To beat a horse for doing something that comes naturally to him, like running away from pain, is clearly the act of a brutal or crazy person.

因为马出于本能而做出诸如“因疼痛而逃跑”等行为而鞭打它们，实在是残酷或疯狂的人才会采取的行为。

The painless running put forward by the authors is not to fear of or shy away from pain, but to face the fact positively in another way.

极点和痛苦并无健康价值，无痛苦跑不是惧怕和回避痛苦，而是另一种积极面对。
