Quote by Alfred North Whitehead (1861-1947)

• The only use of a knowledge of the past is to equip us for the present. The present contains all that there is. It is holy ground; for it is the past, and it is the future.

• The art of progress is to preserve order amid change.

• An enormous part of our mature experience cannot not be expressed in words.

• Wisdom alone is true ambition's aim
  Wisdom the source of virtue, and of fame,
  Obtained with labor, for mankind employed,
  And then, when most you share it, best enjoyed.

• It requires a very unusual mind to undertake the analysis of the obvious.

• But you can catch yourself entertaining habitually certain ideas and setting others aside; and that, I think, is where our personal destinies are largely decided.
