Eric Hoffer, Reflections on the Human Condition:
In a time of drastic change it is the learners who inherit the future. The learnéd usually find themselves equipped to live in a world that no longer exists.
So many people behave as if learning ought to be confined to a carefully circumscribed period of life, including many highly-credentialed and otherwise intelligent people. This has always seemed very odd to me (except perhaps during finals).
