@oristarA,
Quote:Failed to get "an action could not be restricted because it violated the conventions or morals of a given society" clearly.
He thinks it is an illegitimate limitation on liberty to prohibit something merely because it violates morals or convention. According to Mill, the only justification for such restraints is self-protection from (real) harm.
Quote: (1) Does "an action" refer to "giving offense to"? (While this action constitutes/forms "harm" to some people, Mill doesn't consider that it really harm)
No. Giving an offense would be an example of such an action, but it is not what the word "action" specifically refers to in this sentence. It's broader than that.
Quote: (2) Does "giving offense to" mean "offending"?
Right, that's what it means here. Personally I would note a difference between "giving" offense and "taking" offense, but that's not an issue here.
Quote: (3) Because such action is among natural qualities of human nature, it cannot be restricted, even though it violates the conventions or morals of a given society?
No, I don't think his argument rests on what he considers to be "natural qualities of human nature."
Again, his main thesis is:
Quote:The sole end for which mankind are warranted, individually or collectively, in interfering with the liberty of action of any of their number, is self-protection...Over himself, over his own body and mind, the individual is sovereign
To paraphrase: Don't try to tell me what to do, say, or think if I'm not harming you.
