If you intend to continue using it, yes, you may photocopy the definition of "initiating" found there -- but he does want the book itself returned.
But the broader scope of the example I gave is that the anti-rapist has created a definition of right which the rapist does not accept. In order for the anti-rapist to impose his view of right on the rapist, he must initiate force. This is exactly what the rapist is doing - initiating force in order to impose his view of right on the wife of the anti-rapist - a view she does not accept.
Each wants to impose their own view of right on the other. Each is willing to initiate force to do so.
Why is one right and the other wrong?
Shalom.
