Just as pathos is frequently an effective hook to introduce your essay, it is, more often than not, the most powerful approach to concluding it. Writers often want to get their readers to feel something before they ask for them to take some kind of action. Look at the conclusion of Yousafzai’s speech, which is filled with appeals to emotion:

Dear brothers and sisters, we must not forget that millions of people are suffering from poverty, injustice and ignorance. We must not forget that millions of children are out of schools. We must not forget that our sisters and brothers are waiting for a bright peaceful future.

So let us wage a global struggle against illiteracy, poverty and terrorism and let us pick up our books and pens. They are our most powerful weapons.

One child, one teacher, one pen and one book can change the world.

Education is the only solution. Education First.

Notice, too, that Yousafzai’s conclusion includes a call to action—“So let us wage a global struggle against illiteracy. [. . .]” In addition to pathos, a good conclusion to an argument usually includes a “So what?” statement that tells readers what you want them to think about, or do. What reforms should take place? What studies should be conducted? What viewpoint should be re-evalutated? What programs should be funded? This is a final opportunity for you to connect directly with your readers.
