I think that consciousness itself, when examined, does away with the possible validity of solipsism. This occurs in its becoming aware of a physical world external to itself and, soon after that, recognizing itself as awareness of and reflection upon the nature of reality {i.e., 'what-is' and how it appears}. That the above is the foundation of experience and thinking is the core of phenomenological philosophy, which begins with the analysis of consciousness in its acts of perception in and engagement with the world in which it finds itself existing. Merleau-Ponty refers to the "perceptual faith" that arise out of a phenomenological analysis of perception and its disclosures of the nature of what is real. One of the key phenomena-cum-experiences he cites is that of 'distance', perceived by a consciousness and then realized by that consciousness as it walks out into the physical world realizing what distance signifies.
