Read this paragraph.
Of all the attributes essential to a respected man or woman or to a respected nation, the predominant characteristic is self-discipline. Laws cannot be made compelling people to suppress their desire for power or position. No method of legislating such wisdom exists. As free people, we must face a choice between two types of discipline. One is the self-discipline that is still open to us--the kind which free people and free nations exercise when they select the executives, lawmakers, and judges who will govern them and assure their protection and well-being. The second is a cold-blooded, ill-intentioned, godless form of discipline that may be thrust upon us by strangers--the discipline of force, terrorism, suspicion, and intimidation--the discipline used in China and the former Soviet Union.
Sentences two and three say that self-discipline cannot be enforced by _____.
respected man or woman
self
laws
