The brain's calculations do not require our conscious effort, only our attention and our openness to let the information through. Although the brain absorbs universes of information, little is admitted into normal consciousness.

New perspectives give birth to new historic ages. Humankind has had many dramatic revolutions of understanding - great uses of fire and the wheel, language and writing. We found that the earth only seems flat, the sun only seems to circle the earth, matter only seems solid.

By definition, revolutions are not linear, one step at a time, event A leading to event B, and so on. Many causes operate on each other at once. Revolutions shift into place suddenly, like the pattern in a kaleidoscope. They do not so much proceed as crystallize.

If we continue to believe as we have always believed, we will continue to act as we have always acted. If we continue to act as we have always acted, we will continue to get what we have always gotten.

The person and society are yoked, like mind and body. Arguing which is more important is like debating whether oxygen or hydrogen is the more essential property of water.

We cannot leave the trap until we know we are in it.

Our past is not our potential.
