Instead, I suggest that our minds extend far beyond our brains; they stretch out through fields that link us to our environment and to each other.
Mental fields are rooted in brains, just as magnetic fields around magnets are rooted in the magnets themselves, or just as the fields of transmission around mobile phones are rooted in the phones and their internal electrical activities.
As magnetic fields extend around magnets, and electromagnetic fields around mobile phones, so mental fields extend around brains.
Mental fields help to explain telepathy, the sense of being stared at and other widespread but unexplained abilities. Above all, mental fields underlie normal perception. They are an essential part of vision.
Look around you now. Are the images of what you see inside your brain? Or are they outside you – just where they seem to be?
According to the conventional theory, there is a one-way process: light moves in, but nothing is projected out. The inward movement of light is familiar enough. As you look at this page, reflected light moves from the page through the electromagnetic field into your eyes. The lenses of your eyes focus the light to form upside-down images on your retinas. This light falling on your retinal rod and cone cells causes electrical changes within them, which trigger off patterned changes in the nerves of the retina. Nerve impulses move up your optic nerves and into the brain, where they give rise to complex patterns of electrical and chemical activity. So far, so good. All these processes can be, and have been, studied in great detail by neurophysiologists and other experts on vision and brain activity.
But then something very mysterious happens. You consciously experience what you are seeing, the page in front of you. You also become conscious of the printed words and their meanings. From the point of view of the standard theory, there is no reason why you should be conscious at all. Brain mechanisms ought to go on just as well without consciousness...read more>>>...
