Clarity of perception and thought evidently requires that we be generally aware of how our experience is shaped by the insight (clear or confused) pr… - David Bohm

The actual operation of intelligence is thus beyond the possibility of being determined or conditioned by factors that can be included in any knowable law. So, we see that the ground of intelligence must be in the undetermined and unknown flux, that is also the ground of all definable forms of matter. Intelligence is thus not deducible or explainable on the basis of any branch of knowledge (e.g., physics or biology). Its origin is deeper and more inward than any knowable order that could describe it. (Indeed, it has to comprehend the very order of definable forms of matter through which we would hope to comprehend intelligence.)

relativity and quantum theory agree, in that they both imply the need to look on the world as an undivided whole, in which all parts of the universe, including the observer and his instruments, merge and unite in one totality. In this totality, the atomistic form of insight is a simplification and an abstraction, valid only in some limited context.

Difference exist because thought develops like a stream that happens to go one way here and another way there. Once it develops it produces real physical results that people are looking at, but they don't see where these results are coming from — that's one of the basic features of fragmentation. When they have produced these divisions they see that real things have happened, so they'll start with these real things as if they just suddenly got there by themselves, or evolved in nature by themselves.
