Not the OP, but your question got me thinking. I think ends frequently justify means, though I’m guessing that the real question in that adage should be “does the end justify any means?”
Our entire decision system relies on endings justifying meanings. I want a steady job that pays well, so I concede to going to a 4-year institution and paying a decent amount in order for that end to be so. The end justifies the sacrifice in time and finances, so the decision is justified in my mind. If the end were that I had only obtained unemployable skills or knowledge, then that particular end would not have justified the means for me.
So I suppose that when people say the ends don’t justify the means, they’re not really saying it categorically—just that the particular ends being argued don’t justify the particular means.
With the case of animal testing to improve human quality of life, it’s hard to say. Dogs were routinely experimented on and killed to first link diabetes to the pancreas, and later to discover insulin was a substance that could be transferred to preserve life. These medical results have saved hundreds of thousands of lives in the past hundred years. Whether the neuralink experimentation is justified in its potential for quality-of-life improvements in paralysis victims years into the future really depends on where you weigh animal well-being and life in relation to future improvements to human life, as well as whether you believe their experiments are too gratuitous and could be carried out more safely/ effectively on fewer animals.
Sorry, I can't answer that as a yes/no since there is a whole package of connotation with such statement that I don't necessarily agree with in either case.
I thought my argument was clear, but I can try to make it more clear:
- I eat pork. Unfortunately because of people like me there are many many suffering pigs.
- I believe that it is more justified to make a pig suffer for neuroscience research than to be made into a McRoyal. (Let's assume that the suffering is comparable. Please also assume that the suffering is necessary for the particular research and that research has actual potential for useful applications. If there is evidence of unnecessary abuse then I'm not defending such abuse.)
- Therefore it seems silly to me to attack neuroscience researchers instead of me, an omnivore who could be vegetarian/vegan.
I understand that one can argue for both positions at the same time -- argue against research on animals and argue against eating meat. But I think the latter one is much more important than the former. And yet you probably wouldn't attack me for my meat-eating habit. (Maybe because doing so would be impolite.)
- The ends justify the means - Meaning we could justify torture if it prevents terrorism for example. Some people would consider this fine, others not.
- Some moral principles or duties have intrinsic value independent of their outcomes - For example, telling the truth might be considered right not because of its consequences, but because honesty itself is inherently valuable.
- Both means and ends matter - Actions are justified when there's moral harmony between how we act and what we achieve. This suggests that good ends achieved through ethical means have a different moral quality than the same ends achieved through harmful means.
Probably I'd put myself in the latter camps, rather than the first two. But then I haven't thought about this too deeply myself, so happy to hear the opinions of others who might have thought about it more :)
I have just refused to answer in a different reply to you, but actually when you describe it like this, the third camp resonates with me the most. So I'm with you there.
However, wouldn't most people say that? It is kind of a cop-out because it let's you decide on each moral dilemma in a case by case basis -> which I think is actually necessary since you can't say that ends justify/don't justify means blankly.
Do you by any chance know Alex O'Connor? I listened to an ethics episode of his podcast and it was quite interesting and well-spoken in my opinion. (It is about veganism again, I suppose it is a useful theme for ethical arguments.)
I believe in a true moral field that pervades reality, but I don't believe that "good" or "not good" can be expresssed in a finite sentence in some human understandable language. I believe the complexities require one to attend to the context as well as the action and so on. There's very few cases where I'd find it good to kill some human no matter the ends; but even just listening to someone patiently with attention instead of begging off due to being busy can be quite important to get right; these ordinary daily issues are where a clear feeling for the ends you live for and a feeling for your own actual physical limits on being patient or having enough energy for various tasks are useful. And I believe that two perspectives I find very useful are missing from many moral analyses: 1) my decisions change who I am, so the reason not to murder is not a strictly utilitarian balancing of the person's likely future actions, but also includes the change to my habits and tolerances, and 2) in the prisoner's dilemma, there is nothing that special about me being me - I could as easily be someone else, so when I am deciding I am picking between a world where x% of people make choice "cooperate" or x% of people make choice "defect."
This latter approach also extends very nicely to probabilistic methods - if I pass garbage on the beach, I can pick it up with probability Y%, and adjust Y so that if most a lot of people make the same choice, then all the garbage will be picked up.
