Annie Dillard opens the discussion for a way to see. In the process, there are a number of lessons we are able to learn from this. In the first instance, many of us see without the effort, especially when we are unrestricted, for example, when we are children. Somehow, we loose the ability to see without effort. As she says: “I used to be able to see flying insects in the air But I lost interest, I guess, for I dropped the habit.” This is even though there is the matter of “now-you-see-it, now-you-don’t affair” to contend with. By keeping to effortless “seeing” we are bound to see the world in a way that is not “naturally obvious.”
Dillard’s lessons in seeing apply also to the way in which we observe color, and light. Even so, darkness creates a different way of seeing, in that it changes everything into shadows. Van Gogh stated: “a great deal of light falls on everything.” Light plays a huge role in what we see a d the way we see it. As she continues to quote form Stewart Edward White, as he speaks of seeing deer: “As soon as you can forget the naturally obvious and construct an artificial obvious, then you too will see deer.” It is especially the difference between the “naturally obvious” and the construct “artificial obvious.”
Dillard also speaks of the greatest of assets; that of “foreshortenings and depths.” These are the aspects that make the eye adjust to the small and the large, to the distant and the near. We often see the very broad sphere with the naked eye, as she puts it: “With the naked eye I can see two million light years to the Andromeda galaxy.” However, we often see the larger picture, but are often stumped by the minute, and the close by, therefore thinking that we are not seeing anything at all. We end up echoing Dillard’s words: “I’m blind as a bat.”
What does the work with the blind teach us about how we perceive space?ANNIE DILLARD READINGFile
Dillard comments are from the book Space and Sight by Marius von Senden in pointing out how we perceive space. It reflects on medical procedures that were performed on cataract-blinded patients. The results of these procedures allowed patients to be able to see, but they often lacked the ability to have the knowledge of what space is. This is in terms of how a seeing person perceives space. Space has size, form, and distance (depth). Once the patients were able to see, they could not understand depth. This also meant that they could not determine height and distance.
Thus, what this means is that, the normal seeing person would understand the space around him or her in terms of these characteristics (as mentioned). We perceive space in front of us, as well as behind us. As the following example illustrates, that one of the patients “gradually comes to realize that there is also a space behind him, which he does not see.” We know that when we walk into a room, the space surrounds us; that is, behind in front as well as above us.
As seeing people, we are used to the expanse of our space, but very often, the blind person, who obtains vision afterward, cannot perceive of the vastness of the world around them. There are those who find their newly acquired vision a wonderful adventure, and can teach us how to see by picking up on all the detail in, for example a grapes: “a boy calls out, ‘It is dark, blue and shiny It isn’t smooth, it has bumps and hollows.’” They are often surprised and astonished at the beauty of everything, teaching us to look more carefully at what we are seeing (looking at). By understanding how they saw the world before, and how they saw the world after, should motivate us into seeing the world in that light of wonderment and new discovery each day.
