communication

In reading all of the posts I find one common goal- communication. Whether it is a specific idea, an emotive quality, critique of society, or some sense of each artist's own personality it seems as though all artists have one very common but important drive-- to communicate with others. What I don't believe can be answered, at least in a universal sense, is why an artist chooses to communicate in a visual way rather than with words, either spoken or written. Personally, I believe that in my own case it relates to the fact that I am a visual person. Often I need to see something in order to understand it. My work is a way of creating an understanding, at the fairly least it poses questions for viewers to then seek out answers. Not everyone "thinks visually", by that I mean some have a harder time accepting visual images or objects as a form of dialogue, research, etc. What is it then that makes an artist so comfortable with the idea?
