,,,,,
1. Since God alone created the universe out of nothing, He has total responsibility for everything in it. If he is all powerful, then, He can do anything that is logically possible. This means that He could have created a world free from actual evil and suffering and free from the possibility of ever going wrong. It also means that, should He ever have allowed it to come about, He could end all evil and suffering.
2. Since God is omnisicient, He has complete knowledge of everything in the universe, including evil and suffering. He also knows how to stop it.
3. Since God is omnipotent, He could carry out immediately His desire to step in and stop the suffering but because evil and suffering still exist, that leads to an argument presented by many, is that He can't be omnibenevolent. That no loving God would allow his creation to suffer physical and mental torment for no reason and to no avail.
So that then leads to an argument concluded by reason, that because evil and suffering still exist either God lacks,
1. Omnipotence or omnibenevolence
or
2. He does not exist.
David Hume set out this dilema in " Dialogues concerning natural religion ". Upon examining the qualities of omnipotence, omnibenevolence and evil, he concluded that only two out of the three can exist alongside each other.
Therfore, " either ",,,,
God is not omnipotent " or ",
God is not omnibenevolent " or ",
evil does not exist.
While the existence of evil has been questioned by some, HUme considered that it's effects are felt too widely, and in presence, attested too vividly for it to be dismissed.
Therfore, accepting that evil exists, he concluded that God must either be impotent or malicious. Hume therfore concluded that God does not exist.
This position is supported by the argument that is found in Aquinus " summa theologica ", which suggests that Gods existence in the face of evil is " logically " impossible.
"St Thomas Aquinus, Summa Theologica ",,,,
It seems that God does not exist: because if one of two contraries be infinate, the other would be altogether destroyed. But the name of God means he is infinate goodness. If therefore, God existed, there would be no evil discoverable, but there is evil in this world. Therfore God does not exist "
Since, for Aqunius, the concept of infinate goodness is an essential part of Gods nature, any proof against God's goodness being infinate will constitute proof that God does not exist. The existence of even the tiniest quantity of evil precludes the possibility of infinate goodness.
Aqinas differed from Hume, however, in that whereas Hume, as an atheist, accepted this conclusion, Aqinas went on to reject it.
Aqinas argued that God's goodness is a very different concept from our own, and that his goodness might allow Him to tolerate the existence of what we consider to be evil as a tempory part of His plan.
If this is the case, there can be no logical contradiction in supposing that God is all loving, all powerful " and " has good reason for allowing what " we " call evil to exist.
Something to consider from the above,,,,,
What possible reason might God have for permitting evil to exist in the world ?
and,
Can we consider whether there are any benefits that result from the existence of some evil ?
Maybe we can dijest all of the above today, then tomorrow I can present St Augustines argument. 
Never be overwhelmed by decisions, just consider the right ones and your options will be far fewer.
