Famous quotes containing the word process:
“To exist as an advertisement of her husband’s income, or her father’s generosity, has become a second nature to many a woman who must have undergone, one would say, some long and subtle process of degradation before she sunk [sic] so low, or grovelled so serenely.”
—Elizabeth Stuart Phelps (1844–1911)
“come peace or war, the progress of America and Europe
Becomes a long process of deterioration—”
—Robinson Jeffers (1887–1962)
“Any balance we achieve between adult and parental identities, between children’s and our own needs, works only for a time—because, as one father says, “It’s a new ball game just about every week.” So we are always in the process of learning to be parents.”
—Joan Sheingold Ditzion, Dennie, and Palmer Wolf. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 2 (1978)
