“When a person understands this setting into single- mindedness well, his affairs will pann out. Loyalty is also contained within this single- mindedness.”

The Notebooks of Leonardo Da Vinci (1938), XXIX Precepts of the Painter

Context: In a world where there is enlightenment, intelligence, kindness, awareness of others' needs and others' well-being, there is no terrorism. And in a world of viciousness and narrow-mindedness and only one way, there will be terrorism. Our challenge, in our country, is to find a way to disagree amongst ourselves without being so awful about it.

Context: My interviews with President Lincoln and his able Secretary, before narrated, greatly increased my confidence in the anti-slavery integrity of the government, although I confess I was greatly disappointed at my failure to receive the commission promised me by Secretary Stanton. I, however, faithfully believed, and loudly proclaimed my belief, that the rebellion would be suppressed, the Union preserved, the slaves emancipated, and the colored soldiers would in the end have justice done them. This confidence was immeasurably strengthened when I saw Gen. George B. McClellan relieved from the command of the army of the Potomac and Gen. U. S. Grant placed at its head, and in command of all the armies of the United States. My confidence in Gen. Grant was not entirely due to the brilliant military successes achieved by him, but there was a moral as well as military basis for my faith in him. He had shown his single-mindedness and superiority to popular prejudice by his prompt cooperation with President Lincoln in his policy of employing colored troops, and his order commanding his soldiers to treat such troops with due respect. In this way he proved himself to be not only a wise general, but a great man, one who could adjust himself to new conditions, and adopt the lessons taught by the events of the hour. This quality in General Grant was and is made all the more conspicuous and striking in contrast with his West Point education and his former political associations; for neither West Point nor the Democratic party have been good schools in which to learn justice and fair play to the negro.

Context: The single flower contains more brightness than a hundred flowers. The great sixteenth-century master of the tea ceremony and flower arranging, Rikyu, taught that it was wrong to use fully opened flowers. Even in the tea ceremony today the general practice is to have in the alcove of the tea room but a single flower, and that a flower in bud. In winter a special flower of winter, let us say a camellia, bearing some such name as White Jewel or Wabisuke, which might be translated literally as "Helpmate in Solitude", is chosen, a camellia remarkable among camellias for its whiteness and the smallness of its blossoms; and but a single bud is set out in the alcove. White is the cleanest of colors, it contains in itself all the other colors. And there must always be dew on the bud. The bud is moistened with a few drops of water.
