Famous quotes containing the word essential:
“In order for an individual to partake of the world and contribute to it in a healthy way, he first needs to view that world as a basically kind, friendly, and supportive place. Such an outlook begins to be formed during infancy. It’s essential that the baby establish a fundamental trust in his environment. The infant needs to learn that the world is a nurturing place where his needs will be met.”
—Saf Lerman (20th century)
