Hmm... But this is your opinion, right? You haven't read or heard Molyneux making this point, am I correct?
But what is a "right", then? Well, I saw Molyneux questioning one person about this one time and the person didn't have the answer. I read on Ethics of Liberty the following definition:
"When we say that one has the right to do certain things we mean this and only this, that it would be immoral for another, alone or in combination, to stop him from doing this by the use of physical force or the threat thereof. We do not mean that any use a man makes of his property within the limits set forth is necessarily a moral use"- James A. Sadowsky, S.J., Private Property and Collective Ownership, em Tibor Machan, ed., The Libertarian Alternative (Chicago: Nelson-Hall, 1974), págs. 120–21.
I guess we could sum it up as "that which you can do without being considered immoral".
By this definition, I think a right as a universalizable concept and do not really differ from culture. I mean, people could have different and paradoxal opinions about it, but its validity doesn't rely on that. It is true because it is in congruence to reality [it is in congruence to reality that you can control your body without being considered immoral] and objective morality.
Agree, but this wasn't what I asked about...
I know about his and Murray Rothbard arguments, but they are different from Molyneux's arguments, which are the ones I'm interested in.
