Every time I asked a question, that magnificent teacher, instead of giving the answer, showed me how to find it. She taught me to organise my thoughts, to do research, to read and listen, to seek alternatives, to resolve old problems with new solutions, to argue logically. Above all, she taught me not to believe anything blindly, to doubt, and to question even what seemed irrefutably true, such as man's superiority over woman, or one race or social class over another
