J. H. Hopkins, Popular Science Monthly (1880)
“ If he may die for the happiness of a million, may he die for the happiness of a thousand? If he may die for the happiness of a thousand, may he die for the happiness of ten? If he may die for the happiness of ten, may he die for the happiness of one? At what point does the happiness of others accumulate to such an extent as to exceed in value a human life? ”
