The heights of the spirit can only be climbed by passing through the portals of humility. You can only acquire right knowledge when you have learnt to esteem it.
All great questions must be raised by great voices, and the greatest voice is the voice of the people - speaking out - in prose, or painting or poetry or music; speaking out - in homes and halls, streets and farms, courts and cafes - let that voice speak and the stillness you hear will be the gratitude of mankind.
