He who remembers from day to day what he has yet to learn, and from month to month what he has learned already, may be said to have a love of learning.
He who knows much about others may be learned, but he who understands himself is more intelligent. He who controls others may be powerful, but he who has mastered himself is mightier still.
The faculty for remembering is not diminished in proportion to what one has learnt, just as little as the number of moulds in which you cast sand lessens its capacity for being cast in new moulds.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
PHILISTINE, n. One whose mind is the creature of its environment, following the fashion in thought, feeling and sentiment. He is sometimes learned, frequently prosperous, commonly clean and always solemn.
