The more we learn of the true nature of non-human animals, especially those with complex brains and corresponding complex social behaviour, the more ethical concerns are raised regarding their use in the service of man—whether this be in entertainment, as ‘pets,’ for food, in research laboratories or any of the other uses to which we subject them.

释义：世间不存在永远轻松顺遂的处境，也没有无法逾越的艰难困境。人生在世，自始至终都有令人快乐的事，也总有让人忧虑的事。要用平和、辩证的心态看待生活，不因一时的困难而气馁，也不因一时的安逸而懈怠。

今天很残酷，明天更残酷，后天很美好，但绝对大部分是死在明天晚上，所以每个人不要放弃今天。
