4042. That this was merely a directing of the vessels of the memory plainly appeared, as while the vessels of the memory are directed the spirit who speaks cannot speak otherwise. It was proved also by experience in the case of spirits, that they would imperceptibly and quickly dispose the vessels of the memory, when the spirits [acted upon] could not speak otherwise, than according [to the influence]; when they attempted it others would act upon them, and there was then perceived something unpleasant and untoward [or abortive] which cannot be described. Hence it is evident, that there is a constant disposition of the vessels of man's corporeal memory, for as the vessels are disposed, so spirits speak, and so it is also that those who are in proximity cannot think otherwise, for the vessels of the memory are planes into which ideas are determined, which vessels, if they are not fitted, cannot receive, and as they are fitted, so they receive. The ideas of the proximate spirits are, as it were, bound to these.
