We present a class of exact spherically symmetric solutions to the constraint equations of general relativity coupled to a Klein-Gordon field. We analyze the subsequent evolution of the consistent Cauchy data represented by those solutions, showing that only certain special initial conditions eventually lead to successful inflationary cosmologies. We argue, however, that these initial conditions are precisely the likely outcome of quantum events which occurred before the inflationary era.
