"We could not have known and have only just learned–perhaps mostly from children from two to five–that a new kind of relationship between people in groups is brought into being by SX-70 when the members of a group are photographing and being photographed and sharing the photographs: it turns out that buried within all of us–God knows beneath how many pregenital and Freudian and Calvinistic strata–there is latent interest in each other; there is tenderness, curiosity, excitement, affection, companionability and humor; it turns out that in this cold world where man grows distant from man, and even lovers can reach each other only briefly, that we have a yen for and a primordial competence for a quiet good-humored delight in each other: we have a prehistoric tribal competence for a non-physical, non-emotional, non-sexual satisfaction in being partners in the lonely exploration of a once empty planet."
