这不是使我们躁动不安和不满意的蛮族本能。我会告诉你什么是：这是人的最高目标 - 成长和进步的必要性。 。 。找到新事物。 。 。扩展。以不断发展的方式分散，到达领域，经验，理解和生活。抛开例行和重复，以脱离无意识的单调并向前推进。继续前进。 。 。
(It isn't a brute instinct that keeps us restless and dissatisfied. I'll tell you what it is: it's the highest goal of man - the need to grow and advance . . . to find new things . . . to expand. To spread out, reach areas, experiences, comprehend and live in an evolving fashion. To push aside routine and repetition, to break out of mindless monotony and thrust forward. To keep moving on . . .)
