This book contains of a description of how we see, think and make art which depends on the fact that we do not the world directly from our eyes. We see a picture of the physical world that your brain makes in your head which I call the visual world. You are not aware of this fact because your brain makes you think you see the world directly from your eyes. This illusion is essential because you depend on your visual world to get around in the real world that does not diminish the scale. Using light waves projected by the lenses of your eyes onto the cells of your retinas your brain produces your visual world in the form of a lens projected picture using lines, shapes, surfaces, forms, space and colors. You can tell your visual world is lens projected picture by its diminishing scale. Ironically the existence of this illusionary visual world proves the existence of the underlying real world. I use the term vision for the neural process that produces that produces your visual world in contrast with the external physical process that projects light waves onto your retinas which I call eyesight. Your brain's amazing ability to make a visual world seems rooted in an underlying neural process modeled after the linear geometry of eyesight. Your experience of the visual world includes your visual self. Your presence in relation to the visual world includes the parts of yourself you can see and feel. You can tell they are lens projected by your hand growing smaller when you move it away. You see your visual world and experience your other senses in relation to your visual self. Your awareness of your visual world relative to your visual self constitute consciousness making vision a primary function of your brain. It stands to reason that a visual center of being came into existence through evolution some six hundred million years ago with the development of eyes and eyesight. Eyes would have not been of use if this were not so.
