Many of these ideas arose from the religious principles of Christianity, which serve as a strong socializing agent upon society. Christianity teaches that it is wrong to covet, especially the body. One begins to covet by seeing an object and then in turn desires for the possession of that object. Therefore the image of the body is especially dangerous and one is taught to fear it. These evaluations stand to repress the initial emotional response.
Curves relate to the body image for they compose the body.
This fear and repression of the emotional response to the body can be seen in the image below, for the religious images as well as the monk wear large robes that hide and obscure the curves of their bodies. Freedberg feels that this fear of the image must be overcome in order for the viewer's emotional response to prevail. Another idea that Freedberg proposes in concern to the image is the idea of efficacy. The efficaciousness of an image is largely imported through the viewer's identification with the image. An image becomes efficacious when one allows for it to take effect in their lives, which is often done on an inner-subjective level.
