Famous quotes containing the words real and/or space:
“The dignity to be sought in death is the appreciation by others of what one has been in life,... that proceeds from a life well lived and from the acceptance of one’s own death as a necessary process of nature.... It is also the recognition that the real event taking place at the end of our life is our death, not the attempts to prevent it.”
—Sherwin B. Nuland (b. 1930)
“Play is a major avenue for learning to manage anxiety. It gives the child a safe space where she can experiment at will, suspending the rules and constraints of physical and social reality. In play, the child becomes master rather than subject.... Play allows the child to transcend passivity and to become the active doer of what happens around her.”
—Alicia F. Lieberman (20th century)
