“The sword of destiny has two edges. You are one of them.”

University Graduation address (2 July 1963), published in Important Utterances of H. I. M. Emperor Haile Selassie I, 1963-1972 (1972), p. 22.
Context: Education is a means of sharpening the mind of man both spiritually and intellectually. It is a two-edged sword that can be used either for the progress of mankind or for its destruction. That is why it has been Our constant desire and endeavor to develop our education for the benefit of mankind.
A qualified man with vision, unmoved by daily selfish interests, will be led to right decisions by his conscience. In general, a man who knows from whence he comes and where he is going will co-operate with his fellow human beings. He will not be satisfied with merely doing his ordinary duties but will inspire others by his good example. You are being watched by the nation and you should realize that you will satisfy it if you do good; but if, on the contrary, you do evil, it will lose its hope and its confidence in you.
