If we want to improve the world we cannot do it with scientific knowledge but with ideals. Confucius, Buddha, Jesus and Gandhi have done more for humanity than science has done. We must begin with the heart of man-with his conscience-and the values of conscience can only be manifested by selfless service to mankind. In this respect, I feel that the Churches have much guilt. She has always allied herself with those who rule, who have political power, and more often than not, at the expense of peace and humanity as a whole.
