健康的精神寓于健康的身体， 这话虽短，但却可完全阐释人生在世幸福之真谛。这二者兼备的人，夫复何求；欠缺其中任意一个的人， 与其他任何事上都难达完美（离更好总会差那么一点点）。人的幸福或痛苦， 大部分是源于自身造就。那些没有理智指引的人永远走不到正确的道路上；而那些身体孱弱的人永远无力抬升内在（的精神或灵魂）。
A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else. Men’s happiness or misery is most part of their own making. He, whose mind directs not wisely, will never take the right way; and he, whose body is crazy and feeble, will never be able to advance in it.
