Conjecture: addiction is the result of the entrenchment of a conflict between two or more preferences in a mind.
Picture a smoker who wants to give up smoking but also really enjoys smoking. Those preferences conflict.
If the conflict is entrenched, then both preferences get to live on indefinitely. The entrenchment will not let the smoker give up smoking. He becomes a chain smoker.
