"We can never tell whether a child has been rightly prepared for life
until he or she is faced with a difficulty. This is true even
regarding a small baby. As long as individuals, young or old, are not
challenged--put through a test, we might say--we know practically
nothing about their prior emotional-social training and present
capability. Therefore, life-tests are always necessary if we are to
understand children."
