Have you ever tried to watch yourself mentally when your attention has not been set on some definite problem for concentration? I suppose most of you are familiar with this, although perhaps only a few have systematically watched it in themselves.
You are no doubt aware of the way we think by chance association, when our thought strings disconnected scenes and memories together, when everything that falls within the field of our consciousness, or merely touches it lightly, calls up these chance associations in our thought. The string of thoughts seems to go on uninterruptedly, weaving together fragments of representations of former perceptions, taken from different recordings in our memories. And these recordings turn and unwind while our thinking apparatus deftly weaves its threads of thought continuously from this material. ~ G
