[Hank Kerchief]

You cannot be certain about the nature of your existence or reality...

Every statment has meaning only if the words it is comprised of have meaning. You cannot make the above statement if you do not already know what the words, certain, nature, existense, and reality mean. If you do not know what they mean, the above says nothing. At is stands, it is a self-contradiction.
