By your line of reasoning then homosexuality isn’t wrong either.
Rather, that Natural Law is an inadequate system for determining the morality of things.
Why would you need to prove that masturbation is in and of itself harmful in order to be wrong?
Why else would it be wrong? The conservative Christian would say “it deviates from what God originally designed.” Okay, but there are *plenty *of things in the world that deviate from what God originally designed for human beings that are perfectly acceptable. See the next point for a more complete look at the issue:
On what do you base your observation that our necks “are clearly not designed to wear jewelry”?
A penis is designed to
… well, we all know what it’s designed to do. A neck is designed to hold up the head and serve as a passageway between the organs of the head and the organs of the body. But a neck* can* be used to hold jewlery, with no harm done to the neck or the person as a whole. Similiarly, the penis *can *be used to derive personal pleasure to one’s self, with no harm done to the penis or the person as a whole (as this study has shown).
It’s
not an analogy. It’s an application of Natural Law theory to the idea of masturbation and the idea of wearing jewlry. Natural Law is concerned with the fact that both deviate from the original design of those things. But, for reasons I will describe below, it doesn’t have a problem with wearing jewlry but does have a problem with masturbation.
Religion (in Christianity, mostly thanks to Augustine) has taught that masturbation was wrong. Natural Law is just a way to justify that belief. But it just doesn’t work. It’s okay to believe that masturbation is wrong on faith, but don’t pretend that Natural Law is a sufficient way to come to the conclusion that masturbation (or driving a car, or homosexuality, or wearing a necklace) is wrong using reason alone. As I have illustrated above, it doesn’t work.
Your hands can clearly “fit” around your neck also but don’t you think it would be wrong to choke yourself?
Correct. I don’t subscribe to the notion of Natural Law. I’m pointing out
why. What’s the difference bewteen weaing a necklace and choking yourself?
Harm.
Wearing a necklace is NOT harmful. Masturbation is NOT harmful. Choking yourself, however, IS VERY harmful.
Misusing the sexual powers has lasting moral effects regardless of any known physical effects.
“Moral effects” meaning you think God thinks it’s wrong. Why do people think that God thinks it’s wrong? Because they think it deviates from the “original plan” for human beings. But these people fail to realize, I have said above, that there are MANY things that deviate from the “original plan” for human beings that are NOT wrong. See what I have written above for a more thorough look at it.
