Before you speak out loud to another, you often speak to yourself, running routines of phrases past your own internal judge to decide whether your plan is appropriate, how it will be interpreted, whether it communicates what you intend to communicate.
The part of your mind, then, that formulates speech, must be a different part from that which interprets it. And they communicate to one another by this artificial form of speech, wherein the rest of your body does not participate.
But is the purpose of the internal voice only to formulate what will soon be said, or are there alternative purposes? I sometimes think to myself without ever planning to speak to another. I use my language to analyze my other experiences, and to weigh decisions internally. Language and this internal voice, then, are a vital part of my conduct. Through this internal voice, I perform rational operations.
The voice may be expressed in written form, as it is here in this blog. Or it may be expressed in spoken language. Does it play a part, though, in other forms of internal expression? Is Picasso's work an expression of his internal voice? Did he verbally reason with himself about the colors, texture, or form of his work?
