最好带着某种激情的全部荣耀勇敢地进入另一个世界，而不是随着年龄的增长凄凉地褪色和枯萎。
Better pass boldly into that other world, in the full glory of some passion, than fade and wither dismally with age.
无论是正确的还是错误的，经济学家和政治哲学家的思想都比通常理解的有力。确实，世界不受其他任何事物统治。自信不被知识分子影响的那些所谓务实的人，往往只是几个过时经济学家思想的奴隶。（Concluding Notes. p. 383-384）
人类最后的自由是在任何特定环境下选择自己态度的能力。

处于逆境中，就好比周身都扎着针、敷着药；冥冥中却能磨炼人的意志、培养高尚的品行。处于顺境中，就好比被各种各样的兵器包围；冥冥中掏空了身体，消磨了向上进取的意志。
The secret of change is to focus all of your energy not on fighting the old, but on building the new.
