| NECESSITY | 需求 |
| Man cannot be free if he does not know that he is
subject to necessity, because his freedom is always won in his never wholly successful
attempts to liberate himself from necessity. Hannah Arendt 人若不知自己受制於必然性，就不能得自由，因為他的自由，總是在他那永不完全成功的、試圖從必然性中掙脫的努力中贏得的。 |
| Necessity does everything
well. Ralph Waldo Emerson 人在沒有退路時，最能把事情做好。 |
| Necessity never made a good bargain. Benjamin Franklin 迫切的需求，談不出好條件。 |
| Necessity is the mother of
attraction. Luke Mckissack 需求是吸引力之母。 |
| Only useless things are indispensable. Francis Picabia 只有無用的東西是不可缺少的。 |
| Necessity is the mother of
invention, it is true -- but it's father is creativity, and knowledge is the midwife. Jonathan Schattke 需要是發明之母，此話不假；可是還要加上創意的父親及知識的接生婆。 |
| I don't think necessity is the mother of invention -
invention, in my opinion, arises directly from idleness, possibly also from laziness. To
save oneself trouble. Agatha Christie (1890 - 1976), An Autobiography, 1977 我不認為需要是發明之母——依我看，發明直接源自於清閒，可能也源自於懶惰。說穿了，就是為了替自己省麻煩。 |
| Evil when we are in its
power is not felt as evil but as a necessity, or even a duty. Simone Weil, Gravity and Grace, 1947 當我們身處邪惡的掌控中時，我們並不覺得它是邪惡的，反而視之為必須，甚至是責任。 |
| Vacation used to be a luxury, however, in today's
world, it has become a necessity. Author Unknown 在以前，休假是奢侈的，在今天卻成為必須的。 |
