Even in science to raise fundamental questions can be very disturbing. Somebody could feel, 'I'd like to have the answer to this right away, and get … - David Bohm

If I am right in saying that thought is the ultimate origin or source, it follows that if we don't do anything about thought, we won't get anywhere. We may momentarily relieve the population problem, the ecological problem, and so on, but they will come back in another way.

it has always been both necessary and proper for man, in his thinking, to divide things up, and to separate them, so as to reduce his problems to manageable proportions; for evidently, if in our practical technical work we tried to deal with the whole of reality all at once, we would be swamped. So, in certain ways, the creation of special subjects of study and the division of labour was an important step forward.

Bohm suggests that while literal thought has been predominant since the inception of civilization, a more archaic form of perception, formed over the whole of human evolution, remains latent – and at times active – in the structure of our consciousness. This he refers to as “participatory thought,” a mode of thought in which discrete boundaries are sensed as permeable, objects have an underlying relationship with one another, and the movement of the perceptible world is sensed as participating in some vital essence. Even today, says Bohm, many tribal cultures maintain aspects of participatory thought.
