ABSTRACT
This chapter provides a change of heart in the nuclear age as the cultivation of those thoughts and feelings that would drive people to do all they could to avoid the possibility of extinction. The dread of massive ruin can and does change hearts, of course. But it may be that the greatest change can take place if the possibility of extinction dominates reflection. Resistance to this possibility can and must take many forms. The chapter proposes that the thoughts and feelings that would drive people to do all they could to avoid the possibility of extinction are those that create an attachment to existence. The preserving attachment to existence will consist in a spectatorial or observant or contemplative relation to existence as such. A change of heart is a change in the way of seeing, which will energize action that strives to avoid extinction, and will not be only a truth that one possesses for its own mental sake.
