The more one knows, the more it is increasingly realized what is unknown—and, in certain cases, what is finally perceived as unknown can take on awesome proportions.
The larger or more awesome an unknown is, the less likely it will be perceived as such, if at all.
It is said that someone once asked a fish to describe everything in its environment, and the fish responded by describing everything but the water.
If one asks a human specimen to describe its environment, a long list of this or that will download, and the chances are very good that consciousness will not appear on the list.
Like the fish’s water, consciousness is the FIRST environmental aspect a human specimen exists within.
