There are only two positions that an viewpoint can have in an outline:
1. The point. A viewpoint can be the point of the argument. In other words, it can go at the top of the outline.
2. A reason. The only other place a viewpoint can go in an argument outline is as a reason. In other words, it is being used to justify the point as an indented element within the outline itself.
TK an illustration showing that the outline allows for the point and then everything else is just reasons.
