same manner when awake; as when persons in the jaundice see all objects
yellow, or when the stars or bodies at a great distance appear to us much
smaller than they are. For, in fine, whether awake or asleep, we ought
never to allow ourselves to be persuaded of the truth of anything unless
on the evidence of our reason. And it must be noted that I say of our
reason, and not of our imagination or of our senses: thus, for example,
although we very clearly see the sun, we ought not therefore to determine
that it is only of the size which our sense of sight presents; and we may
very distinctly imagine the head of a lion joined to the body of a goat,
without being therefore shut up to the conclusion that a chimaera exists;
for it is not a dictate of reason that what we thus see or imagine is in
reality existent; but it plainly tells us that all our ideas or notions
contain in them some truth; for otherwise it could not be that God, who is
wholly perfect and veracious, should have placed them in us. And because
our reasonings are never so clear or so complete during sleep as when we
are awake, although sometimes the acts of our imagination are then as
lively and distinct, if not more so than in our waking moments, reason
further dictates that, since all our thoughts cannot be true because of
our partial imperfection, those possessing truth must infallibly be found
in the experience of our waking moments rather than in that of our dreams.



PART V

I would here willingly have proceeded to exhibit the whole chain of truths
which I deduced from these primary but as with a view to this it would
have been necessary now to treat of many questions in dispute among the
earned, with whom I do not wish to be embroiled, I believe that it will be
better for me to refrain from this exposition, and only mention in general
