The child--a skilled actor ...

The child--a skilled actor with a hundred masks: a different one for his mother, father, grandmother or grandfather, for a stern or lenient teacher, for the cook or maid, for his own friends, for the rich and poor. Naive and cunning, humble and haughty, gentle and vengeful, well behaved and willful, he disguises himself so well that he can lead us by the nose.

Quotes from the same author

The court does not fly off the handle. It does not shout abuse. It speaks calmly.
 Janusz Korczak
Life never gives more than partial liberation. Achievement can never be more than fragmentary.
 Janusz Korczak
Man feels and ponders death as though it were the end, when in fact death is merely the continuation of life. It is another life. You may not believe in the existence of the soul, yet you must acknowledge that your body will live on as green grass, as a cloud. For you are, after all, water and dust.
 Janusz Korczak
