The fear of uncertainty is our basic trouble. Uncertainty is the very nature of meaning and the very nature of being, for meaning is always context-d… - David Bohm

Dialogue is really aimed at going into the whole thought process and changing the way the thought process occurs collectively. We haven't really paid much attention to thought as a process. we have engaged in thoughts, but we have only paid attention to the content, not to the process. Why does thought require attention? Every thinking requires attention, really. If we ran machines withinout paying attention to them, they would break down. Our thought, too, is a process, and it requires attention, otherwise its going to go wrong.'''

By using the term 'thinking substance' in such sharp contrast to 'extended substance' [Descartes] was clearly implying that the various distinct forms appearing in thought do not have their existence in such an order of extension and separation (i.e., some kind of space), but rather in a different order, in which extension and separations have no fundamental significance.

One may perhaps usefully consider here the image of a radio receiver. When the output of the receiver 'feeds back' into the input, the receiver operates on its own, to produce mainly irrelevant and meaningless noise, but when it is sensitive to the signal on the radio wave, its own order of inner movement of electric currents (transformed into sound waves) is parallel to the order in the signal and thus the receiver serves to bring a meaningful order originating beyond the level of its own structure into movements on the level of its own structure. One might then suggest that in intelligent perception, the brain and nervous system respond directly to an order in the universal and unknown flux that cannot be reduced to anything that could be defined in terms of knowable structures.

Intelligence and material process have thus a single origin, which is ultimately the unknown totality of the universal flux. In a certain sense, this implies that what have been commonly called mind and matter are abstractions from the universal flux, and that both are to be regarded as different and relatively autonomous orders within the one whole movement. (This notion is discussed further in chapter 7.) It is thought responding to intelligent perception which is capable of bringing about an overall harmony or fitting between mind and matter.
