John –thanks for reply.
Under Natural Law, human actions are right that promote the values specified by the natural inclinations of human beings and wrong as they do otherwise.
Procreation is one such value. It is a natural human inclination. Homosexuality shuts the door on this value. Deliberately, unquivocally.
But 1] We are discussing the justification of Natural Law morality.
Laurie, you are shifting the goal posts! The topic was supposed to be
Can Homosexuality Be Proved Wrong From Natural Law. Now you are saying we are discussing the justification of Natural Law morality. Actually, I thought that might have been the problem for you, because no matter how some of us here advanced Natural Law arguments to prove that homosexuality was wrong, you kept asking ‘but why is it wrong’. You were rejecting the very proofs the question was demanding. And, in the process, you were effectively rejecting Natural Law itself. Unfortunately, the thread question,
Can Homosexuality Be Proved Wrong From Natural Law, suggests an a priori acceptance of Natural Law arguments so the debate can proceed and the question be answered. A little later I shall return to the ‘justification of Natural Law morality’, but that is a big topic of its own Laurie. I suggest in the meantime you take note of
Earnest Bunbury’s post, above. It gives a good starting point for this aspect of this discussion.
2] Celibate people also ‘shut the door to this value’. [you will now reply with a ‘Yes but…’ which will not persuade any but the committed.]
Again, Laurie, the topic was about homosexuality, that is, active sexual practices. Now you swing the goal posts further apart again and introduce Celibacy into the argument. That begs the question Is not practicing homosexual sex wrong according to Natural Law. Or even is no sexual practicing wrong according to Natural Law. It starts to get a bit ludicrous in the context of this debate and is, in fact, another topic for discussion.
3] Gay people can procreate in various ways – but you will again reply ‘Yes but…’
Now how do you now how I will reply?

I will say, however, gay people can’t procreate by having gay sex! I actually touched on this topic in my previous post.
To answer the rest of your post. The problem arises for me because my daughter and partner have been in a stable faithful relationship for 20 + years and, by all ordinary standards are very happy and fulfilled by it. There are many other couples who are the same. So it is just not persuasive for you to assert that their lives are not flourishing, thriving, [chose your own words]. No doubt leading a straight life works for most people however for many gays it would mean a life which was arid and loveless. So to say that Natural Law Ethics is justified because it leads to everyone leading thriving lives is not correct for them – hence the problem.
I understand and am sensitive to your problem Laurie. I do not know your daughter and cannot make judgements about her. I have tried to avoid mentioning her and so have stuck to general principles, such as defining
flourishing. Particularly in terms of that goat farm of yours!

On that point, a beautiful point was made by
momor when he/she wrote * It’s hard to see the necessary order of things required for the entire farm operation when you are looking into the eyes of only one sweet goat.*
It is beside the point to claim that many gays are promiscuous or whatever – we are talking about those who are in stable and happy relationships and who cannot be tarred with this brush.
The question was about homosexuality, Laurie, not a certain class of practicing homosexuals. You have again shifted the goal posts and now want us to focus on just one type of practicing homosexual.
So back to my question – if something is unnatural or disordered [as defined by Natural Law ethics and the Catholic Church], why is it also wrong?
Because Natural Law reasoning tells us so, Laurie! That’s the simple answer.
Now go to
Earnest Bunbury’s post. He says
Belief in a supreme law giver is paramount if one is to make law a standard that is not to be usurped for a whim or desire. That means we must accept Aquinas’s view on Natural Law and the manner in which the Church adopts the Natural Law. However, in discussing Natural Law, we can also move God out of the debate and insert the Big Bang, or Mother Nature, or whatever else takes your fancy. I wrote about this in an earlier post, but you bypassed it. The point is, as Earnest Bunbury tells us, is that the Natural Law is based on an
objective standard. That is the crucial point to remember. Positivism removes that objectivism and we are left with relativity and Law as defined by man according to his whims and desires. Mother Nature, God, or whatever else you use, provides us with an objective base from which to build our morality. It is something outside of and seperate to mankind, although he must find his place in it. That is what many of us here have been trying to point out to you, Laurie. Now go back again to
momor’s post. It tells us that objectivity is thrown aside by positivism and subjectivism. The love for one goat and being blind to what is wrong with that goat, will cause you to lose your goat farm.
D/S – enjoying your posts
Gay sex is unnatural using the term as defined by Natural Law morality. However the point that needs proving is. ‘given it is unnatural, why is it also wrong?’. [No convincing answer so far]
Laurie, lots of convincing Natural Law answers have been given. You just don’t accept them because you are questioning the validity of Natural Law itself. You are also being blindsided by what
momor points out.
