Real progress in understanding nature is rarely incremental. All important advances are sudden intuitions, new principles, new ways of seeing. We have not fully recognized this process of leaping ahead, however, in part because textbooks tend to tame revolutions...They describe the advances as if they had been logical in their day, not all shocking.

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

It's not so much that we're afraid of change or so in love with the old ways, but it's that place in between that we fear . . . . It's like being between trapezes. It's Linus when his blanket is in the dryer. There's nothing to hold on to.

General Systems Theory, a related modern concept [to holism], says that each variable in any system interacts with the other variables so thoroughly that cause and effect cannot be separated. A simple variable can be both cause and effect. Reality will not be still. And it cannot be taken apart! You cannot understand a cell, a rat, a brain structure, a family, a culture if you isolate it from its context. Relationship is everything.

Uncertainty is the necessary companion of all explorers.
