Upon looking at the picture further, one might notice two heads silhouetted and facing each other. By reversing the figure and the ground, the drawing illustrates the theory that the whole is different from the sum of its parts. The artist known as M.C. Escher was also very famous for conceptualizing such in-depth drawings of the same affect, with massive rooms of intertwining stairways for instance, not facing any direction approved by the laws of physics. But things perceived in the way such as these drawings and as the vase example are perceived rarely happen in our reality because our perceptions have been tuned to be remarkably stable, just as we know the physical world around us to be. This stability of how we see the world is derived from language. .
The ability we have to dissect and interpret language, along with the way we analyze it and how we use it to reference our visual perception is what separates man from the animal. We as humans are able to communicate with one another and coordinate the way we live amongst ourselves, being that our brains by common fact are known to have a larger capacity for such information as opposed to various, more primal beings on this earth. We are able to achieve operation on this more complicated level of thought through our use of language.
Language, by definition, is a mode of communication where from a limited number of words, one can produce an unlimited number of sentences. From there it is we that process these word combinations and process them into various meaning. This exchange of language however does not only occur on a verbal, personal interaction level. It then continues to allow us to further advance our intelligence which then further improves our means to communicate with one another. Through knowing this, one also has the option of not only verbal interaction, but visual communication by recording symbols (what we call words) in the form of written dialect, making it possible to communicate on more than an interpersonal plane.
