That is the underlying principle of Objectivist Ethics
(as well as most other ethical systems, when you come right down to it).

It is WRONG to force someone to do something against his "will".
It is WRONG to coerce a human being to put aside what his MIND is saying,
	to betray his fundamental survival mechanism
	(to act against the reasoning of his own mind).

Threatening another person with death or permanent injury
(or even with pain, which tells the mind something is wrong)
is -- to use a dramatic word - EVIL.

It is the fundamental EVIL, 
	because life is a fundamental meta-value
	and it is therefore anti-life.
Anti-mind IS anti-life.
	(But enuf of Obj. Eth.)

If u want to get me to do something,
	you must get me to CHANGE MY MIND.
That is the ONLY ethical way to get me to do it.

Anything else is purely EVIL.



That is why PERSUASION is so important.

Words are the most effective form of persuasion.
That is why the word IS mightier than the sword.
