I warned especially against phrases, often found in the physical literature, such as ‘disturbing of phenomena by observation’ or ‘creating physical a… - David Bohm

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.

The way we start a dialogue group is usually by talking about dialogue – talking it over, discussing why we’re doing it, what it means, and so forth. I don’t think it is wise to start a group before people have gone into all that, at least somewhat. You can, but then you’ll have to trust that the group will continue, and that these questions will come out later. So if you are thinking of meeting in a group, one thing which I suggest is to have a discussion or a seminar about dialogue for a while, and those who are interested can then go on to have the dialogue. And you mustn’t worry too much whether you are or are not having dialogue – that’s one of the blocks. It may be mixed.

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.)
