“Battle is the most magnificent competition in which a human being can indulge. It brings out all that is best and it removes all that is base.”

"The Lady Who Does Her Own Work" in The Atlantic Monthly (1864).

Context: The most magnificent drama in the last thousand years of human history is the transportation of ten million human beings out of the dark beauty of their mother continent into the new-found Eldorado of the West. They descended into Hell; and in the third century they arose from the dead, in the finest effort to achieve democracy for the working millions which this world had ever seen. It was a tragedy that beggared the Greek; it was an upheaval of humanity like the Reformation and the French Revolution. Yet we are blind and led by the blind. We discern in it no part of our labor movement; no part of our industrial triumph; no part of our religious experience. Before the dumb eyes of ten generations of ten million children, it is made mockery of and spit upon; a degradation of the eternal mother; a sneer at human effort; with aspiration and art deliberately and elaborately distorted. And why? Because in a day when the human mind aspired to a science of human action, a history and psychology of the mighty effort of the mightiest century, we fell under the leadership of those who would compromise with truth in the past in order to make peace in the present and guide policy in the future.

A Poet's Advice (1958)
Context: Almost anybody can learn to think or believe or know, but not a single human being can be taught to feel …
the moment you feel, you're nobody-but-yourself.
To be nobody-but-yourself — in a world which is doing its best, night and day, to make you everybody else — means to fight the hardest battle which any human being can fight; and never stop fighting.

Letter to Deng Xiaoping (1981)
Context: We must improve the relationship between China and Tibet as well as between Tibetans in and outside Tibet. With truth and equality as our foundation, we must try to develop friendship between Tibetans and Chinese through better understanding in the future. The time has come to apply our common wisdom in a spirit of tolerance and broadmindedness to achieve genuine happiness for the Tibetan people with a sense of urgency.
On my part, I remain committed to contribute my efforts for the welfare of all human beings, and in particular the poor and the weak to the best of my ability without any distinction based on national boundaries.

Context: If we compare one country of the civilized world with another, or one part of England with another, or one trade in England with another, we find that the degradation of the working-classes varies almost uniformly with the amount of rough work done by women. The most valuable of all capital is that invested in human beings; and of that capital the most precious part is the result of the care and influence of the mother, so long as she retains her tender and unselfish instincts, and has not been hardened by the strain and stress of unfeminine work.
