自由
The highest activity a human being can attain is learning for understanding because to understand is to be free.
Human freedom is bounded by its choices.
I declare: freedom is the ultimate goal of life.
Freedom and responsibility are inseparable.
Freedom is not the choice, but the chance to choose.
Freedom is the greatest fruit of self-sufficiency.
Liberty consists in doing what one desires.
The only freedom which deserves the name is that of pursuing our own good in our way， so long as we do not attempt to deprive others of theirs or impede their efforts to obtain it.
Every law is an infraction of liberty.
