十九章是本书的最后一章，秉持作者的一贯水准，不说废话，不说无用的话，负责任的写下每一个字。在第一段作者就写到when you read the previous chapter, it might have seemed an appropiate place to conclude the book.
Why, then, has this chapter been included? The simple answer is because thoughtful judgments deserve to be shared, and the way they are presented can strongly influence the way others react to them.
紧接着作者就告诉你，说服他人不是强行灌输自己的观点，没人喜欢被“接受”。只有自己的观点有理有据，以合适的方式陈述，才是有效的。十一条指导一一陈列：
1. Respect your audience
2.understand your audience's viewpoint
3. Begin from a position you have in common with your readers.
4. Take a positive approach
5. Understate your argument whenever possible.
6. Concede where the opposing side has a point
7. Don't ignore any relevant facts
8. Don't overwhelm your readers with arguments
9.Focus on the argument best calculated to persuade your audience
10. Never use an argument you do not believe is sound or relevant
11. Allow time for your view to gain acceptance.
作者通篇在告诉读者如何批判思维。但是我个人在阅读的过程中，我感受到的是自己的对事物判断的价值观的改变。作者的中心思想-是什么就是什么，不要自欺欺人，也不要妄想可以瞒天过海。不懂就是不懂，不必为此产生不必要的羞耻心，想法，我们要正视问题本身。当我们能以正常的心态看待自己，推己及人，对待他人，也要以平常心看待，他人有过失但是有值得自己尊重的观点。对于事物的本质的追求是一种信仰和坚持，不会一蹴而就，但是以正确的思维模式去实行，终归可以一步步接近事实。实践之后再看书中指导，之后再实践。将逻辑思维的锻炼看成一个长期的过程，不要急躁也不要气馁。
