Hey,
Yeah basically the whole, ‘evil as necessary for realisation of good’ idea I disagree with. I’ll try outline why below.
Firstly, it suggests that no good can be achieved without first the existence of some evil. Now that evil may not necessarily have to be experienced by me, but it must exist somewhere. This seems clearly wrong. I can experience many goods without having evil. Love, happiness, joy can all be experienced by me without some prior evil. And there is no evidence to suggest that my experience of love, is a result of some counter evil elsewhere. I took great joy in seeing my 2 year old daughter open and play with her birthday presents last week. What possible evil occurred that allowed that joy to be possible?
Secondly, it is true that some goods can only be accessed through the existence of evil, courage, sympathy, generosity , etc… However I think there is a lot of explaining to be done to show why these goods are better than the ones we can have without evil. For if they are no better than love, joy or happiness, then what is their purpose? I would suggest they are not better goods, and hence their existence along with the existence of evil that accompanies them is not justified in this sense.
Thirdly, as Mackie suggests in his writings, the ordering of goods, leads us to an infinite regress. If second order goods are better than first order goods, then logically there will be second order evils, with third order goods to defeat them, and so on.
Fourthly, by thinking in this way, it seems to suggest that because evil makes necessary good, we should promote evil. The more famine and disease there is to overcome the more good will be achieved. That seems to be a completely backward notion, but yet seems logical under this theory.
Fifthly, by saying God could not create good without evil, limits his power. I can imagine a being who could create good without evil, and this being is surely greater than God.
Lastly, if we must have evil to know what good is, as Fent proposes, I would reply by saying why do we need to know what good is? Why must we contrast it with evil? If we lived in on a planet where only one degree of heat was possible, we wouldn’t have terms like hot, cold, mild, and freezing because there would be no need. In fact the whole scale of temperature would be redundant. So similar is the notion of good and evil. The fact there is a comparative scale is obvious by this discussion, but if only one level of good/evil existed then we would again have no notion for any of these terms. My question is why is this not possible? I believe for God, it should be.
