What’s your answer to my op hypothetical?
I think you have implicitly assumed what you are yet to prove
Your argument is essentially
a) A person is sick
b) A cure requires death of x million animals
c) Catholic moral theology would allow one to proceed with (b)
d) But (b) is unethical
e) Therefore the Catholic Theology is unethical
Your argument is logically flawed in that you have not yet shown (d). You already assume (b) is unethical.
As far as it goes for Catholics, they judge the ethical nature of (b) using Catholic Theology as the standard. For them, there is no issue.
If you want to disagree, you have to propose an alternate standard for your ethics and justify your authority to propose such a system of ethics so that we might need to consider what you have to say. Otherwise, we Catholics do not see the dilemma.
Now so far, different philosophers have attempted to construct morally consistent ethical frameworks to serve as ethical foundations. However, none of these standards can be shown to be authoritative with respect to reflecting reality. Hence, no one should really care about them other than for intellectual curiosity.
In short, a Catholic approaches this issue as follows
- Catholic Church is the authority one should give assent to with respect to transcendent truths
- Ethics/Morality if it exists, would need to be founded on some transcendent truths
- Thus one believes in the Catholic teachings regarding the matter
As for rejecting your proposed alternate ethical philosophies (which you probably use to determine that (b) was unethical) is as follows
- Person X has not shown any authority to speak on transcendent truths
- Therefore his ideas/thoughts/philosophies are not worthy of belief
So the only way you can show us a dilemma, is for you to show that Catholic church teaches that an Animal life is equal to a Human life. That is obviously not the case and hence there is no dilemma.
