Using the formalism of Boucher we derive the conditions under which gravity can stabilize otherwise metastable or unstable scalar field configurations. For the case of a double-welled potential we rederive the stability criteria first obtained by Coleman and DeLuccia. Our derivation does not require the assumption of O(4) symmetry or the thin-walled approximation used in their work. We also give the conditions for which gravity can stabilize the symmetric points of general quartic potentials and of a Coleman-Weinberg potential.
