The primary source document that is made use of here is the actual images from the image database of the divisions. The use of actual images combined with critical analysis literature from secondary sources makes the argument quite objective. The author also makes use of direct narratives from the people involved. This adds a better degree of authenticity to the argument the author is trying to make.
The author, in order to prove his viewpoint on the images of the division, presents evidence with the images from the division themselves. The author argues that although it is usually expected that what one sees with their eyes is true, it is not the case when the images are considered. For instance, looking at the images one can see the primitive character of the Inuit is seen to be over emphasized in the images. Author presents a photo story that was created in the year 1964. The photo story was one where the representations of the Inuit fisherman appears to be taken to such an extent the audience would focus on the primitive aspect. The primitive aspects are sold more in context here.
This is not a true image, even though the picture itself is not altered. The way the picture story has been created gives information that is not exactly true to an audience. Only the primitive, non-science lacking methods of the Inuit are presented in such a picture story. The evidence that has been provided in order to structure the argument is solid. The examples are actual examples and the reader will be able to check up the author’s arguments against the actual works in order to further verify the claims made. This adds much validity to the arguments.
