Famous quotes containing the words general and/or decline:
“The general feeling was, and for a long time remained, that one had several children in order to keep just a few. As late as the seventeenth century . . . people could not allow themselves to become too attached to something that was regarded as a probable loss. This is the reason for certain remarks which shock our present-day sensibility, such as Montaignes observation, I have lost two or three children in their infancy, not without regret, but without great sorrow.”
—Philippe Ariés (20th century)
“The chief misery of the decline of the faculties, and a main cause of the irritability that often goes with it, is evidently the isolation, the lack of customary appreciation and influence, which only the rarest tact and thoughtfulness on the part of others can alleviate.”
—Charles Horton Cooley (18641929)
