求翻译,请给个思路.Education is what survives when what has benn lear

Education is what survives when what has been learnt has been forgotten。
B。F。Skinner
教育是学过的东西被忘掉后尚存的东西。
这个是名言。
你说翻译的思路,Education is what survives,一个段,
what has been learnt has been forgotten。----The things ( that has been learnt ) has been forgotten是另一个段。
个人拙见。
