It's a curious thing because imagination proceeds from the body and at the same time it seeks to separate itself from it.That's what imagination and virtuality are: a world that could exist but doesn't; a world that proceeds from reality but that is not reality.
There is an affective virtuality, a mathematical virtuality, a scientific virtuality, an artistic virtuality. It is because this make believe world, which once more doesn't exist but could exist, proceeds from me that I like it so much and that it often interests me much more than reality itself.
In short, however this subject warrants a much longer development, the body, hence imagination, is terribly limited, but it is positive in as much as it enables the soul to live of sensibility. That will be all for today. At ease! ;-)
