Famous quotes containing the words average, ground and/or pressure:
“A two-week-old infant cries an average of one and a half hours every day. This increases to approximately three hours per day when the child is about six weeks old. By the time children are twelve weeks old, their daily crying has decreased dramatically and averages less than one hour. This same basic pattern of crying is present among children from a wide range of cultures throughout the world. It appears to be wired into the nervous system of our species.”
—Lawrence Kutner (20th century)
“Every act of the man inscribes itself in the memories of his fellows, and in his own manners and face. The air is full of sounds; the sky, of tokens; the ground is all memoranda and signatures; and every object covered over with hints, which speak to the intelligent.”
—Ralph Waldo Emerson (1803–1882)
“Today’s pressures on middle-class children to grow up fast begin in early childhood. Chief among them is the pressure for early intellectual attainment, deriving from a changed perception of precocity. Several decades ago precocity was looked upon with great suspicion. The child prodigy, it was thought, turned out to be a neurotic adult; thus the phrase “early ripe, early rot!””
—David Elkind (20th century)
