Rowe and Swinburne

…

…evil in the world takes away one more actual good, and in reducing the severity of evil in the world you must conversely be removing the level of goodness that can be achieved. It must be obvious then, that it is better for one to live a life and endure considerable pain for the possibility of greater goodness, than it would be to live a fleeting inefficacious life, where you existence is trivial at best.
