These two works belong to that group of books written by one of this century's fiercest and most devoted child advocates. In the first, Korczak uses fiction to reveal the joys and sorrows of a child, a ten-year-old, juxtaposing them against the feelings of an adult as they both react to two days of adventure spent together. Two prominent themes in his writing are the exploration of the place of children in an adult world and the examination of the treatment and regard children are accorded in that world. In his second book, Korczak spells out his 'Magna Charta Libertatis' in defense of the child's right to respect, right to be him or herself, and, most importantly, right to respect for the strenuous effort expended in the process of 'growing up.'
