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 phys… - David Bohm

In a way, techniques of meditation can be looked on as measures which are taken by man to try to reach the immeasurable, i.e., a state of mind in which he ceases to sense a separation between himself and the whole of reality. But clearly, there is a contradiction in such a notion, for the immeasurable is, if anything, just that which cannot be brought within the limits determined by man's knowledge and reason.

Q: Are you saying that thought has a kind of possessive quality which stays, gets stuck, and then becomes habitual? And we don't see this? Bohm: I think that whenever we repeat something it gradually becomes a habit, and we get less and less aware of it. If you brush your teeth every morning, you probably hardly notice how you're doing it. It just goes by itself. Our thought does the same thing, and so do our feelings. That's a key point.

This proposal, of a creative plurality in scientific ideas and theories, does, however, raise a significant question: What is the relationship of science to reality? Is this plurality simply a matter of developing a number of different points of view which depend on the requirements of society or the particular preferences of the individual? If this is true, then it would appear that the idea of objectivity within science, as a means of obtaining some relative truth about nature, would no longer be valid. We suggest that there is indeed a meaning to a reality that lies outside ourselves but that it is necessary that we, too, should be included in an essential way as participators in this reality. Our knowledge of the universe is derived from this act of participation which involves ourselves, our senses, the instruments used in experiments, and the ways we communicate and choose to describe nature. This knowledge is therefore both subjective and objective in nature.
