Upon further analysis of the article, "The Role of Light to Sight", I realized that light moves in all directions from each point is not mentioned in the article. The idea that rays move from a luminous source to an illuminated object is clear, but there is no discussion as to why every one in a room can see the illuminated object. It is impossible for 50 people to stand in the same place, but regarless of where they are standing, they are all able to see a spot from a laser on the way. This is a result of many rays being projected from te luminous source, then reflected off of the illuminated object, from numerous angles. If the article had discussed this more thoroughly, a better understanding would have ocurred.
