Dan, the majority of our thoughts are not verbalized. The mind is far more complex than you are imagining. Imagine what is involved in a baseball player diving for a catch in center field. From the crack of the bat, one must decide where that ball is going to fall, how fast to run, where to dive, the angle of the mitt and so forth. The same can be said of driving a car in traffic or even the simple act of eating your soup with a spoon takes a horriffic amount of calculation. If you don't believe it, try programming a robot to do that task
Language and logic are tools used by humans, and perhaps other critters to retain knowledge from generation to generation and to help solve puzzles, such as where did Fido hide his ball.
Right brain/left brain activity seems to be specialized as two different kinds of skills. If you want to have a bit of fun, first look at a picture magazine normally, and then turn it upside down and look at the pictures. You will see an entirely different level of detail. This is because your brain switches from the left (comprehension) to the right side, which tends to be spatial (I can never remember which is which). You will see shadows, shading and texture when looking upside down, whereas rightside up, your mind will interpret what the object is for or what the people are doing, if they are happy or sad or whatever. There is a fun test with a twirling dancer on this subject. I posted it below. For me, the dancer twirls both ways, but often to the left. If I look off to the side or indirectly, it reverses.
