"Decisions are difficult for many reasons, some reaching down into the very socket of being. John Gardner, in his novel Grendel, tells of a wise man who sums up his meditation on life's mysteries in two simple but terrible postulates: "Things fade: alternatives exclude." Of the first postulate, death, I have already spoken. The second, "alternatives exclude," is an important key to understanding why decision is difficult. Decision invariably involves renunciation: for every yes there must be a no, each decision eliminating or killing other options (the root of the word decide means "slay," as in homicide or suicide). Thus, Thelma clung to the infinitesimal chance that she might once again revive her relationship with her lover, renunciation of that possibility signifying diminishment and death."
