In the military, you learn the essence of people. You see so many examples of self-sacrifice and moral courage. In the rest of life you don't get that many opportunities to be sure of your friends.
It is a mistake to make propaganda many-sided, like scientific instruction, for instance... As soon as you sacrifice this slogan and try to be many-sided, the effect will piddle away, for the crowd can neither digest nor retain the material offered.
I love those who do not first seek a reason beyond the stars for going down and being sacrifices, but sacrifice themselves to the earth, that the earth of the Superman may hereafter arrive.
War is not merely justifiable, but imperative upon honorable men, upon an honorable nation, where peace can only be obtained by the sacrifice of conscientious conviction or of national welfare.
The sacrifice which causes sorrow to the doer of the sacrifice is no sacrifice. Real sacrifice lightens the mind of the doer and gives him a sense of peace and joy. The Buddha gave up the pleasures of life because they had become painful to him.
You must be prepared for further efforts of mind and body and further sacrifices to great causes, if you are not to fall back into the rut if inertia, the confusion of aim and the craven fear of being great.
Man is not equally moral at all hours, this is well known. If his morality is judged to be the capability for great self-sacrificing resolutions and self-denial (which, when continuous and grown habitual, are called holiness)
Then from the world all spirituality will be extinct, all moral perfection will be extinct, all sweet-souled sympathy for religion will be extinct, all ideality will be extinct; and in its place will reign the duality of lust and luxury as the male and female deities, with money as its priest, fraud, force, and competition its ceremonies, and the human soul its sacrifice. Such a thing can never be.
True art and true science possess two unmistakable marks: the first, an inward mark, which is this, that the servitor of art and science will fulfil his vocation, not for profit but with self- sacrifice; and the second, an external sign, his productions will be intelligible to all the people whose welfare he has in view.
