“To make a good salad is to be a brilliant diplomatist – the problem is so entirely the same in both cases. To know exactly how much oil one must put with one's vinegar.”

Context: No need for confusion, my dear Mulgrave [... ] Beautiful wine and sour vinegar come from exactly the same source. Curiously if one leaves a bottle of wine open for long enough it will become vinegar. Happily in this house wine never survives long enough to go bad.

1961, Speech to Special Joint Session of Congress
Context: I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish. We propose to accelerate the development of the appropriate lunar space craft. We propose to develop alternate liquid and solid fuel boosters, much larger than any now being developed, until certain which is superior. We propose additional funds for other engine development and for unmanned explorations — explorations which are particularly important for one purpose which this nation will never overlook: the survival of the man who first makes this daring flight. But in a very real sense, it will not be one man going to the moon — if we make this judgment affirmatively, it will be an entire nation. For all of us must work to put him there.
