How do natural rights theories cross the is/ought divide?

I will refute this argument:

  1. Survival requires one to act in accordance to his ‘nature’.

  2. One will die if one refuses to act in accordance to his ‘nature’.

  3. It is logically contradictory for one to deny that one should act in accordance to his ‘nature’, because denying it will kill oneself.

  4. I value logical consistency, not logical contradiction. Hence, I value the third proposition.

  5. I, myself, should not deny that I should act in accordance to my ‘nature’.

  6. I value the law of the excluded third.

  7. According to the law of the excluded third, the statement “I should not deny …” implies “I should agree with …”

  8. I, myself, should agree that I should act in accordance to my ‘nature’.

  9. By definition, one who agrees to act in accordance to his ‘nature’ implies that one values ‘natural law’.

  10. I, myself, should value ‘natural law’.

The first premise is unsound because you can still survive even if you refuse to follow most of the laws of ‘nature’. You do not necessarily have to follow all of the laws of ‘nature’ to survive. So the second statement is also unsound because you will not necessarily die if you violated most, but not not all, of the laws of ‘nature’.

The neo-Aristotelian ethicists have assumed that one has to obey ‘nature’ entirely when one can just obey the necessary laws for one to survive. They have stuffed a package-deal called ‘natural law’ down our throats from this argument.

You’re making up an oversimplified argument, and then knocking it down. That isn’t reasonable, as it reduces to a red herring. That is what most of your arguments reduce to: either linguistic nitpicking or red herrings.

I classify the statement “Chocolate tastes good” as an ‘opinion’.

However, the statement “Billy likes chocolate” is a ‘fact’. So the statement “Billy likes chocolate” is a ‘proposition’.

I agree, but I think you are strawmanning the ‘emotivists’. The ‘emotivists’ believe that ‘morality reduces to emotions’ in the sense that “people have ‘feelings’ about moral statements” or “it requires empathy to derive morality.” That says nothing whether or not one should prescribe one’s ‘normative’ ‘preferences’ to others. As I said above, I disagree with ‘emotivism’ if you define it as a theory that ‘morality’ only arises from the short-term ‘gut-feelings’ of individuals, not ‘reason’. However, ‘emotivists’ themselves do not define it that way.

It really doesn’t seem that far off from the argument though.

It seems to be about what they’re saying. I don’t consider it a strawman fallacy just because the argument proposed by natural rights theorists is one that can be knocked down.

The emotions many normative statements express are more intensely felt and more general among humans than those expressed by your examples. But the are nonetheless subjective.

You make up a caricature of an opposing argument, and then you accuse AM of doing much the same.

If extreme-rationalist natural rights theories, which seem to me to be based on linguistic contrivances, are to be accepted by us as having any bearing on reality, they should at least be able to stand up to such linguistic “nitpicking”.

In other words, if you live by the syllogism, you die by the syllogism.

Great post, AM.

I have edited my post and expanded my argument. My argument represents Rasmussen’s argument on A Groundwork of Rights, except that I explicated his implicit ‘ought-assumptions’. So he has not bridged the ‘is-ought gap’ in a sense.

Thank you. I hope you find my reprentation of Rasmussen’s argument and my criticism ‘natural law’ useful.

Excellent!

AM engages in sophist linguistical nitpicking.

Pray tell, what are ‘necessary laws’ and how are they arrived at? How does one deduce that murder is bad?

I imagine the actual laws of physics - like as long as I am on Earth and not in an anti-gravity chamber, I can’t just fly off into space if I want.

There weren’t any of AM’s posts on that page you link to, AC.

I can perhaps see AM’s linguistic denial of the means/ends dichotomy as perhaps a bit much. But again, your theory lives by “word-fu”, so it must die by it as well.

Lilburne,

Do you fancy commenting on my attempted defence of natural rigths based on the argument that nature is good I posted a page or so back?

I’ll reply to AM response to my criticism of emotivisim when I’ve got sufficient time.

Just keep going, you will see what I mean.

From physics..you can deduce that murder is bad? Spin this one out for me.

I feel it will be akin to: From the experimentation of the famous string-theory, I can deduce specific Chinese Chi spots on your body.

Lilburne,

It seems that you missed this response:

I’m not sure what you think an “ought” is. I’m pretty sure it’s just an expression of valuing one action over another, in which case, I’m right. Also, I think you are assuming that it is only the content of your arguments that is under dispute. It is actually what is implied by the fact that you are arguing that makes the difference.
