5. Objection.
If no idea be confused, but such as is not sufficiently distinguishable from another from which it
should be different, it will be hard, may any one say, to find anywhere a confused idea. For, let any idea be as it
will, it can be no other but such as the mind perceives it to be; and that very perception sufficiently distinguishes it
from all other ideas, which cannot be other, i.e., different, without being perceived to be so. No idea, therefore,
can be undistinguishable from another from which it ought to be different, unless you would have it different from
itself: for from all other it is evidently different.
