The conclusion gives the overall verdict of the argument. You can also restate the ideas that you have discussed in the body paragraphs so as to make your point valid. The conclusion should also aim at motivating the reader to do research in the future. The conclusion is related to the argumentative introduction as the topic as well as the thesis statement is restated in a more convincing manner. The conclusion also gives you a platform of illustrating your decision concerning the argument in the article and why you have settled on that particular decision. Try not to introduce new ideas as they will give the readers an ideology that the article is not comprehensive enough.
Of all the Causes which conspire to blind
Man's erring Judgment, and misguide the Mind,
What the weak Head with strongest Byass rules,
Is Pride, the never-failing Vice of Fools.
Whatever Nature has in Worth deny'd,
She gives in large Recruits of needful Pride;
For as in Bodies, thus in Souls, we find
What wants in Blood and Spirits, swell'd with Wind;
Pride, where Wit fails, steps in to our Defence,
And fills up all the mighty Void of Sense!
If once right Reason drives that Cloud away,
Truth breaks upon us with resistless Day;
Trust not your self; but your Defects to know,
Make use of ev'ry Friend--and ev'ry Foe.
