  No one has seriously defended the over-population solution to the problem of the many. Hudson (2001: 34) attributes it to David Lewis, but Lewis says he is rejecting 5 not rejecting 2. As Lewis says, he is interested in a solution that, “concedes that the many are [clouds] but seeks to deny that the [clouds] are really many.” (On the other hand, if rejecting 5 is just incoherent, then it is not unfair to interpret Lewis as rejecting 2.)
