Abstract

To say that something is extreme, as solipsism is, implies that there exists a spectrum of which this extremity is one limit. Knowing one limit, we are then curious about the other, the opposite end of the spectrum. In many cases the answer is too well-known to cause comment: i.e., the spectrum of greyness has black as one extreme and white as the other. But in the case of solipsism neither the spectrum nor the other extreme is obvious.
