Both of you attempted to address my argument that although coldness may be the absence of heat, we nonetheless feel the effect of coldness, which does not take place due to absence. Either way, if this analogy applied, then in your view, evil does not really exist. This has major implications for your theology. Such as your doctrine of original sin, for example, you must assert that inheriting guilt is inheriting the absence of something, or explaining how one became guilty in the first place.
Neither of you attempted to address my argument of drinking poison, which I stated was a better example. Moreover, you do not take into consideration the existence of certain diseases and illnesses that are not simply caused by absence of good health, but that one who is healthy may easily be effected just as much as an unhealthy person. Finally, you do not consider as to whether the human intellect can define good and evil, or whether only the creator of good and evil define can good and evil.
First of all, Latin Catholic theology does not hold onto original guilt, this is rather the Reformed position adopted from St. Augustine; and as great as a theologian he was, he wasn’t always correct. Besides, you’re gonna have to ask Calvinist to define “guilt.”
We assert only the consequences, not the guilt, is inherited from Adam. Original sin the absence of sanctifying grace in a person, the Catholic encyclopedia says:
“…
Original sin is the privation of sanctifying grace in consequence of the sin of Adam. This solution, which is that of St. Thomas, goes back to St. Anselm and even to the traditions of the early Church, as we see by the declaration of the Second Council of Orange (A.D. 529): one man has transmitted to the whole human race not only the death of the body, which is the punishment of sin, but even sin itself, which is the death of the soul [Denz., n. 175 (145)]. As death is the privation of the principle of life, the death of the soul is the privation of sanctifying grace which according to all theologians is the principle of supernatural life. Therefore, if original sin is “the death of the soul”, it is the privation of sanctifying grace.”
Now, second, in regards to your example of poison, there is nothing objectionable about it, I might agree with you it is a better example, but not in the way you may think.
Now, third, as to your objections:
Lack of good health is just that, the lack of good health. When somebody has a disease of any kind, nobody says they’re in good health. Good health is lacking when there simply is no health, not matter how the person becomes unhealthy. Does a perfectly healthy person who caught the AIDS virus still have health? Has the heroin addict who is severely malnourished never had health (unless they were born unhealthy)? Health is in the state of being healthy, a person with cancer surely is not a healthy person and thus lacks health. Again, you are misunderstanding privation.
As for goodness, it [goodness] is a fundamental attribute of God, and without it God would not be God. It is not something that can be relatively defined, not even by God. Because goodness is a fundamental attribute of God, there can be no evil of God, and so this evil is not something of God but something absent of God.
Edit: The root of your objections seem to be calling for an “absolute” privation, in the sense that whatever object you have in mind was never there in the first place.
