"dubito, ergo cogito, ergo sum"
I am wiser than this
man, for neither of us appears to know anything great and good;
but he fancies he knows something, although he knows nothing;
whereas I, as I do not know anything, so I do not fancy I do.
In this trifling particular, then, I appear to be wiser than he,
because I do not fancy I know what I do not know.
