ABSTRACT
Jean Piaget begins his Introduction to the UNESCO book of Selections from Comenius with these words : ‘Nothing is easier, or more dangerous, than to treat an author of three hundred years ago as modern and claim to find in him the origins of contemporary or recent trends of thought’. This warning must be kept in mind, also, when he is criticized for faults and limitations which properly belong to his age and profession. He was a child of his time. In some respects he was even behind the more advanced thinking of his time and he was not able to emancipate himself altogether from the traditions which he inherited.
