am, there is nothing at all which gives me assurance of their truth beyond
this, that I see very clearly that in order to think it is necessary to
exist, I concluded that I might take, as a general rule, the principle,
that all the things which we very clearly and distinctly conceive are
true, only observing, however, that there is some difficulty in rightly
determining the objects which we distinctly conceive.

In the next place, from reflecting on the circumstance that I doubted, and
that consequently my being was not wholly perfect (for I clearly saw that
it was a greater perfection to know than to doubt), I was led to inquire
whence I had learned to think of something more perfect than myself; and I
clearly recognized that I must hold this notion from some nature which in
reality was more perfect. As for the thoughts of many other objects
external to me, as of the sky, the earth, light, heat, and a thousand
more, I was less at a loss to know whence these came; for since I remarked
in them nothing which seemed to render them superior to myself, I could
believe that, if these were true, they were dependencies on my own nature,
in so far as it possessed a certain perfection, and, if they were false,
that I held them from nothing, that is to say, that they were in me
because of a certain imperfection of my nature. But this could not be the
case with-the idea of a nature more perfect than myself; for to receive it
from nothing was a thing manifestly impossible; and, because it is not
less repugnant that the more perfect should be an effect of, and
dependence on the less perfect, than that something should proceed from
nothing, it was equally impossible that I could hold it from myself:
accordingly, it but remained that it had been placed in me by a nature
which was in reality more perfect than mine, and which even possessed
within itself all the perfections of which I could form any idea; that is
to say, in a single word, which was God. And to this I added that, since I
knew some perfections which I did not possess, I was not the only being in
