Famous quotes containing the word stages:
“Whoe’er has travelled life’s dull round,
Where’er his stages may have been,
May sigh to think he still has found
The warmest welcome, at an inn.”
—William Shenstone (1714–1763)
“The playing adult steps sideward into another reality; the playing child advances forward to new stages of mastery....Child’s play is the infantile form of the human ability to deal with experience by creating model situations and to master reality by experiment and planning.”
—Erik H. Erikson (20th century)
