Stalter isn't trying to give an out. What you're trying to do is fundamentally impossible, as per Immanuel Kant. You can't use your perception of reality as proof that whatever reality is in fact like matches your perception. In other words, you only ever have the perception, whatever may or may not lie "behind" those perceptions is unknowable.
And it's not like we wouldn't like to be able to rule out solipsism and external world skepticism; many have tried. I was initially fond of Ludwig Wittgenstein's private language argument, but it too fails. The only way 'out' of it is by an assumption.
