I had to laugh at this naive post for humans almost ALWAYS treat other humans as a means to an end! A friend asked me yesterday to accompany him to a meeting tonight because he wanted company. My wife asked me the day before "to help" her pull her cell phone charger out of the wall because she wanted to stow it. My boss asked me to provide a quote to a customer because that is how we get more business and profits.
I'm sorry if you find the Categorical Imperative, one of the hallmarks of modern deontology, to be laughably naive. Unsurprisingly, it actually applies quite well to your situations. Or at least to versions of these situations wherein someone actually is being used as a means to an end.
If your friendships are based primarily on the need to have someone--anyone--accompany you, rather than based on the genuine desire to be with that person, then yes, that is immoral. You are using someone as a means to an end, rather than as an end in and of themselves.
I'm not sure how asking someone to help you replace a battery could be considered using them as a means to an end. If you treat people as if they exist merely to help you, however, that would also be quite immoral.
As for providing quotes to customers, I have difficulty seeing how that qualifies as using someone as a means to an end unless you are in some sort of abusive work situation and are being taken advantage of in some way by your boss. That would also certainly be immoral.
So yes, a proper understanding of what is meant by the Categorical Imperative does lead to the results one would expect. I agree with you that people almost always use each other as a means to an end, though--I'd ditch Kant for St. Augustine if I really wanted to get into that problem.
- Roe v Wade discovered a pregnant woman has the right to privacy, which implies the right to kill so long as no one in government knows about it.
I haven't read
Roe since law school, so I am somewhat fuzzy on the reasoning, but the primary concern was the right to privacy in healthcare decisions, not the right to kill whomever you want as long as it happens in the privacy of your house.
Furthermore, the fact that SCOTUS hands down a ruling does not make that ruling some sort of moral discovery. There have been some notorious rulings, like
Dred Scott, and there are a number of currently controversial ones, such as
Roe and
Citizens United.
The reason the baby does not have a right to its own life is that rights pertain to actual moral agents. Recent studies suggest the human brain is not fully formed until 25 years of age. Certainly an unborn is not only NOT a rational choice maker, it is no kind of choice maker. Sure, I concede the human baby has the potential to one day be a moral agent. However, potential is not actual.
I am terribly confused. Are you suggesting that the right to life does not pertain to anyone under 25 years of age?
