The way I have found of overcoming this dilemma consists
primarily in uttering words to express my appreciation and my
gratitude, my main purpose, with the help of those words, being to
stress the importance of the contributions, many of them anonymous,
which have been made to my practical and theoretical work
alike, and to offer sincere thanks to all those to whom I owe a debt of
gratitude. It is a fact that none of what I did a long time ago and am
continuing to strive to do in education in my own country and
elsewhere can be understood unless consideration is given to the
historical, social, cultural and political circumstances surrounding
my work.
