It must be concluded from this that if the blood is very refined, there will be abundant animal spirits in the brain, whereas if it is coarser, there will be only a little; if the blood is composed of panicles that are very easily inflamed in the bean, or well adapted to movement, the spirits in the brain will be extremely heated or agitated; that if, on the contrary, the blood is not sufficiently fermented, the animal spirits will languish, inactive and powerless; and finally, that, depending on the stability of the blood panicles, the animal spirits will be more or less stable themselves, and as a result, move more or less forcefully.
