The Avogadro Constant states that any constriction on all of the particles that make up a whole is a constriction to the whole itself. For example, if each particle of a ball couldn't travel faster than 35 miles per hour the ball itself would be limited to 35 miles per hour.
A perception can not find evidence of a world around it outside of it's own perception. For example, let's say you used a machine to tell you that a world was there. The only thing you really have is your perception of a machine telling you that.
Now apply the two. On one hand you have the Avogadro Constant and on the other you have the perceptions particle constriction. This means that perceptions as a whole (all perceptions) can not find evidence of a world around them outside of their own perceptions of it.
So how do we know that perception isn't the only thing there?
