Moore's proof, theory-ladenness of perception, and many proofs

I argue that if we allow that Moore's Method, which involves taking an ordinary knowledge claim to support a substantive metaphysical conclusion, can be used to support Moore's proof an external world, then we should accept that Moore's Method can be used to support a variety of incompatible metaphysical conclusions. I shall refer to this as "the problem of many proofs". The problem of many proofs, I claim, stems from the theory-ladenness of perception. I shall argue further that this plethora of proofs for incompatible positions leads to a darker form of skepticism, one which maintains that each of the dogmatic views is probably false. We will conclude by considering various ways a Moorean might respond to these difficulties.
