Chapter 6.—The Opinion Which
the Mind Has of Itself is Deceitful.
8. But the mind errs, when it so
lovingly and intimately connects itself with these images, as even
to consider itself to be something of the same kind. For so it is
conformed to them to some extent, not by being this, but by
thinking it is so: not that it thinks itself to be an image, but
outright that very thing itself of which it entertains the image.
For there still lives in it the power of distinguishing the
corporeal thing which it leaves without, from the image of that
corporeal thing which it contains therefrom within itself: except
when these images are so projected as if felt without and not
thought within, as in the case of people who are asleep, or mad, or
in a trance.
